Overview of basic system operations

The System i platform is built to require only minimal effort to keep it running reliably, and most of the routine operations are performed quickly and easily when you are familiar with them. Use this information to get to know about some of the common system tasks.
Using system interfaces

Depending on the type of connection to the system and the task you need to perform, several options are available for system interfaces. You can access and use your system by the System i Navigator interface, by the character-based interface, and by wireless clients. You can access the system from character-based interfaces on an attached console or emulator session and from the graphical user interface in System i Navigator. The interface you need to use depends on your connection type to the system and the task you need to perform. This topic describes how to access the system from the character-based interface and discusses some functions of this access method.
Character-based interface
The character-based interface, available from most emulator sessions or consoles, might seem unfamiliar to people without any experience in the i5/OS operating system. The character-based interface is available from most consoles and emulator sessions connected to a system, and provides more functions than any other interface. While this type of interface might be unfamiliar at first, it includes several methods for helping new users, and a menu-based hierarchy of tasks to make finding specific functions simple. The character-based interface includes three primary displays: navigational, input, and informational. The navigational display typically consists of a list of menu options and a command line. You can use this display to find information or tasks on the operating system, and to enter control language (CL) commands. Input displays are available when the operating system requires information from you. Use this display to enter or change information. Informational displays provide system information and do not allow any interaction.
Finding functions or tasks

All system tasks are organized into categories accessible through the main menu. You can enter menu selections to move through this hierarchy until you find the task you are looking for. Different users might have different menu options available to them, depending on the security strategy and on the restrictions set by the system administrator and the active user profile. When you have found a menu option you need to use, you can enter commands at the Selection or Command prompt located at the bottom of the display. Many menu displays have a name listed in the top-left corner of the display. You can use the GO command followed by the name of the menu to access the menu display. For example, GO JOB instructs the operating system to display the Jobs menu.
Getting help
The character-based interface provides several methods for assisting users. First, online help is available for many displays by pressing the help or F1 key. You can often get help with a particular field or item by placing your cursor on it and then pressing the help or F1 key. When you are entering data, you can also get help by entering a ? in a data field. Finally, the amount and type of information displayed on the display can be controlled by changing the assistance level. The assistance level determines what version of a display you see. Many system displays have two different versions: v A basic assistance level version, which contains less information and does not use technical terminology. v An intermediate-assistance level version, which shows more information and uses technical terms. Some fields or functions are available only on a particular version of a display. The instructions tell you which version to use. To change from one assistance level to another, use F21 (Select assistance level). F21 is not available from all displays. Related concepts i5/OS commands on page 61 The operating system uses control language (CL) commands to interpret instructions from users. You need to know the basic rules for using CL, and how to get detailed help for any CL command.
Working with devices

Most of the peripheral equipment attached to the System i platform is considered a device. Every device in the system has a current status. From System i Navigator, you can work with devices. A device is a piece of equipment that is connected to your system. Most hardware, including internal processors, ports and adapters, drives, communications hardware, workstations, and printers, are considered devices. The operating system organizes these devices by their type, such as workstation or optical drive, and identifies specific devices by their resource name. For most internal devices, like processors, adapters, and ports, the operating system automatically assigns the resource name. For most external devices and some internal storage devices, the System i platform manages communication with the device through a device controller. Most devices managed through a controller have resource names defined by their device description. You can use the device type to learn its resource name, physical location, current status, and other information.
Every device in the system has a current status that describes whether it is turned on, and whether it is currently communicating with the system. Before a device can function, both this device and all devices connecting it to the system must be varied on (operational) and functioning. For example, if a communication line or network adapter is varied off, any device attached to the system through those devices cannot function. Most devices have the following possible types of status.
Table 1. Possible types of status for most devices Status Varied off Varied on (Operational) Pending Active Description The operating system has disabled the device, and it must be varied on again before communicating with the system. The operating system has enabled communications with the device, and is waiting for communications. The operating system is attempting to enable communications with the device. The device is currently busy communicating with the system, and cannot be varied off.
Other types of status are possible for some specific device types, or to indicate a specific problem. For example, a workstation that is waiting for a user to sign on will have a status of Signon display, and a device that the operating system is unable to locate will have a status of Resource not detected.
Viewing and managing devices

On System i Navigator, you can display the current status, physical location, and configuration information for devices. To work with devices in System i Navigator, expand Configuration and Service and select Hardware. To display detailed information about the device, including its model, type and serial number, physical location in the system, and logical address, right-click the device and select Properties. Additionally, System i Navigator provides many functions for managing tape devices, disk units, and pools. See the online help in System i Navigator for more information. To change the status or properties of a device, you must use the character-based interface and type go device from any command line. Related information Local Device Configuration PDF
Working with printer output

Many jobs on the i5/OS operating system result in printer output. You can find, track, and manage printer output across the system. Many jobs generate output that requires printing. The operating system handles this by creating spooled files that contain the document data and processing instructions for the print job. After creating the spooled files, the operating system sends them to an output queue. Similar to a job queue, output queues hold many spooled files until a printer becomes available. The output queue that the operating system sends the spooled file to varies according to the job attributes, user profile, and workstation settings. Before any of the spooled files can be printed, a printer device must be varied on, and a print writer started. The print writer is an i5/OS function that runs for each active printer on the system. When started, the print writer watches the specified output queue (or queues) and sends the spooled files to its printer.
Related concepts Basic printing
Managing printer output

From System i Navigator, you can find and manage printer output from two locations: basic operations and work management. v To see a list of spooled files waiting specifically for printing, expand Basic Operations, and then click Printer Output. This displays all spooled files associated with the current user. Right-click a spooled file to hold, release, move, or delete the print job, or convert it to a PDF. Additionally, you can select Properties to change many of the spooled file attributes. v To work with other print jobs, select View Customize this view Include from the System i Navigator menu. v To see a list of all output queues, expand Work Management, and then click Output queues. This will display all output queues for all users. An output queue is an object that contains a list of spooled files to be written to an output device, such as a printer. Select any output queue to display the list of spooled files for that queue.
Starting printers
From the command-line interface, you can start a printer. Before you start the printer, verify the following conditions: v The printer is turned on and ready. v The printer or print method has been configured in the operating system. To start a printer from the command-line interface, follow these steps: 1. Vary on the printer. a. Enter WRKCFGSTS *DEV *PRT command. The Work with Configuration Status display shows a list of devices. b. Enter a 1 next to the printer device description to vary on the printer. 2. Use the Start Print Writer (STRPRTWTR) command to start the print writer, and specify the printer and output queue (or queues) that the writer will service.
Starting a printer from System i Navigator

From System i Navigator, you can start a printer. To start a printer from System i Navigator, follow these steps: 1. From System i Navigator, select your system. Expand Basic Operations, and click Printers. 2. If the status of the printer (shown in the right pane) is Unavailable, right-click the printer and click Make Available. 3. Right-click the printer and click Start.
Working with storage

The system offers a wide variety of options for storing system data. Internally, the system includes disk units that can be distributed across several expansion units (also known as towers). Additionally, many options are available for working with removable media, such as tapes and optical devices. As a system operator, you might need to work with disk units and track their use across your business. Removable storage devices are frequently used for backing up the system and archiving data.

Working with the control panel

The control panel is the initial interface on your system. With the system control panel, you can determine processor activity, read error codes to help determine component failure analysis, turn the system on and off, and change initial program load (IPL) characteristics. From the control panel, you can process the following system functions: v Determine processor activity v Display and get attributes or error codes to analyze problems v Perform an IPL v Turn on or off the system You can use the physical control panel on the system or a remote control panel to perform these operations. It might be helpful to you if you set up the virtual control panel or the remote control panel. You can access control panel functions and use APIs to operate your remote control panel with a user-written program. Notes: v If you have a partitioned system, only the primary partition can access the control panel. All secondary partitions use the remote control panel through the primary partition. v The information in this topic pertains only to models 8xx and earlier. For all other models, refer to the Managing the control panel functions topic collection in the IBM Systems Hardware Information Center for more information.
Control panel concepts

This information explains the differences between the control panel options: the virtual control panel, the remote control panel, and the physical control panel. It also provides details about the functions that the control panel can perform. Types of control panels: Control panels include the virtual control panel, the remote control panel, and the physical control panel. You can use these control panels to perform almost all of the same functions. The remote control panel and virtual control panel provide a way to perform control panel functions from a PC. Physical control panel: The physical control panel is your initial interface with the system. You can use the physical control panel to perform functions, such as performing an initial program load (IPL) and turning on and turning off the system. Control panel functions range in complexity from functions that display status (such as IPL speed) to low-level service functions that only service representatives can access. Note: If the system has multiple partitions, some secondary partitions might not start if they have been set to a status of hold.
Related concepts Control panel buttons, lights, and indicators on page 12 These figures illustrate the interface for each of the control panels, including the buttons, lights, and indicators. The interface for the virtual control panel and remote control panel are identical. Related tasks Restarting and powering down a system with logical partitions Accessing control panel functions on page 15 To access the control panel functions, follow these instructions, which apply to all three kinds of control panels. Remote control panel: The remote control panel provides a way to use control panel functions through a PC. The graphical user interface of the remote control panel looks similar to the physical control panel. The remote control panel has the following characteristics: v The remote control panel is installed through Operations Console. v A directly attached remote control panel is not supported, but you can use the remote control panel with a LAN-connected console. The use of virtual control panel is supported. v You can use the interface of the remote control panel to restart and turn off the system. However, a LAN-connected remote control panel or the virtual control panel cannot turn on the system unless it is connected to the primary partition of an 8xx or earlier model and the primary partition is still active. You can use the remote control panel to perform most of the same functions as the physical control panel. v You can use remote control panel APIs to automate control of the remote control panel through a user-created program. v If your system uses a keystick, the Mode button works with the same functions as the physical control panel, depending on whether the keystick is inserted. Related concepts Setting up your control panel on page 14 Both the remote control panel and the virtual control panel are set up through an Operations Console configuration. You need to install Operations Console and configure a remote control panel or a virtual control panel to use control panel functions. Control panel buttons, lights, and indicators on page 12 These figures illustrate the interface for each of the control panels, including the buttons, lights, and indicators. The interface for the virtual control panel and remote control panel are identical. Related tasks Accessing control panel functions on page 15 To access the control panel functions, follow these instructions, which apply to all three kinds of control panels. Virtual control panel: With the virtual control panel, you can use control panel functions through a PC. The graphical user interface for the virtual control panel is identical to the user interface of the remote control panel. Also, the virtual control panel can perform most of the same functions as the remote control panel. If your system uses a keystick, the Mode button works with the same functions as the physical control panel, depending on whether the keystick is inserted.
Unlike the remote control panel, the virtual control panel cannot turn on the system. As an alternative, if you need to turn on the system at a later time, you can use the IPL scheduling function in Operational Assistant by pressing the Attention key. You can also use the GO POWER command and select option 2 (Change turn on and off schedule). Considerations for the virtual control panel If you use the virtual control panel, be aware of the following considerations: v The virtual control panel must have a direct connection to the system from Operations Console using the serial console cable. v The virtual control panel is only available while the Operations Console is connected. v You cannot use the virtual control panel remotely through a dial-up connection. v You must meet several prerequisites when installing the virtual control panel, such as a program temporary fix (PTF) for the server and service packs for the client. v If the PC has a parallel cable connection for a remote control panel, you must remove it before you can install and use your virtual control panel. v A unique service tools device profile must exist for each virtual control panel connection. v You cannot use an existing network name. v More than one virtual control panel and remote control panel can be active at the same time. v To use the mode function provided by the virtual control panel, the service tools user ID that is used to authenticate the connection must have the key privilege of partition remote panel. To verify that your service tools user ID has this privilege, see Changing the functional privileges for a service tools user ID using SST. How to choose between the virtual control panel and remote control panel The following table shows which server models are recommended for the virtual control panel and which models are recommended for the remote control panel.

Related concepts Physical control panel on page 6 The physical control panel is your initial interface with the system. You can use the physical control panel to perform functions, such as performing an initial program load (IPL) and turning on and turning off the system. Control panel functions range in complexity from functions that display status (such as IPL speed) to low-level service functions that only service representatives can access. Remote control panel on page 7 The remote control panel provides a way to use control panel functions through a PC. The graphical user interface of the remote control panel looks similar to the physical control panel. Virtual control panel on page 7 With the virtual control panel, you can use control panel functions through a PC. Control panel buttons, lights, and indicators on page 12 These figures illustrate the interface for each of the control panels, including the buttons, lights, and indicators. The interface for the virtual control panel and remote control panel are identical.
Instructions and descriptions for control panel functions

Control panel functions can be classified into three categories: normal functions, extended functions, and low-level debug functions. The remote control panel and virtual control panel can perform most of these functions. The physical control panel can perform all of them. Normal control panel functions Normal control panel functions are the most often performed functions, such as displaying IPL speed and forcing the system to perform an IPL. They also include functions such as forcing DST and forcing a main storage dump. These functions are 01 through 49. Extended control panel functions Extended control panel functions are performed less often. Only service representatives can perform these functions. Extended functions are 50 through 70. Low-level debug panel functions These are functions 57 through 70. They are performed only by service representatives. Note: The examples in the following topics show control panels with a 4-word (32 character) display. Control panels with a 1-word (8 character) display only show the first word (8 characters) of each function. Related concepts Control panel functions on page 8 There are few functional differences among these control panels. The main difference is that the physical control panel and the remote control panel, when cabled directly to the system, can turn on the system. The virtual control panel and the remote control panel, if connected through a LAN, cannot turn on the system. Normal control panel functions: These instructions show how to use normal control panel functions 01 through 49. Functions 21 through 49 are available when you select the Manual mode. The instructions you follow for function 01 or 02 depend on whether your system uses a keystick. Also, the following instructions for functions 01 and 02 alternate between systems with a keystick and systems without a keystick. To determine how to activate functions 01 and 02 on a control panel, follow these steps: 1. Does the control panel have an electronic keylock (a keystick)?
Yes Go to the next step.

Using remote control panel APIs

You can use these APIs to write a program that can access the control panel remotely. With the APIs, your program can access many commands and queries. The remote control panel function of Operations Console provides a set of APIs that system administrators can use to control the system through programs. The APIs allow custom programs to interact with the system control panel and perform many common system control panel functions. You can use these APIs only if you are using the remote control panel that is connected with the serial console cable. You cannot use these APIs with the virtual control panel or remote control panel connected with a parallel cable.
27
The interface to the remote control panel APIs is established through a standard TCP/IP socket connection. The socket connection can be implemented in any programming language that supports sockets on the Windows platform (Java , C/C++, Visual Basic to name a few). To use the remote control panel APIs, follow these steps: 1. Start Operations Console with the remote control panel function. 2. From a custom program, open a socket connection to port 2150 on the same PC. 3. Send a supported command from the set of commands that are described below (using uppercase and lowercase letters as shown for each API name). 4. Receive the byte stream that is sent back on the same socket connection. 5. Repeat steps 3 and 4 as necessary on the same socket connection. 6. Close the socket connection when done. Your program needs to interpret the byte stream that is sent back from the system. The returned byte stream consists of a predefined format, which is the same for all commands. The byte stream is at least 4 bytes long. Some commands return additional bytes. The first 2 bytes (0 and 1) will return the command status, typically successful or unsuccessful. The next 2 bytes (2 and 3) will be a 16-bit number N, which tells how many additional bytes will follow these first 4 bytes. If N is nonzero, then there will be additional information in bytes 4 through 4 + N. This information will be additional data related to the command, such as TRUE or FALSE. Note: If the command sent is not one of the command strings defined below, then the return code in bytes 0 and 1 of the return value will be 32 (0x20). This means Command not Supported. Your programs can perform the following control panel functions by using the following APIs. System power and test APIs: You can use these APIs to turn on and off the system and to perform and clear panel lamp tests. Turning on the system: To turn on the system, you can use the PowerOn API. There are no restrictions to the use of this command. This API returns the following information.
Bytes 0 and 1 16-bit return code 0 = Command successful 1 = Command unsuccessful Bytes 2 and 3 16-bit additional data length N = 0 Bytes 4 through 4+N Not applicable
Performing panel lamp test: To perform the panel lamp test, you can use the DoLampTest API. There are no restrictions to the use of this command. This API returns the following information.
28
Bytes 0 and 1 16-bit return code 0 = Command successful 1 = Command unsuccessful
Bytes 2 and 3 16-bit additional data length N = 0
Bytes 4 through 4+N Not applicable
Clearing panel lamp test: To clear the panel lamp test results, you can use the ClearLampTest API. There are no restrictions to the use of this command. This API returns the following information.
Bytes 0 and 1 16-bit return code 0 = Command successful 1 = Command unsuccessful Bytes 2 and 3 16-bit additional data length N = 0 Bytes 4 through 4+ N Not applicable
Powering off the system: To turn off the system, you can use the PowerOff API. To use this command, you must insert the keystick in the electronic keystick slot (on systems with a keystick). This API returns the following information.
Bytes 0 and 1 16-bit return code 0 = Command successful 1 = Command unsuccessful 2 = Key not inserted Bytes 2 and 3 16-bit additional data length N = 0 Bytes 4 through 4+ N Not applicable
IPL-related APIs: You can use these APIs to set initial program load (IPL) modes, types, and speed, and to start an IPL. Setting IPL mode to Manual: To set the system initial program load (IPL) mode to Manual, you can use the SetIPLModeManual API. You must insert a key to use this command (on systems with a keystick). This API returns the following information.
29

Starting and stopping the system

The System i platform is well-known for rarely needing to be stopped or restarted. However, some maintenance items or system changes might require that the system stop processing and go through an initial program load (IPL). Stopping and starting the system must be done carefully. Note: The procedures for starting and stopping the system depend on whether you have a partitioned system. The following instructions are relevant only for a system without logical partitions. If you have a partitioned system without the Hardware Management Console, see Restarting and powering down a system with logical partitions. If you have a partitioned system with the Hardware Management Console, see Partitioning with System i. Regardless of how your system environment is configured, starting and stopping the system requires careful planning to prevent data loss and to protect system integrity. The i5/OS operating system provides several methods for starting the system to allow for various amounts of interaction with the user. Note: Several system values determine the available options for starting and stopping the system.
Starting the system

Some changes to the system settings or hardware configuration require the system to go through a startup sequence called an initial program load (IPL). During an IPL, system programs load from the designated load source device in the system auxiliary storage. The system hardware is also checked. The control panel displays a series of system reference codes that indicate its current status and warn you of any problems. When the IPL is finished, the character-based interface presents the sign-on display, and users can sign on with System i Navigator. During the IPL, the control panel displays a series of system resource codes (SRCs) indicating the current system activity. There are various options for starting a system. Related information IPL system reference code (SRC) finder
Starting the system without making configuration changes (unattended IPL)

This is the most common way to start the system. Unattended initial program loads (IPLs) reset system storage and recognize any configuration changes automatically.
39
Prerequisites
This procedure assumes that the system is running, and requires that several additional conditions be met before you begin an IPL. While most of these settings are the default values, you must verify them if you are unsure. v The IPL mode for the system must be set to Normal (unattended IPL). v The Type of restart (QIPLTYPE) system value must be set to unattended (0). v Turn on any devices, such as display stations, printers, tape devices, and controllers, that you or others want to use.
Situation
Unattended IPLs reset system storage and recognize any configuration changes automatically. The amount of time required for any IPL depends on the size and complexity of the system, ranging from a few minutes to several hours. When the unattended IPL is complete, the sign-on display appears on the display station. Note: If you are working on a system that has logical partitions, you need to understand how to restart and turn off the system with logical partitions.
Performing an unattended IPL

Enter different options on the command line to perform an unattended IPL. 1. Type ENDSYS or ENDSBS *ALL on any command line and press Enter. Note: More options are available for the End System (ENDSYS) and the End Subsystem (ENDSBS) commands, for example, to set delay time. 2. Type WRKSBS to verify that the controlling subsystems have ended and are in the restricted state. The subsystems status must be RSTD. 3. Type PWRDWNSYS *IMMED RESTART(*YES) on any command line and press Enter. When the unattended IPL is done, the sign-on display appears on the display station.

Changing the system during IPL (attended IPL)

If you want to change initial program load (IPL) options, to install the operating system, to use dedicated service tools, to work with logical partitions, or to recover from a system failure, you need to perform an attended IPL. These situations might require you to enter information or change system values.
Prerequisites
This procedure assumes that the system is running, and requires that several additional conditions be met before you begin an initial program load (IPL). Most of these settings are the default values, but you must verify them if you are unsure of the current setting. v The IPL mode for the system must be set to Manual (attended IPL). v The Type of restart (QIPLTYPE) system value must be set to attended (1). v Turn on any devices, such as display stations, printers, tape devices, and controllers that you or others want to use.
Situation
If you want to change IPL options, install the operating system, use dedicated service tools, work with logical partitions, or recover from a system failure, you need to perform an attended IPL. This IPL mode requires that you respond to several prompts during the startup sequence.
Performing an attended IPL

Enter different options on the command line to perform an attended IPL. 1. Type ENDSYS or ENDSBS *ALL on any command line and press Enter. Note: More options are available for the End System (ENDSYS) and the End Subsystem (ENDSBS) commands, for example, to set delay time. 2.

Defining or changing the system at IPL: On the Define or Change the System at IPL display, you can change the system configuration, system values, user profiles, and system, network, object, or file attributes during the initial program load (IPL). This display is shown when you type Y (Yes) in the Define or change the system at IPL field on the IPL Options display. 1. Select any of the following options: v To change the way the system starts, select option 3 (System value commands). v To change any of the other options, select them before exiting and continuing the IPL. 2. When you finish using the options on this display, press F3 (Exit and continue IPL) to continue the IPL. Related concepts Changing system values during IPL on page 47 System values control information that affects the operation of certain parts of the system. On the System Value Commands display, you can change system values that affect initial program load (IPL) or other areas of the system. Editing access paths during attended IPL: Applications use access paths to determine the order of records in a database file. If the access paths have changed, use the Edit Rebuild of Access Paths display to reconstruct them. Access paths define the order that records in a database file are organized for processing by a program. If there are access paths to rebuild, the Edit Rebuild of Access Paths display is shown after the IPL Options display. Tip: Use the online help information about this display to get more information about each column and field. A message notifies you that a journal needs to perform an access path recovery. A journal is a system object. It is used to record entries in a journal receiver when a change is made to an object associated with the journal. Any access path that is recoverable (because it was recorded) is not shown on this display. The IPL threshold indicates that access paths with a sequence less than or equal to the number specified will be rebuilt at IPL time. It is a value from 1 through 99 that you can set (the default is 50). If the IPL threshold changes, all access paths with a status of IPL and AFTIPL changes to reflect the new status of the IPL threshold. v To change the sequence of access paths that are rebuilt, follow these steps: 1. Make any changes to the Seq column. 2. Press Enter. v If you do not want to change the sequence, press Enter. The Display Access Path Status display is shown if there are access paths left to be rebuilt. Tip: Press Enter to continue with the IPL from the Edit Rebuild of Access Paths display. If no access paths need to be rebuilt, the IPL continues. If you press F3 (Exit and continue IPL), the access paths are rebuilt while the IPL continues. If you press F12 (Cancel), you return to the Edit Rebuild of Access Paths display. Every 5 seconds, the display is updated with the current run time. After all the access paths have been rebuilt (access paths with a sequence less than or equal to the IPL threshold), the IPL continues. Editing check pending constraints during attended IPL:
43
Some physical files might have restrictions placed on them. These restrictions need to be verified during an initial program load (IPL). On the Edit Check Pending Constraints display, you can verify the status of these physical files. During an attended IPL, the Edit Check Pending Constraints display is shown if there are constraints to be verified. A constraint is an attribute that places a restriction or limitation on a physical file. Tip: Use the online help information about this display to get more information about each column and field. On the Edit Check Pending Constraints display, you can change the sequence (1 through 99) of the constraints to be verified. If the constraint has a sequence less than or equal to the IPL threshold, it is verified during the IPL. If a constraint has a sequence greater than the IPL threshold, it is verified after IPL. The sequence *HLD indicates that the constraint is not verified until it is changed to a number from 1 through 99. When the IPL threshold changes, all constraints with a status of IPL or AFTIPL are changed to reflect the new status of the IPL threshold. v To change the sequence of check pending constraints, follow these steps: 1. Make any changes to the Seq column. 2. Press Enter. v If you do not want to change the sequence, press Enter. The Display Constraint Status display is shown if there are constraints left to be verified. If you press F3 (Exit and continue IPL), the constraints are verified while the IPL continues. Every five seconds, the display is updated with the current run time. After all constraints with IPL status have been verified, the IPL continues. If you press F12 (Cancel), you return to the Edit Check Pending Constraints display.
Changing your system IPL from the control panel

You can specify the type of initial program load (IPL) you need to perform from the system control panel. The Increment/Decrement buttons are used to change the IPL type and mode on systems without a mode button. Use Function 02 to select the IPL type (A, B, or D) and mode (normal or manual). To select the IPL type and mode from the control panel, follow these steps: 1. Use the Increment/Decrement buttons to select Function 02, and press Enter. 2. Use the Increment/Decrement buttons to select the IPL type and mode you want, and then press the Enter button to save. 3. Optional: To specify a fast or slow IPL that can only be set one time at the console panel when the system is turned off, follow these steps: a. Select Function 02 and press Enter twice. b. Use the Increment/Decrement buttons to select F (Fast), S (Slow), or V (Value from IPL attributes). The Hardware diagnostics IPL attribute determines the type of subsequent IPLs. *MIN is the preferred setting. However, if you anticipate any hardware problems, specify *ALL on the Hardware diagnostics parameter. Use the Change IPL Attributes (CHGIPLA) command to change the IPL attribute. Related tasks Restarting and powering down a system with logical partitions IPL type: The IPL type determines which copy of programs your system uses during the initial program load (IPL). There are four IPL types:
44
IPL type A Use IPL type A when directed for special work, such as applying fixes (PTFs) and diagnostic work. For example, use IPL type A in the following circumstances: v When IPL type B fails v When the procedures direct you to use IPL type A v When you suspect problems with temporary Licensed Internal Code fixes. IPL type A uses the A copy of Licensed Internal Code during and after the IPL. This copy of Licensed Internal Code is the permanent copy. It resides in System Storage Area A. It contains no temporarily applied fixes. IPL type B Use IPL type B for routine work and when directed by a PTF procedure. This type of IPL runs the newest copy of Licensed Internal Code and is necessary when you permanently apply certain fixes. IPL type B uses the B copy of Licensed Internal Code during and after the IPL. This copy resides in System Storage Area B. This copy contains temporarily applied fixes. IPL type C Rochester development support reserves this type of IPL for hardware service representatives. Attention: Do not use this function. Data loss can occur with improper use of this function.
IPL type D Use IPL type D when directed for special work, such as installing and reloading programs. IPL type D loads the system programs from an alternate IPL load source, such as a tape drive or CD-ROM. Typically an IPL uses programs that are stored on the primary IPL load source (typically a disk drive). Sometimes it is necessary to perform an IPL from another source, such as programs that are stored on tape. To do this, you must use IPL type D to perform an IPL from the alternate IPL load source. Use IPL type D only during one of the following situations: v When the installation or restore procedures direct you to use IPL type D v When IPL type B and IPL type A fail (when the primary IPL load source cannot perform an IPL on the system properly) and only when directed by your support personnel v When service directs you to perform an alternate installation Related concepts Changing operating modes and IPL types on page 46 By changing IPL types, you can perform an initial program load (IPL) from the load-source media or from an alternate load source media. With this operation, you can apply fixes (PTFs). By changing the operating mode, you have several options in controlling the IPL. Related tasks Using software fixes Operating mode of an IPL: The operating mode determines the number of options that are presented to the operator for consideration during and after the initial program load (IPL). It can also secure (lock) the control panel to prevent an unauthorized or inadvertent IPL from the control panel. There are four operating modes:
45
Normal (unattended) After the power-on, operating the system in Normal (unattended) mode requires no operator intervention during the IPL. When you turn on the system in normal mode, it performs the IPL and presents the Sign On display on all available display stations. The operator cannot change the system during the IPL. Dedicated service tools (DST) and the operating system do not present any displays during this IPL. Use a normal mode (unattended) IPL to perform the following actions: v Perform an IPL and run the system for most routine work v Perform a remote IPL v Turn on and perform an IPL by date and time Manual (attended) After power-on, operating the system in Manual (attended) mode means that an operator uses the control panel to direct the system for special needs. During manual mode IPL, DST and the operating system present menus and prompts that allow you to make changes to the internal system environment. This can include entering debug mode for service representatives to diagnose difficult problems. Use the manual mode to perform an IPL and run the system to perform the following actions: v Change IPL options (including system values) v Install the operating system v Load fixes (PTFs) v Make some types of system hardware upgrades v Use DST (for advanced users and service only) v Problem diagnosis (for advanced users and service only) Auto (automatic) Use Auto mode for an automatic remote IPL, automatic IPL by date and time, and an automatic IPL after a power failure. Secure Use Secure mode to prevent use of the control panel to perform an IPL. This mode is not a form of IPL; it is a means to prevent an unauthorized or inadvertent IPL from the control panel.

Changing the IPL startup program

A startup program changes the system resources that are started during an initial program load (IPL). The program also changes the resources and attributes assigned to the system resources that are started during an IPL. Typically, subsystems, writers, and Operational Assistant are launched by this program. The autostart job in the controlling subsystem transfers control to the program that is specified in the startup program to set the QSTRUPPGM system value. You can tailor this program. You can create your own program and change the Startup program to set up the QSTRUPPGM system value to that program name. Or, you can use the program QSTRUP in the QSYS library as a base to create your own program. To do this, follow these steps: 1. Use the Retrieve CL Source (RTVCLSRC) command to retrieve the source of the program, for example, RTVCLSRC PGM(QSYS/QSTRUP) SRCFILE(YOURLIB/YOURFILE)). 2. Change the program. 3. Use the Create Control Language Program (CRTCLPGM) command to create the program, and then save it to your own library. 4. Test the program to ensure that it works. 5. Change the Startup program to set up the QSTRUPPGM system value to the program name and library you specified on the CRTCLPGM command.

Startup program to set the (QSTRUPPGM) system value: The program to set the QSTRUPPGM system value is the startup program. The QSTRUPPGM system value specifies the name of the program that is called from an autostart job when the controlling subsystem is started. This program performs setup functions, such as starting subsystems and printers. This system value can only be changed by the security officer or by someone with security officer authority. A change to this system value takes effect the next time an initial program load (IPL) is performed.
49
The QSTRUPPGM system value can have these values: v QSTRUP QSYS: The program that is specified is run as a result of a transfer of control to it from the autostart job in the controlling subsystem. v *NONE: The autostart job ends normally without calling a program. The default startup program QSTRUP in library QSYS performs the following actions: v Starts the QSPL subsystem for spooled work v Starts the QSERVER subsystem for file server work v Starts the QUSRWRK subsystem for user work v Releases the QS36MRT and QS36EVOKE job queues if they were held (these are used by the System/36 environment) v Starts Operational Assistant cleanup, if allowed v Starts all printer writers unless user specified not to on the IPL Options display v If the controlling subsystem is QCTL, it starts the QINTER, QBATCH, and QCMN subsystems

Scheduling a system shutdown and restart

You can set up a schedule that automatically turns your system on and off at the time of day you set. You can also specify special circumstances that change the normal daily schedule, such as a holiday or special closing. For some systems, you might want to regularly schedule routine shutdowns and startups. The operating system supports this function by allowing you to define a schedule that alerts users to an upcoming shutdown, and then waits a predefined amount of time to allow users to finish their work and sign off. For example, you can define a schedule that must shut down your system Friday night and start it again Monday morning. The schedule also allows you to define a message that is sent to any signed-on users, and to specify how long to wait between sending the message and beginning the shutdown sequence. To work with a schedule, type go power on any command line. Related concepts Starting the system without making configuration changes (unattended IPL) on page 39 This is the most common way to start the system. Unattended initial program loads (IPLs) reset system storage and recognize any configuration changes automatically. Related tasks Stopping the system on page 55 Turning off your system needs careful attention. If you turn off the system without following this topic, data might be damaged, or the system might behave in unpredictable ways. Displaying the power-on and power-off schedule: The power-on and power-off schedule ensures that the system is turned on and off at specific times during the day or night. You can view this schedule. To view this schedule, follow these steps: 1. On any command line, type go power and press Enter. 2. Select option 1 (Display power-on and power-off schedule) on the Power On and Off Tasks menu.
50
The power-on and power-off schedule shows the date, day, and time (using the 24-hour clock) that the system will be turned on and off. The Description column includes comments about those days that have been changed from the system's regular schedule. Any user can display this schedule. Changing power-on and power-off schedule defaults: You can change the current settings for your schedule. To set up your own power-on and power-off schedule, select option 2 (Change power on and power off schedule) on the Power On and Off Tasks (POWER) menu. On the Change Power On/Off Schedule display, press F10 (Change power on/off defaults). On this display, you can change the first day of the week by typing a number in the First day of week field. Also, the system automatically sends users a message telling them when the system will be turned off. In the Minutes before turning off to send field, you can indicate the number of minutes before turning off that you want the system to send this message. When the system sends the power off message, you can delay the scheduled time for turning off from 30 minutes to 3 hours when you reply to the message. Then the system will wait the time specified before turning off. You do not have another chance to delay the time. For example, if you want the system turned on at 7:30 a.m. and off at 8:00 p.m. on Saturdays and Sundays, type the new times in the Default Power On and Default Power Off columns next to Saturday and Sunday. When you press Enter, your changes are shown on the Display Power On/Off Schedule and the Change Power On/Off Schedule displays. Changing the power-on and power-off schedule for a single event: You can create a one-time scheduled shutdown and startup, without adjusting the default schedule. Use the Change Power On/Off Schedule display to change the power-on and power-off schedule for a single day. For example, to change the startup and shutdown time for the company picnic on Wednesday, May 3, follow these steps: 1. Type 14:30 in the Power Off column to turn the system off at 02:30 p.m. so the employees can attend the picnic. 2. Type the reason for the change, Closing - Company picnic, in the Description column across from the date and time and press Enter. 3. Type the start time 05:30 in the Power On column to turn the system back on Thursday, May 4. To display the schedule starting on a different date, type the date you want to start with in the Start list at field and press Enter. The information that is displayed begins with the date you specify. Solving problems with the automatic power schedule: If the power schedule is not working, use this topic for diagnosis. v Make sure that the Start Cleanup (STRCLNUP) command is part of your startup program. v The automatic power scheduler uses a job called QSYSSCD to process the requests for schedule changes. The Start Cleanup (STRCLNUP) command must be run to start the QSYSSCD job. The IBM-supplied startup program includes the Start Cleanup (STRCLNUP) command. If you have your own startup program from a previous release, it might not contain the Start Cleanup (STRCLNUP) command. v Make sure that you specify Yes on the Change Cleanup (CHGCLNUP) command to allow automatic cleanup. The QSYSSCD job will not start if you do not allow automatic cleanup.
51
v Make sure that the Start Cleanup (STRCLNUP) command submits the QSYSSCD job to the job queue specified in the Change Cleanup (CHGCLNUP) command. v Check to see if the QSYSSCD job is running; it could be on a held job queue. v Make sure that the job queue to which the Start Cleanup (STRCLNUP) command is submitted has the Maximum jobs parameter set to *NOMAX or a number greater than 1. Because the QSYSSCD job always runs, the other jobs that perform automatic cleanup and turn-off functions are not able to start if the Maximum jobs parameter is set to 1. To change the Maximum jobs parameter on the job queue entry, use the Change Job Queue Entry (CHGJOBQE) command. v Make sure that the mode is set to Normal or Auto. Related concepts Operating mode of an IPL on page 45 The operating mode determines the number of options that are presented to the operator for consideration during and after the initial program load (IPL). It can also secure (lock) the control panel to prevent an unauthorized or inadvertent IPL from the control panel.
Causes of abnormal IPLs

These situations can cause an abnormal initial program load (IPL). v Using the End Job Abnormal (ENDJOBABN) command. To see if this command has been used, look for message CPC1124 in the job log. v Using option 7 (Start a service tool) and then option 7 (Operator panel function) on the Dedicated Service Tool (DST) menu. v Using the Power button (on the control panel) instead of the Power Down System (PWRDWNSYS) command. v Displaying a power failure before all data is written from main storage to disk. v Using any B900 xxxx system reference code (where xxxx is any number or letter) during the start of the operating system phase of the IPL. v Ending with a system reference code of B900 3F10, if the PWRDWNSYS command did not complete processing. v Causing the system to end by any function check in the controlling subsystem. v Issuing a PWRDWNSYS command in the primary partition without first powering down secondary partitions. v The system going down when database recovery has not completed during the IPL. Note: If the ENDJOBABN command is issued, message CPI0990 will be in QHST. For all other reasons, message CPI091D will be in QHST stating why the IPL is abnormal.

Signing on to the system

The i5/OS operating system requires users to sign on to the system before they gain access to any system functions. This provides an important measure of security and allows for each user's session to be customized. In addition to checking the password, the operating system uses the sign-on operation to access the specified user profile. The operating system uses this profile to customize the displays, providing consideration for the user's language and available functions.
Signing on to the system using System i Navigator

You can sign on to the system from System i Navigator. Then you can access functions on the system. To sign on to the system from System i Navigator, follow these steps:
52
1. Select a system. 2. At the System i Signon prompt, enter your user ID and password.
Signing on to the system using the character-based interface

You can sign on to the system from the character-based interface. Then you can obtain access to system functions. To sign on to the system using the character-based interface, follow these steps: 1. Type your user ID and password and fill in any of the optional entry fields you want to use. Use the Tab key to move the cursor from field to field on the display. Notes: v The Password field is displayed only if password security is active on the system. v The top right corner of the Sign On displays the name of the system you are using, the subsystem the system is using, and the display station identifier (ID). 2. Press Enter. If this is an unattended IPL, one or more of the following displays is shown, depending on what options you select on this display or what is defined in your user profile: v The Main Menu is displayed. v Another menu is displayed. v A program or procedure is run. v A current library is inserted into your library list. If you specify a program or procedure to run and a menu to be displayed, the program or procedure is run first and then the menu is shown. After signing on, you can change your system password. Now that your system is up and running, be aware of the following aspects: v The Operational Assistant displays are now the default. v The system cleanup functions are automatically started with default values. v The Attention key program displays the Operational Assistant (ASSIST) menu (the default).
Changing your password

During the installation of the i5/OS licensed program, you might need to enter the system password for the initial program load (IPL) to continue. When you install the i5/OS licensed program, the licensed program runs a check to detect system model changes, certain service conditions, and ownership changes. If the licensed program detects these changes or conditions, you are prompted to enter the system password before IPL can continue. If no changes or conditions are recognized, the IPL continues without a request for the system password. You must enter the correct system password to complete the IPL. If the system password is not available, you or your service representative can temporarily bypass entering the system password for a limited time. When the bypass period starts, immediately contact your marketing representative, who will have IBM send you the correct system password. To order the system password, ask your marketing representative to order nonstandard RPQ S40345 if you are in the United States, Asia-Pacific, Canada, Latin America, or Japan. If you are in Europe, Middle East, or Asia, request nonstandard RPQ S40346.

Messages
Messages are communications sent from another user, from the operating system, or from an application. Messages are communications that are sent from a person, a program, or the operating system to a message queue. Every user profile and workstation has a message queue associated with it. All message queues are named after the user or workstation that they are associated with, and get created automatically when the user signs on to the system for the first time, or when the workstation is first defined. The message queue for the QSYSOPR profile is particularly important because the system sends many messages about job completion and system status to the QSYSOPR message queue.
Working with messages

You can use System i Navigator to display, reply to, and send messages. To work with messages, expand Basic Operations, and click Messages. System i Navigator displays all the messages for either your message queue, or a specified message queue. To reply to, delete, or view the properties for a specific message, right-click the message and select the required action. To send a message, right-click Messages in System i Navigator, and click Send a message. Also, your system administrator can set up a message monitor in System i Navigator to watch for and handle messages. Related concepts Details: Message queues Scenario: Message monitor
i5/OS commands
The operating system uses control language (CL) commands to interpret instructions from users. You need to know the basic rules for using CL, and how to get detailed help for any CL command. CL provides a powerful and flexible means of entering commands on the system. You can use CL to control most of the operating system functions by entering them from the character-based interface, by including them in programs, or by sending commands in System i Navigator. While the System i menu system and CL commands might be unfamiliar at first, they follow an easy-to-use syntax, and the operating system includes many features to help you use them successfully.
61
CL command syntax
CL commands consist of a verb, an object, and sometimes an adjective; for example, WRKACTJOB:
Verb WRK Work Adjective ACT Active Object JOB Job
One of the important features of CL syntax is that it is consistent. For example, regardless of the object or command you want to work with, using the verb WRK in the command starts a menu that allows you to perform the available actions on the specified object.
Entering CL commands
You can enter CL commands from System i Navigator by selecting Run a command from the taskpad. In System i Navigator, a taskpad is a view of system tasks that lets a user interact with operating system functions. It contains a set of interrelated tasks that either perform a function or launch help that explains how to perform a function. Alternatively, you can enter CL commands from any command line and most displays on the character-based interface. Every command has a set of required and optional parameters. For example, Create Library (CRTLIB) requires, at a minimum, that you specify the name of the library that you want to create. The syntax for more complex CL commands is command_name parameter (value). For example, CRTLIB LIB (FRED) enters the verb create on the object type library, and specifies that the required parameter LIB, the library name, must have the value FRED. This command causes the operating system to create a library called FRED. If you are not familiar with the parameters associated with a CL command, you can enter the command with the parameters you already know, place the cursor on the command, and press F4 (Prompt). The system then displays the available options for the command. Entering a command without any parameters also causes the system to prompt you for any required fields, making field-level help available. For example, entering CRTLIB causes the system to show the following display.
Entering a ? in any field brings up detailed help for that parameter.
62
Getting help with CL commands

The operating system provides several methods for helping users access and enter CL commands. The Command Entry program provides a useful interface and additional help. You can start this program by entering CALL QCMD from a command line. The CL finder in the information center can also help you find a specific command. Most importantly, remember that entering a command without any parameters, or pressing F4 (Prompt) while your cursor is over the command, displays a menu with detailed help for all associated parameters. Related concepts Using system interfaces on page 2 Depending on the type of connection to the system and the task you need to perform, several options are available for system interfaces. You can access and use your system by the System i Navigator interface, by the character-based interface, and by wireless clients.

Security and user authority

The operating system determines which resources users might access based on information in their user profiles and the security strategy implemented for this system. Security is a critical part of system operations. It is built into the operating system, and impacts nearly every function on the system. The System i security environment determines the commands and functions available to users, and the objects they can access. Typically the security strategy restricts the objects a user can access. For systems with object-level security, there are several ways to provide authority to access objects. Often, user profiles will explicitly grant types of access to specific objects. To simplify the task of managing all these permissions, authorization lists can specify groups of objects, and users can be given access to these lists. Accessing these lists then provides access to all of the objects the list specifies. The level of system security and other more detailed security practices often affect system operations. The following concepts are important for understanding user requirements in various security environments.
Security levels The operating system operates in one of several predefined levels of security. The security level currently in effect determines the level of detail that user profiles must provide to grant appropriate access to system resources. This level of detail can range from simple password management to explicitly providing a level of access to each object that a user can read or change. Many more detailed aspects of system security are set by the system values. These system values set the security level, and grant or restrict options like adopted authority. The user profile contains most of the authorizations and preferences for individual users or groups. You can use System i Navigator to create and manage users and groups across the system. You can create authorization lists that specify groups of objects. Users and groups can then be authorized to this list, granting them authority to everything that list contains.
Security system values User profiles Authorization lists
Also, security settings regarding policies and authorization lists are available in System i Navigator under Security.
63
Related concepts System values
Authority to access objects

Depending on the security level and other security settings, users might be given several levels of access to objects on the system.
Table 13. Levels of accessing authority Access All object Object Object data public Description Grants unrestricted access to every object on the system. Grants access to specified objects. Grants access to the data contained in specified objects. Grants default access to public objects
Assume that a user needs authorization to add, change and delete data in a database, but does not need to delete tables or the database itself. The user can be granted object data-level authority, rather than object-level authority. Note: Adopted authority will grant users access to objects called by an object they are working with. Administrators can allow or restrict adopted authority with security system values.
Security levels
The operating system operates in one of several predefined levels of security. The security level currently in effect determines the level of detail that user profiles must provide to grant appropriate access to system resources. This level of detail can range from simple password management to explicitly providing a level of access to each object that a user can read or change. Security on your system is arranged in a series of levels or classes, each offering a greater degree of security and protection of your data than the previous. Select the level that best meets the needs of your organization. You can use System i Navigator to change these settings on a single system or across multiple systems. Level 20 This level is referred to as password security. That is, users must have a password and user ID that is recognized by your system to gain access to the system. Both the user ID and initial password are created for users by the system administrator. This level of security offers all users on the system total authority to do anything they want. That means they can access all data, files, objects, and so on, on your system. This might be appropriate for small businesses where internal security is a low priority, but will likely be inappropriate for larger businesses that do not want every employee to be able to access confidential payroll files, for example. Level 30 This level is referred to as resource security. That is, users must have a valid user ID and password defined for them by the system administrator, and no longer have automatic access to everything on the system. User access is limited by the security policies of the business. Level 40 This level is referred to as system integrity security. That is, at this level, the system itself is protected against users. User-written programs cannot directly access the internal control blocks through pointer manipulation. Level 40 is the default security level for every new installation.
64
Level 50 This level is referred to as enhanced system integrity security. Level 50 is the recommended level of security for most businesses, because it offers the highest level of security currently possible. Not only is the system protected against user-written programs, but it ensures that users only have access to data on the system, rather than information about the system itself. This offers greater security against anyone attempting to learn about your system. Related information Planning and setting up system security Security reference
User profiles
The user profile contains most of the authorizations and preferences for individual users or groups. With System i Navigator, you can create and manage users and groups across the system. User profiles contain the information that the system requires to allow users to sign on to a system, to access their own customized session, including their own message and output queue, and to access functions and objects to which they have been granted authority. A user profile includes: v A system user profile name v The user's privileges and limitations v A list of objects the user owns or is authorized to use v A reference to a message queue v A reference to an output queue v Information about which groups the user is a member of (up to 16) v v v v Information about the user's last sign-on Job attributes, such as description and priority, the initial program to call, and the initial library list National language settings Other attributes, such as the user ID (UID), group ID (GID), and home directory
User profiles can be included in group profiles. In this way, all group members share attributes, access to specific objects, and ownership of objects. Group profiles can simplify many user administration tasks by allowing you to apply a single change to many users. System i Navigator's user administration function provides convenient ways to manage users and groups across the system.
Working with user profiles

Use System i Navigator to create and manage user profiles and groups if your own user profile has the required authority. Expand Users and groups to create and manage user profiles. Additionally, you can use this function to perform some common actions on a selected user, such as sending a message, and working with that user's jobs and objects. Related concepts Managing users and groups with Management Central
Authorization lists
Authorization lists consist of a list of users or groups, the type of authority (use, change, and exclude) for each user or group, and a list of objects to which this list provides access. Providing each user with explicit access to every object the user needs to work with might create a great deal of duplicated effort because many users need to access the same group of objects. A much easier
65
way to provide this access is to create authorization lists. Users and groups can then be authorized to this list, which grants them authority to everything that the list contains. To work with authorization lists, open Security in System i Navigator and select Authorization lists. For example, an authorization list can be created to contain a list of objects related to an inventory database. A user responsible for ordering new inventory items can be granted authority to see the contents of the database objects. Additionally, a user group in shipping and receiving needs to update this database as parts come in and out of stock. This group can have authority to change the contents of the objects.
Files and file systems

Files and file systems present information about database file management, spooled files, tape files, and the integrated file system capabilities of the IBM System i platform.
Integrated file system

Files in the operating system are significantly different from their counterparts in the UNIX and Windows operating systems. In the operating system, a file is another kind of object on your system. Each file has a description that describes its characteristics and how the data associated with the file is organized. Whenever the operating system processes a file, it uses this description. In addition to differences in handling files, the operating system also uses unique structures to store the files and other objects on the system. However, the integrated file system in System i Navigator might look familiar to people who are used to a hierarchy based on the Windows operating system. UNIX users might recognize some elements of this hierarchy, as well as the presence of file pointers. You can access the integrated file system in System i Navigator. With the integrated file system, you can find, change, and copy files and libraries on your system by navigating through a hierarchy that is similar to Windows Explorer. You can use the integrated file system to copy data files onto your client PC.
Database file management

Learn about traditional file management functions that your application uses in creating and accessing data on the system and in ensuring the integrity of the data. File management is the part of the operating system that controls the storing and accessing of traditional file objects (*FILE objects in the QSYS.LIB library) on the system.
Spooled files
Spooling is a system function that saves data in a database file for later processing or printing. With spooled files, you can manage your data files on attached devices, such as a diskette or printer.
Tape files
Tape files are device files that provide access to attached tape devices. The Tape files topic collection describes the characteristics and use of tape device files for application programs. This topic also provides information about storing and accessing data from a tape device, and conceptual information about tape, tape data files, and tape device files.

i5/OS restricted state

At times, it is necessary to place the operating system in restricted state. This is a concept unique to the operating system and must only be performed when necessary. Restricted state is a condition that occurs when all subsystems are ended, either manually or automatically by the system. When the operating system is in restricted state, most jobs cannot be active, and users cannot connect to the system. You need to ensure that information is saved and that other systems, such as a Windows server, are properly powered down before putting the operating system in restricted state. If not, there is a high risk that you will lose data. The following examples show the most common tasks that require or highly recommend restricted state status: Performing a full system backup When a full system backup is performed, the operating system is automatically placed in restricted state. Restricted status is required because the system requires sole access to everything it is backing up. Saving multiple items You should put the operating system in a restricted state when backing up multiple items, such as libraries, documents, directories, and storage. As was previously stated, the system requires sole access to each object it is backing up. If the system is not in restricted state and someone is using a library when the system tries to back it up, the save operation will not complete successfully. Software installation and upgrade At various points during a software installation or upgrade, the operating system is required to be in a restricted state. During these procedures, you are given instructions on how to do this. There are many more situations where certain tasks require that you perform this operation. The individual tasks will include specific requirements and instructions. When required, you can place the operating system in restricted state by entering the following command at a command line, type ENDSBS SBS(*ALL) OPTION(*CNTRLD) DELAY(600) and press Enter. Notes: v For the Delay parameter, specify a number of seconds that allows your system time to bring most jobs to a normal end. On a large, busy system, you might need a longer delay. For more information, use the online command help. v The End System command (ENDSYS) will also put the system into restricted state. The system sends messages to the QSYSOPR message queue. These messages indicate that the subsystems ended, and that the system is in the restricted state.
67
Jobs
All work done by the operating system is divided into units called jobs. Jobs are how the operating system organizes, tracks, and processes work. A job typically includes all of the information the system requires to complete a specific task. This information might include data files, programs, and instructions for processing and tracking the job throughout its processing. Jobs vary greatly in their complexity, ranging from simple tasks, like printing a specified document, to complex procedures, like generating reports based on information spread throughout the system. Tracking and managing jobs is an important part of normal system operation. Jobs are an essential part of work management. To learn more about how jobs are processed, including working with subsystems and job queues, see The structure of your system. For an example of how jobs move through the system, see A job's life.
Working with jobs

You can work with jobs in System i Navigator. Jobs in the Basic Operations folder displays all the jobs associated with the current user. To display other jobs, right-click the Jobs folder, and select Customize this view Include. The Server Jobs - Include window allows you to limit the list of server jobs displayed in the System i Navigator window to those that meet the criteria you specify. Alternately, you can see the jobs submitted by the system by clicking Work Management Server jobs, or view the jobs currently being processed by clicking Work Management Active jobs. The following display shows the jobs in System i Navigator.
68
Figure 3. Job display in System i Navigator
After finding the jobs you want to work with, you can display their attributes or change their queue, priority, messages, and other features by right-clicking the job and clicking Properties. Additionally, your system administrator might decide to set up a job monitor to work with some jobs. Related concepts Managing jobs Related tasks Creating a new monitor
Subsystems, job queues, and memory pools

You can control work on the system by working with the resources used to process jobs. Subsystems, job queues, and memory pools are the basic parts of work management. You can work with subsystems and job queues to manage specific jobs or to adjust the system's work flow. To efficiently use system resources, different types of jobs require different processing instructions and system resources. To meet this need, the operating system creates unique operating environments called subsystems. Each subsystem has a set of system resources, especially a memory pool, that determines how quickly it can process jobs. Subsystems also have unique processing instructions and, in many cases, at least one associated job queue. The job queues hold incoming jobs from the users or applications until an associated subsystem has available resources. The job then moves from its queue into the subsystem where it is processed based on the instructions and resources available to that subsystem. Finally, any output that results from job processing gets handled and routed by the instructions in the job description.
69
During this process, you might want to monitor a job's progress or adjust its priority. Also, if the system is having trouble processing certain types of jobs, you might need to adjust the subsystems resources.
Working with subsystems, job queues and memory pools

With System i Navigator, you can view subsystem properties, view job queues that are in use by an active subsystem, start and stop a subsystem, and adjust memory pools. These functions are available under Work Management in System i Navigator. However, some subsystem commands are only available from the character-based interface. Related concepts The structure of your system A job's life Subsystems Memory pools Managing subsystems Managing memory pools Related tasks Stopping the system on page 55 Turning off your system needs careful attention. If you turn off the system without following this topic, data might be damaged, or the system might behave in unpredictable ways.
Objects
Everything on the system that can be worked with is considered an object. Objects provide a common interface for working with system components. This topic discusses the different kinds of objects and how to work with them. One of the differences between the i5/OS operating system and other operating systems is the concept of objects. Anything that you can change in the operating system is a type of object. For example, data files, programs, libraries, queues, user profiles, and device descriptions are all types of objects. By treating everything as an object, the operating system can provide all of these items with an interface that defines what actions users can perform, and how the operating system needs to treat the encapsulated data. Additionally, this interface allows for standardized commands across different system elements; the commands for working with user profiles and data files are similar. One important type of object is the library. Libraries are essentially containers, or organizational structures for other objects, and you can use libraries to reference other objects on your system. Libraries can contain many objects, and can be associated with a specific user profile or application. The only library that can contain other libraries is called QSYS. It contains all other libraries on the system. There are many different types of objects in the operating system. Finding objects and performing actions on them are basic functions of system operations.

Logs and journals

Protecting the data and system resources is a critical part of the operating system. One important way that the i5/OS operating system accomplishes that goal is to keep detailed records of any changes to system resources. These records, called logs or journals, can help solve system problems or recover damaged data.
Logs
A log is a database file that contains the history of backup, archive, recovery, and media management operations that can be displayed online or printed for future reference. Logs are used in backup and recovery situations. Logs can also contain information about jobs, general system information, and problems.
Table 14. Types of logs Log Job logs History logs Problem logs Description Track the description, status, and action of jobs performed by the system. Get general system information, like device changes, operator messages, job completion and other activities. Retrieve records of system problems that occurred on a system.
Journals
A journal is a system object that contains information about changes made to another system object. The journal can be used to recover database files, data areas, data queues, and integrated file systems objects. Regular journaling speeds up management tasks such as save operations. Related concepts Job logs History logs Problem logs Journal management Related information Recovering your system PDF
Software fixes
You can use fixes to install and manage software and software updates. IBM supports several different releases of the operating system, and businesses might have several systems running different versions. This can cause some system operations to be more complex; different versions of the operating system can contain new or changed functions and features. Moreover, IBM provides updates to the operating system and other programs between releases in sets of program
71
temporary fixes (PTFs), also known as fixes. The PTFs that have been applied to a system can also affect system operations. System i Navigator provides ways to manage the software and fixes across a business. Related concepts Maintaining and managing i5/OS and related software PTF Maintenance Strategy
Printing the system configuration list

The system configuration list is a printed record of your system contents. You need to know your system configuration when you plan to install or change any hardware or software and when you recover from a disaster or evaluate the results of a major system change. Note: For partitioned systems, you must print the system configuration list from each partition. The system configuration list shows only the hardware resources that are assigned to that partition. To have a complete view of the system configuration of the entire system, you must obtain the printout from every partition. It is preferred that each time you make configuration changes to a partition, you obtain the latest system configuration list of the partition afterwards. If you are printing a configuration list from your primary partition or secondary partition, see Printing system configuration for logical partitions. You must configure Service Tools user IDs before starting SST. For more information about how to configure a user ID, see Managing service tools user IDs using DST and SST. Your user ID must have Hardware Service Manager authority. To print the system configuration list, follow these steps: 1. Start System Service Tools (SST). On any command line, type STRSST (Start System Service Tools) and press Enter. 2. Sign on to SST with your user ID. 3. Select option 1 (Start a service tool). 4. Select option 7 (Hardware Service Manager). 5. Use the Print function key (F6) on the Hardware Service Manager display to request a printout. The Print Format Options display appears. You can sort the information by location or by logical address. Notes: v The logical address sort and location sort are available only in 132-character width. v The logical hardware and the packaging hardware have unique resource names. To collect more details about the system configuration list, you can select the Print function key from a display other than the Hardware Service Manager display, but the system prints only the information that appears on the display. To display or print details that include descriptions about the system bus, main storage, or processor, follow these steps: a. Select the Logical Hardware Resources option. b. On the Logical Hardware Resources display, select one of the following options to display details: v System bus resources v Processor resources v Main storage resources Your system configuration list prints on the printer that you specified.
72
The printout consists of the following sections: v System information, which includes the system type, model, serial number, and release. v Packaging hardware resource information, which includes the resource name, type and model, serial number, part number, frame ID, card position, and device position. v Logical hardware resource information, which includes the resource name, type and model, serial number, and logical address. v A legend, which includes the descriptions of the indicators and logical address format information. Use the legend to help you interpret the information.
Analyzing and reporting system problems

System problems are carefully tracked and managed in the operating system. When the system detects a problem, it generates a problem record and sends a message to the system operator message queue (QSYSOPR). Familiarity with this process and the ability to perform basic troubleshooting and problem handling procedures are a basic part of system operations.
