Description

[Detailed Description of the Invention] [Industrial Application Field] When configuring a composite computer system consisting of a plurality of computer systems, the present invention is designed to ensure that the system generation of the individual computer systems is consistent with each other. The present invention relates to a batch generation method that can be performed all at once.

[Conventional technology]

Creating a new system by selecting system functions according to the user's requirements for the system and the user's equipment configuration is called system generation. The volume that stores the operating system for controlling this new system is the system resident volume.

IPL (Initial) from this system resident volume.
By performing the program load), the operating system is loaded into the main memory of the computer system, and various programs (online programs and batch programs) can be executed. Therefore, generating a new operating system on this system-resident volume is system generation.

As a conventional system generation method, for example,
Hitachi Program Product VO33/ES
System Generation J Manual (+989),
pp. 1-5. According to this, in system generation, in order to specify the functions to be incorporated into a new system and the input/output devices of the system,
A series of macro instructions called system generation macro instructions are used.

The order of creating a system is (1) designing a new system;
(u) Estimating memory requirements, determining system data sets, and estimating capacity; (m) Determining the allocation medium for system data sets; (1v) Specifying system generation macros; (V) System generation (vl) Execution of stage 1, (■) Execution of stage 2, (vffi) Testing of the new system. the above(
In step 1), in order to create a system that is optimal for the operation mode of the computer center, the optimal function is selected from the various optional functions possessed. In (■) above, determine the memory requirements and system data set by referring to the information described in the system data set in the manual, and if the capacity calculation results in a negative impact on the system processing capacity, redesign the system again. fix. In (1) above, the purpose and frequency of use are considered for each system data set, and the medium to which the data set is assigned is determined. In (iv) above, each system generation macro described in the manual and the operand of the macro are specified, and input parameters for system generation are created. In (V,) above, in order to create an optimal system, a starter operating system (O8) and a master tape are given,
Use these to set the system generation environment. That is, a master disk is created in which the contents of the driving O8 that controls system generation and the master tape are transferred. In the above (vi), the system generation tuna and a parameter group specifying its macro operand are assembled as one job under the control of the driving O8. In (■) above, (
A system resident volume is created using the job stream and master disk outputted in the 7-semblage section vi) as input. In the above (vffi), a program is used to test whether the created new system operates as designed.

As mentioned above, in conventional system generation, 1
Only a system resident volume for one computer system can be created in one generation.

In the case of a compound computer system, it is desirable to create a plurality of computer systems constituting the system in one generation, but this has not been possible in the past. Therefore, in the case of a complex computer system, either (a) system generation is executed for the number of computer systems that make up the system, or (b) system generation is executed only for one computer system. Then, copy the system resident volume created by this for the number of computer systems that make up the complex computer system, and change only the information necessary to change the volume serial number of the system data set recorded in the volume. and created individual contents.

However, in method (a) above, conflicts between the system generation specifications recorded on the system resident volume created for each computer system constituting the compound computer system, such as the specifications for shared disks, can occur. There is a latent possibility that contradictions, etc. will occur, which will hinder the operation of the system and increase the amount of man-hours and time required for generation. In addition, with method (b) above, in cases where the tasks to be executed are different for each computer system that makes up a compound computer system, it is not possible to simply copy from the resident volume using the same system generation. However, it is not possible to create a system resident volume for each computer system.

[Problem to be Solved by the Invention 1] As the scale of computer systems is required to be expanded, business operations are often carried out using complex computer systems composed of a plurality of computer systems.

However, in a compound computer system, the cost required for operation tends to increase in proportion to the number of computer systems. The reason for this is that if there is a conflict between the commands for each computer system that makes up the compound computer system, the operation will be hindered. For example, if a command for a magnetic disk shared by two computer systems is inconsistent between the two systems, the system will malfunction. Further, even when there is no contradiction, if different instructions are created for each computer system, there is a problem that the number of instructions increases in proportion to the number of computer systems.

Furthermore, during system generation for system generation on the resident volume of each computer system that constitutes a compound computer, if there is a conflict in the specification of system generation parameters for each computer system, the compound computer system will malfunction. will come. As the number of computer systems configuring a compound computer system increases, a problem arises in that the number of system generation parameters specified as a whole increases.

The first object of the present invention is to solve these conventional problems and to provide instructions to each computer system in system generation for generating a system on the system resident volume of each computer system constituting a complex computer system. It is an object of the present invention to provide a method and apparatus for batch generation of a complex computer system, which can prevent malfunctions in the generation of the complex system by preventing conflicts between them.

Further, a second object of the present invention is to provide a system for generating a multi-computer system at once, which can reduce the number of parameters specified in system generation in system generation for generating a system on the system-resident volume. The purpose of this invention is to provide a generation method.

[Means for Solving the Problems 1] In order to achieve the above object, the batch generation method of a compound computer system according to the present invention can be specified as follows: (a) It is possible to uniquely specify each computer system constituting each computer system. By providing a system-specific generation parameter and a system-common generation parameter common to each computer system, and processing the system-common generation parameter and system-specific generation parameter separately, a complex computer system can be created. It is characterized by the ability to collectively execute the generation of multiple computer systems that make up the system. Another feature is that (b) it includes the step of assigning a unique name to a set of some or all of the system-specific generation parameters.

[Function] In the present invention, when performing system generation to collectively create system resident volumes for each computer system constituting a compound computer system, the system generation program creates a system common generation volume. By inputting the generation parameters and the system-specific generation parameters, the system generation parameters for each computer system making up the complex computer system are reconstructed from these two parameters. For each reconfigured computer system, a system resident volume for each computer system is generated from the system generation parameters. This prevents mutual contradiction between systems and prevents system generation from malfunctioning.

Furthermore, the unique name (this is called a set name) given to some or all of the system-specific generation parameters for one computer system that constitutes a complex computer system is the unique generation parameter for other computer systems. If specified as a parameter, the system generation program recognizes the system-specific generation parameters for which the set name is defined from this set name, and creates the generation parameter group corresponding to this set name. Quote. This makes it possible to reduce the number of parameters specified in system generation and eliminate duplicate names.

In FIG. 1, 101 is a central processing unit that executes batch generation, 106 is a starter system resident volume that stores driving 03105, and 107 is a system resident volume that stores target O8. The central processing unit 101 is provided with an instruction execution processor 102 for executing program instructions, and a main memory 103 that can be referenced and updated by the instruction execution processor 102. The main storage device 103 stores a system generation program 104 for realizing the complex computer system-integrated system generation of the present invention, and a new O8 program.

That is, the system generation program 104 is also the same as a general user program, and operates under the operating system of the computer system. Therefore, when generating a new system, the operating system for running the program for system generation is called the driving operating system, and the newly created operating system is called the target operating system. 1 is a system block diagram of a compound computer system showing an embodiment.

It is output to an output device such as Further, the catalog data set 206 is a data set that manages the location of the data set (for example, the volume in which the data set is located, the position therein, etc.). These data sets are not directly relevant to the present invention.

How to handle 05,206 and system communication device 204
It is necessary that the rules and handling of information communicated via the computer system 201 are consistent among the computer systems 201 making up the compound computer system. On the other hand, the specifications for the non-shared input/output device group 203 and the specifications specific to each computer system corresponding to the type of work executed by each computer system 201 need to be done individually for each computer system 201. It is.

FIG. 3 is a diagram showing an example of the parameter configuration of system generation parameters in the present invention.

In FIG. 3, parameters in the range 301 are system common generation parameters common to each computer system 201 that makes up the compound computer system, and parameters in a range 302 are common generation parameters for each computer system 201 that makes up the compound computer system. These are system-specific generation parameters that can be specified uniquely for each system. As shown in the range 303, system-specific generation parameters include a PROC (abbreviation for procedure) parameter that allows you to set multiple parameters and give a name to the set. MOD whose name is indicated by 304
Specify in the EL parameter. In this way, we can give names to sets of multiple parameters and define these sets as M
When used as an ODEL parameter, its name is specified, so the number of system-specific generation parameters to be specified can be reduced.

The parameters shown in FIG. 3 are thus specified by the user when creating the system. For example, for computer system l, a system is generated by specifying option l, option 2, option 3, and option 4, and for computer system 2, option l, option 2, option 3, and option 5 are specified.

In this way, if the user wants to use the function of Option 1, he can specify it, and the table and program (module) for realizing the function of Option 1 are built into the target operating system.

FIG. 4 is a processing flowchart of the system generation program according to the present invention and a format diagram of an internal table used by the system generation program.

FIG. 4(b) shows a generation parameter storage table 410 for storing the generation parameters shown in FIG. This table 410 is composed of a plurality of sets of computer system-specific fields 4101 for each computer system making up the compound computer system. Furthermore, the field 41o1 for each computer system includes a system-common generation parameter storage area 4102 and a system-specific generation parameter storage area 4.

This generation parameter storage table 410 is
It is stored in the main memory and exists temporarily only during the generation process shown in FIG. 4(a).

As system-specific parameters, it is not possible to specify parameters that cause inconsistency in each computer system, or parameters that must be common to each computer system.These are specifications that must be specified as system-common parameters. do. Therefore, after creating the storage table,
Basically, there is no need to check for contradictions.

In FIG. 4(a), the system generation program first reads the generation parameters shown in FIG. 3 (step 401). Next, it is determined whether the read generation parameter is a system-common generation parameter or a system-specific generation parameter (step 402), and if it is a system-common generation parameter (YES), It is stored in the system-common generation parameter storage area 4102 of the field 4101 for all computer systems (step 4o3). Also,
If it is a system-specific generation parameter (No), it is stored in the system-specific generation parameter storage area 4103 of the field 4101 for each computer system (step 404). Next, it is determined whether or not the final generation parameters have been processed (step 405), and if not, the processes of steps 401 to 404 are repeatedly executed. Once the final generation parameters are reached,
All system-specific generation parameter storage areas 4103 of the generation parameter storage table 410 created in the process up to step 404 are investigated, and the MO
Connect the DEL parameter and PROC parameter,
Solve from PROC parameters corresponding to MODEL parameters and expand into individual parameters (Step 4

Note that in step 406, the information is expanded into individual parameters, which is a necessary process for translating into actual specifications.

According to the flow shown in FIG. 4(a), system resident volumes for a plurality of computer systems are created in one generation process. In a complex system made up of multiple computer systems, a system resident volume is required for each computer system making up the complex system. At this time, if the ○S (operating system) generated in each system resident volume has different roles, such as common options for each computer system and execution of different tasks for each computer system,
Each computer system will have its own options.

In the present invention, these are called system-common generation parameters and system-specific generation parameters.

The repetition of steps 401 to 405 in FIG. 4(a) is as follows:
This process is repeated as many times as the number of parameters shown in FIG. That is, in FIG. 3, C0MM0N PA
RAM is a system common generation parameter, and SY
STEMn PARAM is a system-specific generation parameter. The latter are each composed of a plurality of parameters, and steps 401 to 405 perform repeated processing on all these parameters. Thereafter, a plurality of computer systems are collectively generated according to the contents of the 411(b) table generated through these processes.

In this way, in this embodiment, system-specific generation parameters that can be specified uniquely to each computer system constituting a compound computer system, and system-common generation parameters that must be common to the compound computer system. Parameters are determined and classified, and unique names are added to some or all of the system-specific generation parameters specified for one computer system constituting the compound computer system, and those unique names are assigned to the compound computer system. Specify it in the system-specific generation parameters of other computer systems. As a result, we reconfigure the system generation parameters from both parameters,
Since the system resident volume is generated from this parameter, there will be no mutual contradiction. Furthermore, it is possible to reduce the number of generation parameters specified for the entire compound computer system.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to prevent mutual contradiction between the systems generated on the system resident volume of each computer system, thereby preventing system generation errors in the complex computer system. Furthermore, the number of parameters to be specified can be reduced when specifying parameters in system generation that generates a system on the system resident volume of each computer system constituting the compound computer system.
