Description

  The present invention relates to a virtual information processing system in which client environments are integrated on a server, and a virtual information processing method thereof.

  In recent years, thin client systems in which client environments are integrated on a server have attracted attention from the viewpoint of security. For example, there is known a thin client system in which a server side collectively manages which user can use which client environment from which terminal by associating the client environment, the user and the user terminal (see Patent Document 1). ). By using this thin client system to manage the client environment of the connection destination and assign it to the user, it becomes possible to use a method (shared virtual PC method) in which a plurality of client environments are shared and used by a plurality of people.

  In the shared virtual PC method, it is not always decided which virtual PC a user uses. For this reason, user-specific information (user profile) is often acquired by a file server or the like when logging on to a virtual PC, and often used together with technology (mobile user profile) returned to the file server when logging off.

  However, when using a mobile user profile, acquisition and return of the profile occur each time the user logs on or logs off. For this reason, at the time of simultaneous logon / logoff such as at the start of work / at the end of work, there is a concern that the CPU of the virtual PC and the network load increase, causing problems such as so-called logon storm.

  As a recent technology, there is a technology called user profile disk. This is expected to be a solution to the logon storm by cutting out the user profile portion as a disk, mounting it at logon, and using it. However, this technology mounts a disk on the OS and uses it. For this reason, there is also a problem that one user can not use it when using a plurality of environments.

  On the other hand, when using two client environments at the same time, there is known a technique of re-mounting to the one used later (the first one is unmounted) (see Patent Document 2). Even with this technology, the above problems can not be fundamentally solved.

  Also, as another logon storm countermeasure plan, for example, by keeping user profiles for all users in all virtual PCs and performing synchronization so as to be always up-to-date, logon storm can be prevented. However, even with this countermeasure, it is easily assumed that other problems such as an increase in load for synchronization and an increase in disk capacity for holding user profiles for all users may occur.

  The present invention has been made to solve such problems, and a virtual information processing system, a virtual information processing method, and a program that can reduce the disk capacity while reducing the processing load at the time of logon or logoff. The main purpose is to provide.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram of a virtual information processing system according to an embodiment of the present invention. The virtual information processing system 100 according to the present embodiment communicates with a client environment server 30 having a plurality of client environments (1, 2,...) That perform virtual information processing, and the client environment server 30, and the client environment A plurality of terminals 10 using each client environment (1, 2,...) Of the server 30, and a file server 40 communicably connected to the client environment server 30 and storing in advance a profile of a user of the terminal 10 ing

  When the terminal 10 logs on to each client environment (1, 2,...) Of the client environment server 30, each client environment (1, 2,...) Acquires the profile of the corresponding user from the file server 40. .

  Each client environment (1, 2,...) Of the client environment server 30 uses the client user of the original user when the terminal 10 uses each client environment (1, 2,...) Of the client environment server 30. It has snapshot means 31-2 for extracting a difference that has been changed from the profile.

Also, since only the difference from the original profile is stored, the disk capacity can be reduced. That is, the disk capacity can be reduced while reducing the processing load at the time of logon or logoff.

Embodiment 1
FIG. 2 is a block diagram showing a schematic system configuration of the virtual information processing system according to the first embodiment of the present invention. The virtual information processing system 100 according to the present embodiment is a session management that distributes a plurality of terminals 10 (10-1, 10-2,...) Which are clients and a client environment (1, 2,...) A client environment server 30 having a server 20, client environments (1, 2,...), And a file server 40 for storing profiles 1, 2,. Is equipped.

  The session management server 20, the client environment server 30, and the file server 40 are, for example, a central processing unit (CPU) that performs arithmetic processing and the like, an arithmetic program executed by the CPU, and a read only memory (ROM) in which control programs and the like are stored. The hardware configuration is centered on a microcomputer consisting of a memory consisting of RAM and a random access memory (RAM), an interface unit (I / F) that inputs and outputs signals with the outside, and the like. The CPU, the memory, and the interface unit are mutually connected via a data bus and the like.

  The terminals 10, the session management server 20, the client environment server 30, and the file server 40 are mutually connected via, for example, a communication network. Each terminal 10 is, for example, a PC (Personal Computer). Each terminal 10 connects to client environments (1, 2,...) In the client environment server 30, and utilizes the client environments (1, 2,...) Respectively.

  The session management server 20 responds to a request from the terminal 10 of each user (1, 2,...) To the appropriate client environment (31, 32,...) That the client environment server 30 has. Allocate to The session management server 20 has a session management unit 21 and a management database 22.

  The management database 22 stores a connection destination management table. For example, as shown in FIG. 3, the connection destination management table includes a client environment (1,...) And users (none, user 2,...) Using the client environment (1,...) , Is a table information in which. The connection destination management table is table information for managing which user's terminal 10 is using which client environment (1,...).

  The session management unit 21 refers to the connection destination management table 22 of the management database 22 according to the request from the terminal 10 of each user (1, 2,...) Allocate appropriate (currently unused) client environments (1, 2,...) To the terminal 10. Thereby, each user's terminal 10 can utilize each client environment, respectively, without competing with another user's terminal 10.

  The client environment server 30 has a plurality of client environments (1, 2,...). Each client environment (1, 2,...) Has a plurality of OSs (Operating Systems), applications, etc. used by users (1, 2,...).

  Each client environment (1, 2,...) Includes a client environment processing unit (31-1), a snapshot processing unit (31-2), a profile storage unit 31-3, and a difference storage unit 31-4. And.

  The client environment processing unit (31-1) performs processing in the client environment (1, 2,...). The snapshot processing unit (31-2) is one specific example of snapshot means, and snapshots the difference of profiles. The profile storage unit 31-3 stores profiles (1,...) Of users (1, 2,...). The difference storage unit 31-4 stores differences (1, 2,...) From the original profile that occur when the user's terminal 10 uses the client environment.

  The file server 40 has a snapshot processing unit 41 that processes a snapshot-processed differential profile, and a profile database 42 that stores user profiles (1, 2,...).

Next, an example of the operation of the virtual information processing system according to the present embodiment will be described.
For example, in the initial state of the virtual information processing system 100, the difference 1 from the profile 1 and the original profile does not exist in the client environment 1 (31).
The terminal 10-1 of the user 1 accesses the session management server 20.

  When the terminal 10-1 of the user 1 accesses the session management server 20, the session management unit 21 of the session management server 20 confirms the connection destination setting table of the management database 22.

  For example, when the connection destination setting table is set as shown in FIG. 3, the session management unit 21 follows the connection destination setting table to display the client environment 1 corresponding to the user “in use” as the terminal 10 of the user 1-. Distribution instruction to 1.

  The terminal 10-1 of the user 1 connects to the client environment 1 of the client environment server 30 according to the distribution instruction of the session management server 20, and logs on.

  At the time of logon, the client environment processing unit 31-1 of the client environment 1 of the client environment server 30 acquires the profile 1 of the user 1 from the profile database 42 of the file server 40. Thereafter, the terminal 10-1 of the user 1 starts using the client environment 1 of the client environment server 30 using the acquired profile 1.

  While the terminal 10-1 of the user 1 is using the client environment 1 of the client environment server 30, the snapshot processing unit 31-2 of the client environment 1 transmits the information of the new profile 1 to the profile storage unit 31-3. save.

  The snapshot processing unit 31-2 of the client environment 1 extracts only the changed difference between the original profile 1 of the profile storage unit 31-3 and the new profile 1, and the extracted difference is the original profile The difference is stored in the difference storage unit 31-4 as a difference from 1. Thus, since only the difference from the original profile 1 is stored, its disk capacity can be reduced.

  At the time of logoff, the file server 40 acquires the difference from the profile 1 stored in the difference storage unit 31-4 of the client environment 1 of the client environment server 30. As described above, only the difference from the profile 1 whose capacity is reduced is copied to the file server 40 at the time of logoff. Therefore, the processing load can be reduced.

  The snapshot processing unit 41 of the file server 40 combines the difference from the profile 1 acquired from the difference storage unit 31-4 of the client environment 1 of the client environment server 30 and the profile 1 of the profile database 42. Then, the snapshot processing unit 41 sets the synthesized one as a new profile 1 and stores the new profile 1 in the profile database 42.

  Thereafter, the client environment 1 of the client environment server 30 deletes the difference from the profile 1 that has become unnecessary from the difference storage unit 31-4. The snapshot processing unit 41 of the file server 40 deletes the unnecessary original profile 1 from the profile database 42. Thus, disk capacity can be saved by deleting differences and profiles from unnecessary profiles.

  As described above, according to the virtual information processing system 100 according to the present embodiment, the amount of profiles copied to the file server 40 at the time of logoff can be minimized, and the load thereof can be reduced. Also, since only the difference from the original profile is stored, the disk capacity can be reduced. That is, the disk capacity can be reduced while reducing the processing load at the time of logon or logoff.

Embodiment 2
FIG. 4 is a block diagram showing a schematic system configuration of a virtual information processing system according to a second embodiment of the present invention. The profile storage unit 31-3 of each client environment (1, 2,...) Of the client environment server 30 of the virtual information processing system 200 according to the second embodiment includes all users (1, 2,. The common profile (base profile) is stored. Also, in the difference storage unit 31-4, from the base profile generated when the terminal 10 of each user (1, 2,...) Uses each client environment (1, 2,...) The difference profile which is the difference of is stored. Similarly, in the profile database 42 of the file server 40, base profiles and differential profiles (1, 2,...) Are stored.

  The other configuration is substantially the same as that of the first embodiment, so the same reference numerals are given to the same portions and the detailed description will be omitted.

Next, an example of the operation of the virtual information processing system according to the present embodiment will be described.
For example, in the initial state of the virtual information processing system 200, the differential profile 1 does not exist in the profile storage unit 31-3 of the client environment 1.

  The base profile is a profile common to all users. Therefore, each client environment (1, 2,...) Of the client environment server 30 acquires and holds a base profile in advance from the profile database 42 of the file server 40. As a result, there is no need for each client environment (1, 2,...) To acquire a base profile from the file server 40 when each terminal 10 logs on, so the processing load can be reduced.

The terminal 10-1 of the user 1 accesses the session management server 20.
When the terminal 10-1 of the user 1 accesses the session management server 20, the session management unit 21 of the session management server 20 confirms the connection destination setting table of the management database 22.

  For example, when the connection destination setting table is set as shown in FIG. 3, the session management unit 21 follows the connection destination setting table to display the client environment 1 corresponding to the user “in use” as the terminal 10 of the user 1-. Distribution instruction to 1.

  The terminal 10-1 of the user 1 connects to the client environment 1 of the client environment server 30 according to the distribution instruction of the session management server 20, and logs on.

  At the time of logon, the client environment processing unit 31-1 of the client environment 1 of the client environment server 30 acquires the differential profile 1 of the user 1 from the profile database 42 of the file server 40. Thereafter, the terminal 10-1 of the user 1 starts using the client environment 1 of the client environment server 30.

  While the terminal 10-1 of the user 1 is using the client environment 1 of the client environment server 30, the snapshot processing unit 31-2 of the client environment 1 transmits the information of the new profile 1 to the profile storage unit 31-3. save. The snapshot processing unit 31-2 extracts the difference between the stored new profile 1 and the base profile, and using this difference, the difference profile 1 of the difference storage unit 31-4 without changing the base profile. Update only. As described above, only the difference profile which is the difference from the base profile is stored and updated in the difference storage unit 31-4, so that the disk capacity can be reduced.

  At the time of logoff, the file server 40 acquires the difference profile 1 of the difference storage unit 31-4 of the client environment 1 of the client environment server 30. As described above, at the time of logoff, only the differential profile (difference from the base profile) whose capacity is reduced is copied to the file server 40. Therefore, the processing load can be reduced.

  The snapshot processing unit 41 of the file server 40 stores the difference profile 1 acquired from the difference storage unit 31-4 of the client environment 1 of the client environment server 30 as a new difference profile 1 in the profile database 42.

  After that, the client environment 1 of the client environment server 30 deletes the original difference profile 1 that has become unnecessary from the difference storage unit 31-4. The snapshot processing unit 41 of the file server deletes the unnecessary difference profile 1 from the profile database 42. Thus, disk capacity can be saved by deleting unnecessary differential profiles.

  As described above, according to the virtual information processing system 200 according to the second embodiment, each client environment (1, 2,...) Does not need to acquire a base profile from the file server 40 when each terminal 10 logs on. Therefore, the processing load can be reduced. Further, even at the time of logoff, only the differential profile whose capacity is reduced is copied to the file server 40, so that the processing load can be reduced. Furthermore, since only the differential profile which is the differential from the base profile is stored and updated, its disk capacity can be reduced. That is, the disk capacity can be reduced while reducing the processing load at the time of logon and logoff.

Embodiment 3
FIG. 5 is a block diagram showing a schematic system configuration of a virtual information processing system according to a third embodiment of the present invention. The virtual information processing system 300 according to the present embodiment is configured by combining the first and second embodiments. That is, the snapshot processing unit 31-2 of each client environment (1, 2,...) Of the client environment server 30 uses the base profile while taking a snapshot of the difference profile (1, 2,...) And manage the differences from the difference profile (1, 2,...).

  Base profiles and differential profiles (1, 2,...) Are stored in the profile storage unit 31-3 of each client environment (1, 2,...) Of the client environment server 30. The difference from the difference profile (1, 2,...) Generated when the terminal 10 of each user uses the client environment (1, 2,...) Is stored in the difference storage unit 31-4. It is memorized one by one.

  The other parts of the configuration are substantially the same as in the first and second embodiments, so the same reference numerals are given to the same parts and a detailed description will be omitted.

Next, an example of the operation of the virtual information processing system according to the present embodiment will be described.
For example, in the initial state of the virtual information processing system 300, in the profile storage unit and 31-3 and the difference storage unit 31-4 of the client environment 1, the difference profile 1 which is the difference from the base profile and the difference profile 1 There is no difference.

  The base profile is a profile common to all users. Therefore, each client environment (1, 2,...) Of the client environment server 30 acquires and holds a base profile in advance from the profile database 42 of the file server 40. As a result, there is no need for each client environment (1, 2,...) To acquire a base profile from the file server 40 when each terminal 10 logs on, so the processing load can be reduced.

The terminal 10-1 of the user 1 accesses the session management server 20.
When the terminal 10-1 of the user 1 accesses the session management server 20, the session management unit 21 of the session management server 20 confirms the connection destination setting table of the management database 22.

  For example, when the connection destination setting table is set as shown in FIG. 3, the session management unit 21 follows the connection destination setting table to display the client environment 1 corresponding to the user “in use” as the terminal 10 of the user 1-. Distribution instruction to 1.

  The terminal 10-1 of the user 1 connects to the client environment 1 of the client environment server 30 according to the distribution instruction of the session management server 20, and logs on.

  At the time of logon, the client environment processing unit 31-1 of the client environment 1 of the client environment server 30 acquires the differential profile 1 of the user 1 from the profile database 42 of the file server 40. Thus, at the time of logon of each terminal 10, each client environment (1, 2,...) Does not need to acquire a base profile from the file server 40, and only needs to acquire a differential profile with a small capacity. Therefore, the processing load can be reduced. Thereafter, the terminal 10-1 of the user 1 starts using the client environment 1 of the client environment server 30.

  While the terminal 10-1 of the user 1 is using the client environment 1 of the client environment server 30, the snapshot processing unit 31-2 of the client environment 1 does not change the base profile and the difference profile 1; The difference with the difference profile 1 is extracted, and only the difference is updated from the difference profile 1 of the difference storage unit 31-4 using this difference. As described above, only the difference from the difference profile 1 whose capacity is reduced is stored and updated, so that the disk capacity can be reduced.

  At the time of logoff, the file server 40 acquires only the difference from the difference profile 1 of the difference storage unit 31-4 of the client environment 1 of the client environment server 30. Thus, when logging off, only the difference from the differential profile with a smaller capacity (which is smaller than the differential profile) is copied to the file server 40. Therefore, the processing load can be reduced.

  The snapshot processing unit 41 of the file server 40 combines the difference from the difference profile 1 acquired from the difference storage unit 31-4 of the client environment 1 of the client environment server 30 and the difference profile 1 of the profile database 42. Then, the snapshot processing unit 41 sets the synthesized one as a new difference profile 1 and stores it in the profile database 42.

  The client environment 1 of the client environment server 30 deletes the difference from the original difference profile 1 that has become unnecessary from the difference storage unit 31-4. The snapshot processing unit 41 of the file server 40 deletes from the profile database 42 the original differential profile 1 that has become unnecessary. Thus, disk capacity can be saved by deleting differences and difference profiles from unnecessary difference profiles.

  After that, the client environment 1 combines the remaining difference profile 1 and the difference from the difference profile 1, but this combination may not be performed. By performing the combination, the amount of profiles copied to the file server 40 at the time of logoff can be made smaller, and the processing load can be reduced.

  As described above, according to the virtual information processing system 300 according to the present embodiment, each client environment (1, 2,...) Does not need to acquire a base profile from the file server 40 when each terminal 10 logs on. Since it is only necessary to acquire only a small differential profile, the processing load can be reduced. Further, at the time of logoff, only the difference from the difference profile whose capacity is reduced is copied to the file server 40, so that the processing load can be reduced. Furthermore, the disk capacity can be reduced because only the differences from the difference profiles (1, 2,...) Whose capacities are reduced are stored and updated. That is, the disk capacity can be reduced while reducing the processing load at the time of logon and logoff.

Embodiment 4
FIG. 6 is a block diagram showing a schematic system configuration of a virtual information processing system according to a third embodiment of the present invention. The file server 40 according to the present embodiment does not combine the differences from the difference profiles (1, 2,...) Extracted by the snapshot with the difference profiles (1, 2,...), But as difference information Hold it as it is. Then, the client environments (1, 2,...) Of the client environment server 30 use only the difference information at the time of logon / logoff.

  The management database 44 of the file server 40 stores, for example, a difference management table as shown in FIG. The difference management table is a table in which each client environment (1, 2,...) Is associated with difference information (difference profile...) Held by each client environment (1, 2,...) It is information. The difference management table stores which difference profile exists in which client environment. The file server 40 has a profile management unit 43 that manages difference information of the held profile in a difference management table.

  The other parts of the configuration are substantially the same as in the first and second embodiments, so the same reference numerals are given to the same parts and a detailed description will be omitted.

Next, an example of the operation of the virtual information processing system according to the present embodiment will be described.
For example, in the initial state of the virtual information processing system 400, the differential profile 1-1 and the differential profile 1-2 do not exist in the profile database 42 of the file server 40. Further, in the client environment 1 of the client environment server 30, there is no difference from the base profile, and in the client environment 2, there is no difference from the difference profile 1-1 and the difference profile 1-1.

  The base profile is a profile common to all users. Therefore, each client environment (1, 2,...) Of the client environment server 30 acquires and holds a base profile in advance from the profile database 42 of the file server 40. As a result, there is no need for each client environment (1, 2,...) To acquire a base profile from the file server 40 when each terminal 10 logs on, so the processing load can be reduced.

The terminal 10-1 of the user 1 accesses the session management server 20.
When the terminal 10-1 of the user 1 accesses the session management server 20, the session management unit 21 of the session management server 20 confirms the connection destination setting table of the management database 22.

  For example, when the connection destination setting table is set as shown in FIG. 3, the session management unit 21 follows the connection destination setting table to display the client environment 1 corresponding to the user “in use” as the terminal 10 of the user 1-. Distribution instruction to 1.

  The terminal 10-1 of the user 1 connects to the client environment 1 of the client environment server 30 according to the distribution instruction of the session management server 20, and logs on.

  At the time of logon, the client environment processing unit 31-1 of the client environment 1 accesses the profile management unit 43 of the file server 40, and confirms which difference profile exists in each client environment (1, 2,...) .

  At this time, the difference management table (43) is, for example, as shown in FIG. Since there is no difference profile (no difference information) in each client environment (1, 2,...), The client environment processing unit (31-1) does not perform any processing, and the terminal 10-1 of the user 1 , Start using the client environment 1 of the client environment server 30.

  While the terminal 10-1 of the user 1 is using the client environment 1 of the client environment server 30, the snapshot processing unit 31-2 of the client environment 1 does not change the base profile of the profile storage unit 31-3. , The difference with the base profile is extracted, and only the difference from the base profile of the difference storage unit 31-4 is updated using this difference. Thus, the disk capacity can be reduced because the difference from the base profile is stored and updated.

  At the time of logoff, the file server 40 acquires only the difference from the base profile of the difference storage unit 31-4 of the client environment 1 of the client environment server 30. Thus, at logoff, only the difference from the base profile whose capacity is reduced is copied to the file server 40. Therefore, the processing load can be reduced.

  The snapshot processing unit 41 of the file server 40 stores the difference from the base profile in the profile database 42 as a difference profile 1-1.

  The profile management unit 43 updates the difference management table of the management database 44 in accordance with the difference profile 1-1 stored in the profile database 44. For example, the difference management table is changed as shown in FIG.

Thereafter, the terminal 10-1 of the user 1 accesses the session management server 20 again.
When the terminal 10-1 of the user 1 accesses the session management server 20, the session management unit 21 of the session management server 20 confirms the connection destination setting table of the management database 22.

  For example, when the connection destination setting table is set as shown in FIG. 9, the session management unit 21 distributes the client environment 2 corresponding to the currently used user “none” to the terminal of the user 1 according to the connection destination setting table. To direct.

The terminal 10-1 of the user 1 connects to the client environment 2 of the client environment server 30 according to the distribution instruction of the session management server 20, and logs on.
At logon time, the client environment processing unit 31-1 of the client environment 2 accesses the profile management unit 43 of the file server 40, and confirms which differential profile exists in each client environment (1, 2,...) .

  At this time, the difference management table is, for example, as shown in FIG. A difference profile 1-1 exists in the client environment 1. Therefore, the client environment 2 acquires the difference profile 1-1 of the client environment 1 from the client environment 1 according to the difference management table (43). In this manner, the difference management table can be confirmed, and the necessary difference profile can be acquired from another client environment in the client environment server 30 instead of acquiring from the file server 40. As a result, if the differential profile remains in another client environment, it can be used effectively, and the amount of profile copy at logon can be further reduced.

  The terminal 10-1 of the user 1 starts using the client environment 2 of the client environment server 30.

  While the terminal 10-1 of the user 1 is using the client environment 2 of the client environment server 30, the snapshot processing unit 31-2 of the client environment 2 does not change the base profile of the profile storage unit 31-3. The difference between the new profile and the base profile is extracted, and only the difference from the base profile of the difference storage unit 31-4 is updated using this difference. As a result, the disk capacity can be reduced because the difference from the base profile is stored and updated as described above.

At the time of logoff, the file server 40 acquires only the difference from the difference profile 1-1 of the difference storage unit 31-4 of the client environment 1 of the client environment server 30. As a result, as described above, only the difference from the base profile whose capacity is reduced is copied to the file server 40 at the time of logoff, and the processing load can be reduced.
The snapshot processing unit 41 of the file server 40 stores the difference from the difference profile 1-1 in the profile database 42 as a difference profile 1-2.

The profile management unit 43 updates the difference management table of the management database 44 in accordance with the difference profile 1-2 stored in the profile database 42. For example, the difference management table is changed as shown in FIG.
Thereafter, the terminal 10-1 of the user 1 accesses the session management server 20 again.

  When the terminal 10-1 of the user 1 accesses the session management server 20, the session management unit 21 of the session management server 20 confirms the connection destination setting table of the management database 22.

  For example, when the connection destination setting table is set as shown in FIG. 3, the session management unit 21 distributes the client environment 1 corresponding to the user “in use” to the terminal of the user 1 according to the connection destination setting table. To direct.

  The terminal 10-1 of the user 1 connects to the client environment 1 of the client environment server 30 according to the distribution instruction of the session management server 20, and logs on.

  At the time of logon, the client environment processing unit 31-1 of the client environment 1 accesses the profile management unit 43 of the file server 40, and confirms which difference profile exists in each client environment (1, 2,...) .

  At this time, the difference management table of the management database 44 is, for example, as shown in FIG. There are differential profiles 1-1 and 1-2 in the client environment 2. Therefore, the client environment 1 acquires the difference profile 1-2 of the client environment 2 from the client environment 2 according to the difference management table. As a result, if the differential profile remains in another client environment, it can be used effectively, and the amount of profile copy at logon can be further reduced.

  The terminal 10-1 of the user 1 starts using the client environment 1 of the client environment server 30. In the present embodiment, at the time of logon, each client environment copies the differential profile from the file server 40. However, the session management unit 21 and the profile management unit 43 cooperate with each other, for example, immediately before logging on. A copy of the profile may be implemented. This can further reduce the processing load at the time of logon.

  As described above, according to the virtual information processing system according to the present embodiment, each client environment (1, 2,...) Does not need to acquire a base profile from the file server 40 when each terminal 10 logs on, The processing load can be reduced. At the time of logoff, only the difference from the base profile whose capacity is reduced is copied to the file server 40, so that the processing load can be reduced. Because the difference from the base profile is stored and updated, its disk capacity can be reduced. Furthermore, if the differential profile remains in other client environments, it can be used effectively, and the amount of profile copy at logon can be further reduced. That is, the disk capacity can be reduced while reducing the processing load at the time of logon and logoff.

The present invention is not limited to the above embodiment, and can be appropriately modified without departing from the scope of the present invention.
The present invention can also realize, for example, the processing executed by the session management server 20, the client environment server 30, and the file server 40 described above by causing a CPU to execute a computer program.

  The programs can be stored and provided to a computer using various types of non-transitory computer readable media. Non-transitory computer readable media include tangible storage media of various types. Examples of non-transitory computer readable media are magnetic recording media (eg flexible disk, magnetic tape, hard disk drive), magneto-optical recording media (eg magneto-optical disk), CD-ROM (Read Only Memory), CD-R, CD-R / W, semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)) are included.

  Also, the programs may be supplied to the computer by various types of transitory computer readable media. Examples of temporary computer readable media include electrical signals, light signals, and electromagnetic waves. The temporary computer readable medium can provide the program to the computer via a wired communication path such as electric wire and optical fiber, or a wireless communication path.
