Is managed by.

FIG. 6 shows a computer 1 for resource manager.
An example of relay management computer update information created by
It includes distribution information and deletion information corresponding to each relay management computer. In step S1, the resource manager specifies a file name to be updated, newly distributed, or deleted. You can specify one or more file names,
Alternatively, a directory or folder name may be used, but hereinafter, they are all referred to as "update file name".

Next, in step S2, it is checked whether or not there is an error in the update file name, and if there is an error, step S3
After displaying the error message with, the process ends. If there is no error in the updated file name, step S
In step S4, the relay management computer name is extracted from the relay information in FIG. 4, and in step S5, based on the extracted relay management computer name and the resource management information in FIG. It is determined whether or not a file resource is necessary, and the relay management computer update information of FIG. 6 is created. In the update information of FIG. 6, the distribution of the file name aaa, ccc, ddd, hhh, kkk is specified, and the file name l
This is an example when deletion of ll, ppp, qqq is specified.

Next, in step S6, the relay information is checked,
It is determined whether or not the update information for all the relay management computers has been created. If not completed, the process returns to step S4, and if completed, this process ends. In the above description, an example in which the resource manager instructs only the update file name has been shown, but a specific relay management computer or user computer name can be specified in addition to the update file name.

FIG. 7 is a flowchart showing an example of the file resource updating process of the relay management computer, which is executed by the resource manager computer 1. First, in step S11, the relay management computer name is fetched from the relay information in FIG. 4, and it is determined whether or not there is update information (FIG. 6) corresponding to the relay management computer name fetched in step S12. If not, step S20
Go to.

If the corresponding update information exists, it is checked in step S13 if the update information indicates the deletion of the file resource, and if so, the file resource of the relay management computer is deleted in step S14. To do. Subsequently, in step S15, it is checked whether the update information indicates the update or new distribution of the file resource. If not, the process proceeds to step S21.

When file resource update or new distribution is instructed, it is checked in step S16 whether or not these file resources can be stored in the resource storage area of the relay management computer, and, for example, free space If there is not enough space to store the data, an error message is displayed in step S17, and the process returns to step S11. If the file resource can be updated or newly distributed, it is checked in step S18 whether the file resource needs to be customized, and if necessary, the file resource is customized. This is, for example, according to the CPU type registered in the update information (FIG. 6) together with the file name, the format of the file resource to be transferred, such as a character code (for example, Kanji code shift JIS or EUC) or a control code (for example, Line feed code and
The EOF code etc.) is to be changed.

Then, in step S19, the file resource is transferred to the relay management computer. Here, the relay management computer to which the file resource is transferred is, for example,
The size of the transferred file resource is compared with the size of the same file resource notified from the resource manager's computer 1, and the file resources of different sizes are judged to have failed in transfer, and their file names are determined. Notify the resource manager computer 1. Needless to say, this judgment can be made by SUM or CRC.

The resource manager computer 1 judges the response from the relay management computer in step S20, and when the file name is notified, the process returns to step S19, and the file resource having the file name is transferred again. When the transfer or deletion of the file resource is completed, step S21
In step S22, the update information of the computer is transferred to the relay management computer. In step S22, it is determined whether or not the file resource update processing of all the relay management computers is completed. If not completed, the process returns to step S11 to complete. If so, this process ends.

FIG. 8 is a flow chart showing an example of the update information creation process of the user computer executed by the relay management computer. Further, FIG. 9 is a diagram showing an example of user information in which a computer name for a user is registered, and an area name for storing a file resource of the computer for the user and a CPU type are registered corresponding to the computer name for the user. . FIG. 10 is a diagram showing an example of user resource management information in which file resources required by the user computer are registered. These pieces of information are managed by the relay management computer.

FIG. 11 shows an example of user computer update information created by the relay management computer, which includes distribution information and deletion information corresponding to each user computer. The relay management computer executes step S3.
In step 1, the computer name for the user is extracted from the user information (FIG. 9), and in step S32, based on the resource management information for the user (FIG. 10) and the update information (FIG. 6) transferred from the computer 1 for resource manager, Update information (FIG. 11) corresponding to the extracted user computer name is created.
At this time, if the same file name is designated in duplicate in the process shown in FIG. 3, the duplicate file name is deleted, so the same file resource is transferred to the user computer in duplicate, or the same file resource is transferred. Repeated deletions of file resources do not occur.

Subsequently, in step S33, it is determined whether or not the update information of all the user computers has been created. If not completed, the process returns to step S31, and if completed, the resource is updated in step S34. Computer for administrator 1
After the update information transferred from is deleted, this process ends. FIG. 12 is a flowchart showing an example of the file resource updating process of the user computer, which is executed by the user computer before executing the process of using the file resource.

The user computer executes step S41.
Then, it is checked whether the relay management computer that relays and manages its own file resource has its own update information, and if there is no update information, this process is terminated. If there is update information of oneself, it is checked in step S42 whether deletion of the file resource is instructed in the update information,
If so, the file resource is deleted in step S43.

Then, in step S44, it is checked whether or not the update information indicates the update of the file resource or the new distribution. If not, the process proceeds to step S49. When the file resource update or new distribution is instructed, it is checked in step S45 whether or not the file resource can be stored in its own resource storage area, for example, the free space is too small to store the file resource. In such a case, in step S46, the error message is displayed, the error message is sent to the resource manager computer 1, and then this process is terminated.

If the file resource can be stored, in step S47, the file resource is read from the relay management computer based on the update information and saved in its own resource storage area. In step S48, for example, it is read. The size of the file resource is compared with the size of the file resource notified by the relay management computer to determine whether the file resource has been read normally. If not, the process returns to step S47 to return to normal. Reload the file resource that could not be read. Needless to say, this judgment can be made by SUM or CRC.

When the reading or deleting of the file resource is completed, the update information of its own stored in the relay management computer is deleted in step S49, and then this process is completed.
It will execute the process that uses the file resource. Of course, if the update of the file resource fails, the process is not executed and the resource manager waits for an appropriate action.

FIG. 13 is a diagram showing a specific example of the flow of update information and file resources. In order to simplify the description, in the figure, a resource manager computer 1, a relay management computer 5a and a user computer 2 are shown.
Only 1 was shown. In the figure, the resource manager computer 1 creates the relay management computer update information 23 from the relay information 21 and the resource management information 22. Then, based on the update information 23, for example, the file resource of the relay management computer 5a is updated. Specifically, the designated file resource is deleted from the file resources stored in the external storage device 15 and the like, and the external storage device 1
The designated file resource is transferred from the file resource stored in 1 or the like, and further, only the part 23 'corresponding to the relay management computer 5a in the update information 23 is transferred.

The file resource is updated, and the update information 2
The relay management computer 5a having received 3 ', the update information 23', the user information 24 and the user resource management information 2
The update information 26 of the user computer is created from 5. For example, the user computer 2a checks the update information 26 stored in the relay management computer 5a, and if there is update information corresponding to itself, it is stored in the external storage device 12 or the like based on the update information. The designated file resource is deleted from the file resource, and the designated file resource is read from the file resource stored in the external storage device 15 or the like and stored in the external storage device 12 or the like.

The relay information 21, the resource management information 22, the update information 23, etc. are connected to the resource manager computer 1 together with the resource manager program for executing the processes shown in FIGS. 3 and 7. It is stored in the external storage device 11 or the like. The user information 24, the user resource management information 25, the update information 23 ', etc. are stored in an external storage device connected to each relay management computer together with the relay management program for executing the processing shown in FIG. To be done. The user resource management program that executes the processing shown in FIG. 9 is stored in an external storage device or the like connected to each user computer.

As described above, according to this embodiment, the update information of the computer that manages the file resource is created and updated, the update information of the computer that uses the file resource is created, and the file of the computer that uses the file resource is created. The resource update and the resource update can be performed by different processes. Specifically, the file resource manager computer creates update information for the relay management computer and updates the file resource. The relay management computer creates update information for the user computer. The user computer will update its own file resource based on the update information created by the relay management computer.

Therefore, the information (update information) for managing the file resources is managed in a layered manner in the resource manager computer and each relay management computer,
The resource manager computer only has to manage the relay management computer, and does not have to manage the user computer. Further, the relay management computer may manage only the user computer.

Such a file resource management method is not limited to the above three layers, and can be easily expanded to an arbitrary number of layers. FIG. 14 is a diagram showing an example of a file resource management system in which the file resource management is expanded into four layers and a method thereof. Although a detailed explanation is omitted, the resource manager computer is the primary relay management computer, the primary relay management computer is the secondary relay management computer, and the secondary relay management computer is the user. Manage each computer. Also, it goes without saying that the user computers can be arranged in different layers, such as the third layer and the fifth layer.
