FIG. 3 is a flowchart for explaining the operation of the startup processing method according to the first embodiment of the present invention. FIG. 4 is a diagram showing data of the startup processing method according to the first embodiment of the present invention. Prior to the execution of the flow of FIG. 3, an execution server table as shown in FIG. 4 is created in the client terminal device 1 and stored in the hard disk device 15. As shown in FIG. 4, in the execution server table, a plurality of file name extensions (hereinafter simply referred to as “extensions”) are associated, and the server names on which the programs having the extensions in the file names are executed. And the shared path name to which the program file belongs is registered. The shared path name is information indicating a route (path) to a folder in which a group of files stored in the storage means having a hierarchical structure is stored. As shown in FIG. 3, first, a calling process that is being executed (a process is a CPU 1
1 reads the execution server table from the memory 12 and, for example, an extension of the file name of a program to be started (hereinafter referred to as a start process) incorporated in the program being executed. Is checked in the execution server table. That is, first, the first extension in the execution server table is read out (step S1) and compared with the extension of the startup process (step S2). And
If the two extensions do not match (NO in step S2) and the next extension is registered in the execution server table, that is, if the comparison is not completed (step S3
No), the next extension is read from the execution server table (step S1), and the extension is compared with the extension of the startup process (step S2). When the same extension as that of the startup process is found in the execution server table (Yes in step S2), the calling process under execution stores the server name and the shared path name associated with the found extension in the execution server table. (Step S4).

Subsequently, the calling process determines whether the read server name or the like is valid information, that is, whether the read server name is not an empty character string (step S5). In the example of FIG. 4, when the extension is “abc”, it is determined that valid information is registered because it is not a blank character.
In the case of "i", since it is an empty character, it is determined that valid information is not registered. If it is determined that valid information is registered (Y in step S5)
es) A process start request including the start process name and the read shared path name is issued to the server 2 having the read server name via the communication control unit 17. Thus,
The server 2 that has received the process activation request activates the designated activation process belonging to the designated shared path and calls various functions (step S6). Further, after the execution, the execution result is passed from the server 2 to the client terminal device 1 that has issued the process activation request. On the other hand, if it is determined in step S5 that valid information is not registered (No in step S5), a local (in the own client terminal device) designated process is started to activate various functions. A call is made (step S7). If it is determined in step S3 that the next extension is not registered in the execution server table (Yes in step S3)
s) The process exits the flow of this operation and does not start the specified start process or starts the local specified process. Thus, according to the first embodiment of the present invention, by using the extension of the program file to be activated, load distribution (execution location distribution) can be achieved in the network, and therefore, the number of waiting times can be reduced. Execution results can be obtained in time.

Next, a second embodiment of the present invention will be described in detail with reference to the drawings. FIG. 5 is a flowchart for explaining the operation of the startup processing method according to the second embodiment of the present invention. FIG. 6 is a diagram showing data of a startup processing method according to the second embodiment of the present invention. Prior to the execution of the operation flow of FIG. 5, an execution server table as shown in FIG. 6 is created in the client terminal device 1 and stored in the hard disk device 15. afterwards,
In this embodiment, first, the executing calling process reads the execution server table into the memory 12, and for example, the extension of the file name of the startup process incorporated in the executing program is included in the execution server table. Check whether it is registered. That is, first, the first extension in the execution server table is read (step S11) and compared with the extension of the startup process (step S12). If the two extensions do not match (No in step S12) and the next extension is registered in the execution server table, that is, if the comparison is not completed (No in step S13), the execution is performed. The next extension is read from the server table (step S11), and the extension is compared with the extension of the startup process (step S12). When the same extension as the startup process is found in the execution server table (Yes in step S12), the calling process reads the server name and the shared path name associated with the found extension from the execution server table ( If there is more than one, the first pair is read out) (step S14).

Subsequently, the calling process determines whether the read server name or the like is valid information, and when it is determined that valid information is registered, the calling process A process use right acquisition request including the startup process name and the read shared path name is issued to the server 2 of the read server name (if valid information is not registered, the process of the first embodiment is performed). Works similarly). Then, the server 2 receiving the process start request determines whether or not the specified start process belonging to the specified shared path is being executed, and if not, that is, the process use right is released. If so, information is given to the effect that the process use right is given to the client terminal device 1 which has issued the process use right acquisition request. If the process use right is successfully acquired (Yes in step S16), the calling process in the client terminal device 1 determines the name of the server that has read the process start request including the start process name and the read shared path name. Issue to server 2. In this way, the server 2 that has received the process activation request activates the designated activation process belonging to the designated shared path and calls various functions (step S18). Further, after the execution, the execution result is passed from the server 2 to the client terminal device 1 that has issued the process activation request, and the right to use the process is released (step S19). On the other hand, in step S16, for example, when the usage right has not been acquired after waiting for a predetermined time (step S16
No), it is determined whether a pair of the next server name and the shared path name associated with the extension is registered in the execution server table (step S17), and if it is registered (step S17). Step S14 to Step S16 are repeated for the next pair. When there is no next pair (No in step S17), the flow of this operation is exited, and the specified start process is not started or the local specified process is started. Also, in step S13, when it is determined that the next extension is not registered in the execution server table (Yes in step S13), the process exits this operation flow and does not start the specified startup process. Or
Or launch a specified process locally. Thus, according to the second embodiment, the load can be distributed in the network by using the extension of the program file to be started, and if it cannot be executed by one server, it can be executed by another server. Since execution is possible, an execution result can be obtained with a shorter waiting time.

Next, a third embodiment of the present invention will be described in detail with reference to the drawings. In the third embodiment of the present invention, exclusion process information indicating whether or not exclusion process is necessary is stored in the execution server table in association with each extension.
When starting the boot program, the exclusion process is performed when the exclusion process information associated with the extension of the boot program indicates that the exclusion process is necessary. FIG. 7 is a flowchart for explaining the operation of the startup processing method according to the third embodiment of the present invention. FIG. 8 is a diagram showing data of a startup processing method according to the third embodiment of the present invention.
Prior to execution of the operation flow of FIG. 7, an execution server table as shown in FIG. 8 is created in the client terminal device 1 and stored in the hard disk device 15. Thereafter, in the third embodiment, first,
The executing calling process reads the execution server table into the memory 12 and checks whether, for example, the extension of the file name of the startup process incorporated in the executing program is registered in the execution server table. . That is, first, the first extension in the execution server table is read (step S21) and compared with the extension of the startup process (step S22). If the two extensions do not match (No in step S22) and the next extension is registered in the execution server table, that is, if the comparison is not completed (step S2).
(No in 3), reads the next extension from the execution server table (step S221), and compares the extension with the extension of the startup process (step S22). When the same extension as that of the startup process is found in the execution server table (Yes in step S22), the calling process reads the exclusive name as the exclusion processing information associated with the found extension from the execution server table. (Step S24) Further, the activation process name, the server name, and the shared path name are read (if there are a plurality of pairs of the server name and the shared path name, the first pair is read) (Step S25).

Subsequently, the calling process determines whether or not to perform the exclusion process by checking whether or not the read exclusive name is an empty character string (step S26). Is determined (Yes in step S26), the communication control unit 1
7, a process use right acquisition request including the read start process name and shared path name is issued to the server 2 having the read server name (step S27). Then, the server 2 receiving the process start request determines whether or not the specified start process belonging to the specified shared path is being executed, and if not, that is, the process use right is released. If so, information is given to the effect that the process use right is given to the client terminal device 1 which has issued the process use right acquisition request. In this manner, if the process use right is successfully acquired (Yes in step S28)
s) The calling process in the client terminal device 1 is the server 2 of the server name that has read the process start request including the start process name and the read shared path name.
Put out against. As a result, the server 2 that has received the process activation request activates the designated activation process belonging to the designated shared path and calls various functions (step S31). Further, when the execution result is passed from the server 2 to the client terminal device 1 that has issued the process activation request and exclusive control is performed (Yes in step S32), the process use right is released (step S33). .

On the other hand, in step S28, if, for example, the right of use has not been acquired after waiting for a predetermined time (No in step S28), the next file associated with the extension is stored in the execution server table. It is determined whether there is a pair of the server name and the shared path name (step S
29) If present (Yes in step S29), the next pair is read out, and steps S27 and S28 are repeated. Then, when there is no next pair (step S29)
No), the flow of this operation is exited, and the specified start process is not started or the local specified process is started. If it is determined that the exclusion process is not performed in step S26 (step S26).
(No in 26), the process immediately proceeds to the activation of the process in the designated server 2 (step S31). If it is determined in step S23 that the next extension is not registered in the execution server table (step S23).
At 23, the flow of this operation is exited, and the specified start process is not started, or the local specified process is started. Thus, according to the third embodiment, the load can be distributed in the network by using the extension of the program file to be started. At this time, the exclusive control registered in the execution server table in advance can be performed. Exclusive control may or may not be performed according to the information. In this embodiment, the startup process name is registered in the execution server table, and the process with the startup process name is started. However, the startup process name coded in the program of the calling process is used. Alternatively, it may be activated. In the above description, the shared path name is registered in the execution server table in association with the server name. However, the server 2 stores the start program (start process) from the extension in the start process name. A configuration is also possible in which the location is known and the shared path name is not registered. Further, each piece of information in the execution server tail shown in each embodiment is stored in each client terminal device 1, but the information is centrally managed, and the execution server table is stored in any one of the client terminal devices 1. When one of the information is updated, the information in all the client terminal devices 1 is similarly updated. For example, when the system administrator operates one client terminal device 1
When a new start process is added to one shared path of one server 2 by using the server 2, all the client terminal devices 1 on which the server 2 has the execution server table
The client terminal device 1 that has received the execution server table update request and adds the server name and the shared path name indicated in the update request in association with the extension information indicated in the update request. is there.
