2. Description of the Related Art When a communication management program is started, a process of acquiring a shared memory area (a memory area shared by a plurality of processes of the communication management program) and a process of managing the communication management program on the shared memory area. To develop (table development) a table (table having information (resource management information) on the configuration, name, and attributes of the resource, etc.) necessary for controlling and managing resources on the network system "Initial setting process" is required.

In such an initialization process, a plurality of communication definition object files (a group of communication definition object files generated by a communication definition compiling program based on a group of communication definition source files) are read.
This is realized by expanding a table having resource management information and pointers to other tables on the shared memory area based on the communication definition object file group. In the communication management program, the initialization process at the time of starting the communication management program realizes the initial setting process.

Conventionally, in this type of initialization method at the time of starting a communication management program, the initialization processing is performed by one process.

Here, unless the initial setting process is completed,
Since the next operation in the startup processing of the communication management program cannot be executed, and other processes in the original processing of the communication management program cannot operate, it is highly necessary to end the initialization processing quickly. There is something.

Next, with reference to FIGS. 1, 2, 3, and 4, the operation of the communication management program startup initialization method according to the present embodiment configured as described above will be described in detail. I do.

When the communication management program 11 is started, first, the parent process 110 starts. This parent process 11
0 calls the initialization processing unit 100, which is a "function (subroutine for performing initialization)" existing in itself (at this time, the name of the communication definition main object file 21 is passed as a parameter).

Thus, the initial setting processing unit 100 performs the following initial setting processing (see FIG. 4).

First, the shared memory area acquiring means 101 in the initial setting processing section 100 executes the communication definition main object file 2 in the communication definition object file group 14.
1. Open the communication definition main object file 2
1 to the communication definition sub-object files 22, 23,
And the names and simple configurations of the communication definition sub-object files 22, 23 and 24 are read (step 401).

Next, the shared memory area obtaining means 101
Based on the “simple configuration of each communication definition sub-object file 22, 23, and 24” read in step 401, a table expansion of all communication definition object files (entire communication definition object file group 14) Based on this, a memory size required to perform a table having resource management information and a pointer on the shared memory area 150) is calculated (step 402), and the shared memory area 150 corresponding to the memory size is stored in the memory 15. (Step 403).

Further, shared memory area obtaining means 101
Is an area for the communication definition main object file 21 (main table section area in FIG. 2) and each of the communication definition sub object files 22, 23, and 24.
Is determined (step 404). In the shared memory area 150, each area (area where the communication definition sub-object files 22, 23, and 24 in FIG. 2 are expanded into a table) is expanded. As a result, each area as shown in FIG.
Is secured.

Thereafter, the child process allocating means 102
The required number (“the number of communication definition object files−1”, that is, the communication definition sub-object) is set so that the number of processes to be initialized is the same as the number of files (the number of communication definition object files) in the communication definition object file group 14. An initial setting child process 200 of the number of files is created (step 405). In the case of the present embodiment, as shown in FIG. 2, three initialization child processes 200 (initialization child processes 202, 203, and 204) for three communication definition sub-object files 22, 23, and 24 are set. ) To create.

In the process of creating the initialization child process 200 in step 405, the child process allocation means 102 executes the communication definition sub-object files 22 and 2
The names (file names) of the communication definition sub-object files 22, 23, and 24 read in step 401 so as to cause the initializer processes 202, 203, and 204 to execute the table expansion processing for 3, 3, and 24. To each of the initializer processes 20
2, 203, and 204.

Thus, the initialization processing unit 100 in the parent process 110 expands the table for the communication definition main object file 21, and the initialization child process 202 expands the table for the communication definition sub-object file 22. Each communication definition object file and each process are configured such that the initialization subprocess 203 expands the table for the definition sub-object file 23 and the initialization subprocess 204 expands the table for the communication definition sub-object file 24. It will be assigned on a one-to-one basis.

As described above, all the processes related to the initialization processing (the parent process 110 having the initialization processing unit 100 and each initialization child process 200) operate in parallel. That is, the initial setting processing unit 100
Of the communication definition main object file 21 by itself, as well as the initialization child processes 202, 203,
And 204 are independent table expansion processes (each communication definition sub-object file 22, 23, assigned to each of the initializer processes 202, 203, and 204).
And 24 are read and a table is developed in each area on the shared memory area 150 allocated to each of them.
Is passed to each of the initializer processes 202, 203, and 204 so as to perform (Step 406). As a result, the own table expansion processing by the table expansion means 103 and the table expansion processing of each of the initial setting child processes 202, 203, and 204 are simultaneously and independently executed in parallel.

When the table developing means 103 completes its own table developing processing (step 407), it waits for the end of the table developing processing of each of the initializer processes 202, 203 and 204 (step 408). Note that each of the initializer processes 202, 203, and 20
4 ends its process by itself after completing its own table expansion processing.

The table developing means 103 includes its own and all initialization child processes 202, 203 and 204.
When it is confirmed that the table expansion process has been completed normally (in the case of “Yes” in the judgment of step 409), the execution control is passed to the hash table integration / linking means 104.

Hash table integration / linking means 104
First, each communication definition sub-object file 2
Shared memory area 150 corresponding to 2, 23, and 24
A hash table in each area above (including a hash table when a hash table is also generated in the main table section area) is integrated to generate an integrated hash table (step 410). The individual hash tables are deleted after the processing of step 410.

Second, the hash table integration / linking means 104 sets the individual initializer processes 202, 202 in the shared memory area 150 in which the table has been developed.
Link relations between communication definition object files that could not be created (created) by themselves depending on 203 and 204 (pointing to a table group extending over a plurality of areas in the shared memory area 150 corresponding to each communication definition object file) A link relationship linked by information) is established (step 411). In the process of step 411, the integrated hash table generated in step 410 is used as necessary.

The processing of the hash table integrating / linking means 104 as described above will be described with reference to FIG.

In the shared memory area 150 shown in FIG. 3, first, the hash table created for each of the communication definition sub-object files 22, 23, and 24 by the process of step 410 by the hash table integrating / linking means 104. Tables 324, 334, and 344) are integrated hash tables (table 31).
2) (the individual hash tables (tables 324, 334, and 344) in FIG. 3 are eventually deleted).

Next, by the processing of step 411, a link relationship is established between the communication definition object files (each of the communication definition main object file 21 and each of the communication definition sub-object files 22, 23, and 24). An example of a link relationship is shown in “Table 3
There is a relationship that connects the table 342 and the table 333 by the pointer to the table 333 in 42.
In this example, if the table 333 is not created before the table 342, the link relationship cannot be established. As can be seen from this example, it is necessary to perform the process of generating the link relationship that extends between the communication definition object files after all processes have completed the table expansion. Therefore, this processing is performed as the processing of step 411 by the hash table integration / linking unit 104 after it is confirmed in the determination of step 409 that “the table expansion processing of all processes has been completed normally”.

The table developing means 103 determines in step 409 that "the table developing process by all processes did not end normally (the table developing process by any process ended abnormally)" ( If the determination in step 409 is “No”, the shared memory area 150 is released (step 412).

After the processing of step 411 or 412, the processing by the communication management program startup initialization method according to the present embodiment is completed (normally or abnormally).

After the communication management program 11 is started as described above, the communication management program 11 cooperates with the communication control program 17 in the communication processing device 16 to form an online network in the network system including the LAN line 18 and the terminal 19. Do business.

In the above description, the case where the number of files in the communication definition object file group 14 in FIG. 1 is 4 (the case where the number of communication definition sub-object files is 3) has been described (see FIG. 2). However, more generally, the plurality of communication definition sub-object files in the communication definition object file group 14 include the above-described communication definition sub-object file corresponding to the communication processing device, the communication control program / line corresponding communication definition sub-object file, Not only the communication definition sub-object file corresponding to the terminal but also another communication definition sub-object file may exist. That is,
As shown in FIG. 5, the communication definition object file group 1
The number of communication definition object files in 4 is
Generally, the number is N (a positive integer of 4 or more).

As shown in FIG. 5, even when the number of communication definition object files in the communication definition object file group 14 is N (the number of communication definition sub-object files is "N-1"). , Parent process 110 (initial setting processing unit 10 in parent process 110)
0) reads “N−1” communication definition sub-object files 22, 23,..., 2N from the communication definition main object file 21 to obtain “N−1” initialization child processes. 200 (initial setting child processes 202, 203,..., 20N). As a result, each communication definition object file and each process can be assigned one-to-one, and the table development process can be executed in parallel by N processes, so that the initial setting process can be performed faster than in the related art. Can be realized.

Here, what kind of “N−1” communication definition sub-object files are present is described in “Communication Definition Sub-Object File for Communication Processing Apparatus” already mentioned in the description of FIG. In addition to the "communication control program / line correspondence communication definition sub-object file" and the "terminal correspondence communication definition sub-object file", for example, "application program correspondence communication definition sub-object file", "cross-domain correspondence communication definition sub-object file" , "Cross-domain resource definition communication definition sub-object file", and "Communication method definition communication definition sub-object file"("Cross-domain resource definition communication sub-object file" and "Cross-domain resource definition communication definition sub-object file" Bed If the object file "exists in the configuration of a managed network system of the communication manager 11, so that the host computer is more present). It is also conceivable to divide the communication definition sub-object file relating to one type of resource into a plurality of communication definition sub-object files.

As described above, according to the present invention,
It is possible to perform a high-speed initialization process at the time of starting the communication management program, and it is possible to reduce the time spent on the startup process of the communication management program.

The reason why such an effect occurs is that, in the table developing process, which is a main process of the initial setting process, if the prior art is used, all communication definition object files must be sequentially developed by a single process. In contrast to this, according to the present invention, table expansion processing is performed in parallel by a plurality of processes (in order to achieve the highest speed processing, the same number of processes as the number of communication definition object files). This can reduce the time required for the table expansion processing.
