As shown in FIG. 1, the network control information storage file creation method 1 of the present invention is comprised of a network control information creation means 11, a file capacity calculation means 12, and a network control information storage file creation means 13.

The network control information creation means 11 generates online environment definition information 2 from the online environment definition information storage file 2.
1 is read, network control information 411 is extracted from the online environment definition information 21, and stored in the storage area 41 of the operating system 4.

Next, the file capacity calculation means 12 calculates the network control information 4 stored in the storage area 41 of the operating system 4 by the network control information creation means 11.
11, calculates the file capacity 412 of the network control information storage file 3 used by the network management program, and stores this in the storage area 41 of the operating system 4. Next, the network control information storage file creation means 13 reads the file capacity 412 stored by the file capacity calculation means 12 from the storage area 41 of the operating system 4, and then compares the file capacity 412 with the network control information storage file 3. The file creation function 42 of the operating system 4 is started by specifying the organization information, and the network control information storage file 3 used by the network management program is created.

Next, an example of the online environment definition information storage file 2 will be briefly described with reference to FIG. In the online environment definition information storage file 2, online environment definition information 21 is stored in groups of codes for each communication processing control device name.

An example of the online environment definition information 21 will be briefly explained with reference to FIG. The online environment definition information 21 is composed of names of devices constituting the network, such as communication processing control device names, line names, terminal control device names, and terminal device names.

Next, referring to FIG. 4, the network control information 411
Let's briefly explain an example. The network control information 411 is composed of the number of communication processing control devices, the number of lines, the number of terminal control devices, and the number of terminal devices.

Next, with reference to FIG. 5, the operation of the network control information creation means 11 in the network control information storage file creation method 1 of the present invention will be described.

First, the online environment definition information storage file 2 is opened (step 51), and the online environment definition information 21 is read (step 52). Extract network-related information consisting of communication processing control device name, line name, terminal control device name, and terminal name from the read online environment definition information 21 (Step 53), and calculate the number of devices from the multiple device names for each item. , and writes this into the storage area 41 of the operating system 4 as network control information 411 (step 54). Repeat this for each chord,
After reading all the records (step 55), the online environment definition information storage file 2 is closed (step 56).

Next, referring to FIG. 6, file capacity calculation means 1 in network control information storage file creation method 1 of the present invention.
The second operation will be explained. Network control information 411 written in the storage area 41 of the operating system 4
are read (step 61), each value is multiplied by each predetermined number of digits, and this sum is multiplied by the margin rate to calculate the file capacity 412 (step 62). Write the calculated file size 412 to the storage area 41 of the operating system 4 (step 63
).

Step 74): Create a network control information storage file 3 to be used by the network management program.

〔Effect of the invention〕

As explained above, the present invention uses network control information created based on online environment definition information read from the online environment definition information storage file to reduce the file size of the network control information storage file used by the network management program. After calculation, by creating a network control information storage file based on the calculated file size, it is possible to create a file with a file size suitable for the amount of network control information of the system, thereby reducing manual errors.
