Abstract

PURPOSE:To improve maintainability and to reduce cost by performing the generation and update of a system file by copying only a desired object module from the object modules prepared corresponding to each program module with a file control means based on information in a data base. CONSTITUTION:The data base 8 holds the information of a program required by a system and that of a changed program. A file control program 9 performs the control of the source modules 1, 2, the object modules 5, 6, and the data base 8, and also, performs the generation and update of the object module 7 of the system file by referring to the data base 8 corresponding to the request of the generation and update of the system file. Thereby, an operator can be released from complicated work.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automatic system file creation method in an electronic exchange system controlled by a storage program. [Prior Art] A system file used in a storage program controlled electronic switching system requires functions common to the same type of system and functions specific to the station to which the electronic switching system is applied. A system file is created by combining a program selected according to system conditions from a base system file that collects multiple programs related to various functions with a program from a program file prepared according to station conditions. In addition, multiple programs related to basic functions are collected in the mother system file,
The reason why you select the programs you will need from now on is to increase the versatility of creating system files. FIG. 3 shows the process of creating a system file in the conventional system. Source module 1 of program A included in source module 1 of the parent system file
1 and program B, and source module 21 of program D included in source module 2 of the program file are necessary for creating the system file, source modules 11, 12 .
21 to create a system file source module 3 containing source modules 31, 32, and 33.
Thereafter, by compiling this source module 3, an object module 4 of the system file including object modules 41, 42, and 43 was created. [Problem to be solved by the invention] Conventionally, system files (object modules) have been created as described above, and program files prepared according to the unique functions of the stations used in the electronic exchange system. In addition to preparing the source module, the source module of the parent system file can be used in common, making it highly versatile, but it had the following drawbacks in terms of maintainability and cost. ■Creating a system file (or creating a new file) is complicated because the operator must be aware of the programs required by the system when merging files. ■If a change occurs in a part of the program, the process must be merged again, making maintenance complicated. ■For programs that use system files, there are two source modules, and both must be saved, which is wasteful. ■Overall, there are problems in terms of maintainability and cost.

The present invention has been proposed in view of the above points, and its purpose is to create and update system files easily, improve maintainability, and reduce costs. The purpose is to provide a certain method of operation. [Means for Solving the Problems] In order to achieve the above object, the present invention combines a program selected from a parent system file according to system conditions and a program from a program file prepared according to station conditions. In this method, a system file for an electronic exchange system is created using a database that holds information on programs required by the system and programs that have been changed, and an object module prepared corresponding to the source module of each program. It is equipped with a file management means that copies only what is necessary based on the information in the database and creates and updates system files. [Operation] In the system file automatic creation method of the present invention, the database holds information on programs required by the system and programs that have been changed, and the file management means stores the source of each program based on the information in the database. Create and update system files by copying only what is necessary from the object modules prepared for each module. [Examples] Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a structural diagram showing an embodiment of the system file automatic creation method of the present invention. In FIG. 1, l is a source module of a parent system file, and programs A, B. Contains the C source module 1l12.13. 2 is a source module of program files, and includes a source module 2l of program D having a function specific to the station. Also, object modules corresponding to source module 1.2, that is, programs A, B, and C.
An object module 5 of the parent system file including the object modules 51, 52, 53 of , and an object module 6 of the program file including the object module 6l of the program D are created before the system file is created. On the other hand, 8 is a database that holds information on programs required by the system and programs that have been changed. Further, 9 is a file management program (file management means), and source modules 1, 2 . It manages the object module 5.6 and the database 8, and also has the function of creating and updating the object module 7 of the system file by referring to the database 8 in response to requests for creating and updating system files. The operation is explained below. (1) When creating a new system file When an operator or the like requests creation of a system file, the file management program 9 refers to the information 8l in the database 8 indicating the programs required by the current system. In the diagram, “O
Programs A, B, and D with "" are necessary for the system file to be created, and program C with "x" is not necessary for creating the system file. File management program 9 is information 81 of database 8
Accordingly, the object module 5l of program A and the object module 52 of program B are extracted from the object module 5 of the parent system file, and the object module 6l of program D is extracted from the object module 6 of the program file,
Copy them into object modules for programs A, B, and D? Create object module 7 of the system file containing 1, 72, and 73. This creates a system file object module that can be executed on a computer. (2) When updating system files First, when a change occurs in any of the programs that make up the system file, the source module of that program is changed, the corresponding object module is also changed, and information about the change is changed. is stored in database 8. For example, as shown in FIG. 2, when a change occurs in the source module 11 of program A included in the source module 1 of the parent system file, the change is made to the source module 1l, and the change is made to the source module 1l of the parent system file. The corresponding object module 5l of the object module 5 is also changed, and this fact is stored by the file management program 9 as information 82 indicating the changed program in the database 8. In the figure, "☆" indicates programs that have been changed. When there is a request from an operator or the like to update a system file, the file management program 9 retrieves information 82 from the database 8 indicating programs that have been changed regarding the system.
Refer to. Then, for the changed program A, the object module 51 of the program A is extracted from the object module 5 of the parent system file, and is copied to the object module 7 of the system file to replace the previous object module 71.
This completes the update of the system file object module 7.

Regarding the means for realizing each management information of the database 8 and the file management program 9, it is necessary to consider methods that correspond to the various system architectures of each support system, but in any case, this The effects of inventions remain the same. [Effects of the Invention] As explained above, in the system file automatic creation method of the present invention, ■ System files are automatically created and updated based on the information stored in the database, so the operator does not have to worry about the hassle. Freed from heavy work. ■There is no waste because there are no duplicate source modules. ■Overall, problems in terms of maintainability and cost are resolved. It has the following effects.
