[0002]

2. Description of the Related Art Conventionally, it has not been verified at the time of job execution whether or not a program is a correct execution program. In particular, if there are many libraries for storing executable programs, such as for testing and production,
The actual situation is that the operator is conscious of which execution program storage library to use when creating a job control statement.

[0003] Also, Japanese Patent No. 2602205 discloses a "database access control method" in which "when the load module is executed, generation information of first definition information embedded at the time of compiling and stored in the directory. Check if the generation information of the second definition information at the time of execution of the load module matches,...
A database access control method characterized by performing error processing if they do not match. (From claim 1). Further, according to the present invention, "according to the present invention, in a database system having a data dictionary directory function, when compiling an application program, by referring to definition information in the dictionary ... Performing the processing in advance reduces the amount of processing at the time of execution and improves execution performance. "
(From the effect of the invention). This is because "The runtime management table (having the generation number) is checked for a matching directory, and if there is a matching directory, the database management program uses that directory. It is guaranteed that the directory will be used after the consistency of the directory at the time of execution of the application program is checked. "(From page 11, column 6, column 11).

FIG. 2 is a schematic configuration diagram showing the configuration of this conventional example. In FIG. 2, (26) is a database system management program for performing database access (storage, retrieval, updating, etc.) and message transmission / reception with the terminal, (2)
7) is a database, (28) is a terminal, (29) is a dictionary file in which the definition information of the database is registered in a source format, and (30) is edited from the dictionary into a format that can be easily referred to when the database system management program is executed. A directory generation program for generating definition information (directory table) of the database system, and (31) is a directory file for registering the directory table.
