Abstract

PURPOSE:To attain the control an area which is occupied by a system control program in an auxiliary storage regardless of the system scale by generating a system to a main storage via a system table group used by the system control program at start of the system. CONSTITUTION:A system generating information reading means 5 reads the contents of a system generating information store file 21, and a system control program reading means 6 reads a system control program out of a system control program store file 22. Based on this read information, a system table production means 7 produces the system tables 41, 42,... 4n to a main storage 30. Then a system control program loading means 8 loads the system control program to the storage 30. A system table correspondence means 9 solves the addresses between the system table group and the system control program after the system control program is loaded and shifts the control to the system control program 40. Thus, the occupation rate of the program 40 is suppressed in an auxiliary storage.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system generation method, and particularly to a system generation method that can create an optimization environment for a system control program.

(Prior art) In the conventional system generation method, a system control program is created by a system generation program.
Stored on auxiliary storage. The system control program created here consists of a procedure division and a group of system tables used for system control.

(Problem to be Solved by the Invention) In the conventional system generation method described above, the system control program created during system generation includes a group of system tables necessary for control. , number of devices, etc.) increases, the number of system tables also increases correspondingly. As a result, the proportion of the system control program occupied on the auxiliary storage device after the system is generated increases, so the free space on the auxiliary storage device decreases and the auxiliary storage device cannot be used effectively.

(Means for Solving the Problems) A system generation method according to the present invention includes an input means for inputting system generation information at the time of system generation, and an input means for inputting system generation information at the time of system generation, and a system generation method for creating an optimization environment for a system control program. a first registration means for registering a control program; a creation means for creating a control program; a second registration means for registering the control program; and a first registration means for registering the control program. reading means for reading the contents of the control program; means for creating a system table to be used by the control program on a main memory based on the read system generated information; means for loading the control program on the main memory; A means for associating the control program with the created system table is provided.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the system generation method according to the present invention. At the time of system generation, the above-mentioned system generation input means 1, system generation information registration means 2, system control program creation means 3, system control program registration means 4, and at the time of system startup, system generation information reading means 5, control program reading means 6,
A system table creation means 7, a system control program loading means 8, and a system table correspondence means 9 are provided.

FIG. 2 is a block diagram of the configuration of this embodiment, and FIG. 3 is an explanatory diagram of the contents of the system generation information storage file created by the system generation information registration means. Multiple lengths, numbers, and the table itself (one) are registered.

The operation of this embodiment will be described below with reference to the block diagram shown in FIG. 2 and FIG. 3.

First, a system control program optimized for the system is created at the time of system generation.

Information on the operating environment of the system, connected devices, etc. is input by the system generation information input means 1 via the input device 10 .

The system generation information registration means 2 calculates the system table used by the system control program to be created based on the input information, and sets each element of the system table group in the system generation information storage file 21 on the magnetic disk 20. To go.

FIG. 3 explains the contents of the system generated information storage file 21. For example, if the tables of each element constituting the system table group have variable lengths and multiple tables are required for each, the file 21 contains the length AI of one system table A and its length AI. Data consisting of the number of repetitions A2 and the image of the system table A may be registered as a system table type required for system control.

Next, a system control program is created by the system control program creation means 3, but the system table that the system control program should have is not created here.

The system control program created by the system control program creation means 3 is stored in the system control program storage file 22 on the magnetic disk 20 by the system control program registration means 4, and the system creation is completed.

Next, the operation at system startup will be explained.

The system generation information reading means 5 reads the contents of the system generation information storage file 21, and the system control program reading means 6 reads the system control program in the system control program storage file 22. The system table creation means 7 uses the system control program reading means 6 to generate system tables 41, 42, . ...4n is created on the main memory 30.

The system table A shown in FIG. 3 corresponds to the system table 41 on the main memory 3, and the number of repetitions A2 is n.
If so, create system tables up to 4n. Similarly, system table B is created repeatedly. At the same time as creating a system table group on the main memory, the links between mutual tables are resolved at the same time.

Next, the system control program loading means 8 loads the system control program read by the system control program reading means 6 onto the main memory 30 .

When the loading is completed, the system table correspondence means 9 performs address resolution between the system table group and the system control program, and transfers control to the system control program 40 when the system control program 40 is completed.
The system startup is completed.

(Effects of the Invention) As explained above, the present invention provides system table groups used by the system control program that are created in the main memory at the time of system startup, so that the area occupied by the system control program on the auxiliary memory bag is This has the effect of suppressing this regardless of the system scale.
