Abstract

PURPOSE:To improve the use efficiency of memory resources by storing system constants of a computer system in a main storage device in accordance with the actual operation scale at the time of IPL (initial program load). CONSTITUTION:System constants to set and control the operational environment of the system are classified in accordance with functions and the scale of the system and are stored in a system constant file 7. When a system constant stored in the file 7 is designated from an input device 4 in the setting processing of the system constant to be used for operation of the computer system, a constant setting part 1 registers the address of the system constant in a constant index part 5. A constant processing part 2 reads out the system constant from the file based on address information registered in the constant index part 5 at the time of IPL and stores it in a system constant area 6 of a storage device 3. Thus, the system constant adapted to the configuration scale to be used for operation can be stored in the main storage device at the time of IPL, and the use efficiency of the main storage device is improved.

[Industrial application field]

The present invention provides system constants (environmental control information) necessary for system operation at the time of initial program loading (referred to as IPL) of a computer system.
In the method of deploying data to the main memory during PL, a problem arises in that as the configuration size of the computer system increases, the area of the main memory occupied by system constants increases in proportion to the configuration size.

By storing only essential system constants in the main memory according to the actual operating scale of the computer system, the efficiency of memory resource use is improved.

[Conventional technology]

FIG. 3 is a conventional system configuration diagram.

In this figure, a secondary storage device 63 holds all system constants related to the system configuration of the computer system as system constants 62, and a constant expansion unit 8 stores IPL
When a request is received, the system constant 62 is expanded and stored in the system constant area 61 of the storage device 3. As the configuration scale of a computer system expands, the system constants 62 increase in proportion to the scale, and the system constant area 61 of the storage device 3 required during IPL increases, creating a problem in securing a sufficient program execution area. .

[Problem to be solved by the invention]

The operation of a computer system starts during IPL when system constants (environmental control information) necessary for system execution are stored from the secondary storage device to a specific area of the main storage device. All system constants corresponding to the scale of the system configuration installed in the system are expanded and stored in the main memory, so as the configuration scale of the computer system increases, the area of the main memory occupied by the system constants increases. It was causing problems. The present invention aims to improve the efficiency of using memory resources by storing system constants during IPL in a main storage device in accordance with the operating scale of a computer system.

The system operates with a processing system equipped with memory and an input/output system connected to the processing system, and in step 91, system constants for setting and controlling the operating environment of the system are classified according to the function and scale of the system. The system constants are stored in the system constant file 7, and in step 92, the range of the system constants determined by the system scale is input into the constant setting section 1. In step 93, the system constants in the corresponding range are searched from the system constant file 7, and the system constants are stored in the system constant file 7. The storage address of the constant file 7 is stored in the constant index section 5, and when the system is operated in step 94, the constant processing section 2 reads the system constant from the system constant file 7 using the storage address read from the constant index section 5. , stored in the system constant area 6 of the processing system.

[Function] According to this method, the constant setting section 1 sets the system constants used in the computer system as IPL addresses in the constant index section 5 in advance, so that the system constants used in the computer system can be adjusted according to the configuration scale for special use by the computer system. It becomes possible to expand the system constants to the storage device 3, and it is possible to improve the usage efficiency of the main storage device memory resources in IPL.
