Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system editing processing method for editing necessary monitor programs and the like according to the system configuration in a data processing system.

[Problems to be solved by conventional technology and invention]

In data processing systems, changes are often made to the system configuration, such as adding or changing input/output devices or terminal equipment, and at that time, control programs such as monitor programs and firmware must also be changed accordingly.

Conventionally, as a method for dealing with such changes in system configuration, the control program is modularized for each device or function in advance, as shown at 21 in Figure 2, and the control program is modularized in accordance with the changed system configuration. A so-called system editing processing method in which necessary modules are selected, edited, and stored again in the system's disk device 22, etc., and a system configuration that takes into account devices to be connected in the future or functions to be added are defined in advance. There was a problem with the method.

However, in the case of the former method, the system editing process takes time, and is usually performed every IPL, which slows down the system start-up.Also, if the re-edited system is larger than the previous system, the system storage area is Saving/restoring processing was required for the provided data area. In the case of the latter method, there is waste in securing memory areas to implement reserved devices and functions even though they are not actually used. There was no guarantee that the system would be changed.

[Means for solving problems]

The present invention stores a system configuration management block that indicates the system configuration and a control block that has information for selecting modules necessary for configuring the system in the system area, and makes it possible to change the system configuration. In this case, perform system change processing on the system configuration management block and perform the following steps.
A system of control programs (firmware, monitor) that matches the system configuration changed by IPL is generated in the editing result storage area of the same system area, and its configuration is based on the system configuration management block that shows the system configuration. A system area is provided on external storage including a plurality of control modules related to system components, a control block indicating the correspondence between each control module and the system components, and a system editing result storage area, and the system configuration is When changing the contents of the system configuration management block, execute an IPL while changing the contents of the system configuration management block, refer to the control block in the IPL based on the contents of the changed system configuration management block, and select the necessary control module. The present invention is characterized in that the system is edited and stored in the system editing result storage area, and in subsequent IPL, the system of the edited control module stored in the system editing result storage area is to be loaded.

〔Example〕

The details of the present invention will be explained below with reference to Examples.

FIG. 1 is a conceptual diagram of one embodiment of the system of the present invention. In the figure, 1 is a disk device, 2 is a system configuration management block, 3 is a control block, 4 is a group of modules to be selected, 5 is an editing result storage area, and 6 is an installation program.

To explain the general operation, as shown in FIG. 3, the system configuration management block 2 refers to the control block 3 based on the equipment and functions that make up the system, and selects suitable modules from the selection target module group 4. Select, edit, and store in the editing result storage area 5. When a system change request occurs, the contents of the system configuration management block 2 are rewritten by the installation program 6. Then, at the next IDL, the contents of the editing result storage area 5 are correspondingly updated, and from then on, the contents are kept fixed until further changes are made to the system configuration. That is, the modules from the system configuration management block 2 to the selected module group 4 are stored in the system storage area 3 as shown in FIG.
1 and remains unchanged after being edited.

System configuration management block 2 is a table that displays the device configuration and functions of the current system.
For example, as shown in Figure 5, online configuration such as monitor functions, system information such as the number of frames (job control number) and buffer number, input/output device I/O configuration, workstation WS configuration, communication control procedure, etc. Contains.

As shown in FIG. 6, the control block 3 includes, for each module in the selection target module group 4, module selection information indicating the module name and the input/output device I/O, monitor function, etc. to which this module is applied. I'm here. For example, in the case of a certain printer control module, a flag indicates that it should be selected only when a Kanji printer and a line printer are used.

The selection target module group 4 includes all modules associated with equipment and functions that can be used by the system.

Next, the operation of this embodiment will be explained using a specific example shown in FIG. Figure a shows the current system configuration,
It is shown that the system consists of a display device A, a floppy device B, a disk device C, and a printer device D. FIG. b shows that a display device E and a printer device F have been added. Note that A, B, C..., J,... represent device names. Diagram c shows module names A○, B○, C○, ...,
A selection target module group consisting of modules J○, . . . is shown. Here, module names A○, B○,
C○, ..., J○, ... are device names A, B, C, respectively.
. . , J, . . . represent the module to be selected when the devices are used. FIG. d shows the contents of the system configuration management block and editing result storage area corresponding to the system configuration of FIG. a. Figure e shows the contents of the system configuration management block and editing result storage area when the device shown in Figure b is added to the system configuration of Figure A.

The steps until the system is re-edited are as follows.

The device name to be added is added to the system configuration management block 2 shown in FIG. 5 using the installation program. As a result, the contents of the system configuration management block 2 are as shown in d to e in FIG. 7.

At IPL immediately after the change, the changed system configuration management block 2 and control block 3 are compared, and the module names A○, B○, C○, D○, E○, F required for the system are determined. Decide ○.

The above module name required by the system A○,
B○, C○, D○, E○, F○ are selected module group 4
The monitor is extracted from among them, edited (linked), and the obtained monitor is stored in the editing result storage area 5.
As a result, the shape shown in FIG. 7e is obtained.

The monitor stored in the editing result storage area 5 is loaded and developed on a memory (not shown). After that, control is passed to the monitor and operation becomes possible.

In addition, in the subsequent normal IPL (IPL when system changes are not involved), the above operations are not necessary, and only the operations are performed.
IPL is expedited.

FIG. 8 shows the flow of the above-mentioned IPL. That is, first determine whether system editing is necessary, and if necessary, perform system editing. If it is not necessary, system editing is not performed, and the already edited monitor is loaded onto the memory from the editing result storage area 5.

〔Effect of the invention〕

According to the present invention, there is no need for system editing or re-storage processing, so quick system changes can be made at the system installation location, and normal
Since no system editing is performed during IPL, start-up is faster, the system area occupied in memory is constantly optimized, and the data area is guaranteed because the system does not need to be re-stored.
