As a preparation for the dynamic change, the system generation mechanism 15 of the configuration management program 2 on an arbitrary system 1 is prepared in advance.
Thus, the difference data 6 is created. The difference data 6 may be created any time before the dynamic change is executed.

The dynamic change is executed by the system change mechanism 16 of the configuration management program 2 on the arbitrary system 1.

The input / output configuration reference table 7 before the dynamic change is shown in FIG. At this time, the input / output device 7a to be deleted or changed can be used by all the systems 1.

The input / output device availability setting means 16c disables the input / output device 7a to be deleted or changed on the input / output configuration reference table 7. As a result, the input / output device 7a to be deleted or changed becomes unusable from all the systems 1 [FIG. 7 (b)].

The input / output device information section changing means 16d and the input / output apparatus connection information section changing means 16e change the input / output configuration reference table 7 based on the difference data 6. At this time, the added or changed input / output device 7b is disabled on the input / output configuration table 7 and cannot be used by all the systems 1 [FIG. 7 (c)].

Thereafter, the system dynamic change end contact means 1
6f indicates that the added or changed input / output device 7b can be used on the input / output configuration reference table 7 [FIG. 7 (d)],
Notify all systems of the end of dynamic changes. After that, all systems can use the input / output device by using the changed input / output configuration reference table 7.

When an I / O device and a system are added by the above-described system dynamic change process, the added I / O device becomes usable by the end of the above process, and the added system starts up. Can be raised.

According to the above-described embodiment of the present invention, in a complex system composed of a plurality of computer systems,
Regardless of shared and non-shared I / O devices, it is possible to define the I / O device configuration from any system at once, and it is necessary to define the shared I / O devices redundantly between the systems. Since it does not exist, the system generation work can be performed only once without depending on the number of systems, and the system generation efficiency can be improved.

Further, according to one embodiment of the present invention, an input / output configuration reference table converted into a format to be referred to when executing data input / output to / from an input / output device is converted from the input / output configuration definition table when an arbitrary system is started. Since it is read and placed in the shared memory so that it can be referenced by all systems, it is not necessary to read the I / O configuration definition table when starting another system, and the system startup time can be shortened.

Further, according to one embodiment of the present invention, the input / output configuration definition table and the input / output configuration reference table are configured by arranging the input / output device information section and the input / output apparatus connection information section in a matrix format. Therefore, it is possible to easily add, delete, or change the input / output device and the system without limitation, and it is possible to improve the flexibility in the system configuration.

Claims (4)

[Claims] 1. In an input / output device information management system of a complex system composed of a plurality of computer systems, each computer system has an input / output configuration definition table that defines the configuration of all I / O devices used in the complex system. One input file is provided on the shared file that can be referred to when the system is started up. The I / O configuration definition table defines the I / O device type, attribute information, etc. necessary for executing data I / O to the I / O device. An input / output device of a complex system, which is configured by arranging an output device information section and an input / output apparatus connection information section that defines a connection relationship between each input / output apparatus and each system in a matrix format. Information management system. 2. The computer system according to claim 1, wherein each computer system can refer to the input / output configuration reference table obtained by reading the input / output configuration definition table and converting it into a format that can be referred to when executing data input / output to / from an input / output device. One input / output configuration reference table is provided in the shared memory, and the input / output configuration reference table defines an input / output device information section that defines the type of input / output device, attribute information, etc. necessary for executing data input / output to / from the input / output device, and each input / output device reference table. An input / output device information management system for a complex system, comprising an input / output device connection information section defining a connection relationship between an output device and each system arranged in a matrix format. 3. The mechanism according to claim 2, which updates the input / output configuration definition table on the shared file and the input / output configuration reference table on the shared memory from any one of the computer systems, and a composite of each update content. A mechanism for notifying another computer system in the system is further provided, and a part of the information is input to the input / output device information section and the input / output device connection information section in the input / output configuration definition table and the input / output configuration reference table. An input / output device information management system for a complex system, which adds, deletes, or changes the I / O devices used in the complex system in a batch while the complex system is operating. . 4. A system for updating an input / output configuration definition table on a shared file and an input / output configuration reference table on a shared memory from any one of the computer systems according to claim 2, By further providing a mechanism for notifying other computer systems in the input / output configuration definition table and the input / output configuration reference table, by adding, deleting and changing a part of the information. An input / output device information management system for a complex system, wherein the addition, deletion, or modification of the computer systems that compose the complex system is collectively executed while the complex system is operating.
