Abstract

PURPOSE:To control and set automatically the working environment of an OS in response to the operating situation of the OS, by defining the larger one of both values obtained by multiplying the maximum recorded value by a prescribed margin factor set previously and the value set on a resources control table as the allocated value of the system resources to the OS. CONSTITUTION:A start means 2 first refers to the log data 5 when an operating system OS1 is started and checks the maximum value so far used for each of various system resources 10 to multiply this maximum application value by a margin factor set previously. Then the value thus obtained is compared with the set value on a resources control table 3 and the larger one of both values is defined as the application area of the OS1. Thus a new working program, for example, works and the work area of the OS1 is increased. While the margin of the system resources allocated to the OS1 is reduced. Thus the resources 10 are allocated to the OS1 in consideration of situations despite such fluctuations of the system operating state. In such a way such an unexpected case where the system working is stopped due to insufficiency of resources can be prevented.

Description

[Detailed Description of the Invention] [Summary] When collecting log data of the system resource usage status of the operating system (hereinafter abbreviated as O3) and allocating system resources to O8 at the time of system startup, the startup means A value obtained by multiplying the maximum value of the log data by a predetermined margin rate is compared with a value set in the resource management table, and system resources are allocated to O8 according to the larger value.

[Industrial application field]

The present invention relates to a system resource management method that can automatically change the allocation of system resources to an operating system according to the actual situation.

[Conventional technology]

The basic operating system (hereinafter abbreviated as O3) that runs a computer is the
8 requires system resources to operate.

The area used by O3 on this system resource is set at the time of system editing and managed by the system operations manager.

However, once the system actually starts operating, the usage area of O8 changes dynamically. In other words, as more tasks are added, more system resources are needed, but the allocation of system resources cannot be changed dynamically, and the only option is to wait for the system operations manager to manually change the settings.

If the system is operated without changing the allocation of system resources even though the actual usage area of O8 has changed, there is a risk that one day the system will suddenly become inoperable due to lack of resources and the system will stop.

[Problems to be solved by the invention] As mentioned above, in an operating computer system, the system resources used by O8 change dynamically, but the allocation of system resources cannot change dynamically, and the actual There was a problem in that it could not keep up with usage conditions.

The purpose of the present invention is to
The purpose of the present invention is to automatically manage and set the operating environment of the computer.

[Means for solving problems]

The present invention provides a resource management means, which records the usage status of various system resources of O8 during system operation,
When allocating system resources to O3 at system startup, the amount of system resources allocated to O8 is determined by the larger of the maximum value in the above record multiplied by a predetermined margin rate and the value set on the resource management table. It was configured so that

[For production]

When the system is started, system resources equal to or greater than the maximum amount of system resource usage of the O8 up to that point plus a predetermined margin are allocated to the O8.

Therefore, it is possible to allocate resources in consideration of changes in the system operating state.

〔Example〕

FIG. 1 is an explanatory diagram of the configuration of the present invention, in which the OSI is a main storage device 6. Auxiliary storage devices such as direct access volumes (DASD) 8. It controls the execution of various running programs while managing various system resources 10 such as the virtual storage device 9.

OSI uses various system resources 10 during system operation. Therefore, when editing the system, OSI.

The amount of various system resources 10 to be allocated to is set and registered in the resource management table 10. If this value needs to be changed, the system administrator can manually reset it; conventionally, no other changes have been made.

The activation means 2 refers to the resource management table 10 and
Various system resources 10 are allocated to si and the system is started. In the figure, the shaded portion of the system resource 10 indicates the area allocated to the OSI.

The user program 11 uses the remaining portion of the system resources 10 in running.

In addition to the above configuration, the present invention provides 031 during system operation.
A resource management means 4 is provided for collecting log data 5 of the system resource usage status.

An embodiment of the present invention having such a configuration will be described below with reference to the drawings.

FIG. 2 is a diagram showing the system in operation. The user program 5 runs while using the main storage device 6, DASD 8, virtual storage device 9, etc. while interacting with the console 7 as necessary.

During this time, O3I also uses various system resources 10 to perform resource management, job management, and data management. Note that the shaded areas in the figure represent each system resource 6.8.
9 shows the area actually used by O81.

The usage status of the system resources 10 in 031 is collected and recorded as log data for each system resource 6, 8, and 9 by the resource management means 4. The path of the data is shown by a dotted line.

This operation may be performed all the time while the system is in operation, or may be performed as necessary when there is some change in system operation, such as when a new job is submitted.

FIG. 3 is a diagram showing a state in which the startup means 2 starts up the system using the log data 5 described above.

When starting the system, the startup means 2 first uses the log data 5.
, the maximum usage amount up to now for each type of system resource 10 is checked, and this value is multiplied by a preset margin rate. The values obtained in this way and the resource management table 3
, and the larger value is assigned as the usage area of O81. The dotted line shows the path of this operation, and the shaded area shows the allocated area. The above margin rate is
The information is set in the resource management table 3 in advance by the system operations manager.

By referring to the log data 5 and allocating the system resources 10 to the OSI in this way,
For example, even if the operating status of the system changes, such as when a new business program starts running, the work area used by OSI increases, or the system resources allocated to O81 decreases, the situation should be taken into account. System resources 10 will be allocated to OSI.

Therefore, according to this embodiment, it is possible to dynamically change the allocation of system resources 10 to OSI according to the operational status of the system, thereby preventing unexpected situations where the system stops due to resource shortage. .

As the log data 5, only the maximum value up to now is recorded, and the value collected by the resource management means 4 is the log data 5.
The log data 5 may be rewritten only when the value is larger than the value.

Furthermore, if it becomes necessary to make the allocation of the system resources 10 to the O81 described above different from the values in the resource management table 3, in other words, the value of the maximum value of the log data 5 plus the predetermined margin will be the resource allocation value. When the set value of the management table 3 is exceeded, the set value of the resource management table 3 may be automatically rewritten.

〔Effect of the invention〕

As explained above, according to the present invention, the operating environment of the system can be automatically changed, the system will not stop as long as there are physical resources, and the system environment can be set to suit the operating status of the system. .
