Description

The present invention relates to a resource allocation system, and more particularly to a resource allocation system capable of sharing system resources between subsystems and realizing their effective use.

(B) Background of technology When a data processing system is configured with a high degree of complexity, in order to be able to provide various services to the users of the system, access to the resources that make up the system is free. It is desirable to be able to

However, conventionally, in this type of system, there are restrictions on the configuration of the subsystems that make up this system, so the above requirements can only be partially satisfied, and effective use of resources cannot be achieved.
Problems such as deterioration of service to users are left unsolved and are becoming apparent despite the sophistication and complexity of the system, and a solution to such problems is strongly demanded. It extends to.

(C) Conventional technology and problems That is, the conventional data processing system is configured with various dedicated subsystems according to the service function provided to the system user, and the subsystem has a resource allocation function. We have each independently. Therefore, the system resources are not used in the entire system, but are physically used as subsystem resources, for example, job resources, communication resources, and monitor resources as shown in FIG. Although possible, the way of sharing resources between subsystems is closed. Therefore, the available resources are limited, and even if the effective utilization rate of the resources is low, it has to be satisfied.

(D) Object of the invention The present invention was devised in view of the drawbacks of the above-described conventional methods. The purpose of the invention is to pave the way for the shared use of system resources by each subsystem and to effectively utilize the resources. It is to provide a resource allocation method to obtain.

(E) Configuration of the Invention To achieve this object, the device of the present invention comprises a plurality of subsystems, a dedicated resource dedicated to each subsystem, and a comprehensive resource shared by the plurality of subsystems. Comprehensive resource allocation means for allocating comprehensive resources based on a resource allocation request, and resource allocation based on a resource allocation request from the subsystems for the comprehensive resources. A resource allocation processing section is provided for requesting the allocation means and allocating as a dedicated resource when the allocation by the comprehensive resource allocation means fails.

(F) Embodiments of the Invention Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the present invention. In the figure, 1 is a job management subsystem, 2 is a monitor management subsystem,
3 is a communication management subsystem. Reference numeral 4 is a job management subsystem resource allocation processing unit, 5 is a monitor management subsystem resource allocation processing unit, and 6 is a communication management subsystem resource allocation processing unit. The resource allocation processing units 4, 5 and 6 of these subsystems are connected to the comprehensive resource allocation function 10, while the resource allocation function of this subsystem, for example, in the job management subsystem, the job management subsystem resource allocation function 7 is executed. Have

The comprehensive resource allocation function 10 has a job management interface 11, a monitor management interface 12, and a communication management interface 13, and these inputs are connected to the subsystem resource allocation processing units 4, 5 and 6, respectively, Their outputs are connected to the allocator 14.

Figure 2 shows a diagram of connection relationships when accessing resources. 1,2,3
Is the job management subsystem, monitor management subsystem,
In each subsystem of the communication management subsystem, 16, 17, and 18 are resource access processing units of each subsystem. The resource access processing units 16, 17, 18 of these subsystems are connected to the comprehensive resource access function 21 for resources allocated by the comprehensive resource allocation function, while the resource access function for resources of this subsystem, for example, The job management subsystem is connected to the job management subsystem resource access function 19.

Next, the resource allocation aspect of the present invention in the above-mentioned configuration will be described.

For convenience of explanation, it is assumed that a resource allocation request is issued from the job management subsystem 1. Information on the requested resource is sent from the job management subsystem 1 to the job management subsystem resource allocation processing unit 4. The information is sent from the job management subsystem resource allocation processing unit 4 to a comprehensive resource allocation function.
It is sent to 10 (step S1 in FIG. 3) and then to the allocating unit 14 via the interface 11. In the allocation unit 14, if the allocation request is for a comprehensive resource (system shared resource), the comprehensive resource is allocated, and the allocated resource information and resource management information are managed by the job management interface 11. It returns to the subsystem resource allocation processing unit 4, and the comprehensive resource allocation function ends normally (normal in step S2). When the comprehensive resource allocation function ends normally, the job management subsystem resource allocation processing unit 4 writes the comprehensive resource allocation indication "G" in the access control table 15 and returns it to the resource control table. The resource information and the resource management information are written (step S3). On the contrary, if the allocation request is for a resource other than comprehensive resources (abnormal in step S2), the original resource allocation processing of the job management subsystem is performed (step S2).
S4). At this time, if the requested resource is a job management subsystem resource, the job management subsystem resource is allocated, and at the same time, the allocation indication "J" of the job management subsystem resource is written in the access control table 15 and
Write allocation resource information. On the other hand, if the requested resource is something other than the job management subsystem resource, the abnormality processing is started.

When any of the above allocations is performed, if an access request is sent from the user and the access processing unit 16 of the job management subsystem is entered, it becomes necessary to determine the type of allocation resource. 4 proceeds to step S5, where the resource type is determined, that is, the access control table 15
Check whether the assigned display of "G" or "J" is present, and access by the comprehensive resource access method (step S7) or access by the job management subsystem resource access method according to the display. (Step S6) is performed using the information in the resource control table.

The above is the same for monitor management and communication management.

(G) Effect of the Invention As described above, according to the present invention, system resources (inclusive resources) can be placed under unified management, so that the resources can be effectively used between subsystems.

Since the function of the present invention is installed in parallel with an existing system and is called, the effect on the system can be minimized, and the effect of reducing the strike can be obtained. To be
