Description

System and method for controlling resources used by services

【Technical field】

The invention relates to a system and method for controlling resources used by services.

【Background technique】

There are many resources in the computer system, and the corresponding computer system also provides many services for users to use, and these services must also use corresponding resources. In the absence of control, each service only knows its own use of each resource, but cannot know the use of each resource by other services. In some cases, because a service is doing special work on a resource, another service will use the same resource to produce unpredictable results. For example, service B is formatting hard disk A, and another service C is also trying to read data from hard disk A, so service C will produce unpredictable results. To avoid this, a system is needed to govern the resources used by services.

China Taiwan Intellectual Property Bureau announced on June 21, 2004 that the announcement number is 594491, and the invention patent titled "Technology for Identifying Resource Requests in Computer Systems" discloses a method for identifying resources that include a resource controller. A method for making requests in a data processing system with a bus. Its shortcoming is that it can only verify the rationality of service requests, and cannot further resolve conflicts when reasonable services use the same resource.

【Content of invention】

The main purpose of the present invention is to provide a system for controlling and managing resources used by services, which can judge resource usage status and avoid conflicts between services when using resources.

Another object of the present invention is to provide a method for controlling resources used by services, which can determine resource usage status and avoid resource conflicts between services.

To achieve the above object, the present invention provides a system for controlling resources used by services. The system for controlling resources used by services includes a central processing unit, an operating system, a bus, a control system, and resources used by the system. Wherein, the control system includes a resource license list and an arbitration module. The resource license list is stored in the storage resources of the system and manages the licenses of each resource. The arbitration module is used to check whether the license of a resource required by a service has been taken away to determine whether the service can obtain a resource license. When a service can acquire resource licenses, it acquires the required resource licenses for the service to run the service. The resources used by the system also include storage resources, I/O (Input/Output, input/output) resources, and communication resources. Storage resources include all available storage media in the system. resources.

The present invention also provides a method for using the above-mentioned system to control and manage resources used by services, which includes the following steps: when a service requests to use resources, start the control and management system, and check the occupancy of the resources to determine whether the service can obtain a license for the resource ; If the resource license can be obtained, obtain the resource license for the service to run the service; return the used resource license when the resource is used up; end the service. If the service cannot obtain the resource license, the license will not be granted and the service will end.

The system and method for controlling and managing resources used by services in the present invention can judge whether a service can use various resources according to the resource license list. The design is simple, requiring less processing time and occupying less storage space.

【Detailed ways】

As shown in FIG. 1 , it is a system architecture diagram of the system for controlling and managing resources used by services in the present invention. The system for controlling resources used by services includes a CPU 10 , an operating system 11 , a bus 12 , a control system 13 and resources 17 used by the system. Wherein, the control system 13 includes a resource license list 131 and an arbitration module 132 . The resource license list 131 is stored in the storage resource 14 of the system, and manages the license of each resource. The arbitration module 132 is used to determine whether the service can obtain a license. The resources 17 include storage resources 14, I/O (Input and Output, input/output) resources 15 and communication resources 16. The storage resource 14 includes all available storage media of the system, and the communication resource 16 includes various resources required for the system to communicate with various types of network connections.

As shown in FIG. 2 , it is a flow chart of the method for controlling and managing resources used by services in the present invention. When a service requests to use a certain resource, the control system 13 is started (step S200), and the arbitration module 132 checks the occupancy of the resource to determine whether the service can obtain a license for the resource (step S201), if the license for the resource can be obtained License is then given permission to run the service (step S202), and then the license to use the resource is returned after the resource is used (step S203), and the service is terminated (step S204). If the service cannot obtain the resource license, a warning message is issued (step S205), and the service is terminated (step S204).

As shown in FIG. 3 , it is a schematic diagram of a resource license list of the system for controlling resources used by services in the present invention. Each bit represents a license of a resource. When a bit is 0, it indicates that the corresponding resource is not used by the service. When a bit is 1, it indicates that the license of the corresponding resource has been taken away.

As shown in FIG. 4 , it is a flowchart of the license acquisition operation of the method for controlling and managing resources used by services in the present invention. First, the arbitration module 132 obtains the resource license list 131 (step S300), checks whether the license of the required resource has been taken away (step S301), if the license of the resource has not been taken away, then the resource is listed in the resource The corresponding bit in the license list 131 is set to 1 (step S302), the resource license list 131 is released (step S303), and the fax value indicates that the service has obtained the license (step S304). If the license of the resource has been requested, a false value is returned, indicating that the service has not obtained the license (step S305).
