Resource Managers

In known operating systems, resources were allocated by specific functions and when the use of the resource was terminated, the resource was made available for reuse by the system. This process can be improved by the concept of "Resource Managers".

Each Resource Manager is responsible for the control of his resource, from initialization through normal and abnormal termination of a system service. Each Resource Manager is given control during system initialization to perform specific initialization required for control of his resource. Allocation and unallocation of these resources are handled through well-defined interfaces to the Resource Managers, to provide for controlled multiusage resources. In the event of abnormal termination of a system service, recovery processing allows a Resource Manager to validate and correct data related to the control of his resource.

The major benefit provided by this concept, is that other components of the system do not have to be dependent upon the design and implementation of the control mechanism of a particular resource.

With few exceptions, only a Resource Manager builds and updates control blocks for his specific resource. This independence allows a Resource Manager greater freedom in his method of implementation, and reduces the impact which may occur as a result of a change in that implementation.

Other benefits are that Resource Managers provide a facility for controlling the usage of a resource and fo...
