ABSTRACT:
An apparatus for managing shared resources used in common by a plurality of computer systems connected together through a network, wherein an executable unit on a particular computer having the shared resources is arranged being divided into a first executable unit which requests the input/output processing unit in the resource managing unit that directly manages the shared resources to execute the process for inputting/outputting the shared resources in response to optional executable units, and a second executable unit which, by using an identifier for identifying the first executable unit, requests the locking processing unit in the resource managing unit to execute the process for locking the shared resources in response to other optional executable units substituting for said first executable unit. The invention further provides a method of managing system resources wherein the second executable unit in the apparatus for managing system resources constituted as described above executes the process for locking the shared resources to substitute for the process of the first executable unit, by using the identifier that identifies the process of the first executable unit.
