Abstract
An inter-system serialization control system comprising an external storage unit commonly connected to computer systems for storing, when a request for accessing a logical processing unit in the shared resources is generated from one of the computer systems, serialization management information corresponding to the logical processing unit. The logical processing unit is smaller than a volume of the shared resources. A serialization control unit is provided in each computer system, for reading, in response to a request for accessing a logical processing unit of the shared resources, the corresponding logical processing unit in the serialization management information from the external storage unit and for accessing the corresponding logical processing unit in the shared resources under serialization control based on the read serialization management information. Whereby the serialization control is effected with a logical processing unit smaller than a volume and without inter-communicating among the computer systems so that the overhead for each CPU is reduced.
