DEVICE AND METHOD FOR PROCESSING MERGE REQUEST RECEIVED BY MEMBER IN GROUP IN CLUSTERED COMPUTER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an improved method for executing merging operation to connect many partitions in a clustered computer system, its device, and a program product and a medium which holds the program product. SOLUTION: The device, program product, and method for executing the merging operation use messages sequenced by the clustered computer system to shift the execution of a merging protocol in a clustered group by generally guaranteeing the cancellation or completion of each holding program prior to the execution of the merging protocol until all holding protocols of respective partitions in the group are executed. From the point of view of each group member, the execution of the merging protocols is changed by impeding the processing of a merging request by such a member after all precedent reception requests which are being held are processed.
