Abstract
In a distributed transaction processing system of a two-phase commit scheme, a client sequentially requests all the servers to perform PHASE I processing. When all the servers complete the PHASE I processing, the client stores data indicating the completion of the processing. When an operation is restarted after a system down of a given server, the server inquires of the client whether all the servers have completed the PHASE I processing. If all the servers have completed the PHASE I processing, the server executes PHASE II processing. If not all the servers have completed the PHASE I processing, the server in which failures occur, causing abnormal system termination performs rollback processing, and the client requests other servers which have completed the PHASE I processing to perform rollback processing.
