METHOD, SYSTEM, AND PROGRAM PRODUCT FOR MANAGING PROCESS GROUP IN DECENTRALIZED COMPUTING ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To easily manage and use a copied distributed transaction. SOLUTION: A distributed synchronous transaction system protocol is provided and a duplication of a distributed transaction of a client application instance is managed. The distributed synchronous transaction system enables the client application instance to duplicate a transaction without being aware of other instances so as to receive the transaction. Further, if trouble occurs during the processing of a duplicated transaction of a distribution system, the distributed synchronous transaction system manages recovery from the trouble.
