MULTICOMPUTER SYSTEM, COMMUNICATION PROCESSOR, TRANSACTION PROCESSING SYSTEM, METHOD FOR TRANSFERRING OPERATION OF TRANSACTION PROCESSING SYSTEM, AND RECORDING MEDIUM RECORDING TRANSACTION PROCESSING SYSTEM OPERATION TRANSFERRING PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent a message untransacted after receiving it from being disused at the time of restarting a transaction processing system even when all transaction processing systems in a rough connection system run down. ;SOLUTION: When a transaction processing system or a host computer 1a runs down, its host pass 51 is disconnected but the other transaction processing system 10b succeeds the state by using a shared file 3. When all systems run down, all host passes 51 are disconnected but a recovery monitoring means 42 on a communication processor 4 waits until the host passes 51 are reconnected while holding a terminal pass 61, restarts the systems so as to continue preceding operation, so that the host passes 51 are reconnected and operation is continued without initializing the file 3.;COPYRIGHT: (C)1999,JPO
