PROBLEM TO BE SOLVED: To provide a system of multiple hot-standby and fault tolerance method. SOLUTION: The system of multiple hot-standby and fault tolerance method detect and monitor a plurality of application servers with a plurality of serial backup servers, connect all application servers in parallel by the backup servers, and detect other backup servers mutually. When application server errors occur, an abnormal heart rate signal is detected, a backup server directly connected immediately substitutes the application server of the error and, at the same time, another backup server connected with this backup server is substituted for the original backup server, and continues to detect and monitor all the application servers. Thus, programs and jobs in the application servers are not interrupted, and high fault tolerance capabilities are achieved with a fewer backup servers. COPYRIGHT: (C)2008,JPO&INPIT
