<p>PROBLEM TO BE SOLVED: To solve a problem that the conventional hot standby system has a limit to shorten failure detecting time since it detects the failure by interruption of heartbeat. SOLUTION: In this computer system constituted by providing and multiplexing a plurality of computers to be operated as switching a plurality of operating systems, the respective computers 10, 11 have a plurality of OSs under an OS switching program, monitors a software failure of an application OS 510 by a monitoring OS 520 and when the failure is generated, immediately informs other system of the failure via an exclusive communication means from an inter-system monitoring task 522. Handover time is shortened since the failure is detected without waiting for the interruption of the heartbeat.</p> |
