PURPOSE:To monitor an operating state of a system, while operating its system and to execute a cause analysis and a recovery processing by on-line at the time when abnormality has been generated by providing an exclusive operation processor for executing only a monitor control of the system and storing a monitor program in an area of a main storage device. CONSTITUTION:A monitor program is started at a time interval which has been determined in advance at every monitor program by using a monitor 20, and an executing state of an execution program corresponding to the started program is monitored by a monitor operation processor 2 which has been connected to a main storage device 3. When abnormality has been detected, the cause is analyzed, and if it can be recovered, a recovery processing is performed, and when no abnormality is detected, regular monitoring is executed continuously. In such a way, when abnormality has been generated, the system is recovered by operating only the monitor operation processor 2, and other device than the device concerned of plural operation processors 11, 12 which have been connected to the main storage device 3 is allowed to continue a processing of a reference and updating. |
