PROBLEM TO BE SOLVED: To provide a management system which quickly restart plural resident processes regardless of abnormal termination by efficiently managing them without applying a heavy load to a CPU with a simple constitution. ;SOLUTION: A master process 1a successively starts plural resident slave processes P1 to Pn by a process start means 11, and a process ID management means 12 registers process IDs in a process ID management table 21. Each of slave processors P1 to Pn starts operation after locking a common semaphor by a process start report means, and the semaphor value of the semaphor 3 becomes 0 when all slave processes are operated. Finally, the master process 1a starts a process monitor means 13 and sets the semaphor 3 to the lock waiting state to monitor the processes. If a slave process is abnormally terminated, the semaphor 3 is unlocked, and the process monitor means 13 immediately recognizes it, and a faulty process extraction means 14 refers to the process ID management table 21 to detect this slave process and restarts it.;COPYRIGHT: (C)1997,JPO
