Abstract
In a processing system having a plurality of CPUs, a common storage device is shared by all the CPUs, online control programs are executed by the CPUs, and monitor programs monitor the states of the online control programs and control the online control programs. When a failure of an online control program occurs, the process of the failed online control program can be taken over by another online control program. A method of recovering from the failure of an online control program is characterized by quick restart information for each online control program which is stored separately in the common storage device and separate from a log.
