Abstract

PURPOSE: To perform an adequate treatment according to the degree of necessity for backup and without giving any hindrance to the process, by securing a mutual storage of the program which works when an emergent backup is required in each of several computers.
CONSTITUTION: Arithmetic control unit 13A gives a control to the process 12A at the normal time by the control program A. And in case when the unit 13A has some breakdown under the control of the particularly important item of the process 12A and when no short break is allowed, the emergency information JA is given to the main memory 18B within the arithmetic processor 13B to start the emergent control program KA within the bulk 16B. In case when the unit 13A becomes faulty under the normal control, the processor 13B carries out the control program B and at the same time performs the initialization of the process A system. After this, the program A is started. In this way, both the quick comformity and the reliability are enhanced for the backup.
