Abstract

PURPOSE: To reduce the service interrupting time, by constituting the data processor as completely duplicated one, and providing the timing circuit and counter circuit for the emergency circuit which automatically reconstitutes the normal system at failure.
CONSTITUTION: Main memory devices 10, 11, central controllers 20, 21, channel devices 30, 31 external file memory controls 40, 41, and external file memories 50, 51, respectively constitute the data processor of duplicate system of 0 and 1 systems. At the failure of the system, the emergency circuit 60 which reconstitutes the normal system, has the timing circuit which initially sets the data processor and the counter circuit indicating the number of starts of the circuit 60. When the count value of the counter circuit is within the specified value, program is operated from the fixed address of the main memory, and when the count value of the counter is a given value or more, the program is loaded with the designated memories 50 and 51. Thus, the restart processing program is simplified and the service restart time of the system in which the initial set program is not required to be loaded at all times, can be reduced.
