ABSTRACT:
A technique for preventing downtime in a redundant computer system having several processors without disconnecting any of the processors from the system. When an abnormality of a processor is detected, a pulse signal which assumes a HIGH value at a predetermined period is supplied to a busy controller of the processor to set the processor in a waiting state. In response to the HIGH value of this signal, the busy controller outputs a busy signal to set the processor in a waiting state and shifts an execution timing of data processing of the processor from that of a normal state, thereby preventing recurrence of the abnormality.
