PURPOSE:To reduce the necessary time for a stored program type computer system, by transferring only the information different from the initial information among the memory information in a main storage device to an external auxiliary storage device. CONSTITUTION:A software fault detector ALM receives the signal with every certain period of time and confirms the normal state of a system. If an error arises in the software, no signal is received at the detector ALM although a certain period of time elapses. Thus the ALM detects the fault of the system and applies an interruption to a processor CC. Receiving the interruption, the processor CC transfers the fault information collecting program P3 in an external auxiliary storage device EMEM2 to a main storage device MEM and gives a start. The program P3 performs a comparison between the memory information in the storage region where no inhibition is given to the writing within the device MEM and the data P2 of the system program in an external auxiliary storage device EMEM1. And only the dissident memory information of the MEM is transferred to a file P4 in the EMEM2 to reduce the necessary time. |
