Abstract

PURPOSE:collect the fault information for a single information process system, by transferring the contents of a main storage to an external auxiliary storage device immediately before the function of the information process system is discontinued by a software fault and the system is actuated for initial start again. CONSTITUTION:A single information process system is formed with a processor CPU1, a main storage device MEM2, an external auxiliary storage device EMEM3 and a fault detector ALM4. In case a fault such as a bug of software, etc. arises, a fault is in the system is decided as long as the detector ALM4 is impossible to receive the timing signal from the CPU1 even in lapse of a certain period of time. Thus an interruption is applied to the CPU1 from the detector ALM4, and the CPU1 analyzes the factor of this interruption. Then the CPU1 loads the fault information collection program in the device EMEM3 to a part of the device MEM2, transfers the contents of the MEM2 to a magnetic tape controller MTC5 of the EMEM3 and records the fault information to a magnetic tape unit MTU6.
