PURPOSE:To continue processing even if the trouble that the power source of a processor is turned off occurs, by providing a data processing system with an execution display means, an execution process display means, a shared resource update display means, a power break abnormality detecting means, and a control means. CONSTITUTION:If the abbormality of power break occurs in a data processor 30, this state is reported to a diagnostic controller 4. The execution display means of the processor 30 is tested, and contents of a corresponding execution process display means are read out if the execution state is detected. If the readout process is a critical process, the control is set to the abnormal stop state. If it is not a critical process, all lock byte contents are checked; and if there is one or more locks which the processor 30 acquires, the processor 30 is judged to be updating shared resources, and the system is set to the abnormal stop state. If there are no locks, the process is set to the abnormal interrupted state and the data processing is executed continuously by other data processors 31-33 if the resource update display means does not indicate updating. |
