PURPOSE:To prevent an information processor from degrading its performance by executing the abnormal end of an instruction for allowing a service processor to substitute processing in each execution of the instruction after once detecting abnormality. CONSTITUTION:A means 12 requests the service processor 10 to substitute processing by a prescribed instruction, and when the processing is not ended within fixed time, a means 14 judges the generation of abnormality in the service processor and the judged result of service processor abnormality is stored in a means 16. When the judged result of service processor abnormality is previously stored in the mean 16, the instruction is forcedly ended as abnormality by a means 18. Thus, the processing stop time due to the abnormality of the service processor 10 can be remarkably shortened. |
