Abstract
An error recovery reduces the recovery time in finding out the JOB causing error in a computer system. An event generation unit is called at the beginning of the execution of a JOB, at the end of the execution of the JOB and at the close process of the file input-output process, by the JOB execution control unit. The JOB start event, end event, and close event are generated by the event generation unit. A file input/output count acquisition unit is called to generate a file input/output count for each JOB, by the JOB execution control unit. The monitoring process thereby generates the execution record comprising the end code, the start time, the end time, the execution time, the file input/output count, and the error flag for each JOB, based upon the above mentioned events. The monitoring process activates the error recovery support process when the error occurs. The error recovery support process compares the execution record with the standard record based upon the normal execution, checks for an abnormality of the input/output count, the execution time and the end code, stores the abnormal flag into the execution record, and sets the JOB generating the abnormality as the JOB caus…
