PURPOSE:To eliminate operator's labor and to perform accurate, centralized job operation control by scheduling an automatic job flow according to the format of operation to be objective of a data processing system. CONSTITUTION:Read processing 9 of a job class schedule table 4 is executed, and a date, start and an end time, job class, etc., are set in a memory for an execution job class table 21. The current date and time are obtained from a timer mechanism 5 to retrieve date and time information in the table 21, and a time comparison 10 is made repeatedly until the coincidence with the date and time of the timer mechanism 5 is obtained. Once the coincidence is obtained, a decision on whether there is a job being executed at present, and when no job is found, the deletion processing 12 of the current job class and the start processing 13 of a new job class are performed. Then, job execution decision processing 16 is performed to read the processing of each job class, etc., from a definition table 7, and a job 8 queuing for execution is read in. When the time obtained by subtracting the processing time of the definition table 7 from the ending time of the table 21 is smaller than the time of the timer mechanism 5, the start processing 17 of the job is executed. |
