Abstract

PURPOSE:To decrease the incidental work of an operator by selecting the job of the largest job description capacity of an execution completion and automatically deleting it from the memory area of an auxiliary memory when the idle area on the auxiliary memory is the specified threshold or below. CONSTITUTION:In the main memory of a data processor 1, a system scheduler 2, which is a control program to execute the execution control of the job, is stored. The scheduler 2 activates a monitoring part 5 at a prescribed period and acquires the idle area of an auxiliary memory 3. Next, a deciding part 6 decides whether or not the idle area is the specified threshold or below, and at the time of being the threshold or below, a selecting part 7 selects the job with the largest job description capacity to complete the job execution from the top of the auxiliary memory 3. A deleting part 8 deletes the selected execution completion job from the tip of the auxiliary memory and completes the processing. When the idle area is larger than the specified threshold, immediately, the processing is completed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention retains job description information in a storage area on an auxiliary storage device before executing a job, thereby making it possible to re-execute the job even after the job has been executed. Conventionally, this type of input job management method has been used to store input jobs in an auxiliary storage device every time the execution of a job is completed. The job is selected and deleted.

[Problem to be solved by the invention]

The conventional input job management method described above selects and deletes the job with the longest residence time in the auxiliary storage device every time one job finishes executing. As a result, the capacity of the auxiliary storage device becomes enormous, which requires the operator to delete jobs from the system at an appropriate time, resulting in an increase in the operator's incidental work. Furthermore, if there is a shortage of storage space on the auxiliary storage device required for job execution due to a delay in operator operation, there is a drawback that execution of the job cannot be started and the job being executed may end abnormally.

[Means to solve the problem]

The input job management method of the present invention is a computer system that maintains job description information in a storage area on an auxiliary storage device before executing the job, thereby making it possible to re-execute the job even after the job has been executed. a monitoring unit that monitors the free space of the storage area on the auxiliary storage device at a predetermined cycle;
a determining unit that determines whether the free space of the storage area on the auxiliary storage device is equal to or less than a predefined threshold based on the result of the monitoring unit; is less than the threshold, a selection unit selects a completed job with the largest job description capacity based on the job description information held on the auxiliary storage device, and and a deletion unit that deletes the completed execution job from the storage area on the auxiliary storage device.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. Job description information is stored on the auxiliary storage device 3 prior to job execution. A system scheduler 2, which is a control program that manages job execution, is stored in the main memory of the data processing device 1. The system scheduler 2 includes a recording unit 4 that stores job description information on the auxiliary storage device 3 before starting job execution, a monitoring unit 5 that monitors the free space on the auxiliary storage device 3 at a predetermined cycle, and Part 5
A determining unit 6 determines whether the free space on the auxiliary storage device 3 is below a predefined threshold based on the result of
A selection section 7 refers to the above job description information and selects the job with the largest job description capacity for which job execution has been completed, and the job description information selected by the selection section 7 is stored in an auxiliary storage bag N3. A deletion unit 8 for deletion from the area is provided.

FIG. 2 is a flowchart showing supervisory control in this embodiment. The system scheduler 2 activates the monitoring unit 5 at a predetermined period. The monitoring units acquire the free space of the auxiliary storage device 3 (process A), and then the determination unit 6 determines whether the free space is below a specified threshold (process B). If it is below the threshold, the selection unit 7 selects the job with the largest job description capacity for which job execution has been completed from the auxiliary storage device 3 (C), and the deletion unit 8 selects the completed job from the auxiliary storage device. 3. Delete from above (D) and end the process. If the free space in process B is larger than the specified threshold value, the process ends immediately.

〔Effect of the invention〕

As explained above, the present invention monitors the free space on the auxiliary storage device at a predetermined period, and if the free space is below a specified threshold, the job execution is completed for the job with the largest job description capacity. By selecting a job and automatically deleting that job from the storage area on the auxiliary storage device, the operator's incidental work is reduced, and there are no bottlenecks in starting execution or abnormal termination of the job being executed. .
