Abstract

PURPOSE:To make it possible to obtain the processing result in execution without terminating the job and to resume the job from an interruption point. CONSTITUTION:A job discriminating means 2 discriminates a request to be an object based on the request received by a job temporary interruption request reception means 1. A job temporary stoppage means 3 temporarily stops the discriminated job. A job execution space storage means 4 stores the execution space of the job in a file. A job execution result output means 5 stores the execution result of the job up to the time in a file 33 for print output 33 and performs a print output request for the control program of a system. A job execution resumption means 6 resumes the execution of the job stopped by the job temporary stoppage means 3 after the storage of the job execution space and the output of the job execution result are terminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a job suspension method, and particularly to a method for acquiring a result during the execution of a job in a system using a job that requires a long time to execute such as scientific and technological calculations, and a job at the time of a failure. The present invention relates to a job suspension method that saves a job execution status in order to resume execution from the middle.

[0002]

2. Description of the Related Art In the prior art, since the execution result was not obtained until the job was completed, in order to obtain the result during the execution of the job, a job suspension request is made and the execution state of the job is saved. Had to be finished once.

[0003]

According to the conventional technique described above, since the job is once ended, in order to continue the process, the file in which the execution state of the job is saved is input and the job is re-entered. It has the drawback of having to.

[0004]

According to the job suspension method of the present invention, the processing of a job being executed in the system is temporarily stopped, the execution result up to that point is output, and the execution state of the job is saved ( (Hereinafter referred to as job suspension) When a request is made from the system console, a job suspension request acceptance unit that recognizes the request as a job suspension request, and a request that is accepted by the suspension request reception unit Job identification means for identifying a job, job suspension means for temporarily suspending the job identified by the job identification means, job execution space storage means for storing the execution space of the job in a file, and the like. A job execution result output function that stores job execution results in a file for print output and requests print output to the system management program. When configured to include a resume job execution resuming means the execution of the job that is stopped by the job temporary stop means after storing and job execution result output of the job execution space it has been completed.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The job suspension method shown in FIG. 1 includes a job suspension request reception unit 1, a job identification unit 2, a job suspension unit 3, a job execution space storage unit 4, a job execution result output unit 5, a job execution restart unit 6, and a job execution unit. Space 11,
It comprises a system console 21, a printer 22, a job execution space storage file 31, a job execution result file 32, a print output file 33, and a print output program 41.

Next, the operation will be described. In a system that uses jobs that take a long time to execute, such as scientific and technological calculations, a request to obtain the execution result during the execution of the job, and to save the execution status of the job to restart the job during the failure The request is defined as a job suspension request, and these requests are made from the system console 21 at an arbitrary time.

A job suspension request received from the system console 21 is received by the job suspension request reception means 1. The job accepted by the job suspension request accepting means 1 is searched and identified by the job identifying means 2 from the jobs being executed in the system for the job to be requested.

The following processing is performed on the job identified by the job identifying means 2 in this way. The job suspension means 3 suspends the execution by removing the job from the CPU allocation target. The job execution space storage unit 4 stores the virtual storage space of the job stopped by the job suspension unit 3, that is, the job execution space 11 in the job execution space storage file 31.

Further, in order to output the execution result of the job up to that time, the job execution result output means 5 stores the job execution result file 32 in the print output file 33 and issues a print output request to the print output program 41. To do. The print output program 41 is a program of an operating system that outputs the print output file 33 to the printer 22 in response to a print output request.

When all the temporary suspension requests for the target job have been completed by the above means, the job execution resuming means 6 restarts the job execution by returning the job to the target by the CPU allocation.

[0012]

As described above, according to the present invention, the processing result of the job being executed can be obtained without terminating the job, and the interruption point is described in the program executed by the job in advance. Since you can set a break point for the job from the console etc. at any time, when the execution of the job is aborted for some reason,
There is an effect that the function of resuming a job from the interruption point becomes possible regardless of the characteristics of the program.

Claims (1)

[Claims] 1. A request from the system operator console for temporarily stopping the processing of a job being executed in the system, outputting the execution result up to that point, and saving the execution status of the job (hereinafter called job suspension) Job suspension request receiving means for recognizing the request as a job suspension request when made, job identifying means for identifying a target job from the request received by the suspension request receiving means, and job identifying means A job suspension means for temporarily suspending the job identified by the job execution space, a job execution space storage means for storing the job execution space in a file, etc., and a system for storing the execution results of the jobs up to that point in a file for print output. Job execution result output means for issuing a print output request to the management program of the And a job execution resuming means for resuming the execution of the job stopped by the job suspension means after the end of the output of the result.
