Abstract

PURPOSE:To make the operation of a system efficient by activating a job based on data concerning designated job activation when a job generating request is sent from a program during an execution, stopping the execution of the program, generating the other job from the program during the execution, and synchronizing the job. CONSTITUTION:A program 11 notifies an information group concerning the job activation to a job generation control means 12, and the job generation control means 12 notifies the activated information to a job activating means 13. The job activating means 13 requires the stop of the program 11 from a program stopping/restarting means 16, and then activates a job 14. At such a time, the job name and job serial numbers of the program are stored in a job control table 17. When the job is completed, a job completing means 15 references the information to the program which has generated the job stored into the job control table 17, requires the restart of the program from the program stopping/restarting means 16, and restarts the execution of the program.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a job generation method, and more particularly to a job generation method from a program being executed in an electronic computer.

(Prior Art) Conventionally, in a job generation method in which a separate job is generated from a program being executed in a computer, the jobs on the generation side and the job on the generated side operate asynchronously.

(Problem to be Solved by the Invention) In the conventional job generation method described above, when a different job is generated from a program that is currently being executed, execution of the program that requested generation is temporarily stopped, and the generated job is terminated. When this happened, it was not possible to resume the execution of the program that had requested the start, that is, it was not possible to synchronize between the two.

Therefore, if you want to generate another job from a running program and continue processing the program that requested generation based on the processing results of the generated job, you must terminate the program once after requesting job generation. However, when the generated job is finished, the program has to be started again.

(Means for Solving the Problems) A job generation method according to the present invention includes a first means for receiving data regarding the job activation specified by the program when a job generation request is sent from the program being executed. , a second means for starting a job and stopping execution of the program based on the data received by the first means, and a third means for terminating the job and restarting execution of the program. By preparing the program, another job can be generated from the running program and synchronized.

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

FIG. 1 is a block diagram showing an embodiment of the job generation method according to the present invention.

In FIG. 1, this embodiment includes a job generation control means 12, a job start means 13, a job end means 15, a program stop/restart means 16, and a job management table 17.
It is composed of:

FIG. 2 is an explanatory diagram showing the flow of a job when a job is generated according to the job generation method of this embodiment.

In FIG. 2, execution of the program that requested job generation is temporarily stopped, and execution is resumed when the job started by the job generation request is completed.

FIG. 3 is an explanatory diagram showing information stored in the job management table 17, in which the job name 31 of the program that generated the job, the job serial number 32, and other information regarding the job are stored together with various information indicating the job. has been done.

Hereinafter, a process of generating a job from a program being executed and waiting for the end of the job according to the embodiment shown in FIG. 1 will be described.

The program 11, which includes commands for requesting job generation and waiting, executes the above commands and notifies the job generation control means 12 of a group of information regarding job activation.

The job generation control means 12 notifies the job starting means 13 of the starting information notified from the program 11.

In the job starting means 13, the program stopping/resuming means 1
6 to program 11. job 14 after requesting that it be stopped.
Start. Also, at this time, the job management table 17
The job name and job serial number of the program are stored in the information storage fields 31 and 32 of the program that generated the job.

When the job is not completed, the job termination means 15 refers to the information of the program that generated the job stored in the job management table 17, and requests the program stop/restart means 16 to resume execution of the program.

The program stop/restart means 16 restarts the execution of the program.

(Effects of the Invention) As explained above, the present invention allows you to generate another job from a program that is being executed and to continue processing in the program based on the processing result of the job, for example, when the program is terminated once -. It is possible to make the program wait until the job ends without performing troublesome control such as restarting the program when the job ends. As a result, the present invention has the effect of streamlining the operation of the system. This is particularly effective for programs that are often left running for long periods of time, such as online office programs.
