Abstract

PURPOSE:To execute the reprocessing of job by minimum work by providing a storing means to store the latest processing name and a control means to activate a processing means based on the stored latest processing mane and restarting the execution from an interrupted processing part. CONSTITUTION:When a job program P1 of a program part 121 is completely executed, an execution register part 131 registers a program name 'PROG1' of the job program P1 to the job state control file of a storing means 20. Next, when a job program P2 is executed and completed, a job program P3 is executed. At such a time, when the execution of the job program P3 is interrupted, a program name 'PROG2' is registered to the storing means 20. In the case of the reprocessing, the program name 'PROG2' is obtained from the storing means 20 according to the reprocessing control program of a control part 32 and the execution is started from the job program P3 while skipping the reading of processings for executing and registering the job programs P1 and P2. Thus, the time required for the reprocessing is shortened.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a business reprocessing method for reprocessing businesses in a batch processing system.

[Conventional technology]

In the execution process of business processing on a computer,
Execution may be interrupted midway due to various reasons.
There may be a need to execute the same task again.

In business processes where multiple programs are executed sequentially, the conventional method is to re-execute the first program.

[Problem to be solved by the invention]

As mentioned above, when executing an interrupted business process from the first program, take some measure (such as saving and restoring all mask files) to return the contents of the mask file updated up to the interrupted program. It is necessary and requires a lot of work.

An object of the present invention is to provide a business reprocessing method that can eliminate such drawbacks and improve ease and flexibility.

[Means to solve the problem]

The present invention is a business reprocessing method that sequentially executes the processing parts when executing a business process consisting of a plurality of processing parts. processing means for sending out the processing name of the processed part; storage means for receiving the processing name sent from the processing means and storing the latest processing name; and a control means for starting the processing means, and when execution of a processing part by the processing means is interrupted, the processing means resumes execution of the starting part from the processing part where execution was interrupted under the control of the control means. It is characterized by

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a functional diagram showing one embodiment of the present invention. 1st
The business reprocessing method shown in the figure includes a processing means 10, a storage means 20, and a control means 30.

The processing means 10 includes an execution restart control section 11, a program section 12. -12N, and executed registration units 131 to 13s.

The control means 30 includes an input section 31 and control sections 32 and 33.

The storage means 20 of such a business reprocessing method includes a job status management file. As shown in FIG. 3, the content of the job status management file is a table file in which job names and program names are registered, and the program name of the executed program can be registered for each job. For a certain job, the most recently registered executed program name is stored.

The input section 3I of the control means 30 is for inputting a job name.

The control unit 32 performs processing using a reprocessing control program. The reprocessing control program is activated by an operator when a job needs to be reprocessed. This program includes the job name given to the input section 31 by the operator at the time of startup, the job status management file in the storage means 20,
According to the reprocessing control table of the control unit 33, the processing means 1
It has the function of setting the sense switch corresponding to the reprocessing start program of the executed program 0 and then starting the job with the given job name. The sense switch is a logical switch that is valid between programs and is O3 (Op
This is due to the function of the aging system.

The control unit 33 includes a reprocessing control table.

As shown in FIG. 4, the reprocessing control table is a table that stores sense switch values corresponding to job names and program names, and is set in advance for each job.

The processing means 10 is executed and controlled by a job control language (JCL) or the like.

The execution start control unit 11 of the processing means 10 has a function of determining the value of the sense switch by using the execution control function of the JCL and starting execution of a business program corresponding to the value. Specifically, as shown in FIG. 5, this method uses the JCL execution control function to skip a specific JCL without executing it.

During normal execution, if the sense switch is not set, execution starts from the first program.

Program section 12 of processing means 10. ．． 12□, 123

Executed registration section 13. ．． 13□, . . . , 13M perform processing using a program having a function of registering the executed program name in the job status management file of the storage means 30. This function records which program has completed execution.

Next, the operation of this business reprocessing method will be explained with reference to the execution flowchart shown in FIG.

When an operator instructs to execute JOBA consisting of business programs P1 to Pn, job A is executed in the order of JCL. The execution start control function of the execution start control unit 11 does not function because the sense switch is not set at this time (step Sl). The business program P1 of the program section 12□ is executed (step S2). When the execution of the business program P1 is completed, the executed registration unit 13
I is the program name rPROG of the business program PI
1'' is registered in the job status management file of the storage means 20 (step S3).

Next, the business program P2 of the program section 12z is executed (step S4). When the execution of the business program P2 is completed, the executed registration unit I3□ registers the business program P2.
2's program name "rPROG2" is registered in the job status management file of the storage means 20 (step 35).

Subsequently, the business program P3 of the program section 123 is executed (step S6). At this time, if the execution of the business program P3 is interrupted, the item "rJOBA" in the job status management file of the storage means 20 will contain rPR.
OG2. is registered.

In step S6, after removing the cause of the interruption of the business program P3, rJOBAJ of the business program P3 is
When reprocessing, the operator instructs the control unit 32 to execute the reprocessing control program (step S7).

At this time, the operator selects the job name rJOB to be reprocessed.
AJ is specified from the input section 31. The reprocessing control program of the control unit 32 selects the file ``rPROG2'' from the item ``rJOBAJ'' in the job status management file of the storage unit 20.

You can get the program name. Also, the reprocessing control table of the control unit 33 is drawn, and rSW2. The value of is obtained. Furthermore, after the sense switch corresponding to rSW2J is set, the JCL of rJOBA is specified, and rJOBA
J is activated. rJ.

In the JCL of BA, the sense switch is determined by the execution start control unit 11 (step S8).

Then, the process of executing the business programs PI and P2 and registering them is skipped, and the execution is started from the start program (business program P3) corresponding to the value (step S9), and the job processing is continued. I do.

In this way, this embodiment uses JCL (job control language), an execution start control function, an executed registration function, a job execution management file, and a reprocessing control program to control the execution of the Ba Nochi processing system. Reprocess the process. According to this, in order to perform reprocessing after an interruption, it is only necessary to remove the cause of the interruption, and processing can be restarted from the interrupted program.

In this embodiment, when it becomes necessary to reprocess a job, the following effects can be obtained by executing the program from the program that has been completed.

(1) It is possible to use a method that does not require recovery work for files, etc. to execute business processing from the beginning.

(2) Since it is not necessary to re-execute a completed program, the time required for re-processing can be shortened.

(3) The work required for reprocessing can be made unnecessary by incorporating the setting of an execution start point, saving and restoring transaction data and intermediate files into JCL during reprocessing.

(4) It can be used as a simple fault countermeasure in computer systems that do not have functions such as journals required for fault recovery.

〔Effect of the invention〕

As described above, the present invention has the effect of allowing business reprocessing to be carried out with a minimum amount of work.
