When all the examination conditions are satisfied, business transaction data 4-28 is generated and registered in input queue 4-3. Further, the processing result record 4-29 for registering the processing result and the like when the business program executes is generated in the processing result DB. The business transaction registered in the input queue is scheduled and executed by the scheduling function of the DB / DC system.

FIG. 5 shows the data format of a business transaction registered in the input queue. The transaction data is composed of a common part 5-1 and a work specific part 5-2. The common part is a terminal common table part 5-11 containing information on terminals and operators and a restart flag part 5 showing the status of interruption and restart. -
12 and a key portion 5-13 having a key of the processing result DB and a program information portion 5-14 having program information constituting a job. The business specific section is an area that is individually set by each business processing program.

FIG. 6 shows an outline of business processing. The business transaction 6-1 registered in the input queue in the qualification examination / collective activation acceptance examination is scheduled by the scheduling function 6-2 of the DB / DC system, and when the space becomes available, the first business processing program 6 Control is passed to -3. In the top job processing program, the job start status information 6 is stored in the execution status areas 6-41 and 6-51 of the execution management DB 6-4 and the processing result DB 6-5, respectively.
Register -31 and 6-32 and start processing. When the program ends, the end status information 6-33 is registered in the processing result DB, the transaction data 6-34 of the business processing program to be started next is generated, and registered in the input queue to end the program. In this way, the programs constituting the business process are executed one after another. In the final program for business processing, the completion status information 6-35 is registered in the business execution management DB and all processing is completed.

FIG. 7 shows the transition of the execution status of the execution management DB. In Figure 7, there is ongoing work 7-
2 indicates that the work to be processed continues after the own work, and none 7-1 is the work that is completed when the own work is completed. At the time of start, the execution status is in the unexecuted status 7-10. When the qualification examination / collective activation acceptance examination accepts the activation request from the terminal, the execution waits 7-11.
When the job starts, it becomes 7-12, and when it finishes, it becomes 7-13. When multiple processes are being performed, waiting for execution again 7-14 in the waiting state and continuation of the running status 7-15 at the end of execution occurs. In addition, when there is a continuous operation, the status of execution completed is 7-21 when the operation is completed, and the status of unexecuted is 7-22 when the next operation is completed. FIG. 8 shows details of the processing timing and the status for each processing category.
In FIG. 8, the presence of a plurality of statuses indicates a case of multiple processing. Error 8-1 in the figure shows the case where there is a start request before the completion of the next work.

FIG. 9 shows the transition of the processing status of the processing result DB. The pending status 9-1 set in the initial state in the qualification examination / batch activation acceptance examination is updated to the running status 9-2 at the start of the work and the execution completion status 9-3 with the end of the work. If the suspension time is reached during business processing, the suspension status is 9-4, and if the termination is abnormal, the termination status is 9-5. FIG. 10 shows details of processing timing and set contents for each processing category. In the figure, the status set at abnormal termination 10-1 is the post-abnormal termination processing, the reset of the running status at abnormal termination restart 10-2 is the abnormal termination restart processing, and the interrupted restart processing is at 10-3. Is reset by the interrupted work restart process.

FIG. 11 shows an outline of the interruption process. The business processing program periodically refers to the processing interruption flag 11-10 of the end management table 11-1 to check the status of necessity of interruption. When the interruption time is reached, the interruption time control processing 11-2 is activated by the timer transaction registered by the online start processing program, and the interruption flag 11-11 is set in the processing interruption flag portion 11-10 of the end management table. When the processing interruption flag is detected 11-3 by the business processing program, the contents processed up to that point are set as the takeover information in the business-specific part of the transaction data and registered in the interruption DB 11-4. Further, the status of interruption end is set in the processing result 11-51 of the processing result DB 11-5, and the processing is ended. The suspended business processing program is read out in the suspended business restart processing 11-6 of the online start processing on the next day, re-registered in the input queue, and then executed.

FIG. 12 shows an outline of processing when an abnormality occurs. An abnormal condition is detected and abnormally terminated by the business processing program 12-1 and the DB is automatically recovered by the DB / DC system 12
-2 is executed and the post-abnormal end processing program 12-3 is started.
The abnormal termination post-processing program analyzes the cause of the abnormal termination, determines the blocking range according to the degree of its impact, and registers it in the command blocking table 12-31. Furthermore, update the execution management DB and the processing result DB in the process status,
After storing the abnormal end information 12-32 in the abnormal end DB, the administrator terminal is notified 12-4. The administrator inquires 12-5 of the abnormal termination information from the terminal, grasps the failure status, and seeks the cause of the abnormal termination. If the cause of the abnormal termination is found and the cause of the failure is removed, the administrator releases the command block.
12-6 and restart the job that ended abnormally 12-7.

FIG. 13 shows an outline of the collective DB deletion process for automatically deleting unnecessary data spaces. In this method, the method of allocating / deleting the data space to be used for each job has a problem in operation and performance. Therefore, the fixed allocation method is adopted, and unnecessary data is deleted at any time. The process for deleting all unnecessary data spaces is performed by the online start process.
The timer is started from -1, and the deletion target data is selected and deleted based on the calendar information 13-21 and the storage period information 13-22 on the storage time limit DB 13-2. The calendar information has a target file group according to the day of the week, and the storage period information has a data storage period for each file, and the data that has passed the storage period is the deletion target 13-3. If the suspension time is reached during the batch deletion process, the suspension information is registered in the suspension management information 13-23 and taken over the next day. In this way, data is maintained and disk space is effectively used.

[0023]

As described above, according to the present invention, by incorporating the batch processing control function in the online system,
The user can freely start the batch job without the intervention of the center operator, can confirm the execution result early and can obtain the result list, which is effective for rationalization. In addition, the load on the center operator can be greatly reduced by the batch job automatic suspend / resume processing function, etc., and the early detection and localization of the failure can be performed by the detailed error information acquisition function when a failure occurs and the work blocking function according to the level. This is also effective from the standpoint of improving maintainability.
