Scheduling Batch Jobs Using a BenchMark Procedure
If you want to initiate batch jobs from within the USoft product set, you can use a recursive BenchMark procedure calling the job at regular intervals.
This can be used for jobs that run at regular intervals, but also for jobs that depend on clock time. In the latter case, use date fields, the CURRENT_DATE() function, or join with the T_APP_TIME table.
Batch scheduling is made independent of the environment USoft is deployed in. It has maximum maintainability because batch scheduling is registered in the application database.
A disadvantage is that a BenchMark session must run continuously.
The following example discusses an application where jobs are scheduled to execute at a certain date and time registered in a date field.
To schedule batch jobs using a BenchMark procedure:
WHERE fired_at < CURRENT_DATE()
Step 1 Action = action-decision(EXECUTE_JOB)
Step 2 Procedure = P1
This means the procedure calls the decision, then calls itself, so that the decision call is repeated endlessly until the BenchMark test playing the procedure is stopped manually. (You will set an interval between decision calls in step 5.)
You have flexibility flexible in designing one-time or recurrent scheduled jobs, or any other type of construction, because the scheduling information is part of the application itself. By creating a child table for the SCHEDULED_JOBS table, you can manage any number of job parameters.
