This option is used to inspect the runtimes of the orders of a job net (the so-called FrequenyChecker will be executed).
That means:
-
All orders of a job net with the parameter on_demand='true' will be marked in the database (the field IS_RUNNER_ON_DEMAND
of the table SCHEDULER_JOB_NET_PLAN will be set to true). JobScheduler stops the execution of the job net before this this
order and waits till the order started manually.
-
The runtime defintions of the job net orders will be analyzed. It is decided if an order for the just created job net plan should be executed.
This is the case if the order has a runtime within the given time horizon (see parameter TimeHorizon).
Sample:
Order A starts every Monday at 10 a.m.:
<run_time let_run="no">
<weekdays>
<day day="1">
<period single_start="10:00"/>
</day>
</weekdays>
</run_time>
