3.5.2 Setting multiple execution start times

Sometimes, you may need to operate a jobnet according to a complex schedule that cannot be expressed by a single schedule rule. JP1/AJS3 allows you to create multiple schedule rules for a jobnet. You can define up to 144 schedule rules for a single jobnet. When multiple schedule rules are defined, the schedule is set with the earliest schedule rule.

For example, you may want to run a jobnet multiple times a day at fixed times, or for the jobnet to have different execution times on different days of the week. In such cases, you can define the schedule for the jobnet by creating multiple schedule rules. If more than one execution is scheduled for the same execution start date and time, as a result of setting multiple schedule rules, then the jobnet is executed only once.

Note that when you set multiple schedule rules, a jobnet may end up being scheduled for execution more than once at the same execution start time. In this case, the jobnet will be executed only once.

The following is an example of a schedule with multiple schedule rules.

Figure 3‒4: Schedule with multiple schedule rules

This schedule is for a jobnet that will execute twice a week, at 9:00 on Monday and 17:00 on Friday.

Schedule rule #1 defines Monday's schedule, and Schedule rule #2 defines Friday's schedule. When you register the jobnet for execution, the execution schedule for the jobnet is calculated based on both of these schedule rules.
