Problem

Sometimes instances of a periodic order execution has orders have to be skipped, e.g. for maintenance. This recipe describes how you can to skip one ore or more planned executions of an order using schedules.

...

Configuration

Assume you have an order which should be start started at 10 p.m. every day. Normally you would place add a runtime run-time like this directly in to the order configuration:

 <period  single_start="22:00"/>

Using a schedule the runtime run-time is placed located in a single configuration element:

 <schedule name="every_day_at_10pm">
    <period  single_start="22:00"/>
 </schedule>

The order referenced to will reference this schedule as follows:

 <order ...>
    ...
    <run_time schedule="every_day_at_10pm"/>
 </order> 

Now it is possibile to substitute the schedule 'every_day_at_10pm' by another one schedule for a specific time range. For our purpose we need a schedule that produces a manual start of the orderno run-time:

 <schedule substitute="every_day_at_10pm" valid_from="2013-01-01 00:00:00" valid_to="2013-01-01 01:00:00" name="manual_start"/>

...

In this example the schedule substitute manual_start is effective for the first hour of the year 2013.

Solution

After preparing the configuration described above you can skip the daily runtime run-time for a specific time range using JOC as follows:

• Choose the 'Schedules' tab in JOC
• Select the schedule 'manual_start'
• Choose 'Edit schedule' in the 'Substitute menu'
• By clicking 'runtime editor' you can change the time range the substitute is active.overlays the default scheduler every_day_at_10pm.
