Starting Situation

  • We have a job chain which is set to run every 15 minutes. At random point thought the day this order gets stuck in a running state.

How to disable microscheduling for releases before 1.7.3

You can disable the microscheduling in your JobScheduler environment manually by setting the following parameter in ./config/scheduler.xml:

Configuration for scheduler.xml
    	<param name="scheduler.old_microscheduling.enable_for_jobs" value="false"/>


A restart of JobScheduler is required to apply this setting.
