How-To: Shutting Down a Scheduler

To shutdown / destroy a scheduler, simply call one of the shutdown(..) methods.

Once you have shutdown a scheduler, it cannot be restarted (as threads and other resources are permanently destroyed). Also see the suspend method if you wish to simply pause the scheduler for a while.

Wait for Executing Jobs to Finish

//shutdown() does not return until executing Jobs complete execution
scheduler.shutdown(true);

Do Not Wait for Executing Jobs to Finish

//shutdown() returns immediately, but executing Jobs continue running to completion
scheduler.shutdown();
//or
scheduler.shutdown(false);

If you are using the org.quartz.ee.servlet.QuartzInitializerListener to fire up a scheduler in your servlet container, its contextDestroyed() method will shutdown the scheduler when your application is undeployed or the application server shuts down (unless its shutdown-on-unload property has been explicitly set to false).
