Clustering Scheduled Services

[sana13]

I want to write a scheduled service in JBoss AS. The instances of the JBoss AS are clustered. This scheduled service should be running on a daily basis for a particular no of times. Can this service be clustered in such a way that if it fails at one node in its fourth count , it can be picked up by the other node and continue from the next  count onwards?

Yes, you need to use the Scheduler service and turn it into a cluster singleton. That's simply done by deploying your service into a special directory (under /deploy/singleton), I forgot the exact name.

If you google for singleton service, scheduler, or cluster singleton you should be able to find the right documentation.

Cheers,

The deployment directory for clustered singletons is: $JBOSS_HOME/server/<your-profile>/deploy-hasingleton/
