    JBossMQ failover issues

    Ali Gohar Newbie

      Hi,

      I am running two jboss instances in a cluster and deployed different queues/topics in all/deploy directory, but when i kill or shutdown first node, the other node is not able to take over and deploy the queues on it. I get following errors:

      Looks like the problem is only for DLQ queues, get the same above error for my own application defined DLQ queues.

      I am running JBoss-4.2.2.

      I've tried to deploy the queues to deploy-hasingleton directory but the problem is same. These queues are backed up by db.

      Does anyone has any clue?

      Thanks

      PS: i've also tried to put them under deploy-hasingleton/jms directory but of no use

          The issue is fixed, but not sure what is the real cause.

          I was using Queues backed up by MySQL datasource defined in default-ds.xml and i configured JBossMQ in deploy-hasingleton/jms to use DefaultDS which was pointing to MySQL db.

          To fix the problem i simply created another copy of default-ds.xml and named it mysql-ds.xml file and datasource as MySqlDs and configured JBossMQ to use this datasource instead of DefaultDS and it worked :P

          Both MySqlDs and DefaultDS point to the same database not sure why it doesn't work with DefaultDS. Anyone has any idea?

          Thanks
