MDB singleton stops working

[arminhaaf]

We have a mdb singleton in out jboss as 5.1 cluster on a clustered queue using the
@Depends(jboss.ha:service=HASingletonDeployer,type=Barrier") annotation.

Sometimes we loose this singleton when shutdown/startup a node.

No more consumer is on this queue.

It did not get up again without stopping all nodes and start the cluster from scratch

what can we do to get this singleton mdb up again without restarting the whole cluster or better how can we do to avoid the problem

I think your singlton cluster was not properly configured. Pls ask AS team for help.

[arminhaaf]

Why should the cluster not correctly configured. It runs most of the time without problems. Just in special scenarios, the singleton MDB did not come up, if the node it is currently running on stopped.

The deploying and loading of MDB is beyond JBM, it should be part of AS configuration.  That's why I recommended you to ask them to get better help.
