To all clustering gurus: problem when deploying ear into has

paulpark Jan 18, 2008 12:22 PM

Hi all,

Any help would be greatly appreciated!!!

We have a cluster of 2 nodes, A and B using JBoss AS 4.0.5GA. I have a packaged ear containing MDB that I want to deploy as a singleton, so I just copied ear file into deploy-hasingleton dir.

1) started A and B, ear deployed in A, but not B as expected
2) shut down A and B does not become master (problem)

Is there anything else I have to configure to get ear file to work as a singleton?

Thanks

Just found that one of the servers had a firewall enabled on one of them, so the UDP packets from JGroups to enable clustering was being rejected.
