[jboss-user] [Clustering/JBoss] - Re: Lost in the documentation UDP->TCP

[giddion]

Ok to update this thread in case anyone else is looking for the same solution. I followed the post by bstansberry and modified my init script. Ended up with this run command:

  | /opt/jboss/bin/run.sh -c all -b 0.0.0.0 -g cameldev -Djboss.default.jgroups.stack=tcp -Djgroups.tcpping.initial_hosts=cameldev1:7600,cameldev2:7600
  | 

Which critically fails the server start. I looked over the default values in jgroups-channelfactory-stacks.xml and realized the fault.

Functional run command:

  | /opt/jboss/bin/run.sh -c default -b 0.0.0.0 -g cameldev -Djboss.default.jgroups.stack=tcp -Djgroups.tcpping.initial_hosts=cameldev1[7600],cameldev2[7600]
  | 

The key difference being how the ports are identifed.

Also in case it helps someone, here is my modified init script
