[jboss-user] [Clustering/JBoss] - Re: Configuration for redundant ethernets

[alpheratz-jb]

Well, I have found a wrinkle...

If I run $JBOSS_HOME/probe.sh, I don't get a listing of the cluster members. The application doesn't show any errors, it just behaves/exits normally, just as it would if there were no cluster members.

Previously probe.sh gave me a listing of all the members in the cluster.

If I check a server log file, I see:

I am going to try setting the compatibility flag -Djgroups.marshalling.compatible=true on the command line in probe.sh.

My guess is that this is what happens within JBoss 4.0.5GA which "built the fix into GA."?

I did have to hack probe.sh a little: to ensure that it picked up the version of jgroups.jar from one of the cluster member's server/lib directories, rather than using the one in default/all (forget which it was now...typing at home).

Will report back.

Cheers,

Alph
