[jboss-user] [Clustering/JBoss] - Re: Cluster members don't see each other

[nitesh]

I ran the jgroups Probe utility on the cluster and this is what I found. There are two group-names "Tomcat-Cluster" and "DefaultPartition". While "Tomcat-Cluster" sees both the JBoss nodes, "DefaultPartition" only sees the local node. Obviously, there is some difference is the partition configuration between Tomcat-Cluster and DefaultPartition.

However, I'm not sure how to decode the differences, so if someone can help me, it'll be much appreciated.

Thanks,
Nitesh
