[jboss-user] [Clustering] - JBoss Cache Replication not happening in a clustered environ

[ramesh-smx]

Hi,

We have couple of JBoss nodes set up in a clustered mode and we are testing whether the JBoss cache is getting replicated properly. The nodes are coming up properly and joining the cluster as far as we can verify. The only problem is that changes to the cache is not getting replicated between the nodes. I have attached the configuration we are using below.

Is there any way to debug the cache replication issue? Any logs that we can look at? Since we are setting this up for the first time, any help would be appreciated.

Thanks,
Ramesh
