Jboss Horizontal Cluster

[John Simpson]

Can anyone give advice/direction where to find info on horizontal clustering of JBoss AS? I am not referring to multiple nodes forming 1 cluster, but multiple clusters and their respective communications.

I have successfully created and deployed a single cluster, (with multiple nodes) I now need information regarding the communications between JBoss clusters.

Thanks in advance!

John,

I haven't deployed a Horizontal Cluster, but we do have a single, 2 node cluster that is having issues.

Did you cluster HA and Web Sessions? Our issue manifests itself by one side of the cluster quickly running OutOfMemory, then the other side almost right after does the same thing.

We are also seeing the error below in the logs. We are using JBoss 4.0.5, Hibernate 3.0. Did you have any issues with your cluster?
