[jboss-user] [JBossCache] - One node in two clusters?

[chrismeadows]

Is it possible for one cache node to be in two clusters? I've read in a couple of places around the JBoss website that it is possible, but haven't seen how to configure the cache in that way.

What config sections do I duplicate? 

The reason I want to do this as follows; I have a cluster in Europe and a cluster in USA. The nodes in each cluster replicate synchronously over LAN via UDP. Then I want one node of each cluster to also replicate asynchronously over WAN via TCP to the other cluster.

What config setup do I need for the nodes that are replicating both within the LAN and the WAN?  Do I duplicate the JGroup config, but then how do I relate the UDP config to sync LAN replication and TCP config to async WAN replication?

Or do I have to use a shared cache loader? I've thought about it, but that seems a tricky implementation and so doesn't feel like the right solution.

Can anyone provide any insight? Or better still, an example config file?

Thanks for any help,

Chris
