Beginning Question: TreeCache and Clustering Requirement

[cortesr]

I apologize if this question has been asked before but I searched the forum and couldn't find an answer.

Does anyone know if it's necessary for instances of JBoss to be clustered to use the TreeCache caching framework? Our current environment utilizes the NetScaler hardware-based load balancer to distribute requests thus we are not using JBoss' built-in clustering but we are starting to evaluate caching frameworks and JBossCache (i.e. TreeCache) looks like an obvious choice with the exception of the possible clustering requirement. Thanks.

No, you can run JBossCache locally, without replication

Thanks for the reply. Currently, our JBoss applications don't use transactions with Hibernate against our database. Am I right in saying that I would still have to use dummy transactions with the TreeCache in order to get replication to work across the servers, albeit without JBoss clustering?

Yes, but be aware that the Dummy TXMgr should not used in a production system
