Hi

Is hibernate clustering support replication to two DB server?
in my current project we require clustering. same application deploy on two different domain with two DB resource.
we read about tomcat clustering. but how hibernate clustering works for replication of data. So, that two DB should be in sync.

Appreciate for help!!

Thanks in advance

Unless you use caching, using a cluster is not a problem but it's expected each application to write to the same database.
If you want to use multiple databases, you'll have to setup the databases to connect to each other and keep themselves in sync (this is usually not done, you usually want the apps to write to the single database, and then have this one possibly replicated to slaves).

Tomcat clustering is an unrelated subject.

If you use 2nd level caching, then you'll need to setup your 2nd level cache for it accordingly; explanations vary depending on the cache technology.
