Coherence and OC4J container integration - is it possible ?

Question

I'm planning to use Coherence as a clustered cache solution for database objects assembled from the database.
In order to do this I use a combination from event listener and invocation map, where I put a specially tailored message with connection information into the cache, then each node picks it up and spawns it's own listening process. But there is a catch: before we will put this connection message with database login/password we need to pull these values from somewhere. Currently I'm thinking about installing Coherence server as OC4J 10.1.3 cluster, which we're already using and utilizing it's features, like datasources configuration management etc.
So, the question is: is it possible to install Coherence server on OC4J app server ? Any FAQ/docs available on that ?

Hi,
Let me restate what I think you are asking to make sure we are on the same page.
What you want to do is use OC4J to manage credentials which ultimately need to
be picked up by a Coherence cluster to have access information to serve a backing
map listener that ultimately connects to a database.
If this is what you are proposing, than I would suggest that you keep the server
environments discrete (i.e. living in seperate JVMS) and have you Coherence logic
living in OC4J run as a client.
i.e. -Dtangosol.coherence.distributed.localstorage=false
Typically it is a really bad idea to overload a JVM with two types of servers by definition they
are extremely complex and will compete for a variety of resources.
