Hi,

Hope Orafaq members are doing good.

I have a clarification regarding Jvms.

My Application have four JVMs grouped together in one OC4J Instance.this will enable internal load balancing and failover of requests to application.

My question is, in ejb we have statefull and stateless sessions.

From this onwards, if i am telling anything wrong please correct me.

suppose my app is designed for statefull session.
suppose one jvm failed. as per my knowledge, the failed session will be transferred to one of the jvms which is alive.

for this type of transferring of statefull sessions, there should be a communication between JVMs.

which is the process responsible for communication between JVMs.

Also please let me know is there any pinging happening in between JVMs which belongs to the same OC4J group.

Please guide me.

Thanks,
Salih
