> We have implemented JCS RMI Remote cache to build a Primary(JCS Remote Cache Server-
1) and another Failover (JCS Remote Cache Server-2) cache servers to be used by our enterprise
Web application deployed on Weblogic cluster of 8 instances. We have JCS RMI client running
on the application instances and they need to keep a local copy of the cached object in memory
on the local JVM instances. The Remote cache gets some updates in the caches objects, ideally
it has to propagate the update event to the local caches which are registered the listener
for Remote cache. This is not working as expected. What we have seen is, the events are getting
propagated between Primary(JCS Remote Cache Server- 1) and another Failover (JCS Remote Cache
Server-2), but the same is not getting propagated to the other RMI JCS clients running on
the Weblogic cluster. Which is causing the local cached copy of the cahced objects on clients
remain stale and do not get updated when remote cache gets updated. Below is the .ccf files
for Primary(JCS Remote Cache Server- 1), Failover (JCS Remote Cache Server-2) and one of the
remote client JCS-

> We ran some small tests for a demo/POC on Windows OS and the even updates are recieved
from RMI remote JCS cache to the local client. But our deployment OS is Solaris 10 and when
we are deploying there , the events are not propagated.
