RMI Remote cache update events not getting propagated to JCS clients on Solaris.
--------------------------------------------------------------------------------
Key: JCS-93
URL: https://issues.apache.org/jira/browse/JCS-93
Project: Commons JCS
Issue Type: Bug
Components: RMI Remote Cache
Affects Versions: jcs-1.3
Environment: OS: Solaris 10
Application Server: Weblogic 9.2
Reporter: Brajesh Chhotan
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-
Primary(JCS Remote Cache Server- 1) cache.ccf

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.
