1:59 p.m.
I've implemented a JbossCache cluster with two nodes distributed on different server.
It has a CacheLoader based on oracle.
When I applied a modification of the cache on one node, it doesn't synchronized the
other one. Following there is the xml config I used.
Where is the problem? For updating the other cluster node, I need to restart the
application using it.
