Hi all,
I've a web app deployed in 4 machines behind a load balancer. Every server has 
own tomcat. The particularity of the architecture is that the webapp is 
deployed on a nfs so that the 4 servers has the same configuration.

My need is to have a cache shared between the server.

I think to configure jcs in this way (for every server):
...
jcs.region.qf=LTCP
jcs.region.qf.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
jcs.region.qf.cacheattributes.MaxObjects=2000
jcs.region.qf.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.mru.MRUMemoryCache
jcs.region.qf.cacheattributes.UseMemoryShrinker=false
#jcs.region.qf.cacheattributes.MaxMemoryIdleTimeSeconds=30
#jcs.region.qf.cacheattributes.ShrinkerIntervalSeconds=10
jcs.region.qf.cacheattributes.MaxSpoolPerRun=500
jcs.region.qf.elementattributes=org.apache.jcs.engine.ElementAttributes
jcs.region.qf.elementattributes.IsEternal=false
jcs.region.qf.elementattributes.MaxLifeSeconds=60

jcs.auxiliary.LTCP=org.apache.jcs.auxiliary.lateral.socket.tcp.LateralTCPCacheFactory
jcs.auxiliary.LTCP.attributes=org.apache.jcs.auxiliary.lateral.socket.tcp.TCPLateralCacheAttributes
jcs.auxiliary.LTCP.attributes.TcpServers=host1:1111,host2:1111, host3:1111, 
host4:1111
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1111
jcs.auxiliary.LTCP.attributes.AllowGet=true

I think in this way that any server listen on port 1111, and in the same time, 
every server look for the other listening on the same port.

What do you think?

Thank very much
Luca
