Hi,
I have a clustered environment which have 4 machines that are in the
same private switch. I have configured the clustering element of
server.xml as shown below :
|<Cluster
className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
clusterLogName="clusterlog" doClusterLog="true"
manager.className="org.apache.catalina.cluster.session.DeltaManager"
manager.expireSessionsOnShutdown="false"
manager.notifyListenersOnReplication="false"
manager.notifySessionListenersOnReplication="false"
manager.sendAllSessions="false" manager.sendAllSessionsSize="500"
manager.sendAllSessionsWaitTime="20">
<Membership
className="org.apache.catalina.cluster.mcast.McastService"
mcastAddr="228.0.0.4" mcastBindAddr="192.168.0.10"
mcastClusterDomain="TreeCache-Cluster" mcastDropTime="30000"
mcastFrequency="200" mcastPort="45564" />
<Receiver
className="org.apache.catalina.cluster.tcp.ReplicationListener"
tcpListenAddress="192.168.0.10" tcpListenPort="4010"
tcpSelectorTimeout="100" tcpThreadCount="6" />
<Sender ackTimeout="15000"
className="org.apache.catalina.cluster.tcp.ReplicationTransmitter"

doWaitAckStats="true" keepAliveMaxRequestCount="-1"
keepAliveTimeout="80000" queueCheckLock="true" queueDoStats="true"
queueTimeWait="true" recoverCounter="6" recoverTimeout="500"
replicationMode="fastasyncqueue" waitForAck="true" />
<Valve
className="org.apache.catalina.cluster.tcp.ReplicationValve"
filter=".*\.gif;.*\.js;.*\.css;.*\.png;.*\.jpeg;.*\.jpg;.*\.html;.*\.txt;"
primaryIndicator="true" />
<Valve
className="org.apache.catalina.cluster.session.JvmRouteBinderValve"
enabled="true" />
<ClusterListener
className="org.apache.catalina.cluster.session.ClusterSessionListener"
/>
<ClusterListener
className="org.apache.catalina.cluster.session.JvmRouteSessionIDBinderListener"
/>
<Deployer
className="org.apache.catalina.cluster.deploy.FarmWarDeployer"
deployDir="${catalina.base}/war-deploy/"

watchDir="${catalina.base}/war-listen/" watchEnabled="true" />
</Cluster>

Only two pair of machines get participated in clustering. The other two
will not respond to any messages or doesnt recognize the rest of the
members at all. I am running Tomcat 5.5.20 on FC5 and JDK 1.5. I have my
iptables shutdown and no other security options are enabled. Also I have
JBoss PojoCache running in my application. It is configured on a
different UDP address other than mcastAddress of Tomcat Server.xml's
Membership element. Can anyone lash some light on this issue ?
Thanks in advance.
