Session replication using apache+mod_jk+tomcat(5.5.28-veriosn of tomcat)
Hi,
I have two tomcats running on two diffrent system connected via LAN, and they are load balanced via apache+mod_jk. The load balance set up is working but have issue with session replication. When any one of the tomcat gets down the session is not replicated . The clustered configuration that i have added to the server.xmol file is given below : <Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" managerClassName="org.apache.catalina.cluster.session.DeltaManager" expireSessionsOnShutdown="false" useDirtyFlag="true" notifyListenersOnReplication="true"> <Membership className="org.apache.catalina.cluster.mcast.McastService" mcastAddr="228.0.0.4" mcastPort="45564" mcastFrequency="500" mcastDropTime="3000"/> <Receiver className="org.apache.catalina.cluster.tcp.ReplicationListener" tcpListenAddress="auto" tcpListenPort="4001" tcpSelectorTimeout="100" tcpThreadCount="6"/> <Sender className="org.apache.catalina.cluster.tcp.ReplicationTransmitter" replicationMode="pooled" ackTimeout="15000" waitForAck="true"/> <Valve className="org.apache.catalina.cluster.tcp.ReplicationValve" filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;"/> <Deployer className="org.apache.catalina.cluster.deploy.FarmWarDeployer" tempDir="/tmp/war-temp/" deployDir="/tmp/war-deploy/" watchDir="/tmp/war-listen/" watchEnabled="false"/> <ClusterListener className="org.apache.catalina.cluster.session.ClusterSessionListener"/> </Cluster> ============================================================================= I have also added the below content to the ROOT.xml file as given below: < Context path="" debug="0" reloadable="true" cookies="true" crossContext="false" privileged="false" > ============================================================================== Then i have added <distributable/> to the file web.xml in location webapps/ROOT/WEB-INF/ ============================================================================= Please guide me to the right path and help me to set this tomcat set up. |
I'm afraid I don't have a solution, but you would be far more likely to find one if you had posted this in Linux - Networking rather than Linux - Newbie, as it's quite an advanced question and one specifically about networking.
Perhaps you could ask a moderator to move it :) |
