Session replication with Tomcat 6

[Tupak Amaru]

Hi . I am new to Tomcat and trying to implement session replication on 2 servers.
I have 2 servers:
10.0.1.3
10.0.1.4

According to Tomcat documentation I put into my server.xml the following code on 10.0.1.3:


<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2"> <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="6"> <Manager className="org.apache.catalina.ha.session.BackupManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true" mapSendOptions="6"/> <!-- <Manager className="org.apache.catalina.ha.session.DeltaManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true"/> --> <Channel className="org.apache.catalina.tribes.group.GroupChannel"> <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/> <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="auto" port="5001" selectorTimeout="100" maxThreads="6"/> <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter"> <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/> </Sender> <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/> <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/> <Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/> </Channel> <Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;"/> <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer" tempDir="/tmp/war-temp/" deployDir="/tmp/war-deploy/" watchDir="/tmp/war-listen/" watchEnabled="false"/> <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/> </Cluster>

I put the same code on 10.0.1.4 just with one change. The change is <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">

It is clear to me that I need to provide the ip addresses of the servers somewhere in this code, but I tryed to put on 10.0.1.3
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="[b]10.0.1.4[/b]"

and on 10.0.1.4
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="[b]10.0.1.3[/b]"

and it didn't help.

Can please someone advice or provide and example how should it be defined on each server?

Also does session replication means that if I upload a file to server 10.0.1.3 it will also be uploaded to server 10.0.1.4?
