Subject Tomcat 6 clustering problem
Date Mon, 02 Jun 2008 20:12:20 GMT

Hi Guys, 
The Tomcat 6 documentation
(http://tomcat.apache.org/tomcat-6.0-doc/config/cluster.html) says that the
Context (ServletContext, right ?) attributes are replicated across cluster
members when the below element is added in either
<tomcat-home>\conf\server.xml or <tomcat-home>\conf\context.xml file. 
<Context className="org.apache.catalina.ha.context.ReplicatedContext"/>

But actually the ServletContext attributes are not replicated across all
other cluster members!!!

The added contents in my server.xml is given below:

		<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
                
managerClassName="org.apache.catalina.cluster.session.DeltaManager"
                 expireSessionsOnShutdown="false"
                 useDirtyFlag="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="127.0.0.1"
                tcpListenPort="4001"
                tcpSelectorTimeout="100"
                tcpThreadCount="6"/>

            <Sender
               
className="org.apache.catalina.cluster.tcp.ReplicationTransmitter"
                replicationMode="pooled"/>
            <Valve
className="org.apache.catalina.cluster.tcp.ReplicationValve"
                  
filter=".*\.gif;.*\.js;.*\.jpg;.*\.htm;.*\.html;.*\.txt;"/>
			<ClusterListener 
				
className="org.apache.catalina.cluster.session.ClusterSessionListener"/>

        </Cluster>
		<Context path=""
docBase="G:\RealNetworks\apache-tomcat-6.0.16\webapps\ROOT"
crossContext="true" debug="0" reloadable="true" privileged="true"/>

And the added contents in config.xml file is given below:

<Context className="org.apache.catalina.ha.context.ReplicatedContext">

Any modifications required?
Any suggestions would be highly appreciated.
Thanks in advance.
