Tomcat-Static-Unicast-Clustering

Tomcat needs to be configured to allow for setup of cluster of two nodes over unicast. Following is section of my ${LIFERAY_HOME}/tomcat-6.0.32/conf/server.xml on server1 (replace node1 with node2 and swap location of IP_ADDRESSES and change unique_id to anything 16 bit long other than{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,2}, on server.xml in server2) which allowed for this. IP_ADDRESSES here refer to private ip addresses of server1 and server2 respectively.

================================

<Engine name="Catalina" defaultHost="localhost" jvmRoute="node1">

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="6" channelStartOptions="3">
