Hi

The Following was done for the Clustering  (2 tomcats )

Values 	TOMCAT5523_I 	TOMCAT5523_II

	
Startup  	8081 	8082
ShutDown 	8007 	8008

	
APJ  	8009 	8010
TCP Listener 	4001 	4002
tcpListenAddress 	auto 	auto
jvmRoute 	node01 	node02


Delpoyment of a war file on TOMCAT5523_I  displays in console as
