From the docs: http://tomcat.apache.org/tomcat-6.0-doc/config/cluster-membership.html The multicast address, in conjunction with the port is what creates a cluster group. To divide up your farm into several different group, or to split up QA from production, change the port or the address So you'll need to change the following for each cluster you wish to define. Your original configuration: <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/> How this might work: <!-- cluster Tomcat1 uses default values --> <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/> <!-- cluster Tomcat2 uses a different port --> <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45574" frequency="500" dropTime="3000"/> I've not tried this, but the documentation says that this should work. . . . . just my two cents. /mde/ --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
