How to use Weblogic MulticastTest tool to debug multicast problems in cluster

If you need to test or debug cluster issue, you can use the the MulticastTest tool provided by Weblogic server installation. See the following for the command.

First of all, make sure you include $WL_HOME/wlserver_10.0/server/weblogic.jar in your CLASSPATH.
Here is the format/syntax of the command:
java utils.MulticastTest -n servername -a address [-p portnumber] [-t timeout] [-s send]
You can run this command in different terminal windows with different servername. Each window should send/receive messages to each other.
