Resolution:
Following are the steps to use WellKnownAddress Tangosol feature in TIBCO BusinessEvents (BE) 2.0-
1) Place the attached "tangosol-coherence-override.xml" in $TIBCO_HOME/be/2.0/hotfix/lib folder

2) Edit this file to modify the following properties as per your environment -
      &ltwell-known-addresses>
        &ltsocket-address id="1">
          &ltaddress system-property="tangosol.coherence.wka1"&gt10.105.96.117</address>
          &ltport system-property="tangosol.coherence.wka1.port"&gt9005</port>
        </socket-address>
        &ltsocket-address id="2">
       &ltaddress system-property="tangosol.coherence.wka2"&gt10.107.206.50</address>
       &ltport system-property="tangosol.coherence.wka2.port"&gt9005</port>
        </socket-address>
      </well-known-addresses>
You can add additional nodes here if you have more than two nodes.

3) Now to modify these properties using Administrator (while deploying), you can use the following properties in the .tra file-
java.property.tangosol.coherence.wka1=nshetty-lt
java.property.tangosol.coherence.wka1.port=9001
java.property.tangosol.coherence.wka2=ae-sol9
java.property.tangosol.coherence.wka2.port=9001

How do we use the WellKnownAddress (WKA) Tangosol feature in TIBCO BusinessEvents (BE) 2.0 to use the unicast address instead of multicast address?
