Resolution:
This could be due to the following reasons

1. Check if you have configured the Oracle Backing store and the configurations in your .tra file are correct.

2. Check if you are using the WKA settings in your .tra file, if so please make sure that you have the tangosol-coherence-override.xml file which reflects the above WKA settings.

3. If you override the Tangosol XML Settings in your .tra file (like you specify the WKA and port), then make sure the tangosol-coherence-override.xml file has the ip address of the hostname.


for E.g.
          &ltaddress system-property="tangosol.coherence.wka1"> ipaddress </address>
          &ltport system-property="tangosol.coherence.wka1.port"> port number </port>
