To verify the Cassandra message store installation was successful:

1. Verify the Cassandra core was created by logging in to the Cassandra administration console at:

   http://host:8983/cassandra
   

   If the administration console cannot be reached, check the system.log file on the Cassandra host for errors. By default, this file is located at /var/log/cassandra/system.log.

2. Verify the Indexed Search Converter (ISC) process launched correctly by accessing the statistics servlet at:

   http://host:8070/converter/statistics
   

   If the ISC cannot be reached, check the ISC log file for errors. By default, this file is located at /opt/sun/comms/messaging64/log/isc.log.*.

To scale your Cassandra message store deployment horizontally by adding more nodes to an existing deployment, see Messaging Server System Administrator's Guide.

For adding a node, and adding a data center, also see the Cassandra documentation at:
