In Pega Platform 7.2.1 and later, check if ports 7000 and
9042 listen to an IP address which is accessible from the other nodes.
For the embedded Cassandra configuration, the Pega Platform-spawned
Cassandra JVM needs to have 7000 and 9042 ports open.
For the external Cassandra configuration, Pega Platform only needs the
Cassandra machines to have port 9042 open. However, the external Cassandra machines also
need port 7000 open between them so that they can communicate between themselves.
For more information, see Cassandra overview.
Result: The status of the port appears:
- Enter the following command: netstat -an | grep
- If port 7000 is in the LISTEN state, Cassandra is
- If port 7000 is in the LISTEN and
ESTABLISHED states, other nodes are connected
to this machine's Cassandra instance.
- If port 9042 is in LISTEN mode, the DataStax driver
clients can access the node for queries.
