Verifying the status of ports
Version:
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.
-
Enter the following command: netstat -an | grep <port_number>
- If port 7000 is in the LISTEN state, Cassandra is available.
- 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.
