Oracle Listener Cannot Accept Client Connection After Failover

Valid on Linux

Symptom:

When I use Move IP only, then by default, the Oracle listener on Replica does not accept the client connection after failover.

Solution:

This is because the Oracle listener explicitly listens to the specified IP and port. When the moving IP is moved to Replica, the connection is set up for the original production IP and is not accepted by the Oracle listener. The solution is to configure the listener to listen to the IP that you want to move.
