A Method for viewing heartbeat IP addresses

There may be questions: the above two lines are obviously different IP addresses. Why?

The reason is:

CauseThe issue only happens in 11.2.0.1 and 11.2.0.2. when GI is starting up, if it's unable to find the private interface due to hardware/OS issue, the public IP will be used. when another node starts up and tries to join the cluster, it uses private IP and fails to communicate. solutionTo resolve the issue: 1. contact OS Admin and check why problem occurrred on the private interface. 2. after the network issue is resolved, restart GI so it will use private interface
