Securing agent... Failed - OEM 12c

Today I was installling cloude 12c agent on 2 nodes RAC that I got agent deployment failed on first node. While long troubleshooting I found the problem was not in the deployment.  It’s there in time synchronization between Oracle Management Server and RAC nodes. After fixing it got resolved.

Issue:

EM 12c: Agent Secure Fails with Error: "javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated"

Cause

 Time synchronization between Oracle Management Server and RAC nodes

 Solution

Fixed time on OMS and RAC nodes and retry on all nodes.
