Fix ‘failed.javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated’ in OEM DC Console

Fix ‘failed.javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated’ in OEM DC Console

OEM Database control (DC) was showing ‘Connection as user grid failed. javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated’ on any occasion I was asked to specify the host credentials in OEM DC – part of Oracle 11.2 installation on OEL 5.4 x86_64.

It turned out that SSL certificate or emkey was corrupted and DB Console GUI was not unable to connect to its agent and verify the credentials (MOS 1157069.1).

Fixing the problem required re-securing the console as shown below.

  1. Stop the console

    [oracle@raclinux1 ~]$ emctl stop dbconsole

  2. Unsecure the console
