OAM: Storage not configured error in Session Management

               Receiving "Storage not configured" error popup in OAM console while accessing user session management information.  

Environment:

• OAM 11.1.2.3 BP07
• RHEL6/OEL6
• OUD 11.1.2.3

Cause:

OAM Console throws "Storage not configured" error due to couple of reasons. This might happen

• If there is no single OAM managed server up and running.
• When Admin server failed to initialize session manager with the following exception in Admin logs

Fix:

Following actions can help in the fixing the issue.

• Make sure to start the OAM Managed server before accessing the Session Management information through OAM Admin console
• If the above action doesn't work, Restart the OAM Admin Server(Weblogic Admin Server) again after having the OAM Managed server Up and Running.
