OEM account dbsnmp locked.

 Use Case:  

We have changed passwords as part of regular DBA activity.  OEM account dbsnmp got locked after change.

 

Fix:

1. Change passwords for users sys and system
2. Run orapwd
3. In OEM, update config for sys: Setup>Security>Named Credentials
4. Change password for user dbsnmp
5. Quickly update OEM config for dbsnmp: Setup>Security>Monitoring Credentials

 

If the dbsnmp account still keeps locking, bounce the db and try steps 4 and 5 again.

 Good Luck.
