This is the error I have been getting on my RMAN notifcations on my backup jobs for the last day or so. The title is exactly how the message is formatted.
~~~End Step Output/Error Log~~~ Error Log:BackupOp error writing input to commandERROR: Invalid username and/or password ~~~End Step Output/Error Log~~~
I only have 2 backup jobs and both are affected by this. Not sure how much information here is useful but what I have been looking at is the SYS account the jobs are using is not locked out.
select account_status from dba_users where username = 'SYS'; ACCOUNT_STATUS -------------------------------- OPEN
The emagent.trc log is showing this pair of lines for every backup job since the first one failed.

Restarting the DBConsole service has no affect and the errors persist.
I can manually run full and archivelog backups just fine as sysdba. I see no reason to blame RMAN since I can run the backup rman scripts just fine. I think this is just an EM issue.
