How to update scheduler job credentials in oracle enterprise manager? I have a job scheduled in oracle 11g which runs on daily basis. Job is running with User "user_dba" (unix server user). The job is failing from the day I changed the password for the user "user_dba". I navigated to scheduler jobs in OEM and found the credential name "user_dba_credential". The job is failing because this named credential still has old password where as I have changed the password. So can anyone please tell me how to update the password in the "user_dba_credential" to my new password via OEM?

Thanks in advance.
In Oracle Enterprise Manager Cloud Control 12c you can edit the named credentials by navigating to Setup > Security > Named Credentials

In Oracle Enterprise Manager 11g Database Control you should look at Preferences > Preferred Credentials, here is the documentation.
