About Preferred Credentials

Preferred credentials simplify access to managed targets by storing target login credentials in the Management Repository. With preferred credentials set, users can access an Enterprise Manager target that recognizes those credentials without being prompted to log into the target. Preferred credentials are set on a per user basis, thus ensuring the security of the managed enterprise environment.

You can set preferred credentials for the following target types:

Hosts
Databases
Clusters
Cluster Databases (RAC databases)
Application Servers
