About Credentials for Performing Backup and Recovery

When using Enterprise Manager, you must have the proper credentials to perform some of the configuration tasks for backup and recovery, to schedule backup jobs, and to perform recovery. The following credentials may be required:

• The Oracle database administrator user you use when you log in to Enterprise Manager

• The host operating system user whose credentials you provide when performing backup and recovery tasks

To perform or schedule RMAN tasks, you must either log in to Enterprise Manager as a user with SYSDBA privileges, or provide host operating system credentials for a user who is a member of the dba group. The host operating system user must also have execute permission for the RMAN command-line client.

For tasks requiring host operating system credentials, a Host Credentials form appears at the bottom of the page used to perform the task. Enterprise Manager uses the credentials when it invokes RMAN to perform jobs you requested or scheduled.

The Host Credentials form always includes an option labeled Save as Preferred Credential. If you select this option before performing your action, then the provided credentials are stored persistently for the currently logged-in Oracle database user. The preferred credentials are reused by default whenever you log in as that user and perform operations requiring host credentials.
