You must add the Oracle fully qualified domain name and the logon account name to the media server’s list of Oracle servers and authentication credentials. The media server has database access for operations on Oracle instances that are included in the authentication list. Before you start any backup or restore operations, on the computer on which the Oracle instances are installed, make sure that you use the Remote Agent Utility to configure instance information and database access.
The logon account name must have administrative rights or backup operator rights to the Oracle server. If the user name is incorrect or is not provided, or if it does not have the appropriate rights, then you cannot perform Oracle backup or restore operations to that computer.
