This topic describes how to use Database Backup (DBS) to restore an Oracle standalone instance.
The destination device is prepared for the restoration. For more information, see Preparations to restore Oracle standalone databases.

For more information about how to install a backup gateway, see Add a backup gateway.Note This backup gateway is installed on the destination server.

ORACLE_HOME/dbsdirectory based on the SID name. If no parameter files exist, DBS automatically creates a minimum available parameter file for you to restore the Oracle database.
Destination Directory The directory to which you want to restore the database. For more information, see Preparations to restore Oracle standalone databases. Database program directory The absolute path of
ORACLE_HOME. For more information, see Preparations to restore Oracle standalone databases.
