Parameters for self-service Oracle backups and restores

For a self-service Oracle backup or restore, you must set the required Oracle RMAN agent parameters in the backup or restore RMAN script. The BACKUP_HOST, RMAN_AGENT_HOME, and STORAGE_UNIT parameters are mandatory. You can set other optional parameters for specific operations.

To prepare for self-service backups and restores of Oracle databases, review the following information about the supported Oracle RMAN agent parameters.

NOTE:In the RMAN script, you must set the parameters by using the SBT_PARMS or ENV option in the ALLOCATE CHANNEL line.

Table 1. Parameters for self-service Oracle backups and restoresTable of parameters for self-service Oracle backups and restores
Oracle RMAN agent parameter	Description	Default and valid values
BACKUP_HOST	Mandatory. Specifies the hostname of the DD system or the DD Boost-over-Fibre Channel (DFC) service name.	Undefined (default). Valid DD system hostname or DFC service name. NOTE:The value can be a DFC service name if you must run the backup or restore over Fibre Channel.
DBUNIQUE_NAME	Mandatory for a self-service backup in an Oracle Data Guard environment. Specifies the Oracle DB_UNIQUE_NAME value of the Oracle database that is backed up. You can obtain the DB_UNIQUE_NAME value by running the SQL query `SELECT DB_UNIQUE_NAME FROM V$DATABASE`.	Undefined (default). Valid DB_UNIQUE_NAME value of the database that is backed up. NOTE:The specified value is case-sensitive.
DDBOOST_COMPRESSED_RESTORE	Optional for a restore. Specifies whether the Oracle RMAN agent performs a compressed restore of the backed-up data from the DD system. A compressed restore uses less bandwidth by restoring the backed-up data in a compressed form from the DD system to the application host.	FALSE (default) = Perform an uncompressed restore. TRUE = Perform a compressed restore.
RMAN_AGENT_HOME	Mandatory. Specifies the installation directory for the Oracle RMAN agent.	$HOME/opt/dpsapps/rmanagent (default). Valid complete pathname of the Oracle RMAN agent installation directory. NOTE:The specified directory pathname must not end with a slash (/).
STORAGE_UNIT	Mandatory. Specifies the name of a storage unit on the DD server to use for the backup or restore operations with the Oracle RMAN agent.	Undefined (default). Valid directory name of the storage unit on the DD system, without the /data/col1 prefix. NOTE:The specified name is case-sensitive.
