Recovery Manager: Release 9.2.0.0.0
connected to target database: RMAN (DBID=1237603294)
The DBID value displayed is the database identifier for the target database.
If the target database is not started, RMAN shows the following message:
connected to target database (not started)
RMAN> # the RMAN prompt is displayed
9.3.4 Starting the Database
1 Start the database using the following command:
RMAN> startup mount
This command starts an Oracle instance if it is not already started, and mounts the database but
does not open it.
If the mount was successful, then the following output is displayed:
Oracle instance started
database mounted
Otherwise, appropriate error messages are displayed, indicating the causes of failure and
suitable solutions.
9.3.5 Backing Up the Database
You can back up the database to the default disk location. The default location is OS-specific. On
Linux, the default path where backup files are stored is
$ORACLE_HOME/dbs
.
To make a full backup of the data files, control files, and the current server parameter file to the
default device type (which is the disk), use the following backup command at the RMAN prompt:
RMAN> BACKUP DATABASE;
In the above command, the FORMAT parameter is not specified, so RMAN automatically gives
each backup piece a unique name and stores it in the OS-specific default location (
$ORACLE_HOME/
dbs
on Linux).
To specify a filename for the backup piece, use the backup command with the FORMAT parameter:
RMAN> BACKUP DATABASE FORMAT’/tmp/%U’;
%U generates a unique filename.
The RMAN backup command creates a backup set, which is a logical object that contains one or
more backup pieces.
The backup command output contains the essential information about the backup, as shown in the
following example:
