Integrating Oracle and Data Protector
Backing Up an Oracle Database
Chapter 158
Start a backup on the Oracle server using either Oracle Recovery
Manager or Oracle Enterprise Manager. See “Starting Oracle Backup
Using RMAN” on page 62.
Backup Procedure The following happens when you start a backup using the Data Protector
user interface:
1. Data Protector executes ob2rman.pl on the client. This command
starts RMAN and sends the Oracle RMAN Backup Command Script
to the standard input of the RMAN command.
2. The Oracle RMAN contacts the Oracle Server, which contacts Data
Protector via the MML interface and initiates a backup.
3. During the backup session, the Oracle Server reads data from the
disk and sends it to Data Protector for writing to the backup device.
Messages from the Data Protector backup session and messages
generated by Oracle are logged to the Data Protector database.
A backup of the Oracle recovery catalog is performed automatically
following each Oracle target database backup, unless otherwise specified
in the backup specification. Using the standard Oracle export utility, the
Data Protector ob2rman.pl starts an export of the Oracle recovery
catalog to a file which is then backed up by Data Protector.
Deleting Data from
the Recovery
Catalog
When backing up an Oracle database using the recovery catalog
database, all information about the backup, restore, and recovery of the
database is stored in the recovery catalog. This information is used by
RMAN during the restore. If you overwrite or format the media on which
this data is backed up, Data Protector exports the object from the Data
Protector database. You must manually delete the data from the recovery
catalog while logged on to RMAN. See the Oracle Recovery Manager
User’s Guide and References for detailed information about deleting data
from the recovery catalog.
Scheduling a Backup
For more information on scheduling, see the online Help index:
“scheduled backups”.
A backup schedule can be tailored according to your business needs. If
you have to keep the database online continuously, then you should back
it up frequently, including the backup of the Archived Redo Logs, which
is required in case you need a recovery to a particular point in time.
