Integrating Oracle and Data Protector
Integration Concept
Chapter 16
The interface from the Oracle server processes to Data Protector is
provided by the Data Protector Oracle integration Media Management
Library (MML), which is a set of routines that allows the reading and
writing of data to General Media Agents.
Besides handling direct interaction with the media devices, Data
Protector provides scheduling, media management, network backups,
monitoring, and interactive backup.
Oracle Backup
Types Handled by
the Integration
Using this integration, you can perform the Oracle full and incremental
(up to incremental level 4) backup types.
With Oracle full and incremental level 0 backups all data blocks per
datafile are backed up. With Oracle incremental backup (level 1 or
higher), only the data blocks that have changed since a previous backup
are backed up.
The difference between a full backup and an incremental level 0 backup
is that the incremental 0 is a base for subsequent incremental backups.
Therefore, Data Protector always performs Oracle incremental 0 when
you select the full backup type in a backup specification.
The full backup type is not related to the number of datafiles included in
the backup, and can therefore be performed per single datafile. The data
being backed up, regardless of the backup type (full or incremental), is
selected and controlled by Oracle.
Oracle incremental backups can be differential or cumulative. By
default, Data Protector performs Oracle differential incremental
backups. By changing the default RMAN script created by Data
Protector, you can specify also a cumulative backup. For information on
differential and cumulative Oracle backups, see the Oracle Recovery
Manager User’s Guide.
NOTE Regardless of the Oracle backup type specified, Data Protector always
marks the Oracle backups as full in the Data Protector database, since
the Data Protector incremental backup concept is different from the
Oracle incremental backup concept.
A backup that includes all datafiles and current control file that belong
to an Oracle Server instance is known as a whole database backup.
