Integrating Oracle and Data Protector

Integration Concept

 

Integration Concept

 

The Data Protector Oracle integration links the Oracle database

 

management software with Data Protector. From the Oracle point of

 

view, Data Protector represents a media management software. On the

 

other hand, the Oracle database management system can be seen as a

 

data source for backup, using media controlled by Data Protector.

Components

The software components involved in backup and restore processes are:

 

• The Oracle Recovery Manager (RMAN)

 

• The Data Protector Oracle integration software

Integration

The Data Protector Oracle Integration agent (ob2rman.pl) works with

target database:

 

• Backups (backup and copy)

 

• Recovery (restore, recovery, and duplication)

How Does the

Ob2rman.pl executes RMAN, which directs the Oracle server processes

on the target database to perform backup, restore and recovery. RMAN

 

maintains the required information about the target databases in the

 

recovery catalog, the Oracle central repository of information, and in the

 

control file of a particular target database.

 

The main information which ob2rman.pl provides to RMAN is:

 

• Number of allocated RMAN channels

 

• RMAN channel environment parameters

 

• Information on the database objects to be backed up or restored

 

For backup, ob2rman.pl uses the Oracle target database views to get

 

information on which logical (tablespaces) and physical (datafiles) target

 

database objects are available for backup.

 

For restore, ob2rman.pl uses current control file or recovery catalog (if

 

used) to get information on which objects are available for restore.

 

Using the Data Protector integration with RMAN, you can back up and

 

restore the Oracle control files, datafiles, and Archived Redo Logs.
