Integrating Oracle and Data Protector

Integration Concept

Messages from the backup session are sent to the Backup Session Manager, which writes messages and information regarding the backup session to the IDB.

The Data Protector General Media Agent writes data to the backup devices.

Restore Flow A restore session can be started using:

•Data Protector GUI

•RMAN CLI

•Oracle Enterprise Manager GUI

You must specify which objects are to be restored.

A restore from the Data Protector user interface is triggered by the Data Protector Restore Session Manager, which starts the ob2rman.pl command. Ob2rman.pl prepares the environment to start the restore, and issues the RMAN restore command. RMAN checks the recovery catalog (if one is used) or the control file to gather the information about the Oracle backup objects. It also contacts the Oracle Server processes, which initialize the restore through MML. MML establishes a connection with the Restore Session Manager and passes along the information about which objects and object versions are needed.

The Restore Session Manager checks the IDB to find the appropriate devices and media, starts the General Media Agent, establishes a connection between MML and the General Media Agent, and then monitors the restore and writes messages and information regarding the restore to the IDB.

The General Media Agent reads the data from the backup devices and sends it to the Oracle Server processes through MML. The Oracle Server Processes write the data to the disks.

The concept of Oracle integration, data and the control flow are shown in Figure 1-1 on page 9, and the related terms are explained in the following table.
