HP Data Protector A.06.11 Integration Manual page 48

This section provides only the information relevant to the Data Protector Oracle ZDB
integration.
Operations on a replica (mounting, activating volume/disk groups...) described
below are dependent on or triggered by ZDB options. See the HP Data Protector
zero downtime backup administrator's guide for more information on these options.
• In the case of an offline ZDB-to-disk+tape or ZDB-to-tape session, ob2rman.pl
shuts down and opens the database instance in mount state. For both, offline and
online ZDB-to-disk+tape or ZDB-to-tape sessions, Data Protector starts RMAN in
proxy-copy mode.
In the case of an offline ZDB-to-disk session, the database is shut down.
• Data Protector retrieves a list of files or raw disks to be included in the replica
creation from the Oracle database and starts the resolving process. The list is
used only to determine the source volumes to be replicated.
In the case of a ZDB-to-disk session, if the location for control file copy is specified
during configuration, Data Protector makes a copy of the control file to the
specified directory on the application system. This directory has to reside on a
disk array source volume.
• In the case of an online backup, the Oracle target database is switched into the
backup mode.
• ob2smbsplit or MML starts the procedure to create a replica of the source
volumes on which the database is installed.
• In the case of an online backup, the database files are taken out of the backup
mode after the replica is created.
In the case of an offline backup, the Oracle database is started by ob2rman.pl
after the replica is created.
• Data Protector (for ZDB to disk) or MML (for ZDB to tape or ZDB to disk+tape)
starts the procedure to prepare the replica on the backup system. In this step,
volume/disk groups on the backup system are enabled (UNIX systems) and, unless
the database is installed on raw disks, the mount points containing the Oracle
database files are mounted.
• A ZDB Agent then mounts the database on the backup system to the mount points
with the same names (created by Data Protector) as on the application system.
• If a ZDB-to-disk session is being performed, at this point the remaining ZDB options
are processed and details of the session are written to the ZDB database. The
session then finishes. The following steps in this description are not performed;
therefore, RMAN is not given any information about the ZDB-to-disk session.
• MML on the application system sends a request to the Data Protector data
movement agent (DMA) on the backup system to back up the datafiles to tape.
