HP Application Recovery Manager software Integration guide (March 2008)

Operations on a replica (mounting, activating volume/disk groups...) described
below are dependent on or triggered by ZDB options. See the HP Application
Recovery Manager software administrator's guide for more information on these
options.
• Backup Session Manager reads an Oracle backup specification and the backup
is started on the application system.
• In the case of online backup, the database is switched to the backup mode. In
the case of an offline backup session, the database is shut down.
• The following is checked:
• The configuration for instant recovery (if this option is selected).
• If the database files are on the disk array.
• If the database files are on the same source volumes as the control file, redo
logs, or SPFILE. (In this case, an error is reported.)
• Application Recovery Manager 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.
If the location for control file copy is specified during configuration, Application
Recovery Manager makes a copy of the control file to the specified directory on
the application system. If the specified location is on a source volume, the source
volume will be replicated during the backup.
• A ZDB Agent (SSEA or SMISA) is started on the application and backup systems
and creates 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.
• Application Recovery Manager starts the procedure to prepare the replica on the
backup system. In this step, volume 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,
specified in the GUI.
• The remaining ZDB options are processed and details of the session are written
to the ZDB database. The session then finishes.
