Oracle Proxy-Copy Zdb Concepts - HP Data Protector A.06.11 Integration Manual

• 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 ZDB-to-disk session.
• If a ZDB-to-tape or a ZDB-to-disk+tape session is being performed, the processing
continues as follows:
• Ob2rman.pl starts the Oracle backup command RMAN on the backup
system, and then sends the Oracle RMAN Backup Command Script to the
RMAN cmdfile (input command file).
• RMAN contacts the Oracle database instance on the backup system, which
contacts Data Protector via SBT API and initiates a backup.
• The Oracle database instance on the backup system reads data from the
replica and sends it to the Data Protector General Media Agent for writing to
the backup device.
• At the end of data transfer, the backup system is disabled (filesystems are
unmounted on all platforms and volume/disk groups deactivated on UNIX
systems) and links are re-established.
• The recovery catalog and the control file are backed up automatically after
the target database backup is finished on the backup system. However, you
can disable this when creating a backup specification.
NOTE:
A replica of the archive logs is not created; therefore, the archive logs should
be backed up from the application system, following the standard Data Protector
Oracle archive logs backup procedure.

Oracle proxy-copy ZDB concepts

See the HP Data Protector zero downtime backup concepts guide for a general
description of ZDB-to-disk, ZDB-to-tape, ZDB-to-disk+tape, and instant recovery
concepts.
The Data Protector Oracle integration MML supports the Proxy Copy functionality.
This enables Data Protector to perform backup using filesystem backup methods.
Depending on the location of the Oracle control file, online redo log files, and SPFILE,
the following two options are possible:
