Oracle backup set ZDB concepts
See the HP Data Protector zero downtime backup concepts guide for a general
description of ZDB-to-disk, ZDB-to-tape, and ZDB-to-disk+tape and instant recovery
concepts.
With the Oracle backup set ZDB method, the entire data to be backed up is provided
to Data Protector through the Oracle API—the data is streamed through the Data
Protector Oracle integration MML.
Depending on the location of the Oracle control file, online redo log files, and SPFILE,
the following two options are possible:
• Oracle control file, online redo log files, and SPFILE reside on a different volume
group (if LVM is used) or source volume than Oracle datafiles.
By default, instant recovery for such a configuration is enabled.
• Oracle control file, online redo log files, SPFILE reside on the same volume group
(if LVM is used) or source volume as Oracle datafiles.
