• 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 is enabled if this option is selected in the GUI.
• Oracle control file, online redo log files, and SPFILE reside on the same volume
group (if LVM is used) or source volume as Oracle datafiles.
By default, instant recovery is not enabled, even if this option is selected in the
GUI. You can enable instant recovery by setting the ZDB_ORA_INCLUDE_CF_OLF,
ZDB_ORA_INCLUDE_SPF, and ZDB_ORA_NO_CHECKCONF_IR omnirc variables
to 1. See “ZDB integrations omnirc variables” on page 425.
IMPORTANT:
If you enable instant recovery by setting the above mentioned variables, note
that the control file, SPFILE, and online redo logs are overwritten during instant
recovery.
The Oracle archived redo log files do not have to reside on source volumes.
Figure 5 on page 46 shows the architecture of the Data Protector Oracle ZDB
integration. The figure illustrates the configuration, in which the backup isperformed
on the backup system. It presents the default integration behavior, where Oracle
control file, online redo log files, and SPFILE reside on different disk array source
volumes than the Oracle data files. For more information on alternative Oracle backup
and restore concepts, see “ZDB integrations omnirc variables” on page 425.
