HP 3PAR Recovery Manager 4.5.0 for Oracle on Solaris, Red Hat Linux, and Oracle Enterprise Linux User's Guide (QL226-97705, May 2014)

7 Using Remote Copy with Recovery Manager
Overview
HP 3PAR Remote Copy Software helps you safeguard against disasters by copying (synchronizing)
virtual volumes from one HP 3PAR StoreServ Storage system to another. HP 3PAR Recovery Manager
Software for Oracle is tightly integrated with HP 3PAR Remote Copy Software to specifically protect
Oracle databases by copying (synchronizing) Oracle datafiles and archive log virtual volumes
from one HP 3PAR StoreServ Storage system (local or primary) to another (remote or secondary),
and then creating a consistent snapshot image (Virtual Copy) of an Oracle database on the local
and remote HP 3PAR StoreServ Storage systems. This allows rapid recovery to any previous point
in time, in case of a disaster.
For more information on HP 3PAR Remote Copy Software, see the HP 3PAR Remote Copy Software
User’s Guide.
Recovery Manager for Oracle’s Remote Copy Requirements
Before using the Recovery Manager for Oracle Remote Copy utility, the following must be set up:
• Primary or local and secondary or remote servers must be correctly configured.
• Remote Copy links among nodes within the servers must be set up and Remote Copy targets
related to the servers must be created. Recovery Manager for Oracle only supports the
mirror_config policy (default) for the involved Remote Copy targets.
• If LVM or Symantec VxVM is used, all volumes that are in the same disk group as the datafiles
or archive log destinations must be admitted to the same Remote Copy group.
• The Remote Copy groups must be started and in synchronized status.
• For Synchronous Long Distance Remote Copy setups:
The Oracle datafile and archive log virtual volumes can be on the same or separate
Remote Copy groups.
◦
◦ Each Remote Copy group must have two targets. The same set of database volumes must
belong to two Remote Copy groups (with the same name). One group is for the
asynchronous periodic target, and the other group is for the synchronous target.
◦ The Oracle online redo log volumes must be included in one of the database Remote
Copy groups, excluding the Oracle datafile and archive log Remote Copy groups. This
allows for a successful failover if needed. If the Oracle online redo log volumes are
included in either the Oracle datafile Remote Copy group or the archive log Remote Copy
group, Recovery Manager for Oracle will fail.
• Refer to the HP 3PAR Remote Copy Software User’s Guide to set Remote Copy targets, links,
and groups.
After this is set up, a Recovery Manager for Oracle configuration file must be created. There are
two ways to create a configuration file.
On the backup server:
• Run /opt/3PAR/RMOra/bin/rmoragui to start the Recovery Manager for Oracle Graphical
User Interface (GUI).
or
• Run /opt/3PAR/RMOra/bin/rmora_config to start the Command Line Interface (CLI).
To set up the configuration file for Remote Copy, see “Creating a Recovery Manager for Oracle
Configuration File for Remote Copy Configuration” (page 64).
