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 61) .
How Remote Copy Works
A Remote Copy configuration typically involves two HP 3PAR StoreServ Storage systems: a local
or primary system and a remote or secondary system. The synchronization between the local and
remote systems can be either synchronous or asynchronous periodic mode.
In synchronous mode, Oracle database virtual volumes between the local and remote HP 3PAR
StoreServ Storage systems are always in synchronization. However, the copy of the Oracle database
on the remote server is considered inconsistent and can be only used for crash recovery. Recovery
Manager for Oracle can be used to create a consistent snapshot image (Virtual Copy) of the
database virtual volumes on the local and remote HP 3PAR StoreServ Storage systems. The database
is placed in backup mode prior to the snapshot being taken. See
Figure 4 (page 119)
Figure 4 Synchronous Mode Remote Copy Configuration
In asynchronous periodic mode, Recovery Manager for Oracle can help to initiate synchronization
between the database virtual volumes between two HP 3PAR StoreServ Storage systems and create
a consistent database Virtual Copy on the local and remote systems. See
Figure 5 (page 120) .
