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).
Refer to

How Remote Copy Works
A Remote Copy configuration typically involves two HP 3PAR 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
storage systems are always in sync. However, the copy of the Oracle database on the remote
server is considered inconsistent and can only be 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 storage systems. The database is placed in backup
mode prior to the snapshot being taken. See
Figure 3 Synchronous Mode Remote Copy Configuration
In asynchronous periodic mode, Recovery Manager for Oracle can help to initiate a synchronization
between the database virtual volumes between two HP 3PAR storage systems and create a consistent
database virtual copy on the local and remote systems. See
