8.1.2 Rollback Using Database Read-Write Virtual Copy 8.4

Recovery Manager provides a way to rollback a database to a point-in-time image by

promoting a read-only or read-write virtual copy back to the base (database) virtual volumes.

The base (database) virtual volume must not be exported to any host during the rollback

process. In other words, the database LUNs of the corresponding database virtual volumes

must be removed from the database host prior to the rollback process. Once the rollback

process completes, the database LUNs can be exported back to the database host.

NOTE: When using rollback utility with Remote Copy configuration. The virtual

copy will rollback on the secondary InServ. Please refer to the InForm Users Guide

to reverse the Remote Copy configuration. If a virtual copy is a standby database,

the base virtual volumes of the standby database

(not the primary database) is rolled back.
