Interacting with Oracle

Recovery Manager for Oracle User’s Guide

2.3 Interacting with Oracle

3PAR Recovery Manager interacts with Oracle database through the SQL Plus utility to perform 

the following:

Retrieve database structure information in order to create virtual copy for the database.

Interact with the Oracle database (put tablespaces (or the whole database) in and out of 

backup mode, switch logfiles) as necessary to create a consistent virtual copy.

In order to create a consistent virtual copy of an Oracle database, the database structure must 

satisfy the following requirements:

The database must be running in archive log mode and automatic archiving must be 

enabled in order to create an online virtual copy, datafile only virtual copy, or archive log 

only virtual copy.

Datafiles and archive logs must reside on separate 3PAR virtual volumes.

The online redo logs and control files should not reside on the virtual volumes used by the 

datafiles and archive logs to avoid being rolled back along with datafiles and archive logs 

virtual volumes. However, the online redo logs and control files can share the same 3PAR 

virtual volumes.

If the database files reside on Veritas VxVM volumes, datafiles and archive logs must reside 

on separate VxVM disk groups. The online redo logs and control files should reside on 

separate VxVM volumes used by the datafiles and archive logs.

If the Oracle database is an ASM managed database, the datafiles and archive logs must 

reside on separate ASM disk groups. The online redo logs and control files should not 

reside on the same ASM disk groups used by the datafiles and archive logs to avoid being 

restored when using the Recovery Manager Rollback feature. 

ASM disk groups should not be shared between different databases.

If the database is an RAC database, all RAC instances must share the same archive log 

destinations (same cluster file systems or same ASM disk groups).
