Veritas Storage Foundation 5.1 SP1: Storage and Availability Management for Oracle (5900-1504, April 2011)

Using SmartTier for Oracle in a VVR environment
The volume tags are not replicated via VVR. This means we do not have same
storage class information at the primary and remote sites. But, we do have same
volume structure at both sites. SmartTier for Oracle policies are part of File System
metadata and hence get replicated to the remote site. VVR makes sure that, if the
primary site has a vset, the remote site also has vset with same number of volumes.
Fortunately SmartTier for Oracle policies use volume index rather than volume
tags internally. This means when a new file is created or old files are extended,
the blocks are allocated from same volume index as that of primary site. This
means the database or application after DR switch over will not fail.
Here are some good practices if you use SmartTier for Oracle at primary:
■ Manually tag the volumes in same order at the remote site and make it same
as that of the primary site.
■ Whenever you add or change storage class at the primary site make sure similar
storage class structure at the remote site.
■ Do not apply new SmartTier for Oracle policy at the remote site after
switchover. This means do not run any SmartTier for Oracle commands
■ Do not run enforce at the remote site.
About deploying Storage Foundation for Databases
(SFDB) tools with Oracle Data Guard
The SFDB tools functionality is extended to support standby databases in an Oracle
Data Guard environment.
Oracle Data Guard terminology:
■ Primary Database: Also referred to as ‘Production Database’, this database is
accessed by most of the user applications.
■ Standby Database: A standby database is a transactionally consistent copy of
the primary database.
■ Data Guard Configuration: A Data Guard configuration consists of one
production database and one or more standby databases.
■ Physical Standby Database: A physically identical copy of the primary database,
with on disk database structures that are identical to the primary database on
a block-for-block basis.
You can run the following commands on a physical standby database:
