NetVault Plug-in for Oracle 12.3

Registering the target database

The first step in using a Recovery Catalog with a target database is registering the database in the Recovery Catalog.

After making sure that the Recovery Catalog database is open, connect RMAN to the target database and Recovery Catalog database.

For example, issue the following command to connect to the catalog database.

> rman TARGET / CATALOG rman/<password>@<connect_identifier_for_catalog>

If the target database is not mounted, mount or open it:

STARTUP MOUNT;

RMAN creates rows in the catalog tables to contain information about the target database. RMAN then copies all pertinent data about the target database from the Control File into the catalog, synchronizing the Catalog with the Control File.

Verify that the registration was successful.

REPORT SCHEMA

Registering multiple databases in a Recovery Catalog

You can register multiple target databases in a single Recovery Catalog, if they do not have duplicate DBIDs. RMAN uses the DBID to distinguish one database from a different database.

In a Data Guard environment, only the primary database is registered in the Recovery Catalog.

Enabling Control File Autobackups

Control File Autobackups are required for disaster recovery with the plug-in. For more information on Control File Autobackups, see Reviewing the Control File backup types. For more information on multi-instance RAC databases, see Enabling Control File Autobackups in a RAC environment.

You can turn on the Autobackup feature by running the following commands from the RMAN command-line utility:

After making sure that the Recovery Catalog database is open, connect RMAN to the target database and Recovery Catalog database.

For example, issue the following commands to connect to the catalog database:

> rman TARGET / CATALOG rman/<password>@<connect_identifier for catalog>

Optionally, you can use the following commands to change the autobackup format. The default format for Control File Autobackup is “%F”.

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE

TYPE <device type> TO '<string>'

– or –

SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE <device type> TO '<string>'

The SET CONTROLFILE AUTOBACKUP FORMAT command overrides the configured autobackup format in the current session only.

If you modify the default format for the autobackups, you must specify the same format during a restore.

Configure the default device type to “SBT_TAPE”.

CONFIGURE DEFAULT DEVICE TYPE TO 'SBT_TAPE';

Enable Control File Autobackups.

CONFIGURE CONTROLFILE AUTOBACKUP ON;

Confirm that Control File Autobackups are enabled by reviewing the RMAN configuration settings.

Enabling Flashback Database

Flashback Database lets you rewind an Oracle database to a previous time to correct problems caused by logical data corruptions or user errors as long as the datafiles are intact. For more information on Flashback Database, see Oracle Flashback technology.

Flashback Database uses its own logging mechanism, creating Flashback Logs and storing them in the FRA. You can only use Flashback Database if Flashback Logs are available. To take advantage of this feature, set up your database in advance to create Flashback Logs.

Setting a retention target

Determining whether Flashback Database is enabled

Start SQL*Plus, and connect with administrator privileges to the database.

sqlplus SYS/<password>@<connect_identifier> AS SYSDBA

From the SQL> prompt, enter:

select flashback_on from v$database;

The output shows the status of Flashback Database.

To enable Flashback Database, first configure an FRA. For more information, see Enabling the Flash Recovery Area in the Oracle Database Backup and Recovery User’s Guide.
