Viewing Flashback Database status

To view database details about a previously configured database ,  including whether FRA and Flashback Database are enabled , perform the following steps.

1
In the Navigation Pane, click Create Backup Job, and click Create New next to the Selections list.
2
In the selection tree, open the applicable client node.
3
Double-click Plug‑in for Oracle, and select the applicable database.
4
From the Actions list, select View Details.
The Details dialog box includes the following details:
•
Flash Recovery Area Destination: When FRA is enabled, this option displays the destination of the FRA.
•
Flashback Database Enabled: Indicates YES if the Flashback Database feature is enabled or NO if not.
Additionally, backups done with plug-in show a Flashback Database node for the plug-in on the Create Selection Set page when you create a restore job. The Flashback Database node lets you perform a Flashback Database instead of a restore or recovery.
5
To close the dialog box, click OK.

Flashback Database options

Selecting Flashback Database in the plug-in is equivalent to the RMAN or SQL FLASHBACK DATABASE command.

Flashback Database has the following options:

•
To Restore Point: Flashes the database to a specific restore point. A restore point is a named point that can be used as a flashback target. When you create a restore point, you are naming the current System Change Number (SCN). You can create up to 2048 named restore points and these points can either be normal or guaranteed. A guaranteed restore point is used in a Flashback Database.
Restore points can be created using the CREATE RESTORE POINT command. For more information, see Creating Normal and Guaranteed Restore Points in the Oracle Database Backup and Recovery User’s Guide.
•
To Time: Reverts the database back to its state at the time specified.
•
To SCN: Reverts the database back to its state at the specified SCN.
•
Before Time: Reverts the database back to its state one second before the specified timestamp.
•
Before SCN: Reverts the database back to its state at the system change number just preceding the specified SCN.
•
Before Reset Logs (available for Oracle 10.2.x and later versions only): Rewinds the database back to the SCN just before the RESETLOGS happened.

Flashback Database restrictions

There are two restrictions on selecting Flashback Database:

•
Whole Database and Flashback Database nodes cannot be selected at the same time. If selected, the restore job fails and the NetVault Backup binary logs show an error message:
Cannot select 'Whole Database' and 'Flashback Database' at the same time.
•
On the Create Selection Set page, Flashback Database cannot be selected at the same time as other nodes such as Parameter File, Control Files, Tablespaces, and Datafiles. If selected, the restore job fails and the NetVault Backup binary logs show an error message:
Restore Selections Error. Cannot select 'Flashback Database' and Individual Datafiles at the same time.
