Performing centralized Oracle restore and recovery of an online database
You can use the
PowerProtect Data Manager UI to perform a centralized restore and recovery of a full Oracle database backup without the control file.
Steps
In the
PowerProtect Data Manager UI, select
Restore > Assets and select the
Oracle tab.
The
Restore window displays all the databases that are available for restore.
To filter the displayed list of assets if needed, you can click the filter icon in the column heading
Name,
Status,
Protection Policy,
Host/Cluster/Group Name,
Host Type,
OS Type,
Application Name,
Last Copy, or
Network:
The
Name and
Application Name columns list the Oracle database asset names.
The
Status column lists the status as Available, Deleted, or Not Detected.
The
Protection Policy column lists the names of the protection policies for the assets.
The
Host/Cluster/Group Name column lists the hostnames.
The
Host Type column lists the host types as RAC or STANDALONE.
The
OS Type column lists the operating system as AIX or LINUX.
The
Last Copy column lists the dates and times of the backup copies within the specified date and time range.
The
Network column lists the networks that are available under the selected host or cluster.
NOTE The listed assets are the assets that have at least one copy discovered by
PowerProtect Data Manager. You can select only one asset for one Oracle host.
Select the check box next to the Oracle Server database asset for restore, and click
Restore.
The restore wizard opens the
Oracle Restore and Recovery window.
On the
Scope page, select
Online database recovery, then select
Full database recovery, and then click
Next.
This option restores and recovers the full database without the control file. The database must be in the mount state.
On the
Storage Unit Selection page page, type the name of the storage unit that contains the backup in the
Storage unit field, or select the storage unit from the menu, and then click
Next.
On the
Location page, select the preferred type of restore, and then click
Next:
Restore to original host—Specifies to restore to the original host with the displayed hostname.
If the original host is part of a RAC cluster, select the available node hostname from the list.
Restore to alternate host—Specifies to restore to an alternate host.
Select the alternate hostname from the list, and then select the required instance name.
On the
Credentials page, select one of the following options, and then click
Next:
Use the credentials set at asset level or policy level for restore
NOTE Credentials at the asset level take precedence over credentials at the protection policy level.
Select existing credentials or create new credentials for restore
Click
Set Credentials, complete the fields in the
Set Credential dialog, and then click
Save.
On the
Database Recovery Options page, select the required options, and then click
Next:
Restore To—Select
Current time or
Point in time.
The
Current time is the latest backup time in the control file.
For
Point in time, select one of the following options from the menu:
System Change Number—Type the System Change Number (SCN) in the text box.
Timestamp—Type the date and time in the text box, or click the icon to display a calendar and select the date and time.
Log Sequence—Type the log sequence in the text box.
Database Options—Select
Dry Run if you do not want to run an actual restore and recovery.
The dry run option enables a job that creates the required RMAN restore scripts in the
$RMAN_AGENT_HOME/tmp directory on the selected target host. The dry run procedure does not perform an actual restore or recovery. You can use the scripts that the dry run creates to perform a self-service restore as required.
On the
More Options page, specify the required options, and then click
Next:
Set Stream Count—Type an integer stream count in the text box, if required. The default stream count is 4. The maximum stream count is 255.
Compressed Restore—To enable restore compression and reduce the impact on the network bandwidth, select
Use PowerProtect DD Boost compressed restore.
To ensure that the restore settings are correct, review the information about the
Scope,
Storage unit,
Location,
Credentials,
Database Recovery Options, and
More Options.
To change any settings, you can click
Edit beside an information section. As an alternative, you can click
Back to access a specific page and change the settings as needed.
To start the centralized restore and recovery operation for the Oracle database, click

A status message appears with a link to the
Protection Jobs page where you can monitor the restore and recovery job.
