Determining the local Oracle SID and Home directory in a RAC environment

3
Execute the following command, where <database_name> represents the database that is being added to the plug-in:
<node> <local Oracle SID> <local Oracle Home>
In the following example, Plug‑in for Oracle is being installed on the “faro” node, the local Oracle SID is “o10rac3,” and the local Oracle Home is “/home/o10g/db.”

Adding a database to the plug-in

Oracle SID – Enter the local SID for the target RAC database. The local SID is the instance name for the target RAC database on the node where the plug-in is installed.
Parameter File(s) Path – In a multi-instance RAC environment, the plug-in requires the usage of an SPFILE as a dynamic means of maintaining initialization parameters. The SPFILE must be stored on the shared storage in ASM. Because the SPFILE is included in the Control File Autobackups, this field should be left blank in a RAC environment.
Control File Autobackup enabled – Select this option because Control File Autobackups are required in a RAC environment.

Backing up data

Install the NetVault Backup Client on an alternate node in the RAC environment. During the installation process, be sure to use the same NetVault Machine Name that was used during the installation of the NetVault Backup Client on the original node. For example, if PROD_RAC was the NetVault Machine Name specified during the installation on the original node, PROD_RAC should be used as the NetVault Machine Name on the alternate node.
*IMPORTANT: If the relocation of the plug-in is expected to be permanent or last longer than 45 days, visit https://support.quest.com/licensing-assistance to request a relocation of the RAC Database-Based Plug‑in for Oracle license keys.
3
With the plug-in installed on the alternate node, update the Oracle SID field on the Edit Oracle Database dialog.

Restoring data in a RAC environment

During the Selecting data for a restore phase of performing RMAN restores, you might select a backup set from a node where the Oracle SID equals the Oracle SID of the instance on which the plug-in is running. But you might also select a backup set from an Oracle SID of another RAC node for which backups were performed previously. For more information about performing restores after a node failure, see Performing restores after node failure.
During the Setting restore options phase, if authentication for the target database is needed, you must set the Target Database Authentication Details to the applicable values for the local Oracle instance on which the plug-in that is performing the restore resides. For more information, see Setting Destination Details.
2
Set the ORACLE_SID environment variable to the local instance.
3
Start SQL*Plus, and connect with administrator privileges to the local instance.
6
Disable the CLUSTER_DATABASE initialization parameter for the local instance.
8
Exit SQL*Plus.
> srvctl STOP DATABASE -d <database_name> -o abort
11
Start SQL*Plus, and connect with administrator privileges to the local instance.
12
In SQL*Plus, start the local instance with the MOUNT option.
13
On the Create Restore Job - Choose Saveset page, find the latest available backup that included all the tablespaces, and click Next.
14
On the Create Selection Set page, select the Whole Database node, and click Edit Plugin Options.
15
Click the Restore Options tab, and select the applicable options:
To include read-only datafiles in the restore and recovery process, select Check Read-Only Datafiles and Restore if Necessary and Check Read-Only Datafiles and Recover if Not Current. The read-only files are included only if they are needed to complete recovery. If they are not damaged, RMAN omits them.
Perform Complete Recovery – Recovers the database to the current time, that is, to the last committed transaction available in the archived and online redo logs.
Perform Database Point-in-Time Recovery – Recovers the database to a specific point-in-time whether it be a specific time, log sequence number, or SCN.
17
On the Recovery Catalog tab, select the Use Catalog option, and specify the Recovery Catalog connection details.
18
Complete the Target Client, Schedule, and Advanced Options tabs, and submit the job.
20
Start SQL*Plus, and connect with administrator privileges to the local instance.
21
Enable the CLUSTER_DATABASE initialization parameter for the local instance.
23
Exit SQL*Plus.
