Performing disaster recovery in a RAC environment

If your goal is to create a new copy of your target database for ongoing use on a standby RAC environment or independent RAC environment, do not use these procedures. Instead, use the Duplicate Database backup type, which is designed for this purpose. For more information, see Duplicating a database in a RAC environment.
For variations on the following disaster recovery procedure, refer to Performing Disaster Recovery in the Oracle Database Backup and Recovery Advanced User’s Guide.
Oracle RAC environment in place – You must have a properly configured Oracle RAC environment that matches the configuration as specified Performing User Managed backups. In addition, the same version of the Oracle database software must be installed in the RAC environment as it existed on the damaged RAC environment. The ORACLE_HOME should be identical on both the original and new node. You do not have to create the database, but you do need to configure Oracle Net Services and ASM for shared storage.
NetVault Backup software and the Plug‑in for Oracle installed – The same version of NetVault Backup software and the plug-in must be installed on one of the nodes in the RAC using the same NetVault Machine Name as previously defined for the RAC environment. Ensure that the plug-in default attributes are defined as specified in Configuring default attributes.
DBID of the source database identified – Identify the DBID of the damaged database. If the DBID was not recorded as part of the initial plug-in installation, the DBID can be obtained by examining the NetVault Backup binary logs for RMAN-based backups of the source database. The DBID is also available on the Details dialog or the Backup Contents tab.
Default Location for SPFILE must exist – The default location in the ASM shared storage must exist before executing the following steps. Failure to ensure that the default location exists will result in an ORA-17502 Failed to create file error during the SPFILE restore. Additionally, the SPFILE location should be detailed in the PFILE with the SPFILE parameter.
Backups of all tablespaces made available – Make sure that you have the latest backups of all the tablespaces.
SET DBID <DBID>;

9
On the Create Restore Job - Choose Saveset page, find the latest available backup that included all the tablespaces, and click Next.
10
On the Create Selection Set page, navigate to the source NetVault Backup Client and database, select the Whole Database node, and click Edit Plugin Options.
11
Click the Restore Options tab, and select the Check Read-Only Datafiles and Restore if Necessary and Check Read-Only Datafiles and Recover if Not Current options to include read-only datafiles in the restore and recovery process.
12
Because recovery must be performed in a disaster recovery scenario, on the Perform Recovery tab, select Perform Database Point-in-Time Recovery.
13
On the Recovery Catalog tab, clear the Use Catalog option.
14
Complete the Target Client, Schedule, and Advanced Options tabs, and submit the job.

Performing restores after node failure

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 of 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.
During the Selecting data for a restore phase of performing RMAN restores, select the backup set from the node on the Create Selection Set page where the Oracle SID equals the Oracle SID of the instance where the plug-in was originally installed before the relocation.
During the Setting restore options phase, set the Target Database Authentication Details to the appropriate values for the local instance on the alternate node where the plug-in now resides. For more information, see Setting Destination Details.
