Using RMAN types of recovery in a non-RAC environment

Oracle® Customer Support has advised that a Control File restore is required.
3
Use SET DBID to set the database identifier for the target database.
SET DBID <Source_DBID>;
Running the ALTER DATABASE OPEN RESETLOGS command from RMAN versus SQL*Plus resets the target database automatically so that you do not have to run a RESET DATABASE. By resetting the database, RMAN considers the new incarnation as the current incarnation of the database. If you run ALTER DATABASE OPEN RESETLOGS from SQL*Plus and do not follow it with a RESET DATABASE at the RMAN prompt, RMAN refuses to access the Recovery Catalog. RMAN refuses because it cannot distinguish between a RESETLOGS operation and an accidental restore of an old Control File.

Recovering individual datafiles and tablespaces to the same server

This type of recovery is performed when the database is open, but some of the datafiles are damaged. This recovery is useful when you want to recover the damaged tablespace, while leaving the database open so that the rest of the database remains available. You can only perform Complete Recovery when restoring and recovering individual datafiles or tablespaces. PIT Recovery is not available for individual datafiles or tablespaces. Enabling PIT Recovery causes the restore job to fail. Following is an overview of the process to recover individual datafiles or tablespaces:
1
On the Create Selection Set page, select the damaged datafiles or tablespaces from the latest available backup of the tablespace, and click Edit Plugin Options.
2
Click the Restore Options tab, and select the Alter Tablespaces Offline Before Restore and the Alter Tablespaces Online After Restore options.
3
On the Perform Recovery tab, select the applicable options:
NOTE: If you select the Perform Database Point in Time Recovery option, the restore job fails.
To delete the restored archive logs that Oracle® deems unnecessary, select the Delete Restored Archive Logs No Longer Needed option.
4
Complete the Target Client, Schedule, and Advanced Options tabs, and submit the job.

Recovering Whole Database to same server

1
On the Create Restore Job — Choose Saveset page, find the latest available backup that included all the tablespaces, and click Next.
2
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.
3
Click the Restore Options tab, and select the applicable options:
To include read-only datafiles in the restore, select Check Read-Only Datafiles and Restore if Necessary.
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 Point-in-Time Recovery: Recovers the database to a specific point whether it be a specific time, log sequence number, or SCN.
5
On the Perform Recovery tab, select these additional options, if applicable:
To include read-only datafiles in the recovery process, select 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.
To delete the restored archive logs that Oracle® deems unnecessary, select Delete Archive Logs No Longer Needed.
6
On the Post Recovery tab, select Open Database after Recovery and Read Write and Reset Logs to open the database automatically in read-write mode and reset the online logs.
7
Complete the Target Client, Schedule, and Advanced Options tabs, and submit the job.
