RMAN can't SET NEWNAME for datafiles added after Level 1

Question

Version: 11.2.0.3
Platform : Solaris 10
I have the most recent Level 0 , Level 1 and post-L1 Archive logs of the source DB.
I am trying restore, recover in a different machine using plain RMAN (not RMAN DUPLICATE) into a new datafile location.
After the Level 1 backup was taken, 2 datafiles (namdata01.dbf, finaldata01.dbf) were added ( this got 'recorded' on the subsequent post-L1 archivelogs )
Before I ran restore and recover, I restored the latest control file from the most recent L1
RMAN> restore controlfile from '/u01/CATALOGTST/rmanBkpPieces/SNTCDEV_L1_0cnjqk54_1_1_20120829.rmbk' ;Understandably, this control file doesn't have info about the 2 datafiles added after L1 .Wish I could restore control file from archive log :)
So, I cataloged the archive logs as well using CATALOG command.
RMAN> catalog start with '/u01/CATALOGTST/rmanBkpPieces';
using target database control file instead of recovery catalog
searching for all files that match the pattern /u01/CATALOGTST/rmanBkpPieces

RMAN> EXITDuring Recovery , RMAN applied the archive logs and managed to create the datafiles successfully. But it can't restore the datafiles to the new location specified in the SET NEWNAME location. Luckily , I had created the original path and these 2 datafiles got restored there.
RMAN can't seem enforce SET NEWNAME for datafiles added after Level 1 backup despite cataloging.
Does SET NEWNAME .... thing work only for RESTORE ?

Answer 1

RMAN> run
2> {
3> set newname for database to '/u01/app/CLONE1/oradata/sntcdev/%b' ;
4> set newname for tempfile '/u01/app/oradata/sntcdev/temp01.dbf' to '/u01/app/CLONE1/oradata/sntcdev/temp01.dbf' ;
5> restore database;
6> switch datafile all;
7> switch tempfile all;
8> recover database;
9> }RMAN executes the commands in the run block stepwise. In your case, starting from "set newname for database..." and lastly executing "recover database...".
Let me interpret it for you.
1. You restored the controlfile from the L1 backup which does not have any information about the 2 newly added datafiles. You cataloged the backuppieces and the archives to this controlfile, which means that the controlfile would now be aware that the required backups and archives are in this cataloged location.
2. You set newname for database to the desired location, thereby this command is executed restoring the database from the L0 and L1 backups. (These 2 backups do not have any information about the newly added datafiles and hence the 2 files would still not be restored).
3. You execute restore database which restores the files from L0 and L1 backup.
4. Switch datafile all, this renames all the files that were restored in the previous steps to the desired name/location that was mentioned in step 2.
5. Recover database: This is where the archivelogs come into picture. The data in the archives would be created & recovered. The newly added datafiles are now created & recovered but RMAN does not go back to STEP 2 and STEP 4 to re-execute the commands in STEP2 and STEP4 to restore it to the desired location (STEP 2) and Rename it (STEP 4). The files will have to renamed later by moving them manually to the location that you require.
So, RMAN does not execute the SET NEWNAME for datafiles which were added after the backup as the information about these files do not exist in the RMAN backuppieces.
