Hello;1 person found this helpful
I don't have a document for exactly what you ask. However back in August somebody wanted to restore to a different server with different structure NOCATALOG.
This I have step by step :
I also have active duplicate with different structure :
Maybe these will work for you.
You should be running

CATALOG START WITH ' /u01/app/oracle/fast_recovery_area/DB1/backupset/<date>/bkps' ;
I'm beginning to think you are Superman!
No, not Superman. Just more observant in this thread.
There have been other threads where I haven't noticed information posted by the original poster and tendered inadequate advice.

Hi Hermant -
[oracle@mynewdb]$ ls -ltr /u01/app/oracle/fast_recovery_area/mynewdb/backupset/2013_01_29/
-rw-r----- 1 oracle oinstall 24248320 Jan 29 15:03 o1_mf_nnnd1_mynewdb_INC_LEVEL_0_8jhkz05w_.bkp

***--> Below I am connected to the target (source DB, not mynewdb), catalog, and auxiliary (mynewdb) <- please note that while I can connect to mynewdb as the target, it lacks a controlfile so there is little I can do with it....
RMAN> CATALOG START WITH '/u01/app/oracle/fast_recovery_area/mynewdb/backupset/2013_01_29/';
searching for all files that match the pattern /u01/app/oracle/fast_recovery_area/mynewdb/backupset/2013_01_29/
no files found to be unknown to the database
I believe CATALOG is failing to find new files as my rman target is not the new DB, but the source DB
I feel like the problem is that I am trying to do a new RMAN DUPLICATE - as such, I do not have a control file yet for the duplicate database (DUPLICATE itself will restore the control file, but only if its aware of where the backup pieces are, which requires me to CATALOG them on the new server, but I cannot CATALOG without a controlfile....)
Note that I have currently abandoned using DUPLICATE and instead I am just going to use the usual RMAN commands to restore the controlfile, after which I believe I will be able to CATALOG and restore the DB as whole, I just had my mind set on using DUPLICATE (for the first time) and figured I could do it in this situation but it looks like unless the backup locations are identical in the source and auxiliary, duplicate is not supported...

Hi Mmseberg - thanks for the info - it looks like for a normal (not active) DUPLICATE I will need the backup files in the same location as the source. As I note from your blog post, you use the same method I am using now (not DUPLICATE, just usual RMAN restore controlfile, recatalog, restore).
Very helpful post on active duplication, however, I will read more on this topic.
Sure enough, once I restored the controlfile from the backup piece and connected with the mynewdb as the target:
RMAN> CATALOG RECOVERY AREA;

channel ORA_DISK_1: SID=19 device type=DISK

So I guess the lesson learned for me is that a non-active DUPLICATE will not work unless backup pieces are in an identical location on the source and auxiliary... At least that's what it appears
Can you try with "SET DBID" and see what happens:1 person found this helpful

In 11gR2 (the version you are using), you can run DUPLICATE and specify the location of your files - the BACKUP LOCATION option. You cannot be connected to the target when you do that, but that’s usually not a big problem.
Ahhh - cool, thanks Iordan - unfortunately I'm not in a position right now to test this as I needed to commit to a conventional restore due to time constraints, but will try to use this method next time.
Ok, so the conventional RMAN restore failed (I'm an amateur, for some reason controlfile was restoring to the wrong location in spite of OMF and RESOTRE DATABASE was only restoring the incremental level 0 from a week ago in spite of the fact that all subsequent level 1s and archive logs are cataloged and were copied to target server) so I'm retrying DUPLICATE using the BACKUP LOCATION available in 11g.
Sorry to reopen, but I'm now getting this error:

Database is clearly specified in the command (DUPLICATE DATABASE TO mynewdb) so is this the right error?
Was able to try the solution provided but unfrotunately still having problems.
I should probably read every detail of the thread before I post this, but when I do a similar thing ( duplicate for standby ) my connect is :
My notes for that are here :
rman target sys/password@PRIMARY auxiliary /
I know its not the same thing, but I'm thinking only the duplicate command would be different.
True. You need a controlfile to CATALOG the backuppieces.1 person found this helpful
