Hi, Group,

I am running a disaster recovery. I take a RMAN backup to disk on Node A
(d:/backup). I moved all the RMAN backup files(datafile, autobackuped
controlfile etc) to Node B, but on Node B, I do not have disk D, only disk
C, so I put all the files to C:/backup, but RMAN keep looking for files at
D:/backup, how could I tell RMAN that the backup file is now on C:/backup,
not on D:/backup?

Thanks for your help.

You would need to UNCATALOG and CATALOG every individual backup piece.
Of course this is hardly desirable in times of disaster recovery.

Maybe Windows command-line SUBST command
could help you...

Give version next time.

With 10g it's very simple :

First you register the "new" backuppieces by letting RMAN find them
itself:

RMAN> catalog backup start with 'c:\backup';

And answer 'Y';

After that, verify that the backuppices are now registered under both
the old (d:\) and the new (c:\) pathname :

RMAN > list backup of database;

Then you unregister the old-path-registrations by letting RMAN find
out itself that they have disappeared

RMAN>crosscheck backup;
RMAN>delete expired;

Answer 'Y', and you are done.

With versions < 10g, this can only be applied to datafile copies and
archivelogs, not backup pieces. In that case you need some O/S-trick
like SUBST.
