I realise that this was the case with pre 10gR2 RMAN backups, but the latest 10gR2 RMAN now records information about tempfiles, eg,

[1020]$ rman nocatalog

Recovery Manager: Release 10.2.0.1.0 - Production on Thu Nov 3

RMAN> connect target /

connected to target database: DUP (DBID=877644596) using target database control file instead of recovery catalog

RMAN> report schema ;

So, when duplicating a database with a tempfile, it appears that you need the following extra line

set newname for tempfile 1 to '/a01/o/DUP/temp.dbf';

Otherwise you will get this error message:

RMAN-05517: temporary file /a01/o/DUP/temp_01.dbf conflicts with file used by target database

So, I can duplicate the database without error until you need to access the tempfile. So if the added functionality for tempfiles is now included it seems strange that you still need to drop and recreate the tempfile?
