ASM is generating new and different file names each time, right? If I do not
have an ASM instance, I can remove the 'temp' files for the temporary
tablespace only, and RMAN just writes over all the existing data files and
opens the database -- because they have the same name. Of course, I could just
as easily remove all the files.
Sidney Chen probably hit it on the head...,

Subject: ASM Datafiles and RMAN duplicate db
Folks,
I am duplicating my prod db every night and recently started using ASM
diskgroups for the auxiliary database instance. I've noticed that each time
duplicate db runs, a new set of datafiles are created, leaving the datafiles
from the previous run behind. I've set the db_create_file_dest to the ASM
diskgroup. I was wondering if there would be a way to easily reuse / remove
the old files, since its filling up my diskgroup.
I'm investigating changing the datafile name format, so that it overwrites the
files each time, instead of appending the incarnation number at the end that
makes every file unique.
I'd appreciate any tips / pointers to resolve this issue.
Regards,
IM
