I wanted to stay away from putting in customizations like the set newname, since the process would need to be updated each time there might be a modification to the production DB. Date: Sun, 20 May 2012 09:43:11 +0200

how about use during duplicate run set newname in RMAN and set them to asm aliases?

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.
