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
