OS REDHAT 4 Oracle 10g If you forget the slash in a db file convert parameter as in db_file_name_convert=("/fred/dir1/","/bill/dir1"); for an rman database duplicate you get duplicate files ! Ie /fred/dir1/system01.dbf becomes /bill/dir1/system01.dbf /bill/dir1system01.dbf Not sure WHICH is the real db file though! . -- Howard A. Latham Sent from my Nokia N97
