set log_file_name_convert 'c:\oracle\oradata\orcl','c:\oracle\oradata\neworcl';

B.

set oracle_sid=orcl

rman target=sys/robert auxname=sys/Robert@orcl2 duplicate target database nofilenamecheck spfile

set db_file_name_convert 'c:\oracle\oradata\orcl','c:\oracle\oradata\neworcl'

set log_file_name_convert 'c:\oracle\oradata\orcl','c:\oracle\oradata\neworcl';

C.

set oracle_sid=orcl

rman target=sys/robert auxname=sys/Robert@orcl2 duplicate target database to neworcl nofilenamecheck spfile
