A. Set oracle_sid=orcl rman target=sys/robert auxname=sys/Robert@orcl2 create duplicate target database to neworcl from active database nofilenamecheck spfile set control_files '
c:\oracle\oradata\neworcl\control01.ctl',
'c:\oracle\oradata\neworcl\control02.ctl' 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';
B. Set oracle_sid=orcl
rman target=sys/robert auxname=sys/Robert@orcl2 duplicate target database nofilenamecheck spfile set control_files
'c:\oracle\oradata\neworcl\control01.ctl', 'c:\oracle\oradata\neworcl\control02.ctl' set
db_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 set control_files 'c:\oracle\oradata\neworcl\control01.ctl',

　　A， create duplicate target database to neworcl from active database ，此处多了 create。
　　B， duplicate target database，此处缺少 to neworcl from active database
　　C， 缺少 from active database。
　　D， auxname=sys/Robert ，此处缺少@orcl2。
