356.Which of the following commands will perform an active database duplication of the ORCL database

to the ORCL2 database?

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:oracleoradata eworclcontrol01.ctl',

'c:oracleoradata eworclcontrol02.ctl' set db_file_name_convert 'c:oracleoradataorcl','

c:oracleoradata eworcl' set log_file_name_convert 'c:oracleoradataorcl','c:oracleoradata eworcl';

B. Set oracle_sid=orcl

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

control_files

'c:oracleoradata eworclcontrol01.ctl', 'c:oracleoradata eworclcontrol02.ctl' set

db_file_name_convert

'c:oracleoradataorcl','c:oracleoradata eworcl' set log_file_name_convert

'c:oracleoradataorcl','c:oracleoradata eworcl';

C. Set oracle_sid=orcl rman target=sys/robert auxname=sys/Robert@orcl2 duplicate target database to

neworcl nofilenamecheck spfile set control_files 'c:oracleoradata eworclcontrol01.ctl',

'c:oracleoradata eworclcontrol02.ctl' set db_file_name_convert 'c:oracleoradataorcl','

c:oracleoradata eworcl' set log_file_name_convert 'c:oracleoradataorcl','c:oracleoradata eworcl';

D. Set oracle_sid=orcl rman target=sys/robert auxname=sys/Robert duplicate target database to neworcl

from active database nofilenamecheck spfile set control_files 'c:oracleoradata eworclcontrol01.ctl',

'c:oracleoradata eworclcontrol02.ctl' set db_file_name_convert 'c:oracleoradataorcl','

c:oracleoradata eworcl' set log_file_name_convert 'c:oracleoradataorcl','c:oracleoradata eworcl';

E. Set oracle_sid=orcl rman target=sys/robert auxname=sys/Robert@orcl2 duplicate target database to

neworcl from active database nofilenamecheck spfile set control_files

'c:oracleoradata eworclcontrol01.ctl',

'c:oracleoradata eworclcontrol02.ctl' set db_file_name_convert 'c:oracleoradataorcl','

c:oracleoradata eworcl' set log_file_name_convert 'c:oracleoradataorcl','c:oracleoradata eworcl';

Answer: E

官方参考：http://docs.oracle.com/cd/E11882_01/backup.112/e10643/rcmsynta020.htm#RCMRF90171

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。

E，正确。

For active database duplication, you must connect to the source database as TARGET and to the auxiliary instance as AUXILIARY. You must use the same SYSDBA password for both instances and must supply the net service name to connect to the AUXILIARY instance. A recovery catalog connection is optional.

DUPLICATE TARGET DATABASE TO dupdb

  FROM ACTIVE DATABASE

  PASSWORD FILE

  SPFILE

  NOFILENAMECHECK;

指定下列参数来显式控制辅助数据库的文件命名：

• CONTROL_FILES

• DB_FILE_NAME_CONVERT

• LOG_FILE_NAME_CONVERT

CONTROL_FILES='/u01/app/oracle/oradata/aux/control01.ctl',

'/u01/app/oracle/oradata/aux/control02.ctl',

'/u01/app/oracle/oradata/aux/control03.ctl'

DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/orcl',

'/u01/app/oracle/oradata/aux'

LOG_FILE_NAME_CONVERT='/u01/app/oracle/oradata/orcl',

'/u01/app/oracle/oradata/aux'
