mkdir -p  /u01/app/oracle/oradata/dup01/

   mkdir -p  /u01/app/oracle/admin/dup01/adump

2. 将源端的密码文件$ORACLE_HOME/dbs/orapwtest01拷贝至目标端$ORACLE_HOME/dbs/， 改名
    scp oracle@192.168.13.128:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwtest01 /u01/app/oracle/product/11.2.0/dbhome_1/dbs
   mv /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwtest01  /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwdup01

3. 创建pfile, $ORACLE_HOME/dbs/initdup01.ora, 内容很简单：
   db_name=dup01
4. active需要静态监听， listener.ora文件内容
  # listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
  # Generated by Oracle configuration tools.
SID_LIST_LISTENER =
  (SID_LIST =
    (
     SID_DESC =
      (GLOBAL_DBNAME = test01)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = test01)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = dup01)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = dup01)
    )
  )


LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )


ADR_BASE_LISTENER = /u01/app/oracle


5. 源端配置两个TNS(tnsnames.ora)：

  TEST01 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test01)
    )
  )
dup01 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.13.129)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = dup01)
    )
  )

6. 将目标端启动至nomount状态
  
7.源端登录：
  rman target sys/sys@test01 auxiliary sys/sys@dup01
  DUPLICATE DATABASE TO dup01 FROM ACTIVE DATABASE SPFILE NOFILENAMECHECK;

如果没出现问题，就可以看到如下输出：
此处省略若干行....
sql statement: alter system set  db_name =  ''DUP01'' comment= ''Reset to original value by RMAN'' scope=spfile


sql statement: alter system reset  db_unique_name scope=spfile
