3.建立輔助例項的密碼檔案(這裡輔助例項名為dup) ,在目的主機上為輔助例項建立密碼檔案可以有以下選項:
.手動建立密碼檔案,對於duplicate ... from active database有額外的要求。必須使用SYS使用者ID並且密碼必須與原資料庫的密碼相匹配。當想要使用單獨的密碼來建立密碼檔案時因此可以啟動輔助例項並使用它來連線原資料庫。

.在執行duplicate ... from active database命令時指定password file選項,在這種情況下,RMAN將原資料庫的密碼檔案複製到目的主機上並且覆蓋輔助例項已經存在的密碼檔案。如果原資料庫密碼檔案有多個密碼且你想讓它們在副本資料庫中使用時這種技術是非常有用的。

[oracle11@jingyong1 dbs]$ orapwd file=/u03/app/oracle/11.2.0/db/dbs/orapwdup password=system entries=10;

[oracle11@jingyong1 dbs]$ ls -lrt orapwdup
-rw-r----- 1 oracle11 oinstall 2560 Jun  5 09:40 orapwdup

4.建立輔助例項網路連線,修改監聽檔案,使用靜態監聽來監聽輔助例項

給輔助例項增加網路服務名

[oracle11@jingyong1 admin]$ vi tnsnames.ora
# tnsnames.ora Network Configuration File: /u03/app/oracle/11.2.0/db/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

dup =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.11)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = dup)
      (UR = A)
    )
  )

5.建立輔助例項的引數檔案,初始化引數檔案的目錄和內容依賴於給複製檔案命名選擇的策略。可以選擇建議的技術來對原主機和目的主機使用相同的命名策略。因此對於Oracle RAC環境,對於原主機和目的主機可以使用相同的ORACLE_SID。在引數檔案中將db_name設定為任意值,db_name是唯一必須設定的引數。建立引數檔案有以下選項:
.為輔助例項來建立文字引數檔案,初始化引數檔案的儲存目錄是在主機上作業系統特定的預設目錄。例如,在Linux和UNIX中預設引數檔名是ORACLE_HOME/dbs/initORACLE_SID.ora,在Windows平臺上引數檔名是ORACLE_HOME\database\initORACLE_SID.ora

.在執行duplicate命令時指定spfile子句。duplicate ... spfile技術最簡單,因為在執行復制時RMAN自動將原資料庫的spfile檔案複製到輔助例項或從備份中還原spfile檔案。如果在輔助例項上存在spfile檔案,那麼RMAN就會覆蓋它。

[oracle11@jingyong1 dbs]$ vi initdup.ora
db_name=dup
db_unique_name=dup
control_files= /u03/app/oracle/oradata/dup/control01.ctl
remote_login_passwordfile=exclusive
compatible = 11.2.0.4.0
db_block_size=8192
sga_target=300M
sga_max_size=300M
pga_aggregate_target=32M
db_file_name_convert=('/u03/app/oracle/oradata/db/','/u03/app/oracle/oradata/dup/')
log_file_name_convert=('/u03/app/oracle/oradata/db/','/u03/app/oracle/oradata/dup/')

6.啟動輔助例項,啟動SQL*Plus並使用sysdba許可權連線到輔助例項。將輔助例項啟動到nomount狀態(如果引數檔案在預設目錄中startup命令不需要pfile引數)。注意:確保輔助例項使用文字引數檔案來啟動而不是SPFILE引數檔案。不要建立控制檔案或試圖mount或open輔助例項。

[oracle11@jingyong1 dbs]$ export ORACLE_SID=dup

7.在目標主機(執行被複制資料庫的主機)配置輔助例項的網路服務名

[oracle11@oracle11g admin]$ vi tnsnames.ora
dup =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.11)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME =dup)
      (UR=A)
    )
  )

[oracle11@oracle11g admin]$ sqlplus /nolog

Copyright (c) 1982, 2013, Oracle.  All rights reserved.

SQL> conn sys/system@dup as sysdba
Connected.

8.載入或開啟目標資料庫,如果RMAN連線到原資料庫作為目標資料庫,那麼原資料庫為了執行復制必須設定為合適的狀態。如果原資料庫例項沒有mount或open,那麼將原資料庫mount或open。如果執行active database複製,那麼確保滿足下面額外的條件:
-如果原資料庫open,那麼必須啟用歸檔
-如果原資料庫沒有open,那麼資料庫不需要執行例項恢復
由於原資料庫啟用了歸檔所以可以將原資料庫啟動到open狀態

[oracle11@oracle11g ~]$ sqlplus / as sysdba

9.執行duplicate命令,如果沒有配置自動通道,那麼至少手動分配一個輔助例項。如果是使用PFILE引數檔案啟動輔助例項需要指定pfile引數檔案,且pfile引數檔案必須儲存在執行RMAN執行復制的主機上。複製命令沒有指定資料庫名。使用database關鍵字而不指定資料庫名,duplicate將從備份中獲得資料庫名和DBID。如果在backup location目錄中一個資料庫有多個備份將會顯示錯誤。使用backup子句來識別沒有目標資料庫和恢復目錄的複製型別。until time選項用來指定恢復目標時間,它是唯一能與backup location子句一起使用的選項。因為副本資料庫和原資料庫檔案的檔名相同所以要指定nofilenamecheck選項:

[oracle11@oracle11g ~]$ rman auxiliary sys/system@dup
