1、環境介紹：

主機1：

作業系統	REDHAT5.5	IP地址	172.16.1.120
主機名	sigle	資料庫版本	10.2.0.4
資料庫名	orcl	DBID	1305151947
catalog	win_yjr	catalog使用者	sigle/sigle

主機2：

作業系統	REDHAT5.5	IP地址	172.16.1.121
主機名	clone_sigle	資料庫版本	10.2.0.4

本次試驗的資料庫系統檔案儲存採用raw方式，因此在進行復制前，為了確保恢復的有效性，已使用dd命令將clone_sigle上的raw裝置原有資料資訊全部清空一次。

源資料庫SID：orcl

目標資料庫SID：orclaux

2、本次複製試驗目錄：

試驗在同平臺，同版本之間的資料快速遷移複製的另一種途徑，保證在複製後的資料庫中有源資料庫中的資料。

3、實際操作過程：

為了驗證複製的完整性，在熱備之前先建立一張驗證表：sys.test_rman裡面有一條資料。

3）、配置監聽

為了確保複製資料庫時，在資料庫沒有啟動的情況下能正常連線數目標資料庫，需要對監聽進行配置，進行靜態註冊，可以在兩端都進行配置，為了保證配置正確，推薦使用oracle net mamager進行配置。使用命令netmgr來啟動OUI。在LISTENER中配置資料庫服務，如下圖：

配置完成後，重啟監聽。

4）、並配置密碼檔案及建立相應的引數目錄

5）、建立啟動pfile檔案

SQL> create pfile='/oracle/backup/initorclaux.ora' from spfile;

File created.

SQL>

6）、修改pfile檔案

將其中的db_name 修改為：db_name='orclaux'

其他引數使用和源資料一樣的路徑和配置，因此不做修改。

7）、啟動目標資料到nomount狀態

[oracle@sigle backup]$ hostname
clone_sigle

[oracle@sigle backup]$ sq

SQL*Plus: Release 10.2.0.4.0 - Production on 星期二 3月 27 00:59:56 2012

8）、連線源資料庫及目標資料庫

在源資料庫端連線

[oracle@sigle backup]$ hostname

sigle

[oracle@sigle backup]$

[oracle@sigle ~]$ rman target /

[uniread] Loaded history (181 lines)

connected to target database: ORCL (DBID=1305151947)

RMAN> CONNECT AUXILIARY sys/sysadmin@sigleaux

connected to auxiliary database: ORCLAUX (not mounted)

RMAN>

9)、複製資料庫

需要注意的是，如果目標資料庫的資料檔案位置與源資料庫資料檔案位置相同，在執行

DUPLICATE TARGET DATABASE TO orclaux後要加nofilenamecheck引數，否則報錯：

RMAN-05001: auxiliary filename/dev/raw/raw1 conflicts with a file used by the target database

如果目標資料庫的資料檔案位置與源資料庫資料檔案位置不同，則需要加上DB_FILE_NAME_CONVERT引數來轉換資料檔案位置，例如：

DB_FILE_NAME_CONVERT=('/h1/oracle/dbs/trgt/','/h2/oracle/oradata/newdb/')

注意，在命令執行過程中，目標資料庫必須要保證沒有連線，否則指令碼執行到整個過程快結束，需要重啟目標資料庫時候掛住，直到現有連線全部退出。
