使用者管理的熱備份方式複製資料庫

1. 建立例項, 密碼檔案, 初始化引數檔案, 以及目標庫相應目錄
> oradim -new -sid dup （Windows下需要）
> orapwd file=pwddup password=xxxxxx（Windows下需要）
> mkdir %ORACLE_BASE%\admin\dup
> mkdir %ORACLE_BASE%\admin\dup\adump
> mkdir %ORACLE_BASE%\admin\dup\bdump
> mkdir %ORACLE_BASE%\admin\dup\cdump
> mkdir %ORACLE_BASE%\admin\dup\udump

2. 在源庫開始熱備份, 並複製資料檔案到目標庫目錄
GO> alter database begin backup;

3. 源庫停止熱備份
GO> alter database end backup;

4. 歸檔源庫當前日誌, 並複製到目標庫歸檔目錄
GO> select * from v$log;
    GROUP# SEQUENCE# ARC STATUS  
---------- --------- --- --------
         1        10 YES ACTIVE  
         2        11 NO  CURRENT 
         3         9 YES INACTIVE

GO> alter system archive log current;


5. 將目標庫啟動到 nomount 狀態, 並建立控制檔案
DUP> startup nomount

6. 對目標庫做介質恢復
DUP> recover database using backup controlfile until cancel;

7. 以 resetlogs 方式開啟目標庫
DUP> alter database open resetlogs;

8. 新增臨時檔案到目標庫
DUP> alter tablespace temp add tempfile 'D:\Data\oracle10gr2\dup\temp01.dbf' size 5m reuse;
DUP> select file#,name from v$tempfile;
     FILE# NAME
---------- ----------------------------------------
         1 D:\DATA\ORACLE10GR2\DUP\TEMP01.DBF



9. 修改目標庫DBID
DUP> select dbid,name from v$database;
      DBID NAME
---------- ----------------------------------------
1002322791 DUP

DUP> shutdown immediate
DUP> startup mount

> nid target=sys/oracle
