1. 系統資訊

序號	角色	作業系統	版本	記憶體	磁碟	防火牆	IP地址
1	源資料庫	Windows Server	2008 R2	2G	40G	關閉	192.168.230.132
2	新資料庫	Windows Server	2008 R2	2G	40G	關閉	192.168.230.133

2. 安裝虛擬機器

參考http://blog.itpub.net/28536251/viewspace-1455381/安裝Windows系統。

3. 安裝建立資料庫

分別在2個虛擬機器上面安裝建立資料庫。

執行安裝程式。

由於只是測試，選擇基本安裝。

4. 源資料庫操作

確認資料庫執行在非歸檔模式，且沒有RMAN備份。

建立使用者，表空間及資料檔案，並建立一張表，插入2行資料。

5. 新資料庫操作

源資料庫如果出現問題，先保留現場，不去操作，將所有資料檔案，日誌檔案，控制檔案等複製到新建資料庫的對應目錄，最好是相同的目錄結構，並覆蓋原始檔。

先關閉新資料庫。

C:\Users\Administrator>sqlplus / as sysdba

複製資料後啟動資料庫。
