oracle刪除使用者後的恢復測試

goodlatch發表於2015-03-17
Oracle
用到2個機子
主節點 192.168.119.145 hostname=psd
輔助節點192.168.119.146 hostname=test
要求有rman備份

方法一：如果庫上只有這一個業務使用者，就可以直接用rman 做全庫的時間點恢復。
方法二：如果有多個使用者，大致思路，在psd節點上備份資料庫，然後刪除使用者，之後將備份恢復到test節點上，然後將test節點的使用者資料邏輯匯出，最後匯入到psd節點。

方法二的測試

確認資料庫是歸檔模式，首先在scott使用者下建立一個t1表，並插入資料

接下來開始備份資料庫，備份完在向t1表插入資料，然後建立t2表，之後刪掉scott使用者

把剛剛的rman備份、pfile檔案以及密碼檔案複製到192.168.119.146上，然後我們就要確定drop scott的具體時間，用logminer來搞定

從這裡我們可以判斷，drop使用者的時間是 2015-03-17 11:46:13，我的測試機器上沒有多少歸檔，但是在生產環境歸檔會很多，想確定drop的時間就得多看幾個歸檔日誌了。
確定時間，我們就開始在輔助節點做恢復操作

發現scott回收站裡有很多垃圾表，可以無視，我們發現t1,t2的資料都正常，這時候只要把scott的資料匯出來再匯入到主庫就好了
