今天是2014-04-03。隨記一下今天遇到的一個問題吧。
環境介紹：
gi version：11.2.0.4.0
database version：11.2.0.4.0
oracle linux：Linux Server release 6.4
RAC雙節點ASM+restart-alone ASM
問題描述：
在duplicate 數據庫後再啟動standby 數據庫的實時應用時出現在RAC1可以正常連接 standby,但RAC2無法連接，如下錯誤：

問題排查：
檢查remote_loging_passwordfile參數設置皆為EXCLUSIVE。其他參數沒有任何可疑問題。
問題解決：
既然日志中提示認證出現問題，且只有一個節點可以連接到standby database，那麼將該節點的密碼文件傳到節點RAC2。最終問題得到解決：
