以下的相關內容主要介紹的是，解決由於一次誤操作而引起的Oracle數據庫大恢復的另外一種語法即，重建控制文件（重建控制文件之前，備份controlfile和online redolog）的實際操作方案。

- LOGFILE GROUP 1 ('/ora10g/app/oradata/ldbra/redo01.log')
SIZE 51200K,- GROUP 2 ('/ora10g/app/oradata/ldbra/redo02.log')
SIZE 51200K,- GROUP 3 ('/ora10g/app/oradata/ldbra/redo03.log')
SIZE 51200K RESETLOGS;
用上述相關語句來解決由於一次誤操作而引起的Oracle數據庫大恢復的操作似乎重建成功了！但是進行recover的時候報錯了！

- ORA-00283: recovery session canceled due to errors
- ORA-00600: internal error code, arguments: [kcvhvdf_1],

可以看到控制文件在重建的過程中進行了dbid重置
引用
- SQL> select dbid from v$database;
- DBID
- 1498845164
問題到這裡似乎失去了頭緒，呵呵，拷回之前備份的控制文件替換剛建的控制文件。因為我采用的是resetlog選項創建控制文件，從理論上來講，應該是會重置redolog的，即重新創建redolog。但是目前采用此選項確報ORA-01227錯誤。不可思議！後來一想可能是跟數據文件中的dbid為0有關。於是采用終極修復方法，bbed！首先將所有數據文件的dbid用bbed工具重置為1488207495，其次將fuzzy標記打為0x2000（因為數據庫被ckpt進程異常終止，將標記打為0x2000表示數據庫是shutdown immediate關閉），采用上述方法之後控制文件成功創建！

嘗試打Oracle開數據庫
- SQL> alter database open RESETLOGS;
出現數據庫掛起狀態，後台alert日志顯示[2662]錯誤，呵呵，看到這個錯誤，希望就來了！
