ora-01207錯誤處理
一： ora-01207錯誤解釋
[oracle@oracle ~]$ oerr ora 01207
01207, 00000, "file is more recent than control file - old control file"
// *Cause: The control file change sequence number in the data file is
// greater than the number in the control file. This implies that
// the wrong control file is being used. Note that repeatedly causing
// this error can make it stop happening without correcting the real
// problem. Every attempt to open the database will advance the
// control file change sequence number until it is great enough.
// *Action: Use the current control file or do backup control file recovery to
// make the control file current. Be sure to follow all restrictions
// on doing a backup control file recovery.
從上面的英文中不難看出，造成ora-01207錯誤的實質就是由於數據文件頭部記錄控制seq號比控制文件中記錄的該值大。
二：通過bbed修改數據文件頭部的seq號模擬該錯誤，過程如下：
說明：數據文件頭部記錄的控制文件seq號位於，如下所示
ub4 kccfhcsq @40 0x000003df 轉換爲10進製爲991
和通過表x$kcvfh查詢到的值一樣(fhcsq爲控制文件seq號）
SQL> select hxfil,fhcsq,fhscn,fhrba_seq from x$kcvfh;
HXFIL FHCSQ FHSCN FHRBA_SEQ

3 991 1077238 1
4 991 1077238 1
5 991 1077238 1
模擬過程如下：

上面模擬了數據文件頭部記錄的控制文件seq號大於控制文件記錄的seq號，下面重啓數據庫觸發報錯

三 對於ora-01207錯誤的處理
既然已經知道ora-01207的錯誤是由於數據文件頭部的記錄的控制文件seq號比控制文件的seq號大，那麼針對這個錯誤提供如下兩種處理方法
方法一：
1 利用歸檔和聯機日誌推進控制文件中的相關信息，即通過執行命令recover database using backup controlfile來實現。不過這個命令能順利執行的前提
是controlfile_change#值所在的歸檔及其之後所需歸檔能夠利用進行恢復。
2 恢復過程如下：

方法二：重建控制文件。因爲在重建控制文件的過程中，控制文件中記錄的seq號的基值會取自於數據文件頭部，從而達到一致性。其次通過重建控制文件還可以規避recover database using backup controlfile 過程中遭遇歸檔丟失問題。
