ora-01207错误处理一: ora-01207错误解释

[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.
从上面的英文中不难看出,造成ora-01207错误的实质就是由于数据文件头部记录控制seq号比控制文件中记录的该值大。

二:通过bbed修改数据文件头部的seq号模拟该错误,过程如下:

说明:数据文件头部记录的控制文件seq号位于,如下所示
ub4 kccfhcsq @40 0x000003df 转换为10进制为991
和通过表x$kcvfh查询到的值一样(fhcsq为控制文件seq号)

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
模拟过程如下:

上面模拟了数据文件头部记录的控制文件seq号大于控制文件记录的seq号,下面重启数据库触发报错

三 对于ora-01207错误的处理
既然已经知道ora-01207的错误是由于数据文件头部的记录的控制文件seq号比控制文件的seq号大,那么针对这个错误提供如下两种处理方法
方法一:
1 利用归档和联机日志推进控制文件中的相关信息,即通过执行命令recover database using backup controlfile来实现。不过这个命令能顺利执行的前提
是controlfile_change#值所在的归档及其之后所需归档能够利用进行恢复。
2 恢复过程如下:

5 1102 1086663 1

方法二:重建控制文件。因为在重建控制文件的过程中,控制文件中记录的seq号的基值会取自于数据文件头部,从而达到一致性。其次通过重建控制文件还可以规避recover database using backup controlfile 过程中遭遇归档丢失问题。
