标题:使用bbed解决ORA-01178 file N created before last CREATE CONTROLFILE, cannot recreate

在一些情况下,因为某种原因数据库中的某个数据文件丢失,然后重建控制文件(该文件不存在,重建控制文件肯定不包含该数据文件),这个时候丢失的数据文件所有的归档都存在,尝试alter database create datafile命令创建该数据文件并且利用所有的归档来恢复该数据文件,可是因为控制文件已经重建,无法完成数据文件的重新创建(报ORA-01178错误)
出现这个错误的原因是因为数据文件的创建时间不能早于你的控制文件的创建时间,现在你重建了控制文件,那么很明显你的数据文件的创建时间要早于你的控制文件创建时间,数据库从恢复的原理上判断,你这样做法是违法,终止该操作.解决该问题的主要思路有三个:
1.修改控制文件,让数据库认为你的控制文件创建时间在该数据文件创建之前,通过该欺骗的方法来实现create datafile
2.人工创建好异常数据文件,然后让数据库开始应用归档日志,使得归档的内容能够重现到人工创建的数据文件中,从而找回归档中内容
3.使用logminer挖归档,对应成sql,然后在其他库中重现,此方法只能对于归档比较少的库
因为3比较简单,不做任何操作,因为控制文件结果不是非常了解,修改了N次还是报异常,最后放弃,使用方法2,人工重构文件完成该项工作

尝试创建数据文件,报ORA-01178

01178, 00000, "file %s created before last CREATE CONTROLFILE, cannot recreate"
// *Cause:  Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a
//          datafile that existed at the last CREATE CONTROLFILE command.
//          The information needed to recreate the file was lost with the

官方提示,因为控制文件的创建时间比你现在要创建的数据文件时间晚,所以不能完成在此数据文件基础之上完成数据文件的创建工作,如果解决该问题,使用备份的数据文件还原或者使用备份的控制文件然后创建数据文件

继续分析该数据文件

到目前,我们创建了一个和故障数据文件在同一个表空间,而且同样初始化大小的数据文件

CP新数据文件
E:\ORACLE\ORADATA\XIFENFEI\DD_1178.02.dbf 为E:\oracle\oradata\XIFENFEI\dd_ora1178.02.dbf

bbed修改相关值
因为在win中block 2其实为数据库的block 1,依次类推

m /x 01004002 block 2 offset 4
m /x 09 block 2 offset 52
m /x 5cb11c00 block 2 offset 100
m /x 09 block 2 offset 368

    不能直接编辑,需要使用其他方法拷贝出来文件编辑,或者计算在磁盘中的具体位置,然后编辑
