本想练习SQL,哪知道数据库打不开了。
提示如下:
SQL> startup
ORACLE instance started.
Total System Global Area 612368384 bytes
Fixed Size 1250452 bytes
Variable Size 109054828 bytes
Database Buffers 499122176 bytes
Redo Buffers 2940928 bytes
Database mounted.
ORA-01122: database file 6 failed verification check
ORA-01110: data file 6: 'D:\ORADATA\DATA02.DBF'
ORA-01207: file is more recent than control file - old control file
参考 http://space.itpub.net/67668/viewspace-353270
作如下操作,终于恢复正常。

4、打开f:\aa ,选择下面文件保存为f:\create controlfiel.txt,
