本想练习SQL,哪知道数据库打不开了。
提示如下：
SQL> startup

Total System Global Area  612368384 bytes
Fixed Size                  1250452 bytes
Variable Size             109054828 bytes

Redo Buffers                2940928 bytes
Database mounted.

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。
