4.修改旧数据文件头中控制文件备份的计数器（kcvfhccc）的值

5.重新生成sum

BBED> sum apply

Check value for File 1, Block 1:

current = 0xec9b, required = 0xec9b

6.查询各个数据文件头scn

SQL> select file#,checkpoint_change#,name from v$datafile_header;

     FILE# CHECKPOINT_CHANGE# NAME

SQL> alter database open;

Database altered.

至此数据库成功启动咯~
