一.对数据文件检查

注意:应该在关闭数据库模式下进行bbed的操作

[oracle@ora10 controlfile]$  dbv file=/u01/app/oracle/oradata/ORCL/datafile/test_01.dbf blocksize=8192DBVERIFY: Release 10.2.0.1.0 - Production on Fri Jan 16 23:05:01 2015Copyright (c) 1982, 2005, Oracle.

文件test_01.dbf的3252块 出现问题

二.查找资料

  dbsnake的建议,将所有itl的fsc全部改为0,然后将kdbh.kdbhavsp和kdbh.kdbhtosp的值改成相等。它们的值都等于dbv校验中显示的dtl-used=8088-3681=4407。

三.利用bbed修复
