kdbchk: the amount of space used is not equal to block size
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=8192 DBVERIFY: Release 10.2.0.1.0 - Production on Fri Jan 16 23:05:01 2015 Copyright (c) 1982, 2005, Oracle. All rights reserved. DBVERIFY - Verification starting : FILE = /u01/app/oracle/oradata/ORCL/datafile/test_01.dbf

[oracle@ora10 controlfile]$
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
