Oracle8i 的BBED在windows 平台下的$ORACLE_HOME/bin下可以找到
ORACLE9i数据库就自带bbed程序，就在%ORACLE_HOME%/bin目录下，在linux上面也有，需要自己编译。
9i/10g bbed：
cd $ORACLE_HOME/rdbms/lib ls -al *bb* make -f ins_rdbms.mk $ORACLE_HOME/rdbms/lib/bbed mv bbed $ORACLE_HOME/bin
11g和12.1需要10g的5个文件（bbedzhs.msb是可选的）：
/rdbms/mesg/bbed* bbedus.msb bbedus.msg bbedzhs.msb cp /tmp/lunar/ssbbded.o $ORACLE_HOME/rdbms/lib/ cp /tmp/lunar/sbbdpt.o $ORACLE_HOME/rdbms/lib/ cp /tmp/lunar/bbedus.msg $ORACLE_HOME/rdbms/mesg/ cp /tmp/lunar/bbedus.msb $ORACLE_HOME/rdbms/mesg/ cd $ORACLE_HOME/rdbms/lib ls -al *bb* make -f ins_rdbms.mk $ORACLE_HOME/rdbms/lib/bbed mv bbed $ORACLE_HOME/bin
BBED的缺省口令是 blockedit：
[oracle@lunar ~]$ bbed Password: blockedit（默认该密码） BBED: Release 2.0.0.0.0 - Limited Production on Thu Jan 17 18:32:16 2013 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. ************* !!! For Oracle Internal Use only !!! *************** BBED>
一般使用bbed，都是将一些配置信息写入到一个参数文本里，在调用bbed时，指定该参数文件。如：
先从v$datafile中获取file#,name,bytes，然后组成filelist.lst
cat /tmp/lunar/filelist.lst 1 /u01/app/oracle/oradata/dave2/system01.dbf 1761607680 cat /tmp/lunar/bbed.par blocksize=8192 listfile=/tmp/lunar/filelist.lst mode=edit password=blockedit spool=yes [oracle@lunar ~]$bbed parfile=bbed.par BBED: Release 2.0.0.0.0 - Limited Production on Thu Jan 17 18:32:16 2013 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. ************* !!! For Oracle Internal Use only !!! *************** BBED>
BBED常用命令：
set 设定当前的环境
show 查看当前的环境参数，跟sqlplus的同名命令类似。
dump 列出指定block的内容
find 在指定的block中查找指定的字符串，结果是显示出字符串，及其偏移量–offset，偏移量就是在block中的字节数
modify 修改指定block的指定偏移量的值，可以在线修改。
copy 把一个block的内容copy到另一个block中
verify 检查当前环境是否有坏块
sum 计算block的checksum，modify之后block就被标识为坏块，current checksum与reqired checksum不一致，sum命令可以计算出新的checksum并应用到当前块。
undo 回滚当前的修改操作，如果手误做错了，undo一下就ok了，回到原来的状态。
revert 回滚所有之前的修改操作，意思就是 undo all
可以使用help来查看bbed的命令语法：
