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)

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:

BBED> help all
SET DBA [ dba | file#, block# ]
SET FILENAME 'filename'
SET FILE file#
SET BLOCK [+/-]block#
SET OFFSET [ [+/-]byte offset | symbol | *symbol ]
SET BLOCKSIZE bytes
SET LIST[FILE] 'filename'
SET WIDTH character_count
SET COUNT bytes_to_display
SET IBASE [ HEX | OCT | DEC ]
SET OBASE [ HEX | OCT | DEC ]
SET MODE  [ BROWSE | EDIT ]

</Nuf>:
N - a number which specifies a repeat count.
u - a letter which specifies a unit size:
  b - b1, ub1 (byte)
  h - b2, ub2 (half-word)
  w - b4, ub4(word)
  r - Oracle table/index row
f - a letter which specifies a display format:
  x - hexadecimal
  d - decimal
  u - unsigned decimal
  o - octal
  c - character (native)
  n - Oracle number
  t - Oracle date
  i - Oracle rowid
