一、BBED工具安装 for 10g/9i
######################################################
1、BBED工具介绍

全称:Block Browser/Editor
通过BBED工具，用户可以直接打开数据文件，修改其中的内容。
BBED工具位于$ORACLE_HOME/bin目录。

Oracle8i 的BBED在windows 平台下的$ORACLE_HOME/bin下可以找到，9i中似乎未随软件发布，故在windows没有这个工具，
在linux上面有，需要编译。
我的是linux，有这个工具，需编译如下：
[oracle@source bin]$ cd /oracle/product/10.2.0/db_1/rdbms/lib
[oracle@source lib]$ make -f ins_rdbms.mk /oracle/product/10.2.0/db_1/rdbms/lib/bbed

还真不少，下面是几个常用的：

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

二、BBED工具安装 for 11g
###############################################################

OracleDatabase 11g中缺省的未提供BBED库文件，但是可以用10g的文件编译出来，需要先从10g中复制如下文件到相应目录，然后再执行上述连接命令，参考如下步骤：

1、复制Oracle 10g文件

Copy $ORA10g_HOME/rdbms/lib/ssbbded.o to $ORA11g_HOME/rdbms/lib
Copy $ORA10g_HOME/rdbms/lib/sbbdpt.o to $ORA11g_HOME/rdbms/lib
Copy $ORA10g_HOME/rdbms/mesg/bbedus.msb to $ORA11g_HOME/rdbms/mesg
Copy $ORA10g_HOME/rdbms/mesg/bbedus.msg to $ORA11g_HOME/rdbms/mesg
Copy $ORA10g_HOME/rdbms/mesg/bbedar.msb to $ORA11g_HOME/rdbms/mesg

2、编译

make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed $ORACLE_HOME/bin/bbed

[oracle@zll:/oracle/app/oracle/product/11.2.0/rdbms]$make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed $ORACLE_HOME/bin/bbed
