oracle--BBED (dump 深入实践三)

一,工具介绍

　　bbed是Block Browser and Editor（块浏览编辑器）的缩写，它是Oracle数据库在安装时一起附带的工具。

?????? 一般此工具倾向于仅作为Oracle内部使用，且Oracle公司并不公开此工具使用细节。

?? ? ? 由于bbed可以对Oracle数据库中的数据块进行内容修改和破坏，因此此工具功能强大同时伴有很高的使用风险。

二,工具安装

[[email?protected] BBED]$ mv ssbbded.o sbbdpt.o $ORACLE_HOME/rdbms/lib/  ---文件拷贝到oracle 库下面
[[email?protected] BBED]$ mv bbedus* $ORACLE_HOME/rdbms/mesg/            ----文件拷贝到oracle 模块下面
[[email?protected] BBED]$ make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLEME/bin/bbed  ---执行编译安装

三,配置文件

SQL> select file#||‘ ‘||name||‘ ‘||bytes from v$datafile ;

FILE#||‘‘||NAME||‘‘||BYTES
--------------------------------------------------------------------------------
1 /u01/app/oracle/oradata/oracle01/system01.dbf 849346560
2 /u01/app/oracle/oradata/oracle01/sysaux01.dbf 1121976320
3 /u01/app/oracle/oradata/oracle01/undotbs01.dbf 304087040
4 /u01/app/oracle/oradata/oracle01/users01.dbf 5242880
5 /u01/app/oracle/oradata/oracle01/example01.dbf 363069440
6 /u01/app/oracle/oradata/oracle01/test01.dbf 10485760
7 /u01/app/oracle/oradata/oracle01/test101.dbf 10485760

把输出的内容写道bbed.txt文件下面
cat bbed.txt
[[email?protected] BBED]$ cat bbed.txt
1 /u01/app/oracle/oradata/oracle01/system01.dbf 849346560
2 /u01/app/oracle/oradata/oracle01/sysaux01.dbf 1121976320
3 /u01/app/oracle/oradata/oracle01/undotbs01.dbf 304087040
4 /u01/app/oracle/oradata/oracle01/users01.dbf 5242880
5 /u01/app/oracle/oradata/oracle01/example01.dbf 363069440
6 /u01/app/oracle/oradata/oracle01/test01.dbf 10485760
7 /u01/app/oracle/oradata/oracle01/test101.dbf 10485760


bbed配置文件编写:
[[email?protected] BBED]$ cat par.bbd
blocksize=8192
listfile=bbed.txt
mode=edit
