bbed破坏数据文件
一、安装bbed
[oracle@ECP-UC-DB1 bin]$ cd $ORACLE_HOME/rdbms/lib
[oracle@ECP-UC-DB1 lib]$ ls -al *bb*
-rw-r–r– 1 oracle oinstall 1863 Mar 11 2008 sbbdpt.o
-rw-r–r– 1 oracle oinstall 1191 Mar 11 2008 ssbbded.o
[oracle@ECP-UC-DB1 lib]$ make -f ins_rdbms.mk $ORACLE_HOME/rdbms/lib/bbed
[oracle@ECP-UC-DB1 lib]$ mv bbed $ORACLE_HOME/bin
[oracle@ECP-UC-DB1 lib]$ cd ~
二、bben入门

三、创建测试表
[oracle@ECP-UC-DB1 ~]$ sqlplus chf/xifenfei

四、bben准备工作
1、创建参数文件
[oracle@ECP-UC-DB1 ~]$ cat parfile.conf
blocksize=8192
listfile=list
mode=edit
2、创建数据文件列表
[oracle@ECP-UC-DB1 ~]$ cat list
1 /opt/oracle/oradata/test/xifenfei01.dbf 2097160192
五、修改数据块中内容
[oracle@ECP-UC-DB1 ~]$ bbed parfile=parfile.conf

************* !!! For Oracle Internal Use only !!! ***************
1、定位需要修改块
BBED> set dba 1,780
DBA 0x0040030c (4195084 1,780)
2、查看相关内容
BBED> find /c xifenfei
File: /opt/oracle/oradata/test/xifenfei01.dbf (1)
Block: 780 Offsets: 8180 to 8191 Dba:0x0040030c
————————————————————————
78696665 6e666569 01062bce
<32 bytes per line>
3、dump文件中内容
BBED> dump /v dba 1,780 offset 8180 count 32
File: /opt/oracle/oradata/test/xifenfei01.dbf (1)
Block: 780 Offsets: 8170 to 8191 Dba:0x0040030c

65690106 2bce l ei..+.
<16 bytes per line>
4、修改数据块内容
BBED> modify 500 dba 1,780
Warning: contents of previous BIFILE will be lost. Proceed? (Y/N) y
File: /opt/oracle/oradata/test/xifenfei01.dbf (1)
Block: 780 Offsets: 8180 to 8191 Dba:0x0040030c
————————————————————————

<32 bytes per line>
BBED> find /c xienfei
BBED-00212: search string not found
BBED> exit
六、验证修改是否成功
1、dbv验证
[oracle@ECP-UC-DB1 ~]$ dbv file =/opt/oracle/oradata/test/xifenfei01.dbf
