BBED全称oracle block brower and editor tool，可以用来更改数据block。

    在有些场合很有用，不过不被官方support。玩玩无妨:)

    安装过程如下：

    cd $ORACLE_HOME/rdbms/lib

    ls -al *bb*.o

    -rw――- 1 oracle dba 3152 Nov 7 2006 sbbdpt.o

    -rw――- 1 oracle dba 2424 Nov 7 2006 ssbbded.o

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