oracle bbed安装

Oracle BBED（Oracle Block Browser and Editor）工具是Oracle内部提供的数据块级别查看和修改工具。借助这个工具，我们可以方便的查看到Oracle块block级别的存储细节信息，更好的了解Oracle Internal结构技术细节

首先，要说明BBED是非Oracle推荐使用的工具，只提供给内部进行恢复处理使用，对外是不提供任何资料和相关技术支持。所以，我们如果计划使用该工具，特别是在生产环境下使用，都是我们的最后选择方案。一定要在有备份能恢复的时候进行使用，否则贸然使用BBED，容易造成数据库启动失败或者更严重的问题。

　　BBED提供的版本中，只有Linux/Unix，在Windows上是没有对应版本的。索引使用BBED的环境通常是命令行方式。而且BBED在Oracle内部是没有提供编译好的现成版本，需要我们手工性编译链接操作。

oracle 11g下的安装

BBED is not available in 11g but you can still link it after getting the following files

from any previous version like 10gR2.

Copy $ORA10g_HOME/rdbms/lib/ssbbded.o to $ORA11g_HOME/rdbms/lib
Copy $ORA10g_HOME/rdbms/lib/sbbdpt.o to $ORA11g_HOME/rdbms/lib

Message files (list may differ):
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

Issue the following command:
make -f $ORA11g_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed

$ORACLE_HOME/bin/bbed

$ORA11g_HOME/bin/bbed
