Oracle关系数据库管理系统
Oracle Database，又名Oracle RDBMS，或简称Oracle。是甲骨文公司的一款关系数据库管理系统。到目前仍在数据库市场上占有主要份额。
BBED介绍：
BBED(Oracle Block Browerand EDitor Tool)，用来直接查看和修改数据文件数据的一个工具，是Oracle一款内部工具，可以直接修改Oracle数据文件块的内容，在一些极端恢复场景下比较有用。该工具不受Oracle支持，所以默认是没有生成可执行文件的，在使用前需要重新连接。
本文详细介绍了关于Oracle 11g下编译使用BBED的方法教程，下面话不多说，来一起看看详细的介绍：
环境：RHEL 6.4 + Oracle 11.2.0.4
1. 拷贝缺失文件
11g中缺失几个相关文件，但我们实际可以从10g拷贝相关文件到11g对应目录下：
$ORACLE_HOME/rdbms/lib/sbbdpt.o
$ORACLE_HOME/rdbms/lib/ssbbded.o
$ORACLE_HOME/rdbms/mesg/bbedus.msb
$ORACLE_HOME/rdbms/mesg/bbedus.msg2. 编译BBED
make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed $ORACLE_HOME/bin/bbed成功编译的结果如下：
[oracle@JY-DB01 dbhome_1]$ make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed $ORACLE_HOME/bin/bbed
Linking BBED utility (bbed)
rm -f /u02/app/oracle/product/11.2.0/dbhome_1/bin/bbed
gcc -o /u02/app/oracle/product/11.2.0/dbhome_1/bin/bbed -m64 -z noexecstack -L/u02/app/oracle/product/11.2.0/dbhome_1/rdbms/lib/ -L/u02/app/oracle/product/11.2.0/dbhome_1/lib/ -L/u02/app/oracle/product/11.2.0/dbhome_1/lib/stubs/ /u02/app/oracle/product/11.2.0/dbhome_1/lib/s0main.o /u02/app/oracle/product/11.2.0/dbhome_1/rdbms/lib/ssbbded.o /u02/app/oracle/product/11.2.0/dbhome_1/rdbms/lib/sbbdpt.o `cat /u02/app/oracle/product/11.2.0/dbhome_1/lib/ldflags` -lncrypt11 -lnsgr11 -lnzjs11 -ln11 -lnl11 -ldbtools11 -lclntsh `cat /u02/app/oracle/product/11.2.0/dbhome_1/lib/ldflags` -lncrypt11 -lnsgr11 -lnzjs11 -ln11 -lnl11 -lnro11 `cat /u02/app/oracle/product/11.2.0/dbhome_1/lib/ldflags` -lncrypt11 -lnsgr11 -lnzjs11 -ln11 -lnl11 -lnnz11 -lzt11 -lztkg11 -lclient11 -lnnetd11 -lvsn11 -lcommon11 -lgeneric11 -lmm -lsnls11 -lnls11 -lcore11 -lsnls11 -lnls11 -lcore11 -lsnls11 -lnls11 -lxml11 -lcore11 -lunls11 -lsnls11 -lnls11 -lcore11 -lnls11 `cat /u02/app/oracle/product/11.2.0/dbhome_1/lib/ldflags` -lncrypt11 -lnsgr11 -lnzjs11 -ln11 -lnl11 -lnro11 `cat /u02/app/oracle/product/11.2.0/dbhome_1/lib/ldflags` -lncrypt11 -lnsgr11 -lnzjs11 -ln11 -lnl11 -lclient11 -lnnetd11 -lvsn11 -lcommon11 -lgeneric11 -lsnls11 -lnls11 -lcore11 -lsnls11 -lnls11 -lcore11 -lsnls11 -lnls11 -lxml11 -lcore11 -lunls11 -lsnls11 -lnls11 -lcore11 -lnls11 -lclient11 -lnnetd11 -lvsn11 -lcommon11 -lgeneric11 -lsnls11 -lnls11 -lcore11 -lsnls11 -lnls11 -lcore11 -lsnls11 -lnls11 -lxml11 -lcore11 -lunls11 -lsnls11 -lnls11 -lcore11 -lnls11 `cat /u02/app/oracle/product/11.2.0/dbhome_1/lib/sysliblist` -Wl,-rpath,/u02/app/oracle/product/11.2.0/dbhome_1/lib -lm `cat /u02/app/oracle/product/11.2.0/dbhome_1/lib/sysliblist` -ldl -lm -L/u02/app/oracle/product/11.2.0/dbhome_1/lib3. BBED使用测试
--3.1 bbed命令测试可用
[oracle@JY-DB01 dbhome_1]$ bbed
Password: --密码默认是blockedit

--编辑/tmp/bbed.par参数配置文件
blocksize=8192
listfile=/tmp/listfile.txt
mode=edit
--编辑/tmp/listfile.txt文件
