Oracle 11g下编译使用BBED的方法教程

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.msg

2. 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/lib

3. 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

--3.2 bbed命令参数
[oracle@JY-DB01 tmp]$ bbed help=y
PASSWORD - Required parameter
FILENAME - Database file name
BLOCKSIZE - Database block size
LISTFILE - List file name
MODE - [browse/edit]
SPOOL - Spool to logfile [no/yes]
CMDFILE - BBED command file name
LOGFILE - BBED log file name
PARFILE - Parameter file name
BIFILE - BBED before-image file name
REVERT - Rollback changes from BIFILE [no/yes]
SILENT - Hide banner [no/yes]
HELP - Show all valid parameters [no/yes]

另外，一般使用bbed都是在参数配置文件中写好配置参数，然后直接调用配置文件，比如：

--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 
5 /u02/oradata/jingyu/dbs_d_jingyu01.dbf 31457280
6 /u02/oradata/jingyu/dbs_i_jingyu01.dbf 31457280
--调用bbed
cd /tmp
bbed parfile=bbed.par
