BBED介紹：
BBED(Oracle Block Browerand EDitor Tool)，用來直接查看和修改數據文件數據的一個工具，是Oracle一款內部工具，可以直接修改Oracle數據文件塊的內容，在一些極端恢復場景下比較有用。該工具不受Oracle支持，所以默認是沒有生成可執行文件的，在使用前需要重新連接。
本文詳細介紹了關于Oracle 11g下編譯使用BBED的方法教程，下面話不多說，來一起看看詳細的介紹：
環境：RHEL 6.4 + Oracle 11.2.0.4
1. 拷貝缺失文件
11g中缺失幾個相關文件，但我們實際可以從10g拷貝相關文件到11g對應目錄下：
$ORACLE_HOME/rdbms/lib/sbbdpt.o$ORACLE_HOME/rdbms/lib/ssbbded.o$ORACLE_HOME/rdbms/mesg/bbedus.msb$ORACLE_HOME/rdbms/mesg/bbedus.msg
2. 編譯BBED
make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed $ORACLE_HOME/bin/bbed
成功編譯的結果如下：
[oracle@JY-DB01 dbhome_1]$ make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed $ORACLE_HOME/bin/bbedLinking BBED utility (bbed)rm -f /u02/app/oracle/product/11.2.0/dbhome_1/bin/bbedgcc -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

另外，一般使用bbed都是在參數配置文件中寫好配置參數，然后直接調用配置文件，比如：
--編輯/tmp/bbed.par參數配置文件blocksize=8192listfile=/tmp/listfile.txtmode=edit--編輯/tmp/listfile.txt文件 5 /u02/oradata/jingyu/dbs_d_jingyu01.dbf 314572806 /u02/oradata/jingyu/dbs_i_jingyu01.dbf 31457280--調用bbedcd /tmpbbed parfile=bbed.par
