BBED介紹：
BBED(Oracle Block Browerand EDitor Tool)，用來(lái)直接查看和修改數(shù)據(jù)文件數(shù)據(jù)的一個(gè)工具，是Oracle一款內(nèi)部工具，可以直接修改Oracle數(shù)據(jù)文件塊的內(nèi)容，在一些極端恢復(fù)場(chǎng)景下比較有用。該工具不受Oracle支持，所以默認(rèn)是沒(méi)有生成可執(zhí)行文件的，在使用前需要重新連接。
本文詳細(xì)介紹了關(guān)于Oracle 11g下編譯使用BBED的方法教程，下面話(huà)不多說(shuō)，來(lái)一起看看詳細(xì)的介紹：
環(huán)境：RHEL 6.4 + Oracle 11.2.0.4
1. 拷貝缺失文件
11g中缺失幾個(gè)相關(guān)文件，但我們實(shí)際可以從10g拷貝相關(guān)文件到11g對(duì)應(yīng)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 $ORACLE_HOME/bin/bbed
成功編譯的結(jié)果如下：
[oracle@JY-DB01 dbhome_1]$ 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

另外，一般使用bbed都是在參數(shù)配置文件中寫(xiě)好配置參數(shù)，然后直接調(diào)用配置文件，比如：
--編輯/tmp/bbed.par參數(shù)配置文件 blocksize=8192 listfile=/tmp/listfile.txt mode=edit --編輯/tmp/listfile.txt文件 5 /u02/oradata/jingyu/dbs_d_jingyu01.dbf 31457280 6 /u02/oradata/jingyu/dbs_i_jingyu01.dbf 31457280 --調(diào)用bbed cd /tmp bbed parfile=bbed.par
