BBED是oracle內部使用的工具，9i,10g默認是自帶的，只要編譯一下就可以使用了。
下面我就來編譯一下BBED並且用它來修改下數據：
[oracle@Srv02 ~]$ cd $ORACLE_HOME/rdbms/lib [oracle@Srv02 lib]$ make -f ins_rdbms.mk $ORACLE_HOME/rdbms/lib/bbed [oracle@Srv02 lib]$ cp $ORACLE_HOME/rdbms/lib/bbed /u01/app/oracle/product/db_1/bin/
做如上操作後我們就可以直接在任何路徑下面使用BBED了。
下面我使用BBED來修改數據：
1.首先創建個表並插入兩條數據，並查看它的ROWID：
SQL> create table t1(id number,name varchar2(10)); Table created. SQL> insert into t1 values(1,'xuwu'); 1 row created. SQL> insert into t1 values(2,'xmj'); 1 row created. SQL> insert into t1 values(3,'xnk'); 1 row created. SQL> commit; Commit complete. SQL> select * from t1; ID NAME ---------- ---------- 1 xuwu 2 xmj 3 xnk SQL> select rowid,dbms_rowid.rowid_relative_fno(rowid) rel_fno,dbms_rowid.rowid_block_number(rowid) blockno, 2 dbms_rowid.rowid_row_number(rowid) rowno from t1; ROWID REL_FNO BLOCKNO ROWNO ------------------ ---------- ---------- ---------- AAAW9mAABAAAOYiAAA 1 58914 0 AAAW9mAABAAAOYiAAB 1 58914 1 AAAW9mAABAAAOYiAAC 1 58914 2 SQL>
查出listfile
SQL> select file#||' '||name||' '||bytes from v$datafile; FILE#||''||NAME||''||BYTES -------------------------------------------------------------------------------- 1 /u01/app/oracle/oradata/qxptfh01/system01.dbf 503316480 2 /u01/app/oracle/oradata/qxptfh01/undotbs01.dbf 1289748480 3 /u01/app/oracle/oradata/qxptfh01/sysaux01.dbf 429916160 4 /u01/app/oracle/oradata/qxptfh01/users01.dbf 5242880 5 /u01/app/oracle/oradata/qxptfh01/QXDATA01.dbf 524288000 6 /u01/app/oracle/oradata/qxptfh01/QXDATA02.dbf 11639193600 7 /backup/xuwu_tbs.dbf 10737418240 7 rows selected.
把上面查出來的內容放到listfile.txt文件中：
[oracle@Srv02 ~]$ cat listfile.txt 1 /u01/app/oracle/oradata/qxptfh01/system01.dbf 503316480 2 /u01/app/oracle/oradata/qxptfh01/undotbs01.dbf 1289748480 3 /u01/app/oracle/oradata/qxptfh01/sysaux01.dbf 429916160 4 /u01/app/oracle/oradata/qxptfh01/users01.dbf 5242880 5 /u01/app/oracle/oradata/qxptfh01/QXDATA01.dbf 524288000 6 /u01/app/oracle/oradata/qxptfh01/QXDATA02.dbf 11639193600 7 /backup/xuwu_tbs.dbf 10737418240 [oracle@Srv02 ~]$ pwd /home/oracle [oracle@Srv02 ~]$
現在就可以登錄BBED了：
[oracle@Srv02 ~]$ bbed password=blockedit blocksize=8192 listfile=/home/oracle/listfile.txt mode=edit BBED: Release 2.0.0.0.0 - Limited Production on Thu Nov 27 15:05:11 2014 Copyright (c) 1982, 2007, Oracle.
