BBED使用

BBED是oracle内部使用的工具,9i,10g默认是自带的,只要编译一下就可以使用了。

创新互联坚持“要么做到,要么别承诺”的工作理念,服务领域包括:成都网站建设、成都网站制作、企业官网、英文网站、手机端网站、网站推广等服务,满足客户于互联网时代的新会网站设计、移动媒体设计的需求,帮助企业找到有效的互联网解决方案。努力成为您成熟可靠的网络建设合作伙伴!

下面我就来编译一下BBED并且用它来修改下数据:

[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/

 

做如上操作后我们就可以直接在任何路径下面使用BBED了。

下面我使用BBED来修改数据:

1.首先创建个表并插入两条数据,并查看它的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

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.

把上面查出来的内容放到listfile.txt文件中:

[oracle@Srv02 ~]$ cat listfile.txt1 /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 ~]$

现在就可以登录BBED了:

[oracle@Srv02 ~]$ bbed password=blockedit blocksize=8192 listfile=/home/oracle/listfile.txt mode=edit
