Oracle BBED 工具介绍 收藏
BBED(Oracle Block Brower and 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。
一．BBED 的安装
BBED在windows 8i中在$ORACLE_HOME/bin下可以找到，9i中似乎未随软件发布，故
在windows没有这个工具，
在linux上面有，需要编译。
在9i/10g中连接生成bbed:
cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk $ORACLE_HOME/rdbms/lib/bbed
以上生成的bbed可执行文件在$ORACLE_HOME/rdbms/lib目录，可以复制到其他位置或者其他同Oracle版本的机器上运行。也可通过以下命令将bbed生成到$ORACLE_HOME/bin目录
make -f ins_rdbms.mk BBED=$ORACLE_HOME/bin/bbed $ORACLE_HOME/bin/bbed
在11g中生成bbed，需要先从10g中复制如下文件到相应目录，然后再执行上述连接命令:
$ORACLE_HOME/rdbms/lib/ssbbded.o
$ORACLE_HOME/rdbms/lib/sbbdpt.o
$ORACLE_HOME/rdbms/mesg/bbedus.msb
BBED设置了口令保护，密码为blockedit。
BBED的命令行参数：
$bbed help=yes
PASSWORD - Required parameter
FILENAME - Database file name
BLOCKSIZE - Database block size
LISTFILE - List file name
MODE - [browse/edit]
SPOOL - Spool to logfile [no/yes]
CMDFILE - BBED command file name
LOGFILE - BBED log file name
PARFILE - Parameter file name
BIFILE - BBED before-image file name
REVERT - Rollback changes from BIFILE [no/yes]
SILENT - Hide banner [no/yes]
HELP - Show all valid parameters [no/yes]
一般将一些常用选项写入到一个parfile中，比如
bbed.par 文件内容：
blocksize=8192
listfile=filelist.txt
mode=edit
其中filelist.txt列出了需要使用BBED编辑的数据文件列表，格式为：文件编号 文件名字 文件大小， 可通过该语句查询
SQL> select file#, name, bytes from v$datafile;
FILE# NAME BYTES
---------- ------------------------------------------------ ----------
1 /export/home/oradata/orcl/system01.dbf 450887680
2 /export/home/oradata/orcl/undotbs01.dbf 209715200
3 /export/home/oradata/orcl/sysaux01.dbf 188743680
4 /export/home/oradata/orcl/users01.dbf 5242880
将查询结果作为filelist.txt的内容即可。这里的文件编号不一定要和数据库里的file_id相同，当然最好能设置相同，以免在处理过程中搞混淆了。
编好了就可以运行bbed了
[oracle@vm1 oracle]$ bbed parfile=bbed.par

下面是几个常用的：
set 设定当前的环境。
show 查看当前的环境参数，跟sqlplus的同名命令类似。
dump 列出指定block的内容
find 在指定的block中查找指定的字符串，结果是显示出字符串，及其偏移量--offset，偏移量就是在block中的字节数
modify 修改指定block的指定偏移量的值，可以在线修改。
copy 把一个block的内容copy到另一个block中
verify 检查当前环境是否有坏块
sum 计算block的checksum，modify之后block就被标识为坏块，current checksum与reqired checksum不一致，sum命令可以计算出新的checksum并应用到当前块。
undo 回滚当前的修改操作，如果手误做错了，undo一下就ok了，回到原来的状态。
revert 回滚所有之前的修改操作，意思就是 undo all
二. 实验测试
先建个表，插入1条数据。
SQL> create table dave(name varchar(20)) tablespace users;
Table created.
SQL> insert into dave values(‘dmm’);
1 row created.
SQL> commit;
Commit complete.
SQL>select segment_name,file_id,block_id,blocks from dba_extents
where segment_name='DAVE'; -- 名称要大写，不然查不到结果
SEGMENT_NA FILE_ID BLOCK_ID BLOCKS
---------- ---------- ---------- ----------
DAVE 4 17 8
表存放在file 4 block 17: 17+8 上面.
先关闭数据库，对users数据文件作个cp。
SQL> shutdown immediate
[oracle@vm1 test]$ cp users01.dbf users01.dbf.bak
SQL> startup
重新启动完数据库，进入bbed
$ ./bbed parfile=bbed.par

offset 偏移量 从 0 到 511 单位是字节，数据块是8k的，想看完全就要扩大offset的范围

Offsets: 0 to 8191 1024 * 8 = 8192个字节,正好8K。在这段数字中，有一个就是我们插入的数字. 可以通过一下方式查看。
SQL> select * from dave;
NAME
--------------------
Dmm
SQL> select dump('d',1016) from dual;
DUMP('D',1016)
--------------------------------------
Typ=96 Len=1 CharacterSet=AL32UTF8: 64
SQL> select dump('m',1016) from dual;
DUMP('M',1016)
--------------------------------------
Typ=96 Len=1 CharacterSet=AL32UTF8: 6d
SQL> select dump(‘dmm’,1016) from dual;
DUMP('DUMP',1016)
-----------------------------------------------
Typ=96 Len=4 CharacterSet=AL32UTF8: 64,75,6d,70
字符串’DMM’对应的16进制编码是64,75,6d,70。如果数据量大的话，可以用find命令查找
BBED> help find
FIND[/x|d|u|o|c] numeric/character string [ TOP | CURR ]
BBED> set file 4
FILE# 4
BBED> set block 17

000220ed 35
在find之前先设置想要查找的 file 和 block，默认是十进制的ascii编码，/x 表示16进制，find的结果显示出offset，即字符出现的位置。
我们将刚才查出来的偏移量进行修改：
BBED> help modify

undo就相当于sqlplus里面的 rollback 不过是回滚上一步，而不是所有操作。
下面试试revert，不过要重新登陆，因为revert是回滚这次登陆以来所有的操作。

个人感觉bbed主要用在数据库恢复的时候，比如由于误操作把数据库的字典表的信息改错了，导致数据库不能启动了，此时用bbed在脱机的情况下把字典表的值再改回来。使数据库open。
用modify改完数据之后，block处于corrupt状态，所以要通过sum命令计算并应用checksum值，使block状态恢复正常。

修改完之后block的状态是corrupt的。用sum命令使之有效。
BBED> help sum
SUM [ DBA | FILE | FILENAME | BLOCK ] [ APPLY ]
BBED> sum file 4 block 17
Check value for File 4, Block 17:
current = 0xa711, required = 0xc573
此时 current checksum 是0xa711，required checksum 是0xc573
BBED> sum file 4 block 17 apply
Check value for File 4, Block 17:
current = 0xc573, required = 0xc573
加上apply参数，使checksum一致。此时block状态恢复正常。
