由于某种原因导致该dmp异常了,而且客户的主要数据都在这个表里面,因此找我们进行恢复处理.通过工具扫描,确定dmp基本上是好的.进行二次处理,把该dmp中这个表重新恢复成dmp文件,然后导入数据库，完成恢复(包括解决某些工具有汉字乱码问题,和sqlldr换行导入问题等)

exp dmp文件损坏(坏块/corruption)恢复—跳过dmp坏块

发表于 2015 年 8 月 18 日 由 惜分飞

在有些情况下，大家都知道通过dul可以恢复损坏的dmp文件的表的数据,但是该方法有很多问题，特别是对很多数据类型的支持不够完美,比如lob,long raw类型等,而且还有可能恢复出来数据大量丢失,本人通过对dmp结构的分析,使用使用一些特殊的技巧方法,可以实现对于损坏的dmp文件,通过跳过异常坏块所在表,继续恢复后续表,从而最大程度减少损坏

Conventional export
9986063: start of table data

使用dd命令破坏T_XIFENFEI2所在位置的dmp文件

[oracle@web103 ~]$ dd if=/dev/zero of=/data/temp/t_xifenfei.dmp bs=1024 count=2 conv=notrunc seek=9747
2+0 records in
2+0 records out

尝试imp导入被破坏的dmp文件数据

[oracle@web103 ~]$ imp "'/ as sysdba'" fromuser=xifenfei touser=xifenfeinew 
>file=/data/temp/t_xifenfei.dmp log=/data/temp/imp_t_xifenfei.log

导入报IMP-00003 ORA-01740 IMP-00008,由于dmp文件被dd破坏(而且破坏位置是T_XIFENFEI2所在之处),因此imp导入到T_XIFENFEI2之时,抛出大量异常,imp终止

检查导入表情况

SQL> conn xifenfeinew/"www.xifenfei.com"
Connected.
SQL> select * from tab;

TNAME                          TABTYPE  CLUSTERID
------------------------------ ------- ----------
T_XIFENFEI1                    TABLE

SQL> select count(*) from t_xifenfei1;

  COUNT(*)
----------
     86275

和预期相符,表t_xifenfei1导入进去,但是t_xifenfei2由于坏块原因未导入,由于t_xifenfei3在t_xifenfei2之后,因此也未导入

使用CPFL程序抽取正常dmp文件

CPFL>getdmp '/data/temp/t_xifenfei.dmp' skip table 'T_XIFENFEI2'
>/data/temp/t_xifenfeinew.dmp

重新导入dmp文件

[oracle@web103 ~]$ imp "'/ as sysdba'" fromuser=xifenfei touser=xifenfeinew 
>file=/data/temp/t_xifenfeinew.dmp log=/data/temp/imp_t_xifenfeinew.log

导入了t_xifenfei1，t_xifenfei3，果然t_xifenfei2被跳过

验证导入数据

[oracle@web103 ~]$ sqlplus xifenfeinew/"www.xifenfei.com"

通过验证数据证明，通过CPFL完美跳过了坏块所在表,实现后续数据完美恢复
