oracle dmp被加密恢复

发表于 2019 年 11 月 24 日 由 惜分飞

接到朋友恢复请求,oracle dmp文件被加密
20191124230422

通过分析文件发现该加密主要是对头尾部分block按照每16byte中8个byte置空和部分加密
20191124230702
20191124231600

通过进行恢复,对损坏部分进行跳过,剩余数据直接导入数据库,通过show=y测试数据可以正常入库,实现了dmp文件表数据的完美恢复

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

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> select * from tab;

SQL> select count(*) from t_xifenfei1;

  COUNT(*)

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
