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)

解决imp导入数据报IMP-00098错误

Posted on by

晚上十点多，准备睡觉了，一个朋友在qq上找到我,说他们数据库imp异常,希望我帮忙看看
大概情况
使用exp/imp升级并迁移数据库从win 10.2.0.1 升级到linux 11.2.0.3 由于硬盘空间不够，使用exp把win上面数据导出来，格式化掉win的数据文件所在硬盘格式化并加入到linux系统中(也就是说，故障之时，只有dmp文件，没有了数据文件）,因为原库没有了,dmp又报错,所以担心了起来.

这里可以知道数据库exp的客户端是版本是10.2.0.1,使用编码是US7ASCII,但是导入的库编码是ZHS16GBK

这里我们可以知道数据库编码是ZHS16GBK,exp客户端编码为US7ASCII,因此到导出过程中发生了一次由ZHS16GBK到US7ASCII的编码转换

检查新库发现,其db编码为ZHS16GBK,新库的NLS设置为:nls_lang=AMERICAN_AMERICA.ZHS16GBK
整个导出流程是:db编码为ZHS16GBK的数据库被客户端编码为US7ASCII的exp导出,然后被编码为ZHS16GBK的imp导入到db编码为ZHS16GBK的数据库中

故障可能性定位
1.可能在从ZHS16GBK到US7ASCII的编码转换中发生数据异常,也就是说dmp文件本身异常(我们最不希望出现的结果)
2.由于数据库导出过场会发生编码转换(ZHS16GBK->US7ASCII),而导入过程未发生编码转换(ZHS16GBK->ZHS16GBK),从而出现异常

分析并解决
1. 使用dul扫描dmp文件发现汉字都能够识别,而且exp成功的记录条数在dul扫描中都完全正常恢复出来,证明dmp文件是正常的
2. 基于dmp文件正常,编码转换的过程,得出结论在该库的imp过程中设置nls_lang=AMERICAN_AMERICA.US7ASCII问题应该就可以正常解决.果不其然,设置了NLS_LANG之后imp导入数据OK

得出结论
1. 做升级,迁移尽快保留多一份数据,这次吓得不轻
2. exp/imp最好前后客户端编码一致,否则可能被转换晕
