本文链接地址: 如何在windows下运用dd来下修复坏块?

前不久恢复了一个10201 for windows的库,由于坏块导致数据库异常。
我们知道,对于windows来说,相比unix或linux 操作起来更麻烦,其实windows也是可以使用dd的,
运用dd和UE基本上可以起到和使用bbed一样的效果。大家可以在这里下载dd for win版本dd-0.6beta3



由于我这里是10204的,所以就不用9iR2的bbed for win版本了,我将dd出来的file 5.13.dd文件传到linux中,进行修复

然后oracle在做扫描block的时候,会跳过该坏块,类似event 10231.

可以发现,完全跳过了坏块file 5 block 13,现在正常数据是300条(其中坏块13中包含数据199条).



最后再补充一点的是,如果表有索引,那么记得操作完以后记得rebuild index。

    I’m sorry to annoy you like this but I just discovered your website and have to admit it’s outstanding. The one thing that I think would help you however is the SEOpressor wordpress plugin. It is frankly the greatest SEO plugin for wordpress blogs that exists today. In exactly Five days my site went from obscurity to the very first page of google after utilizing the SEOpressor plugin. If you’re serious about SEO you can get it here
