数据文件users034.dbf users012.dbf能cp出去。
请看下,谢谢!
非归档 没有备份。
尽力能完成啥样算啥样了 上次的200多g备份删掉了。

我把这2个数据文件drop掉,数据库会起来吗?
数据丢失是一定的了,不知道影响会多大,接触数据库时间很长,但是dba的活很少干。
多谢!
offline drop 后,如果数据库能启来还好,如果启不来的话这个drop掉的数据文件是否再不能用了?
多谢各位,最后确诊下,放假回来就动手了。
谢谢lemonlili ,小虫说是硬件有问题,我也觉得是,可是dbv检测又没问题,有些晕!
我的是dell服务器
ld0 ---> raid 5 100g
ld1 ---> volume 1 300g
ld2 ---> volume 1 300g
ld3 ---> volume 1 300g
系统启动时提示raid5 有错误 但是系统一直能用,
数据库装在ld1,数据文件在ld2 ld3.
准备在raid设置上再重新建一次,前提是数据库恢复了并做个备份(就是drop offline之后备份多少算多少了)
大家还有啥建议?谢谢 我菜
drop offline那2个数据文件(users012.dbf和users034.dbf)后,

数据能正常启动了,先做个备份,当然涉及到那2个drop掉的数据文件的表是不能访问了
