Home -> Community -> Usenet -> c.d.o.server -> REPOST: Re: Lost oracle database but have the datafiles
Ah, well that is the problem I only had those files not all. The
system became corrupted when the HD failed as did the rest those
where the only 2 file I copied previously.
I htink I got yeah. Next time I will be more careful and make darn sure I have a automated backup system.
First time is ok the second time Im an idiot.
Thank you again!
