Dear Khurram,

Actually I posted this thinking that this is a media recovery only and we lost control files because of media failure. However this can be a case of instance recovery as well once we re-create the control files.

Dear Advait,

Please refer this thread with instance recovery not only recovery which create confusion for new comers.When i was reading initially i was assuiming you are going to demonstrate about media recovery but it is instance reovery which oracle automatically does itself.

Thanks

Hi Jacky,

I think you are right, its checking from controlfile and not the datafile header. Thanks for pointing out that.

Hi Advait,

was wondering whether you mixed “datafile header” and “controlfile”? such as “but stop SCN # in datafile header is NULL. “?

thanks.
