I have one doubt.Take the below case

Suppose our database have 100 datafile and right now rman has completed backup of 64 datafile and in process of backup of 65 number datafile.In mean time I excuted some query and it has changed the block 55. so now my question weather rman will go and bacup this datafile again or it will leave this file as it is and archive file will be having info about this file.

Hi,

It was a great explanation, thanks a lot. I have a question, as the datafiles headers are freezed while taking backup when the SCNs are updated… For example if hundreds of transactions have performed then how the SCNs are updated. Plz clarify my doubt. It would be great favour to me and other DBA’s.
