Tell me one thing that when v run ur DB in archivelogmode.
when ever a archivelog is generated. where it updates. In the control file kya.

And in this case suppose v lose the controlfile also then how can v recover our DB. I think v h to recreate the controlfile?

If I want to copy latest controlfile and archivelog file and with this I want to recover another database. can I do this. (o other database i hv already kept online backedup files)
