Hi,

1. My database is up and running since morning 9 O'clock.
2. I have three disks and in the first disk I have only master
control file (i.e the first control file in the Init controlfile
list).

Ques 1. If at any cost, my first disk will crash at any time(I don't
know when it has opened) does my Database will throw any
ERROR when the database is up and runing?

Ques 2. Secondly, if I will copy the control file from the other disk
to it's original first disk, will it give any problem to open
my database?

Regards
