Ashish, I've looked through your previous messages trying to work out what you are doing. It looks as though you are trying to teach yourself backup and recovdery rechniques. If so, your first step must be to read the manual, http://docs.oracle.com/cd/E11882_01/backup.112/e10642/toc.htm
Then a sensible way to proceed is to perform a backup, and then simulate various problems, such as losing a datafile; or a controlfile copy; and so on. Then try to restore and recover. The Data Recovery Advisor (chapter 15) can be a useful tool: it will generate scripts for you, but don't just run them, look at them and understand them. You can often improve on them.
Why don't you try it on your database now, and see what it recommends?

...Then when you have a question like that COPY AND PASTE what you did and got.
It is very to tell what is wrong with just an error message.
