problem: how to restore from a different drive, note impoossible to use rename file there is about 1500 dbf's

Background:

I am a trainee dba,Our sysadmin recently CAHNGED the drive letter assigment will be replaced OF OUR SERVERS.

When I tried to recover the database and since I have a very acceptable backup of the files, I just copied it to the assigned drive.

I started the DB, and error occured it seem that it cannot locate all my files

But upon checking the V$DATAFILE, the drive letter that was reflected was the old drive letter.

How do I change this I have 1500 dbf it will take long time to restore this, it should be up at least tom.


Help Please, are there scripts or anything that can help me??

thanks
