This is a simple question to you, but I just wanted to confirm it before changing anything on the live DB.

Question : Can I add more datafiles  to a new drive just got created while system is online? Does it make any performance impact? Do I have to restart the server? Any concerns?

This is the production system.

Thanks,

~Sve.

yes you can add datafiles to exsisting file gorups on an online system with no worries.
no performance degradetion will occour as long as you dont initialize the file with a TOO large value.

Good Luck
