Oracle Database Discussions

I accidently deleted some datafiles that were part of a tablespace. I don't care about the data because I had not yet used these datafiles. But when my database won't startup because it has the following error in the trace file.

I dont have a back up of these files.

How do I solve this problem.

Thanks
Venkat
