Since there is no data in the file, can we make a datafile to replace it?

There is absolutely NO WAY to drop a datafile from a tablespace at all.

Please respond to
ORACLE-L
Dear gurus:
I just added a data file to a big tablespace (11GB) that has only one
table. Unfortunately, when it was being backed up, the file head head
corrupted. I don't have any backup of this file. I found that there is
no data in this file yet. So I want to drop the file from the
tablespace. As I know, to drop a data file, I have to export the data,
drop the tablespace and recreate it, and then import data back to
the tablespace. However, since our users can't stop using the table,
I won't have enough down time to do that.
Is there anyway I can quickly drop a data file from a tablespace?
Don't tell me using "alter database datafile '...' offline drop" command.
It won't work.
I am working on Oracle 7.3.4.
Thanks,
Tom Xie
