Thanks, Winnie! It works.

I have a further quetion. If the archivelogs from time when the file was created to current were lost, do we still have someway to bring the file online?

Umm.. Try this:

  1. ALTER DATABASE DATAFILE 'filename' OFFLINE;
  2. get rid of the offended datafile from OS
  3. ALTER DATABASE CREATE DATAFILE 'filename(same as 1)';
  4. RECOVER DATAFILE 'filename';
  5. ALTER DATABASE DATAFILE 'filename' ONLINE;

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.
