Tom,

Or,
- create a new tablespace
- ALTER TABLE {table_name} MOVE {new_tablespace)
- alter index {all indexes that belong to this table) rebuild

Hope this helps

Tom,

    Regrettably there is no way that you can drop a datafile from a
tablespace.
Your stuck with having to drop the entire tablespace.  If you can export and
import that's great.  Otherwise try creating a new tablespace, copying the
table
(with a new name) into the new tablespace, dropping the original table and
tablespace, and then rename the table back to it's old name.  Don't forget
the
grants as well.

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
