Home -> Community -> Mailing Lists -> Oracle-L -> RE: How to drop a datafile from a tablespace quickly
Tom,
If you lost an archivelog from the time this datafile was created to present time. There is no way to simply offline that file and recover that file. It will become a classic case of performing incomplete recovery then.
Glad that it works out for you! :D

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?

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
