Re: How to drop a datafile from a tablespace quickly
you wrote: < there to claim his 42 virgins in Paradise?> This is a common mistake. Read the following to know the truth: Humor . . . bin Laden's fate? After getting nailed by a Daisy Cutter, Osama made his way to the Pearly Gates. There, he is greeted by George Washington. "How dare you attack the nation I helped conceive!" yells Mr.Washington, slapping Osama in the face. Patrick Henry comes up from behind. "You wanted to end America's liberty, so they gave you death." Henry punches Osama in the face. James Madison comes up next and says, "This is why we allowed the federal Government to provide for the common defense" and kicks Osama in the groin. Osama is the subject to similar beatings from John Randolph of Roanoke, James Monroe and 67 other people who have the same love for liberty and America. As Osama writhes in pain on the ground, Thomas Jefferson picks him up and hurls him back to the gate to be judged. As Osama awaits his journey to his final very hot destination, he screams "This is not what I was promised!" An angel replies "I told you there would be 72 Virginians waiting for you. What did you think I said?"

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

Yeah, I have missed every OOW since then. Just not worth it compared to
IOUG.
I could have sworn I saw some Perl-looking DBA standing on the corner with
his eyes wide and mouth hanging open when she flung that car and her
passengers around.
BTW, when is that Perl/Oracle DBA book coming out. Heck, I'm still trying
to figure out how to write a loop in Perl...can't I just replace all those
strange characters with words?

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

RE: How to drop a datafile from a tablespace quickly
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;

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

Please respond to

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

RE: How to drop a datafile from a tablespace quickly
No easy way to drop a datafile.
Your best bet would be to resize the datafile to a very small size
( eg 10k).
(This will cause a trivial performance overhead since it has to
checkpoint an extra
file. But not even worth mentioning)
And then add another datafile to this TableSpace or rebuild the
tablespace when
you have some time with the appropiate size datafiles.

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

Re: How to drop a datafile from a tablespace quickly
AFAIK you can't "quickly" drop a datafile. What we have done in this situation is to resize the datafile to 1 byte or however small you can make it. That way oracle can never write an extent there. Then do the export/drop tablespace/import routine at your next maintenance.

Re: How to drop a datafile from a tablespace quickly
Scott, Did you hear that Douglas Adams was asked recently (i.e. a few years ago) how he knew the "Hubble Constant" was (roughly) 42, back when he wrote the "Hitchhiker's Guide To The Galaxy" series back in the 60s and 70s? The Hubble Constant (having to do with the rate of expansion of the universe, I think) had just been discovered to be 42, sometime in the mid-90s, I believe... His response was something along the lines of "Well, actually I didn't know, of course. It's just that I needed an answer to the question 'What is the meaning of life, the universe, and everything?' and 42 seemed like an appropriate answer. Just an ordinary, sort of smallish number"...

RE: How to drop a datafile from a tablespace quickly
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.

RE: How to drop a datafile from a tablespace quickly
Rachel, you said "It's not just grants. Any procedure that references that table will have to be recreated, oracle uses object_id not object_name so the procedure will point to the old table etc etc" Can't he just re-compile the procedures? He doesn't have to re-create them.

RE: How to drop a datafile from a tablespace quickly
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;

RE: How to drop a datafile from a tablespace quickly
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

RE: How to drop a datafile from a tablespace quickly
No. Get some downtime, quickly(!) before data does get written to that file. Go through the export/drop tablespace/recreate. BTW, do you know _why_ the file header is corrupted? Is there a disk hardware problem? You are gonna have downtime sooner or later. Tell damagement to get over it.
