Drop temporal tablespace

Hi all,
I'm working with an 11.2.0.1 RAC. I need resize the temp tablespace. In order to do it, I've created a new temp tablespace with the correct size and I've configure it as default tablespace for database. After it, I try to drop the old temp tablespace but when I launch the drop sentence, it never finish.
I've take a look and I can see some inactive sessions are using the old temp tablespace.
How can I drop it? Any ideas?
Best Regards,
dbajug

>
I'm not getting errors if I try to drop the tablespace. I execute this estatement:
ALTER DATABASE DEFAULT TEMPORARY TABLESPACE TEMP1;
DROP TABLESPACE TEMP INCLUDING CONTENTS AND DATAFILES;
But it never ends. No error appears. After 20 minutes, I cancel the execution with a Ctrl+C.
>
Because there are sessions which still use space in old temporary tablespace .I don't think this sessions which already used old space in old temporary tablespace) can automaticly change from old t new .hence you have to choose one of the above ways

Why I got error ORA-02429 when I tried to drop a tablespace?

I use the following command to drop the tablespace:
drop tablespace users including contents and datafiles;The error message is below:
Error report:
SQL Error: ORA-00604: error occurred at recursive SQL level 1
ORA-02429: cannot drop index used for enforcement of unique/primary key
00604. 00000 - "error occurred at recursive SQL level %s"
*Cause: An error occurred while processing a recursive SQL statement
 (a statement applying to internal dictionary tables).
*Action: If the situation described in the next error on the stack
 can be corrected, do so; otherwise contact Oracle Support.However, I have removed all the tables and indexes in this tablespace.
Nothing found when I issued the following enquiries.
select index_name from user_indexes where TABLESPACE_NAME = 'USERS';
select table_name from user_tables where TABLESPACE_NAME = 'USERS';Is there anything I missed?
Thanks in advance.

As for your question
=================================================
Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to [url tahiti.oracle.com]tahiti.oracle.com.
Locate the link for your Oracle product and version, and click on it.
You are now at the entire documentation set for your selected Oracle product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab (for 10.x) or the "Master Book List" link (for 11.x) you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- Read a chapter a day from the Concepts Manual.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- When you have finished reading the Concepts Manual, do it again.

Cannot drop a tablespace

Hi,
A datafile of my database has been deleted from the OS and cannot be recovered. The related tablespace exits in the database.
I want to drop this tablespace, but oracle does not allow me to do so. I dont have the backup of the datafile.
Can something be done.

ANiL.

Hi
If your database is in archivelog mode and u have all the archive files than u can recover this datafile
no need to drop it or create the controlfile also.

Cannot drop undo tablespace with Active extents but no active sessions

Hi all,
I am running on 10gr2 oracle database in a Linux 32 bit environment.
I have a corrupted undo datafile. I've been able to recover the datafile but still the alert logs is still showing that it is corrupted.
Now what I'm trying to do is to drop the old undo tablespace like the one discussed here Change undo tablespace in Oracle - Switch Oracle's Undo tablespace.
My problem is I have an Active extent but no active session corresponding to it:
SYS@ccasdb AS SYSDBA > SELECT a.name,b.status
FROM   v$rollname a,v$rollstat b
WHERE a.usn = b.usn
AND    a.name IN (
                  SELECT segment_name
                  FROM dba_segments
                  WHERE tablespace_name = 'UNDOTBS1'
                 ); 2    3    4    5    6    7    8

SYS@ccasdb AS SYSDBA > SELECT a.name,b.status , d.username , d.sid , d.serial#
2 FROM   v$rollname a,v$rollstat b, v$transaction c , v$session d
3 WHERE a.usn = b.usn
4 AND    a.usn = c.xidusn
5 AND    c.ses_addr = d.saddr
6 AND    a.name IN (
7               SELECT segment_name
8               FROM dba_segments
9               WHERE tablespace_name = 'UNDOTBS1'
10              );
no rows selected
but still cannot drop the undotablespace.
SYS@ccasdb AS SYSDBA > drop tablespace UNDOTBS1 including contents and datafiles;
drop tablespace UNDOTBS1 including contents and datafiles
ERROR at line 1:
ORA-30013: undo tablespace 'UNDOTBS1' is currently in use

Yes i was able to recover the datafile but the alert_log kept on prompting that it is still corrupted. The datafile's status is online.
I want to kill the session/s contributing to the PENDING OFFLINE status of the rollback segment so I can already drop the undotablespace and so
that the alert log will stop prompting for that corrupted datafile in that UNDOTABLESPACE.
Can i Just alter the tablespace's datafiles to offline drop then just drop it. Then I drop the tablespace?

Drop Undo Tablespace taking more than 1 hr

Hi,
To give you background, I had given an "insert into .. select" command which was inserting 3 millions of rows of rowidth approx 5000 bytes. The window on which it was given, was closed by mistake.
After sometime when I checked the size of undo_tablespace, it was 5.5GB. I decided to create a new one and drop the old undo_tbsp.
I have successfully created new undo tablespace and changed the same in spfile also.
now when i am dropping the old undo tablespace, its taking long time. its almost an hour, but the tablespace has not been dropped yet.
I have given following command
drop tablespace undotbs_01 including contents;
Any idea, why is it taking so much time, and how long should I wait?
If someone can give me any other idea on how can I drop the tablespace, that will be great.
Regards,
Archana.

To give you background, I had given an "insert into .. select" command which was inserting 3 millions of rows of rowidth approx 5000 bytes. The window on which it was given, was closed by mistake.This could be the cause.
I wonder the killed/closed session doesn't hangup with a latch or lock.
Since the old undo tbs had active transaction, it might have to pending offline status. If so, you can drop it.

Drop Normal Tablespace Taking several hours

Hi,
In my 1TB database there is one tablespace size (38.5 GB / used 4 GB) which we used for objects backup purpose and i am trying to drop this tablespace using every option like bring tablespace offline and drop with DROP TABLESPACE TBS_NAME INCLUDING CONTENTS AND DATAFILES CASCADE CONSTRAINTS
but Drop Tablespace Taking several hours (24 + hrs)
I tried with drop objects from the tablespace but that is also taking lot of time to drop and then i tried to drop empty tablespace and again it is taking several hours.
Database version :- 10.2.0.3 and 10.2.0.4
Operation System Version :- Solaris 5.10
ERP 11.5.10
Please suggest what could be the problem.

So, till now you have done these steps,
1) dropped all database objects from that tablespace. Checked if any objects are there in this tablespace and there were none
2) take tbs offline
3) drop tablespace
4) While drop tablespace command is hanging, monitored segments in the tbs from another session. Segments were reducing very slowly
Out of first 3 steps, which step took longer? drop tablespace ?
Logically, when you are able to drop objects, then there should be no issue of locks or anything like that.
Dictionary updates should not take 24 hours!!!
What else is going on, on the disk/file-system where this tbs is housed?
Do you have all locally managed tablespaces?

Drop huge Tablespace

Hi Everybody,
Here there are some steps that leaded me into a dead end, where I would like and greatly appreciate some help.
1. We have a tablespace FONC, dictionary managed, 136Gb spliced in 11 datafiles
FONC1 to FONC11.
2. There it is a huge table in this tblsp, T1, 70GB, having BLOBs.
3. Some other tables are in it also.
My plan is to move all objects in this tblsp in a 2 new tblsp, one for the
BLOBS, one for the rest. And to drop this tablespace at the end.
I do not have enough disk space in order to have both tablespaces present in the
same time.
What I did.
0. ArchiveLog off.
1. Export the T1 table, the huge one (splitting the export in 24 files, placed
in all free spaces I found).
2. alter table move tablespace for the other tables.
3. start the Drop table T1.
4. after 6 hours, I stopped the drop, being short in time.
5. start drop tablespace FONC.
6. after another 5 hours, I cancelled this drop also.
7. tblsp FONC contains nothing else but a 67GB temporary segment.
8. took the tblsp FONC offline.
9. shutdown db abort.
10. delete datafiles FONC1 to FONC11.
11. startup db - no errors except a message in SMON Log - timeout waiting for a
tablespace management resource.
12. Create new tablespace.
13. Import table T1.
14. Archivelog ON - error ORA-265 - instance needs recovery.
15. Shutdown Abort.
16. Startup Open.
17. Shutdown Immediate.
18. startup mount.
19. ALter database datafile fonc1...11 offline drop.
20. Recover database - everything ok.
21. Alter ... ARCHIVELOG - same error.
22. Other trials - same results ...
No indications in any oracle log that SMON did an instance recovery, or other
error message.
Finally, the DB is operational, but ARCHIVELOG is OFF.
My problem is how to get rid of the FONC tablespace without loosing another xxxx
hours. A normal DROP tablsp including contents did not finished after 24 hours.
I need a way just to invalidate the temporary segment in the FONC tblsp, to get
rid of it, to be able to get rid of the tblsp FONC also. I guess that the
missing datafiles impede the instance recovery. An solution to be done when the
DB is online and in use is of course the most desirable one ...
using DBMS_SPACE_ADMIN can be more helpfull ?
Manually edit the controlfiles ?
Using RMAN ?
Thanks in advance, I appreciate what you are doing,
Dan

No I did not tried with Nologging.
On the other hand, what I see that takes long are the updates on the tables fet$ and uet$. More than that, a system session is issuing all the time blocking locks on this tables, that makes the drop to take so much time. Releasing 67GB in extents is quite challenging ...
So I need a way to lead only to delete on the fet$ and uet$ tables, and, a way to avoid the blocking locks. I thought that using DBMS_SPACE_ADMIN and invalidating the temporary segment first can be a solution.
The real problem here is that I can not do try-and-see, I can not stop the exploitation of the DB so I was hoping that somebody went through the same experience and has a working solution.
Thanks,
Dan

Drop a tablespace and datafile when database is mounted

I tried to import data in my oracle 11g. It failed midway. I presumed that i did not size the redolog properly. Now my database cannot go beyound the mounted mode.
ORA-01157: cannot identify/lock data file 7 – see DBWR trace file
ORA-01110: data file 7: ‘ /data1/owprojects/xxxxx.dbf ‘
Its a new oracle installation and i do not need the corrupt datafile.
I cant take the tablespace offline neither can i drop the tablespace including its contents.
Do i drop from the Linux OS. If yes which other file to i edit to remove the pointer to this tablespace.
Thanks and Best Regards
J

To drop a tablespace(with contents) in Offline mode

A test tablespace in the prod (24x7) was not required and to before dropping it I put it in the offline mode (with immediate option) to prevent further access.
The tablespace is not empty and presently in the offline mode.
Can I drop this tablespace ?
How?
I dont want to perform any recovery. Please suggest?
Thanks

Yes, you can :
SQL> create tablespace test datafile '/u01/ora92/oradata/ora9/test.dbf' size 10M;
Tablespace created.
SQL> create table test01(a number) tablespace test;
Table created.
SQL> alter tablespace test offline;
Tablespace altered.
SQL> drop tablespace test including contents and datafiles;
Tablespace dropped.
SQL>You can even do it with the tablespace online :
SQL> create tablespace test datafile '/u01/ora92/oradata/ora9/test.dbf' size 10M;
Tablespace created.
SQL> create table test01(a number) tablespace test;
Table created.

Dropping Undo Tablespace 9i

Hey Folks,
I really need some help here.
I'm trying to drop/recreate the undo tablespace (currently 25gig) Oracle 9i
When I try to drop the undo tablespace 'UNDOTBS1' I get the following error:
âORA-01548: active rollback segment '_SYSSMU1$' found, terminate dropping tablespaceâ
Here's what I have tried so far:
- Bounced the DB several times hoping to get rid of the reference to the active rollback segment. No luck.
- Created a new undo table space
- Tried 'Alter system set undo_tablespace=new_one' (noticed that 10 new rollback segs were created '_SYSMU11$..SYSMU20$' pointing to the new undo tablespace)
- I then performed an offline drop of the undo tablespace data file. After the offline drop, the system rollback segs SYSMU01$..SYSMU10$ went offline as would be expected.
- Even with the new undo tablespace, all other application tablespaces still use the old undo which due to the offline drop, no inserts, deletes, etc. will work.
After all the above, I still get the same error when trying to drop the undo tablespace.
Any ideas? Ideally I would like to be able to drop the undo tablespace and recreate it, but at this point I'd be happy to bring back the undo tablespace datafile so we can at least use the database again.
Thanks in advance!!
Colin

SQL> show parameters undo
undo_retention integer
10800
undo_suppress_errors boolean
FALSE
undo_tablespace string
UNDOTBS03
r.- The undo tablespace which the database is looking for is this one ( UNDOTBS03 )
What is strange about the lines above is that I have
all those params above commented out in my
\pfile\init.ora file (and have bounced the db).
Iâm not sure why they are still showing up.
r.- Perhaps your instance is started with the spfile instead of the init file
Here's what we did after the UNDOTBS1 tablespace
caused the disk to run out of space during a large
import (from now on we are going to use commit = y):
1. Created a new undo tablespace UNDOTBS03 - got
errors so instead we to created it as a temp
tablespace UNDOTBS03 which worked. r.- Yes, but that tablespace was created as a UNDO TABLESPACE ?
2. Tried to drop UNDOTBS1 got the following error
msg:
ORA-01548: active rollback segment '_SYSSMU1$' found,
terminate dropping tablespacer.- Of course, the database did not allow to drop it beacause there were pending transactions
3. SQL> alter system set undo_tablespace =
'UNDOTBS03' scope = both. Tried dropping UNDOTBS1.
Same error as in #2 above.r.- There were still pending transactions with the older undo tablespace
4. We then offline dropped the datafile associated
with UNDOTBS1 hoping that would then allow us to drop
UNDOTBS1. Same error as #2.r.- That was the worst you did. You can not drop a tablespace so...
5. Then tried creating a undo tablespace again:
Create UNDO tablespace undo_temp
datafile 'D:\oracle\oradata\usbperf\undo_temp.DBF'
size 25m autoextend on;
Error on line 0
Create UNDO Tablespace undo_temp
datafile 'D:\oracle\oradata\usbperf\undo_temp.
ORA-00604: error occurred at recursive SQL level 1
ORA-00376: file 2 cannot be read at this time
ORA-01110: data file 2:
'D:\ORACLE\ORADATA\USBPERF\UNDOTBS01.DBF'
So thatâs where we are. I'm guessing that the
original undo tablespace corrupted when it tried to
extend and ran of disk space?
Thanks again for the help.
Colin ok I can guide to solve this but you have to do what I am going to tell you step by step. Is this a production database ?

Drop undo tablespace

Tive que criar uma segunda undo tablespace, mas agora não preciso mais dela. Posso apagá-la normalmente com um drop tablespace ou tenho que fazer alguma verificação antes? Ela não é mais a undo tablespace da instância.

People here have made a great effort to reply to your post. You could try those on-line translators to translate from Portuguese to English, instead of letting the posters translate your request.
On the other hand, once you have created a second undo tablespace which is no longer requried, just drop the tablespace, assuming you have not declared this as your database undo tablespace at the UNDO_TABLESPACE instance parameter. You may issue the command:
drop tablespace yourUndoTablespace including contents and datafiles;
and you are done.

Drop Temporary Tablespace!

Hi All,
I have tried dropping my old temporary tablespace TEMP after making new TEMP2 as default.
All the users (checked in dba_users) are using TEMP2 as default temporary tablespace.
Now, issue is when I am trying to take TEMP offline and dropping it some of the users are not able to open the forms.
Please suggest, is it necessary that I must do this activity after taking a proper downtime or I can do it in business hours.
Thanks,
Anchorage

It's done now!!!
Actually issue was
You cannot drop a tablespace if it contains any rollback segments holding active transactions.*
Try to check whether any one using the temp segments or not on query "v$sort_usage"*
If it returns the rows, the sessions are using the temp tablespace. Once the Sessions Closes then the the command execution will be completed, else you and go head and kill the session with respect to session Id.*
Which was been explained to me by Pavan in General Database Forum!
I have killed the active session and it was success!
