How could I extend temp tablespace safely ?

I am beginner of Oracle DB.
We are making DEV environment of Oracle Insight.
How could I extend temp tablespace safely ?

It is normal to see the temp tablespace full. Oracle finds it the most efficient way to allocate an extent and mange it rather than allocate - deallocate.

How do I empty TEMP tablespace in Oracle8.1.7.4

Unable to extend Temp

HI
Each night we have a job that runs to rebuild indexs that meets a certain criteria.
Lately we have been getting
ORA-1652: unable to extend temp segment by 5120 in tablespace [MY_INDEX_Tablespace]
However, at the time of last night's error, the Temp tablespace had been dropped and recreated and had two empty datafiles, each 3 gigs. Notice in the error that it list our Index Tablespace. The Index table has just over 2G free. The error states the temp segment could not extend by 5M. I don't understand this behavior or this error.
Can anyone add insight into this error? Thanks.

Hi Madrid
I had a feeling that might be the case, but I can find no info anywhere on whether oracle allocates temporary extents within a permanent tablespace, in this case, INDEX. Especially considering that the temp tablespace was recreated with AUTOEXTEN OFF due to bug 2193406. so it was odd to see a "could not extend temp tablespace" error on a tablespace where AUTOEXTENT is off.
The index rebuild is vendor driven. They run a sp that checks for index hight and other criteria. If a index meets their criteria, it is rebuilt. I am fighting to move this to once a week and also to use tablespace with larger block size - we'll see how that goes <IMG class=jive-emoticon border=0 alt=:-) src="http://forums.oracle.com/forums/images/emoticons/happy.gif">

ORA-01652: unable to extend temp segment by 256 in tablespace HDM_DBUSER_TEMP
HI GURUS PLEASE HELP ME,
I Have 9i database on solaris version 9,
i am repeatedly getting the following error in the alert.log file.
Failed write to clobORA-01652: unable to extend temp segment by 256 in tablespace HDM_DBUSER_TEMP
using the meta link Doc ID:     280578.1, i have increased the temp TS, but still getting the same alert message in alert.log file.
In metalink it is given second solution,
If there is severe temp segment space contention across instances, a
slowdown can occur. The following are potential workarounds:
- Increase size of the temp tablespace
- Do not use the DEFAULT temp tablespace feature in RAC.
- Increase sort_area_size and/or pga_aggregate_target "
I have increased the size of the temp TS, but the error is poping up still in alert.log.
I don't know how to assign DEFAULT temp tablespace feature in RAC????

TEMP Tablespace Groups

In Datawarehouse environment, Database verion 10gR2:
Created two temp tablespaces TEMP1 and TEMP2 with 10GB each in a temp tablespace group(TEMP_GROUP) and assigned the TEMP_GROUP as default temporary tablespace to user "BATCH", expecting the batch user can use 20GB of temp tablespace.
When a process needs a temp tablespace of more than 10GB, the process fails with an error unable to extend temp tablespace. It is not utilizing the other 10GB TEMP tablespace.
When I assign a dedicated TEMP tablespace TEMP3 with 15GB as the default temp tablespace, the process succeeds.
It looks like when a session starts it assigns one TEMP tablespace(from group), if that fills up it is not taking advantage of the other TEMP tablespace in the group, which makes me think that Groups are not helping here.
Is there an other way around to utilize multiple temp tablespaces for a single user.
Can we expect an improvement of this feature in the future releases or is that not a possible scenario?

-- Using a tablespace group, rather than a single temporary tablespace, can alleviate problems caused where one tablespace is inadequate to hold the results of a sort, particularly on a table that has many partitions. A tablespace group enables parallel execution servers in a single parallel operation to use multiple temporary tablespaces.
CREATE TEMPORARY TABLESPACE TEMP2 TEMPFILE '/u10/oracle/oradata/dbt1/datafile/temp02.dbf'
SIZE 20M
TABLESPACE GROUP tempgroup1;
CREATE TEMPORARY TABLESPACE TEMP3 TEMPFILE '/u10/oracle/oradata/dbt1/datafile/temp03.dbf'
SIZE 20M
TABLESPACE GROUP tempgroup2;
ALTER TABLESPACE temp TABLESPACE GROUP tempgroup1;
select * from v$tempfile ;
select * from dba_tablespace_groups ;
alter user ABCD temporary tablespace tempgroup1 ;
-- Verify that temp group is assigned to user
select * from dba_users where username='ABCD' ;
After you assign the group to the user abcd then retry your operation as abcd user.
This time it will use both the temporary tablespaces for sort operations.

Droping TEMP tablespace

hi folks,
i have a production database in a high traffic environment base on oracle 8.1.7.0.0
i lost TEMP tablespace's datafile because of that i just offlined the tablespace ( just one datafile per tablespace TEMP ) but i can not drop or add a datafile to this tablespace.
i just added a TEMPX tablespace and changed TEMPORARY TABLESPACE of users to use this new temporary tablespace.
really how can i renew TEMP tablespace?
thanks in advanced

Well, the tablespace's offline. ok. Is it a TEMPORARY TABLESPACE or a PERMANENT with TEMPORARY option?
Can you issue the queries:select tablespace_name,file_name from dba_temp_files where tablespace_name='TEMP';
select tablespace_name,file_name from dba_data_files where tablespace_name='TEMP';to check this?
OEM show the used space because it checks in some data dictionary views which still contains info about the TEMP tablespace.
You should really try dropping the datafile/tempfile first via "ALTER DATABASE DATAFILE 'filename' OFFLINE DROP" before dropping the tablespace.
You should also check the status of the session in which you drop the tablespace before cancelling. It may take some time to complete.

Hi,
I am using 10g RAC Database. Its an 3 node RAC infact 2 nodes are active. Today i found some temp segment related error in my alert logfile.
ORA-1652: unable to extend temp segment by 128 in tablespace
After some time the error disappeared. When i checked the space availbility in that temp1 tablespace its showing enough space (almost 13 gb is free from out of 15 gb).
Could pls tell me why this error occured?

As William pointed out, the total amount of free space is not very revealing. Also, there are potentially more things in tablespaces than tables. Try these two queries to get a better picture of what space you have, and what is in the tablespace.
SELECT file_id, MAX(bytes) biggest, SUM(Bytes) total
FROM dba_free_space
WHERE tablespace_name = 'PROD_REV_FACT_TS';
SELECT segment_name, segment_type, owner, bytes
FROM dba_segments
WHERE tablespace_name = 'PROD_REV_FACT_TS';For a really detailed view of free_space you could try:
SELECT file_id, block_id, bytes
FROM dba_free_space
WHERE tablespace_name = 'PROD_REV_FACT_TS'
ORDER BY 1, 2;It sounds like you are trying to create a table or an index in that tablespace, and running out of space. When you do that, Oracle initially builds the segment as a temporary segment. When the segment is fully built, the temporary segments are changed to permanent segments. This makes cleanup easier for Oracle if the database goes down in the middle of the operation.

I get the above listed error. And i assumed there may be some issue due to Temp tablespace. I also verified the space occupied by the TEMP tablespace and it was 99% occupied.
Kindly let me know is there a way to extend the space without affecting the existing DB content
Regards
Srinivasan B

Didn't you got a answer in your Getting error while executing the SQL ( ver 8.1.7.0.0), did you ?
Furthermore, don't worry about the TEMP tablespace utilization, Oracle doesn't freed space until you need it. By the way, how your TEMP tbs is defined (AUTOEXTEND, DATAFILE/TEMPFILE...) ?
Anyway, you have to be sure about the free space on your device. And check on metalink website to get some notes advices.

Thanks in advance

create tablespace or add index, that you can find out at http://tahiti.oracle.com
You should check space on CDR_TAB.
I think you can create new tablespace

select * from question_t where rownum <=100 order by dbms_random.random After all the discussion about random select a random generated number... why don't you go for one of the suggestion like : 
select *
from (select * from question_t order by dbms_random.random)
where rownum <=100 The result is different. 
In your query, you take 100 rows and order randomly, in the second query, order randomly, and take 100 first rows... 
As you can see above, with your last query, output row are always same, but in different order :
