Hi,
when show full the tablespace i can't resizeDon't worry, see this other thread : Re: can not create table...!
It's better do not to use an autoextend file for temp tbs.

Increasin the temp tablespace

Hello All,
I am using Oracle 11g R2 i want to increase the temp tablespace size. can i use the below command? can i increase while the database is open and some queries are running and use the temp table space?
ALTER DATABASE TEMPFILE '....../datafile/name_datafile.tmp' RESIZE 100M

Hello,
I am using Oracle 11g R2 i want to increase the temp tablespace size. can i use the below command? can i increase while the database is open and some queries are running and use the temp table space?Why do you intend to extend the Temporary Tablespace ? Do you have any ORA-01652 error ?
If not, may be it's not necessary to extend it. Even if it seems to be full Free Extents are reused.
ALTER DATABASE TEMPFILE '....../datafile/name_datafile.tmp' RESIZE 100MYes you can use this statement, but be aware that the Size specified (here 100 Mo) is the target size not the supplemental size.
Hope this help.

How to add a datafile in the temp tablespace

how i can add a datafile in the temp tablespace.
becuase i am getting tyhe following error
SQL> select aa.question_desc,a.answer_desc from answer a ,
2 (select * from question_t where rownum <=100 order by dbms_random.random) aa
3 where a.question_id = aa.question_id
4 /
select aa.question_desc,a.answer_desc from answer a ,
ERROR at line 1:
ORA-01652: unable to extend temp segment by 256 in tablespace TEMP

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 : 
SCOTT@demo102> select ename from emp where rownum<=5 order by dbms_random.random;
ENAME

Any way to avoid the hit on the TEMP tablespace?

I'm running a CTAS query that unions 13 tables with about 7,000,000 rows each, inner joins that union again against a global temporary table with 13 rows, and then doing a GROUP BY against the result, summing about 6 fields. The resulting query runs in about 2 hours with about a 16 Gig hit on the TEMP tablespace.
In production I will need to join 52 tables with about that many rows against a GTT with 52 rows. I haven't experimented with it yet but I'm guessing the time and memory increase will be linear (i.e. 8 hours, 64 Gig hit).
I'm being asked if there's any way to avoid the hit on the TEMP tablespace. It was suggested that I look into using a materialized view, but won't that just transfer the hit from the harddrive to the RAM? I don't think this particular database has 64 Gigs of RAM dedicated to it, and I'm sure the row counts will grow in the future anyway.
Thoughts?
Thanks
Joe

I don't have visibility to the TEMP tablespace on their database so I don't know if the hit there is any less.
If you have privileges you can use SQL*PLUS autotrace (or possibly Oracle trace, if you're really that interested) to get run-time statistics on a query as you run it. Waiting for the 2-hour results will be a bit tedious though. If you don't have privileges for autotrace it won'r work; the error messages explain what's wrong rather well ;)

Cleaning up temp tablespace with out restarting Oracle instance.

Hi,
I've a scenario where my temp tablespace gets filled up and i rarely restart my Oracle instance.
My temp tablespace is not auto-incremental and the Oracle version i have is 9.2.4
Appreciate if any one can provide the answers/suggestions?
Thanks.

Thanks for the reply...
I gone through the thread on Jeff Hunter where he is altering by making the temp table space to auto increment.
But my tablespace an i can't change my tablespace to autoincrement since it is in continous use 24x7 and 365 days.
Any ideas please?
Thanks

Sizing of the OLAP temp tablespace!!

We are using 10gR2 OLAP along with Disco Plus OLAP to build a prototype. The metadata is built with AWM 10.2.0.1.0A.
Our test data is about 40M records, 1.7G in a flat file. After loaded to a fact table via Sql*loader, it takes about 2G for the tablespace, along with 7 dim tables. Only one cube and one measure are used. A compressed composite with 6 dims in it is associated with the cube.
However, when run the AWM maintenance steps to get a full cube aggregation. The temp tablespace for the AW shot for 30G and then generated an out of disk space error. The AW tablespace remains untouched. The maintenace cannot be finished.
Interesting to note, the data was solved in the Xpress already. When do a eif exp/imp, the result tablespace is about 5G while the eif file takes 1.3G.
Also, before doing this round data, we have sucessfully created and maintained a AW with very small set of data. The data is displayed in Disco Plus correctly.
The disk space for the temp tablespace seems surprisingly demanding. We need to get an idea how much space it really needs. Is there anybody that has some contributable experience on this issue? Please reply this post. Not sure if Oracle has formal publishing on the temp tablespace sizing issue. Believe they should have one.
Thanks,

Chris,
No upgrading was done here. The metadata and objects were defined using AWM model view manually, but matching to the definition on the Xpress side for the same object, like dim order etc. The fact data then dumped to a flat file from Xpress, transferred to the olap db server and loaded to a star schema with sql*loader. AWM mapping and maintenance features were used to build the cube.
I am saying the data was solved means the summary level data was included in the dump. So we know the size of the solved cube. My reasoning is that there should be no place for the size increase to out of control because too much new summary level data was added.
Another fact I should mention last time is all the data are in one time period. 40M is the number of tuples.
Thanks for the help.

9i on Linux. Problems with Temp tablespace cleanup

I am currently running Oracle 9i Enterprise on SUSE Linux 7.2.
I am executing queries against the new XMLType datatype and every query adds to the Temp tablespace, which doesn't get cleaned up. Eventually, the tablespace will run out of space and Oracle will issue and error:
ORA-01652: unable to extend temp segment by 128 in tablespace <name>
The only way to clean up the Temp tablespace seems to be by restarting the server.
Is that happening on other platforms as well? I would appreciate any help.

Hi
You can connect to the database as DBA (Sys or System) and make a bigger temporal tablespace. Or create a new bigger temporary tablespace and assign it to the user.
A10!
PS: Temporary tablespace is used when no memory available for the session, for example when a big ORDER BY is done. Try to increase the memory assigned, just look at initXXX.ora (sort_size)

What should be idea temp tablespace size ?

HI all
My databases size in between 20 gb to 100gb. waht factor should i consider to fix the temp tablespace size ?
What should be my ideal temp tablespace size for the both database ?

Temp size wont depends on database size, It purely depends on user sortings. Create the temporary tablespace with autoextend upto maxsize of 32gb approx & see how users performing sortings.

Releasing TEMP tablespace segments

Hi All
Due to some SQL Queries, the temp tablespace is getting full. I want to release the space in the TEMP tablespace by a command. I know SMON does it (correct me). I have Oracle 9i, and the TEMP tablespace is a local tablespace.
Any help will be appreciated.
Thanks
Bala

temp segment is full may be normal...you need to add some space! well, you can't clean the temp segments when it is used by some running process! smon allocates and deallocates space in temp segment, users doesn't have any control!! how did you define the temp segments...temporary or permanent? and why smon is not doing the cleanup...couple of stack dump of smon would be helpful. you can use any debugger in your system to dump the stack.
Thanks,

TEMP tablespace getting full while inserting a CLOB in Trigger

We have a Oracle 10g (10.2.0.4.0) DB on a Solaris 9 box which also runs our J2EE web-service application on Weblogic 8sp6 server.
We get around 220K web-service requests from upstream callers daily to insert data in the main table, say TABLE1, which has daily partitions on a date column. This table has around 21 columns out of which 1 is a CLOB column.
Now this table has an AFTER INSERT trigger which calls a package procedure to insert the same record into another table, say TABLE2.
From Java application insert statement in executed in below format using a weblogic jdbc connection pool :
INSERT INTO TABLE1(COLUMN1, COLUMN2, ........., CLOB_COLUMN,........, COLUMN21) VALUES (:1, :2, :3, :4, :5, :6, :7, :8, :9, :10, :11, :12, :13, :14, :15, :16, :17, :18, :19, :20);
Clob object is prepared in application using ojdbc14.jar.
We are observing a strange issue here. The TEMP tablespace utilization keeps on growing as more and more inserts are executed by application and after ~125K inserts the TEMP tablespace gets full and we start getting ORA-01652 error.
On further analysis we could see that there are only 7-10 session being maintained but as more and more inserts happen TEMP tablespace utilization goes on increasing for each of these sessions.
When we tried with inserting just few records and then watching the session details in v$session_wait then we could see that it is in INACTIVE state and waiting for the event ‘SQL*Net message from client’. This does not seem correct as the session has successfully inserted the data and committed the transaction and we can see the data in the tables as well.
The confusing thing here is when we modify the trigger to pass blank string('' ) instead of the CLOB column to TABLE2 then this issue does not occur. All 200K records are inserted properly and TEMP tablespace utilization also keep always below 1%.
Can you please help us in solving this issue. Is this related to any oracle issue?
Inside the package we have tried using DBMS_COPY statement to copy the CLOB column after insert but still same result.
Code for reference:
Trigger:
=====================================
CREATE OR REPLACE TRIGGER trg
AFTER INSERT OR UPDATE
ON TABLE1
REFERENCING NEW AS NEW OLD AS OLD

end;
=====================================

My first thought on reading your post is that not only are you using a database version that is now so old it is in extended support and even then not even the most recent patchset for it.
The first thing I would do is move to 11gR2 and if you can't do that at least get to 10.2.0.5 and apply CLOB relevant patches as well.
Same goes for your operating system. Solaris 9 is ancient: So move to 10 which has vastly improved memory management.
To help you further it would be really valuable to know the table layout. For example is this a heap table or an IOT? Is it partitioned? Is this RAC? What size are the CLOBs? Are they stored in-line? Chunk size? etc.
This page should start you down the right road:
http://docs.oracle.com/cd/B19306_01/appdev.102/b14249/adlob_tables.htm#sthref204
But I am also wondering why you would use a trigger to, as you say, "insert the same record into another table." This description is a poster child for "bad design."

How can I know which queries run in the TEMP tbs (Oracle 9i and 10g) ?

Dear friends, do you have a query which can shows which statements are running currenly in the TEMP tablespace?
Many Thanks in advance, Marcelo.

Marcelo,
you can check DBMS_XPLAN.DISPLAY_CURSOR - if you find a column TempSpc there, it's using Temp space.
select source from sys.source$ order by source;
select * from table(dbms_xplan.display_cursor(NULL, NULL, NULL));
PLAN_TABLE_OUTPUT
SQL_ID 5ywbw0z6gupwk, child number 0
select source from sys.source$ where rownum < 555555 order by source
Plan hash value: 1381731087
| Id | Operation | Name | Rows | Bytes |TempSpc| Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | | | | 11492 (100)| |
| 1 | SORT ORDER BY | | 555K| 37M| 87M| 11492 (1)| 00:02:18 |
|* 2 | COUNT STOPKEY | | | | | | |
| 3 | TABLE ACCESS FULL| SOURCE$ | 572K| 38M| | 1834 (1)| 00:00:23 |
---------------------------------------------------------------------------------------or for all your statements currently available:
SELECT t2.*
FROM v$sql s, table(DBMS_XPLAN.DISPLAY_CURSOR(s.sql_id, s.child_number)) t ,
 table(DBMS_XPLAN.DISPLAY_CURSOR(s.sql_id, s.child_number)) t2
WHERE t.PLAN_TABLE_OUTPUT like '%TempSpc%';Edit: Sorry, I didn't see you are also asking for 9i. DISPLAY_CURSOR is only available in 10g+ - but Tom Kyte and others have shown WorkArounds to use DBMS_XPLAN.DISPLAY from 9i to show the information for all available SQLs.
2nd Edit:
TempSpc only shows the estimation the optimizer makes.
You can check V$SQL_PLAN_STATISTICS_ALL for the columns max_tempseg_size and tempseg_size. In Addition please have also a look on [http://antognini.ch/about/] Blog [http://antognini.ch/2009/05/wrong-information-about-temporary-space-usage/] .
I used:
select PARENT_ID, ID, DEPTH, POSITION,
 MAX_TEMPSEG_SIZE, LAST_TEMPSEG_SIZE
from v$SQL_PLAN_STATISTICS_ALL
where MAX_TEMPSEG_SIZE > 0;hth,

Need help on extending my TEMP tablespace (Ora ver - 8.1.7.0.0)

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.

Informatica Workflow fails because of TEMP tablespace

Hi,
I am trying to do a Complete Oracle 11.5.10 load. However my execution plan fails because the SDE_ORA_Payroll_Fact fails. The error in the session log is as follows:
READER_1_1_1> RR_4035 SQL Error [
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
From the error message it is very clear that the Source Qualifier is unable to select the data from the source tables. i have increased the TEMP tablespace too however I keep getting the error. Because of this error my other mappings are also Stopped. Any solutions to this problem?

Hi,
Would you not want to use the following parameters to say load one fiscal year at a time?

Cleaning up temporary tablespace

Hi,
I am facing a problem where temporary tablespace of the production database has grown to 23GB.The instance cannot be bounced and there is very little space left for the rest of the database.I want to free up the excess space.I know I can do it by creating a new temp tablespace,assigning it as default and dropping the old one.But I want to know how I can resize the existing temp tablespace.when I try the following command:
alter database datafile '/d02/oradata/<SID>/temp01.dbf' resize 1G;
it gives the following error:
file contains used data beyond requested RESIZE value.
How can I get around the above problem.there is no session using TEMP tablespace.Plz suggest a solution as I really want to know how this can be done.

First of all, You can't resize the temp tablespace datafiles size as once the temp tbs allocate extents, after the operation finishes, oracle won't deallocate them as it keep them for future requirements and usage.
What you can do in your case, as you cant bounce the db, create another temp tablespace and assign it as default temp tbs and drop the old one.
Also, dont keep its datafiles for auto extend and if you see any error message in alter log file like 'unable to extend temp tablespace' then increase the size. If you feel your queries may fail due to this, you can also use resumable option and investigate why does it requred 20+G for temp?
