Who is using all Temp Tablespace

Hi,
Temp TS is 80% full and I want to see, who is using this lot space ?
It might be an uncommited, not rolled back statement, but what session is it ?
v$sort_usage does not show any result.
Documentation does not recommend Quota on Temp TS, since temp-objects belong to sys.
How to limit a users comsumtion of temp TS for bad statements ?
Thanks for any tip Lao De

I believe it is normal for a well-used temporary tablespace to have this level of usage. Once space has been allocated in a temporary tablespace the system manages it. This behaviour should show up in the DBA_FREE_SPACE view - all the extents in that tablespace will be marked as FREE.
If you "free up" - release - space in the temporary tablespace you are in effect asking the database to do additional space allocation the next time a sort has to be done. All you've acheived is added to the amount of latching required to process your sorts. Forget about it.
The fact that V$SORT_USAGE is empty shows you that nobody is doing any sorts at the moment (it's a dynamic view).
ORA-03217: invalid option for alter of TEMPORARY TABLESPACE
This might happend becaue it's local managed ?Probably. Uniform tablespaces must have PCTINCREASE of zero (otherwise they ain't uniform).

Reasons to use separate temp tablespace for user tablespace

Hi,
I know that guideline says is not use system tablespace for user tables. But need i create for user tablespace separate TEMP teblespace or i can use same TEMP tablespace for all tablespaces?

Hi,
>>But need i create for user tablespace separate TEMP tablespace or i can use same TEMP tablespace for all tablespaces?
You can use one temp tablespace for a database , Temp tablespace usage are for sorting the data.
for more detail you can go with :Creating Tablespaces

How can I find out who is using all my UNTO tablespace?

The usage has grown from a usual 60% to 100% this morning, how can I find the culprit?
Thanks

Run the following query.
SET LINESIZE 200
COLUMN username FORMAT A15
SELECT s.username,
s.sid,
s.serial#,
t.used_ublk,
t.used_urec,
rs.segment_name,
r.rssize,
r.status
FROM v$transaction t,
v$session s,
v$rollstat r,
dba_rollback_segs rs
WHERE s.saddr = t.ses_addr
AND t.xidusn = r.usn
AND rs.segment_id = t.xidusn
ORDER BY t.used_ublk DESC;

Which temp tablespace will used during the import (impdp) ?

Oracle version : 11.2.0.3 on Solaris
We have created an empty schema called MLDT_FN and set its default temporary tablespace as TEMP_MLDT. We usually use SYSTEM user to do exports (expdp) and imports (impdp)
During a schema level (or table level) import to MLDT_FN schema, which temporary tablespace will be used ?
Will it be
the default temporary tablespace of SYSTEM user which runs this impdp job
or
the default temporary tablespace of the newly created MLDT_FN schema which is being to imported to

It will use default temp tablespace of schema.

--------------------------------------------------------------------------------------------------------------------Cant avoid the order by and distinct clauses. Cant avoid Outer joins. Indexes are used properly.

Just to add on to Mark's excellent points--
1) The Oracle optimizer is estimating that your query is only going to return 79 rows. If it is using a great deal of TEMP space, that estimate would seem to be wildly incorrect which implies that you have a problem with your statistics.
2) Are you certain that you need the DISTINCT? Lots of people either throw DISTINCT clauses into their queries "just in case" or throw in a distinct when they are unexpectedly getting duplicate rows because they are missing a join condition. If that's the case here, removing the DISTINCT and figuring out which join condition is missing (if applicable) would cause much less TEMP space to be used.

Temp tablespace 98% full

Hy
My temp tablespace (1 GB) is 98% full.
A.)How can I find out which user uses at a certain point of time in percent the tablespace.
B.)Does a full temp tablespace lead to performance problems reduces the "reply velocity" of a database

Lutz,
a) By using the following query you can determine who are all the users who have created their objects in TEMP tablespace..
SQL> SELECT OWNER, SEGMENT_NAME, SEGMENT_TYPE
from dba_segments
where tablespace_name like 'TEMP';
Once u get the names of the objects u can move to the tablespace u want.
b). According to me YES. Try to restart the database after moving the objects if any.. and this should give some space to u.
There is a bug in 8.1.6 related to the use of TEMP tablespace while using the sort operations.. Check it if u r using 8.1.6
Hope this helps,

CMS Repository Database Temp Tablespace Sizing

1. While running some large reports Business Objects (XI 3.1 FP2.7) received an ORA-01652 (Unable to extend temp segment in tablespace TEMP) error for the CMS repository. The CMS database is running in an independent Oracle instance with the auditing database, so only the Business Objects engine would be using the temp tablespace. All the report information is extracted from other database instances. This tablespace was sized at 4GB when this error occurred.
2. What is Business Objects using the CMS repository temp tablespace for? What are some sizing guidelines, should this tablespace be sized based on estimated report sizes, report rows, concurrent users, etc?

I'd say this has nothing to do with Webi processing and has everything to do with your Auditing DB.
Auding DB always growing and that's where that message comes.
Audit guide has more info on managing Audit DB.

TEMP tablespace increasing

I have a problem with storage space of my default temporary table space.
For my application, I specified the default table space as "DEFTBSPACE" with size 4000MB and temporary table space as "TEMP" with size 14486MB. Now, my usage of my temporary table space is increasing rapidly (Now, the used temp tablespace is 14485MB almost 99.99%). What could be the reason..? Is there any thing going into TEMP tablespace by mistake?.
Please help.
Reagrds,
Satish.

Can we deallocate manually the data file or a part of the datafile so that the usage space is reduced. What's the solution to reduce the usage space of this TEMP tablespace.If you bounce the db, you will get all used space.
I heared, dropping and recreating the TEMP tablespace is the only the solution for this..??Is it true?
Yes it is absolutely true.
Create another temp tabelspace and set as default temp tablespace and drop the previous one. However, make sure no one is currently using that temp tablespace.
The reason that you haven't get any result query v$sort_usge is that no one is using temp currently.
You can also use v$tempseg_usage.

CLOB processing consuming large memory in temp tablespace

We are having a stored procedure, which is called from a Java process to enqeue a message in to AQ. The input for the procedure is CLOB.
In some installations where oracle standard editions is used, the temp tablespace is growing in large volumes and the only process accessing the temp tablespace is the procedure. Oracle version is 9i 9.2.0.5.0
We are doing a trim on the clob variable inside the procedure. Will that cause any issues like this ?
Procedure is as below
procedure enq_msg
(queue_name varchar2, msg_text in clob,p_result out number) as
queue_options DBMS_AQ.ENQUEUE_OPTIONS_T;
message_properties DBMS_AQ.MESSAGE_PROPERTIES_T;
message_id RAW(16);
v_msg_text               clob default msg_text;
v_queue_name          varchar2(40) deafult queue_name;
BEGIN
v_msg_text := trim(v_msg_text);
v_queue_name := queue_name;
DBMS_AQ.ENQUEUE(queue_name => v_queue_name,
                         enqueue_options => queue_options,
                         message_properties => message_properties,
                         payload => v_msg_text,
                         msgid => message_id
     commit;
     p_result := 0;
exception
when no_data_found then
p_result := 1;
     rollback;
when others then
     rollback;
p_result := sqlcode;
END enq_msg;

Is there a reason you have v_msg_text and v_queue_name defined? You can use queue_name directly in the call to dbms_aq.enqueue and also payload => trim(msg_text)
This would eliminate the copying of the clob that is currently occurring and may help your space issue.
Is trim really needed?
I'm not familiar with any CLOB related bugs in 9i but the above is just some things I would try or question.

Users Temp Tablespace

I'm using Oracle 9i on Microsoft Windows Server 2003.
What is best practice when specifying a users temporary tablespace?
Is it safe to specify the TEMP tablespace that is present when you install Oracle? or is it better to create a seperate users temp table space?

TEMP tablespace that is present when you install OracleTEMP tablespace will be 40 MB in size with your default Oracle Installation!
CREATE
TEMPORARY TABLESPACE "" TEMPFILE
'C:\ORACLE\ORADATA\DB009\1.ora' SIZE 40M REUSE AUTOEXTEND
ON NEXT 640K MAXSIZE 32767M EXTENT MANAGEMENT LOCAL UNIFORM
SIZE 1024K
Check for the MaxSize and if it suits your DB - go on with it & it's safe using the Temp Tablespace!

Unusual Temp Tablespace Growth

Hi ,
We have noticed unsual temp tablespace growth when concurrent users are accessing OLAP cube through BI Bean crosstabs.
On an average 3 to 4 GB temp tablespace is consumed for each new user. OLAP cube has 7 dimensions and 1.2 million records and is fully precalculated.
This causes the system to fail as a result of temp tablespace getting full.
Can somebody please let me know what can be the root causes?.
Thanks in advance.
Harry

Hi there,
It is not unusual for OLAP queries to make significant use of temp tablespace. 3-4GB doesn't sound unreasonable to me. The actual amount used depends on factors such as the type of activity and the number of users.
There is a brief description of how OLAP uses temp tablespace here :- http://download.oracle.com/docs/cd/B28359_01/olap.111/b28124/admin.htm#sthref442
Note the lower than standard setting 'EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K' - if you are not already using this setting then you may find that it lowers temp space usage as the default setting is usually 1024K or even 4096K
I hope this helps

How to exclude UNDO and temp tablespace using monitoring template

hi,
as per MOS note id 816920.1 undo and temp tablespace is excluded from monitoring starting version 11G onwards.It says that thresholds will need to be explicitly set if undo and temp needs to be monitored
we have grid 12C implemented now with monitoring templates which sets thresholds for all tablespaces. does it apply that thresholds to undo and temp too?? we are receiving alerts for undo and temp tablespaces and we wish to disable them. We have undo tablespaces with different names in many databases as per naming conventions for that line of business.
How can i exclude undo and temp tablespaces from monitoring using grid 12C monitoring templates. is there a way through templates where i can set thresholds of permanent tablespaces only???

In EM12c, go to the 'Enterprise' menu, then 'Job', then 'Library'. There should be an out-of-the-box job called "DISABLE TABLESPACE USED (%) ALERTS FOR UNDO AND TEMP TABLESPACES" that you can run against your database targets, and that job will disable database-generated alerts.
If a previous admin has set up EM12c-generated alerts for undo and temp, then yes, a monitoring template will take care of disabling them. Either remove those alerts from the existing monitoring template and apply them to your targets, or create a new monitoring template based on one database's current settings, remove those warning/critical thresholds for your undo and temp tablespaces, and apply it to your targets.

Temp tablespace use

maintaining a cube via batch uses TEMP tablespace although the temp tablespace specified for the user is TEMP01. Olapsys has TEMP tablespace.
How to force it to use TEMP01?
Thanks.
pxsheth.

I don't have a good feeling for sizes of things (I'm a developer and don't typically see real-world data). Maybe someone else can give you stronger feedback. Also, you don't mention versions or anything. Sometimes that can be helpful.
The relational world and the OLAP world are different in a number of ways. The relational world doing OLAP-type stuff (data warehousing) uses materialized views for summaries.
Our stuff is closest in concept to that.
Remember that in OLAP, you create cubes. The (virtual) size of the cube is the product of the lengths of the dimensions. This number can go up fast with the number of dimensions. Most data is sparse (not all dimension values are meaningful). It is important to properly define your cubes to take that into account. Rdbms tables are automatically sparse (they only contain the rows that exist). Saying a table has 67,000 rows gives a sense of size, but no clue to the dimensionality and thus the size.
One GB of storage does not seem like a lot to me. You might get a hint at how much you need based on how far the build got. If it got most of the way, then its close. Otherwise you need a lot more. I might go up to 3-4 gig at a minimum, and consider doubling it a couple of times until you get a sense of how much you need. If you've gone back several times, and are only up to 1 gig, reconsider your size requests.
Can some of you active users help in the sizing area?

Oracle 9i TEMP tablespace backup problem using RMAN!

Oracle8/8i whole backup is ok for our backup software(using RMAN without RC database), but for Oracle 9i, I get following error messages when backing up temp tablespace.
1. RMAN-20202: tablespace not found in the recovery catalog
2. RMAN-06019: could not translate tablespace name "TEMP"
I check some views of Oracle9i, and know some changes happen for temp tablespace in 9i, but how to deal with this problem. Any idea, please!

In 9i RMAN does not restore temporary datafiles. Instead, you should create them after your restore. I believe that Oracle is going to make a change to this in the next release of 9i and have RMAN create the temporary files. You can view the temporary datafiles @ v$tempfile.
I believe RMAN doesn't restore temporary files because they are locally managed and not in the control files. RMAN reads the controlfile of the target database to obtain info about backups, datafiles, etc.
Hope this helps.
