PL/SQL :: Temp Tablespace Space Due To GTT Table
Sep 3, 2012
We are using a GTT table to store the summarize data and display it on same screen(10g 10.2.0.5). Now we are facing temporary tablespace space issue very frequently as our client do not enable the auto extend on for temp table space. We have analyzed the AWR and came to know that there are 900000 inserts per hour on an average. Client DBA Claims that there are sessions(1or 2) which inserts the data in temporary table continuously for 2-3 days.
According to him one session is running from 28th Aug and problem comes on 2nd Sep and after killing the problematic session the application will work fine. Generally this problems come on weekend. I have discussed with our dev team and as per them there is no session leakage issue.
following is the insert statement:
INSERT INTO DT_CA_STNDALN_DETAILS_TMP (ORG_ID,BA_PRODTYPE_ID,MAX
TENOR,GROSSLIMIT,GROSS_UTILISATION,HAS_MDR,HAS_CLUSTER,SIGN_IN
D,GROSS_AVAILABILITY,COLLATERAL,NET_UTILISATION,DT_CA_STNDALN_DE
TAILS_TMP_VER,DM_LSTUPDDT,NET_AVAILABILITY) VALUES (:1,:2,:3,:4,
:5,:6,:7,:8,:9,:10,:11,:12,sysdate,:13) ;

I am getting temp tablespace error "ORA-01652: unable to extend temp segment by 128 in tablespace TEMP" for the following code.
SELECT /*+ USE_NL ( vd1 ,vd2 ,vd3 ) leading ( vd1 ,vd2 ,vd3 , tvd) */ vd1.vendor_record_seq_no,
tvr.checksum, tvr.rownumber, tvr.transaction_type, 'U'
FROM vendor_data vd1, vendor_data vd2, vendor_data vd3,
(SELECT rownumber, MAX (DECODE (control_column_seq_no, 91150, original_value, NULL)) AS value1,
[code]...
Right now used tables has the following number of records-
SELECT COUNT(*) FROM vendor_data --292890442
SELECT COUNT(*) FROM temp_vendor_data --0
SELECT COUNT(*) FROM temp_vendor_record --0
This query is part of an application, but consuming too much of temporary tablespace (68 GB allocated). I found it out by using query below:
select * from v$session a, v$sql b
where a.sql_id=b.sql_id
and status = 'ACTIVE'
I am not sure, why this problem is occuring.

One of our customer have problem with following sql statement:
SELECT c.table_name, c.column_name
FROM user_tab_columns c, user_tables t
WHERE c.table_name = t.table_name
AND c.data_type IN ('CLOB', 'BLOB');
During execution it takes all the TEMP tablespace size(8GB).
I gather system stats (dbms_stats.gather_dictionary_stats(estimate_percent=>null)) but it doesn't resolve problem.Above sql statement works fine with RULE hint but I want to know what is the reason of problem with temporary tablespace.

I am trying to run on Oracle report via Oracle Application Concurrent job. Concurrent job is completing normal but I don't get anything on print out page. In log file of this request I see message 'MSG-01003: Errors =>ORA-01652: unable to extend temp segment by 128 in tablespace TEMP'. I almost doubled the TEMP tablespace in size but still I am not able to get rid of this error message.

this huge report that uses inline views. I keep getting the following error message when running the script through toad. I was thinking about using the USE_HASH hints. The sql optimizer we use is very buggy in Toad. I'm using oracle database version 10.2.0.3.
I can upload explain plan if needed.

How to check for the increment of a space of the tablespace based on the particular table. (i.e.) Say a scenario, if am trying to load the data for a particular table, for first I loaded some 10000 records and then again loading 50000 records ,so based on the icrement of the reocrds the tablespace size also increases gradually . so for this scenario how to monitor the increment of the space.

how to check the maximum space ever used for TEMP. I want to know it because I need to resize the TEMP and I want to know how small it can be. As I can see from a documentation hURL....max_size is max number of extens ever used in a segment
I could multiply max_size by extent_size and it would give me the max size of temp ever used
SQL> select segment_file, extent_size, max_size from v$sort_segment;
SEGMENT_FILE EXTENT_SIZE MAX_SIZE
0 128 23625
0 128 753

I run a query, takes 20 minutes or so, I traced it and can see no more then 20-30 mb of temp space required in the plan.
I developed it for use in a materialized view, however when I create the mview with the sql, the temp space required grows until it maxxes out. I increased the existing 10gb to 50gb but still maxxed out. Took the SQL out, reran it, ran in 20 minutes barely scratching the temp, I ran a "create table as <select>" and same behaviour as the SQL, barely touched the temp as per the plan. So the temp space blolwing is unique to the mview create.
Im working with mviews years on several sites and have never seen this.

If the temp space left is 0%, i.e. all temp space used up, is it possible to make new DB connection ( can new users still connect to the DB)?
Or re-phrasing the question... How much of temp space (if at all ) is required for a new user to login to DB? Like SORT_AREA_SIZE in PGA. So, as memory sort area is already used ( Temp space is 100% full), can DB make more new connections?

I tried to create an index on a large volume table(approx 9 GB) and I got the below error message:-
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
The size of our TEMP tablespace is 3GB and currently it is showing as full.
This tablespace is locally managed and we are not running any other operation on this test database at the moment.
We need to delete data from this table based on a column value, so I was planning to create an index on that column.
I saw on the net that one of the proposed solution is :-
alter tablespace TEMP default storage (pctincrease 1);
alter tablespace TEMP default storage (pctincrease 0);
alter tablespace TEMP coalesce;
but it was mentioned that this does not work with Locally Managed Tablespaces.
We are currently using Oracle 9.2.0.7.0 production release installed on Linux platform(Linux 2.6.9-89.0.25.ELsmp #1 SMP i686 i686 i386 GNU/Linux)
I increased the size of TEMP tablespace to 12 GB but the index creation still failed with the same error.

We all know that Temp segments in Temporary tablespace don't deallocate even after the process completes, the extents are only marked for reuse.
After an instance restart, it should de-allocate, or what is the default behavior?
Doesn't SMON de-allocate temporary segments here during instance startup?
If it doesn't de-allocate space then it will run out of space, the next time a huge sort operation takes place.
So my next question is how to estimate the correct space of the temp tablespace in the physical design phase.?

on my 11.2 DB comes from time to time to situation that the temp tablespace runs full. It longs for only couple of seconds and when the dba notice it, the tablespace is already almost empty. Is it a way somehow to create like a "callback-notifier" that fires f.e. when temp tablespace is for let's say 70% full. That "callback-notifier" will run the sql-statement to look in v$session, v$sort_usage, v$process, v$parameter for the problem sessions.

We have a database running with Oracle 10.2.0.4 on Solaris 5.10 [SUN SPARC v240] where the assigned TEMP tablespace size looks to be quite huge ( = 8GB!). There are not much SQL queries being run on the database, but what can I do/find/investigate to be sure of how much TEMP space is 'actually' required for the application to run OK?
Note. I have seen the previous DBA's have marked AUTOEXTEND = ON for the TEMP datafiles as well.
Separate query (but linked to TEMP tablespace):
Even if the TEMP datafiles are created with AUTOEXTEND = ON, sometimes I am seeing 'ORA-01652: unable to extend temp segment by 128'.

I have tried to add relevent join conditions in where clause but does not work. Moreover, the space has too been increased by DBA but does not work.
The added two tables are RCV_TRANSACTIONS and RCV_SHIPMENT.

I have two tables with huge data with them. I want to compare both the tables (row by row comparison). So I have fired a query like the following:
SELECT * FROM TAB1
MINUS
SELECT * FROM TAB1@DBLINK;
SELECT * FROM TAB1@DBLINK;
MINUS
SELECT * FROM TAB1;
But the tables are having very huge data (25 Crores). So I am getting the following error after a long time:
ORA-01652: unable to extend temp segment by 512 in tablespace TEMP1
Is there any other way to compare these tables (row by row)?

the temp usage was as follows
Tablespace name Total MB UsedMB FreeMB
TEMP 128818 100735 28083
Only 100GB was used and there was about 28GB free space in Temp.But still i was getting the error.Was it becos it was defragmented and was not able to find a contigous segment? Is it applicable for temp tablespace also..
