Maximum TEMP Space Ever Used
Oct 2, 2012
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

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.

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?

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.

I'm currently doing migration from Oracle 10gR2 RDF to Oracle 11gR2 Semantic Technology.I followed the steps on the documentation and successfully created the network using the following:
-----
EXECUTE SEM_APIS.CREATE_SEM_NETWORK('rdf_tblspace');
CREATE TABLE rdf_network_trace (id NUMBER, triple SDO_RDF_TRIPLE_S);
--Created SEQUENCE andTRIGGER FOR rdf_network_trace id
[code]....
when I looked at my Node Ids, they were like +635762253807433724+, +6118969225776891730+. The problem is, I am not the one who is assigning Node Ids, They were automatically generated when inserting TRIPLE data to the rdf table.
Did I miss something when I created my network?

Just now sysaux resized to 600m from 250m >>
Sysaux Tablespace is running low. WE SET AWR RETENTION TIME=60 DAYS. WE ARE NOT INTEREST TO EXTEND SYSAUX TABLESPACE SIZE.
Usually we take AWR weekly once. Some times we did ADDM report and ASH.
CODEsql>select TABLESPACE_NAME, FILE_NAME, BYTES/(1024*1024), AUTOEXTENSIBLE, MAXBYTES/(1024*1024) from dba_data_files where tablespace_name = 'SYSAUX';

1. What's the best SOLUTION ?
2. Can i shrink sysaux tablespace ?
3. I think , The size for all occupants in sysaux tablespace is less than 200 MB => how to find actual content of sysaux tablespace ?
4. What could be the reason for growth? Is there any way to free the space from sysaux table space?

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.?

I'm having some issues with my NVarchar2 columns that I want to solve
My current NLS_CHARACTERSET is 'AL16UTF16', and therefore I can only create NVarchar2 columns with an maximum extension of 2000 bytes. But I do need a column with 4000 bytes length. How can I create an 4000 NVarchar2 column?
(I do not want to use a CLOB column...only a NVarchar2)

I am building a reporting table using the count analytic function in order to count up several different attributes in one statement.What I find is that this method quickly eats up my TEMP space. This is 10gR2. I have attempted to use MANUAL workarea policy with as large ofsort_area_size as possible (2G) but that does not seem to have any effect on performance or TEMP usage. The RAW table is about 12G with 75 million rows. I am not that concerned about execution time, but rather TEMP usage.
--INSERT into <object>...
select distinct
file_sid,filename,control_numb,processing_date,file_class,
vendor_id,vendor_desc,
c_status_id,c_status_desc,
[code]...
I am not seeing any increase in onepass or multipass executions on the PGA during execution of this statement using...
SELECT CASE WHEN low_optimal_size < 1024*1024
THEN to_char(low_optimal_size/1024,'999999') ||
'kb <= PGA < ' ||
(high_optimal_size+1)/1024|| 'kb'
ELSE to_char(low_optimal_size/1024/1024,'999999') ||
[code]...
I'd like to get a better explaination of how analytics use the instance resources and TEMP space. For example if I add
a count with a different window (such as the last two columns commented in the above query) I blow out my temp space (70G).
Is the critcal factor the use of distinct? or multiple windows? or something else?
