View 1 RepliesOne 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 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.
If my tablespace goes beyond 80% I should get a email from Unix crontab.
1)Warning for tablespace 80% full.
2)critical for tablespace 90%full..
I need the script for Oracle tablespace with 87% and shell script.
Do I need 2 scripts? Is there anything ready available (Oracle 10g).
we have a situation where both undo tablespaces were almost filled i.e UNDOTBS1 99% and UNDOTBS2 100% filled so i add data files to it and then i found a lot of blocking session and was just killing them through EM then i stop my front end listener and also down the service, now i don't have any blocking session but on EM a big WAIT is coming. alert log shows nothing serious, it was showing deadlock but now it is over as well.

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.
most of the time i am seeing temporary tablespace issues like temp tablespace is 100% full.
do we have any procedure to clean up temporary data from tablespaces.
and does it effects to database anything.
share any link
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.

Is there any way to check this history data, what other session was using TEMP tablespace extensively ?
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.
The below query is utilizing more than 17 Gb temp space. But still it is getting failed out due to insufficient temp space. is there any way to rewrite this query to reduce the temp utilization?

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 am using 11.2.0.3.0 version of oracle. We are planning to move some ~40 tables/indexes to new encrypted tablespace as a part of TDE(transparent data encryption). Currently three tables are having size ~30GB and one having ~800GB other have <2GB in size. And tables/indexes are altogether placed in different tablespaces.
whether i should create as many no of encrypted table spaces as it was before as unencrypted tablespace? or I should create one encrypted tablespace and move all the tables/indexes into that?
I am receiving this error in production databases...There are 2 probable extent failures for tablespace
View 14 Replies View RelatedAll the analysis till now on our system proves that our system is clearly I/O bound and db sequential read is the biggest culprit.
We have even identified the index which is being affected by sequential read. I am thinking of creating a new tablespace with 32K blocksize (currently all table spaces are 8k) and migrate this index to the new space. That way, Oracle will have to do less number of reads to get the required data.
But is there anything wrong in having just one tablespace with a differnt block size? Or is there anything that I have to be watchful about while doing it?
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.?

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:

i got a error temp tablespace cannot be resized. How to Resize Temp Tablespace?
View 10 Replies View RelatedWe 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 get the error while adding two tables and joining with the other tables.
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 am getting error "ORA-1652: unable to extend temp segment by 128 in tablespace" but i can see there is enough free space left in TEMP. I can see we have many active session. how can we drill down to solve this error. Below is the status for all the tablespaces.

Is there any other way to compare these tables (row by row)?
