Oracle Alert - ORA-1652 Unable to extend the Temp Segment
Hi Team,
During our DB Reorg we have received the Oracle Alert - ORA-1652 Unable to extend the Temp Segment by 15485 in tablespace :PSAPBTABI.
Our DBReorg got cancelled..
We would like to know how we can resolve the above error so that we can reschedule the DB Reorg activity..

Hi,
If you are using UNIX OS, the temp files are created as sparse file due to the OS functionality.
Altough you have assigned 49 GB the actual size will be very very less.
You can check the actula file size with du or df command. To remove these sparse condition you will need to perform certain steps.
Read this note and execute the steps given and then see the file size difference.
548221 - Temporary Files are created as sparse files
Do update the message if the OS is different.

Unable to extend the temp segment by 2560 in table space TEMP
Hi,
I am running the procedure, it aggregate the data, it's taking minimum 1 hour to complete. B4 complete it throw an error:
ORA-01652 - Unable to extend the temp segment by 2560 in table space TEMP.
Note: Tround 5GB disk space is there.
Please help and give me your suggestions.
Thanks
SathyaWell, I'll go out on a limb and suggest that the problem is that the procedure ran out of TEMP space. It's relatively easy to generate 5 GB of intermediate results to sort in the space of an hour. If other sessions were using TEMP space at the same time, that would obviously reduce the amount available to this procedure.
Your two options would be to decrease the amount of sorting that the procedure needs to do or to allocate more TEMP space for it.

Regards,
balaramHI,
ORA-01652: This error is caused by a tablespace overflow. As a rule of thumb, PSAPTEMP should be at least twice as large as the largest index. If an overflow occurs despite this size, this is frequently due to external reasons such as incorrect Oracle parameter settings, large-scale parallel processing or unfavorable access paths. See also Note 3155.

ORA-1652: unable to extend temp segment
Hi,
I am new here and i am not sure if my question is for that section but will be happy to get some answers.
I found ORA-1652: unable to extend temp segment by 128 in tablespace PSAPTEMP in alert log and checked the space in PSAPTEMP.
TABLESPACE_NAME MB_FREE FRAGMENTS BIGGEST_BIT
PSAPTEMP 0.00 1 0.00
Could you advice me what to do?
Thanks in advance
MikiMiki, you probably need to add space via adding another data file as the posted error message information says or you might first look to see what is using the space to make sure someone did not do something 'stupid'. In this case stupid would be assigning the wrong usernames the affected tablespace as their default temporary tablespace when the users should be assigned a different one or some other misconfiguration.
Most likely you just need a larger tablespace, but it never hurts to know why or how much larger before taking action.

Hi All,
Today in we have faced the below issue in our production database
ORA-1652: unable to extend temp segment by 128 in tablespace TEMP
ORA-1652: unable to extend temp segment by 128 in tablespace TEMP
when we checked we are having 99% of free space in temp tablespace,we are not able to understand why we got this error.
earlier also we got the same issue adding datafile to the tablespace solved the issue. wanted to know if free space exsists why we getting this error.

best regardsHi,
We had the same error in our Production system.
That basically occured when there were a lot of Background jobs that were running.
As more than 5 jobs were running which were utisiling PSAPTEMP to the fullest invariably the jobs got cancelled with a dump and the error u have mentioned
Though we tried adding 3 datafiles the error kept repeating..
We finally added almost 20 GB to PSAPTEMP for those jobs to get completed. -

TEMP--------0--------0-------------0Unless you are running the query against v$sort_segment at the point in time that you are getting the errors, I would strongly suspect that something tried to use more than 16 GB of TEMP space, the query died, and when you subsequently looked, nothing was attempting to use much TEMP space. That doesn't mean that some process wasn't eating up all your TEMP space earlier.
My guess (no evidence, just a hunch) is that you have a query that is doing a Cartesian join, that query rapidly consumed all the space in the TEMP1 and TEMP2 tablespaces, encountered this error before exiting and freeing all the TEMP1 and TEMP2 space it had acquired before you ran your query.

ORA-1652: unable to extend temp segment by 187502
Hi ,
OS=AIX 5.2
DB= Oracle8i , 8.1.7.4.0.
I've seen few ORA-1652 in alert log file, and the TS that it shows with error is permanant and dictionary managed Tablespace as there is no temporary tablespace in the database, its autoextend is off.
This Tablespace is of total 13 GB , with 2 datafiles (9G + 4 G). one datafile is almost 30 % Free the other is 80 % free. that shows that there is enough free space in the tablespace and on the filesystem there is also enough freespace.
initital extent and next extent are 1 Mb with pct increase 10.
If somebody can help to solve out this issue, and why this error occured.
Thanks in advance!Are you sure the user runing the large sort is using the right temp-tablespace?
If not then he uses the system tablespace for temp, and that might be something you should not want.
And if i am correct Oracle does not clean out the temp-tablespace in ways of showing the free space it actualy has. At least in Oracle 9 this is the case, the temp tablespace will show a used percentage of what it ever was used and not how much actualy is being used. It can be free actualy, but showing a 100% used in the tablespace-list (in the oracle enterprise manager).
This makes me feel that if you say the temp-tablespace still has unused space, the query does not use the right temp-tablespace. -
Ora-1652 : unable to extend temp segment by 8 in abc tablespace
Hi
When this error shoots up , we can add the datafile to the tablespace or make the datafile autoextend on.
There is no space left on the hard drive how can we gain free space in the tablespace so that normal inserts on the table is not interrupted.
I had tried using : Alter table tname deallocate unused; with no result.
ThanksIn Oracle 10g you can :-
alter table xxx shrink space cascade; -- this will reclaim any empty space in tables and index. This can lock the table, so be careful when you run it.
Alter table xxx compress; -- this will compress the table data so it takes less space. This can potentially cause performance problems, so make sure you understand it before you implement.
I don't think these options will help you though. I think the problem is that your temp segments are in the wrong tablespace, or the select statements are badly tuned and are using too much temp space.
