ORA-1650: unable to extend rollback segment
Hi,
We have 20 RBS's and in our production instance we got very frequent alerts related to ORA-1650: unable to extend rollback segment continuously. When I looked for select STATUS from v$rollstat; I could see most of them are with FULL status. after couple of hours they disappeared and status became online.
How to avoid these type of alerts?

What version of Oracle?
If you are 9ir2 or later, you should be going to automatic undo management. Though it won't help your 'we cannot add space' restriction. That's not an Oracle problem, that's a corporate issue.
This problem may be caused by poor transaction design with too many processing doing too infrequent commits. That's not an Oracle problem either, that's a corporate/development issue.
So...you don't have an Oracle problem.
You can't stop the 1650s from occurring if you are unwilling to add space or address application issues. However, you can set up an email filter so that any emails containing ORA-01650 in the header or body get automatically sent to the trash.
<sarcasm>
If you can't solve a problem, then just ignore it!

DAL Exception: ORA-01562: failed to extend rollback segment number 4
Hi,
in our application log, we got sometimes an error ORA-01562: failed to extend rollback segment number 4 and the application hangs and some transactions are blocked. checking the aler database file, we don't found this error but it's appearing often in our system.
would you lease advise what to do to avaoid this error, or is there a script to find oracle SQl where using too much rollback segment.
My configuration is : Oracle 10g r2 in linux SUSE.
thank you

The Sky is Falling! ORA-01652: unable to extend temp segment by 128
So we currently have a production problem and I'm not so in the know as a lowly java developer and not an Oracle expert.
We keep getting this error(below) when a certain heavy query hits the DB.
Our DBA claims that the tablespace for 'TABLE_SPACE_NAME_HERE' is 20GB of space and that the problem is the query.
The query has been running fine for many many months but all of a sudden is presenting a problem and we have to do something quick.
We tried bouncing the application server but the error came right back when the big select query gets hit.
Any thoughts? Help! : )

So, the next question... what is our lesson learned in this case?It depends on the root cause.
Our DBA thinks 30GB is an unreasonable size for the tablespace and is fingering the select query that was causing the error to occur. Their solution is move to the query to a view and then reduce the tablespace back to 20GB.
My thoughts are shouldn't the DB be able to handle a query that has been running fine for the last couple years? Also, if we do what is suggested what would prevent another query from coming along and causing the same issue all over again?Has the DBA identified the source of the issue? Did the query plan change? It's possible that something with statistics (or with some configuration change) causes Oracle to believe that two different query plans are roughly equally efficient. One plan might take substantially more TEMP space than another. It's possible that Oracle had been choosing the plan that involved less TEMP space being used and recently changed to preferring the plan that takes more TEMP space. If that's the issue, you may want to force Oracle to use the plan that involves less TEMP usage.
Regardless of your TEMP tablespace size, another query may come along that causes TEMP to run out of space. Or data growth may cause TEMP to run out of space. Or an increase in the number of users may cause TEMP to run out of space. Ideally, the DBAs would be identifying how much TEMP space is used over the course of the day so that if things are growing steadily additional space can be added as necessary. If TEMP space increases dramatically because a query plan changes, however, even the best monitoring is unlikely to be able to predict that level of growth.
Whether 30 GB is unreasonable (or whether 20 GB is unreasonable) will depend heavily on your application. We don't know enough to be able to comment. A TB-sized OLTP database serving millions of customers will have very different TEMP requirements than a multi-TB data warehouse which will have very different TEMP requirements than a small department-level application.
My surmising is we must have just crossed a watermark threshold and the simplest most reasonable solution is to just leave the larger tablespace size.Why do you believe this is the case? It is entirely possible that you need more TEMP because your TEMP usage has been growing slowly over time. It is entirely possible that the query in question has always been using more TEMP space than it really should and that you finally have enough usage to cause the problem to bubble to the surface. It is entirely possible that the query used a reasonable amount of TEMP for the past couple years and suddenly started using far more because of a query plan change. Once you identify the source of the problem, we can figure out the appropriate solution. Without knowing the source of the problem, we're all just guessing.

ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
Hi,
I am getting the following error while executing an insert query.
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP.
I have tried increasing the TEMP tbsp size it got resolved temporarily but occurred again after few days.
When the problem occured, following query shows all insert queries in TEMP tablespace and one of them consumes about 5GB and others are about 24MB.
SELECT S.sid || ',' || S.serial# sid_serial, S.username,
T.blocks * TBS.block_size / 1024 / 1024 mb_used, T.tablespace,
T.sqladdr address, Q.hash_value, Q.sql_text
FROM v$sort_usage T, v$session S, v$sqlarea Q, dba_tablespaces TBS
WHERE T.session_addr = S.saddr
AND T.sqladdr = Q.address (+)
AND T.tablespace = TBS.tablespace_name
ORDER BY S.sid;
The insert query is :
INSERT INTO SEOSDATA (ENTRYID,DOMAINNAME,USERNAME,EVENTTYPE,LOGNAME,TIMSTAMP,SOURCE,COMPUTERNAME,EVENTID,EVENTCATEGORY,SEARCHSTRINGS,MSGTEXT) VALUES (ENTRYID_SEQ.NEXTVAL,:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11)
It is not expected that an insert query consumes such a huge memory.
Can someone help me in figuring out what the problem is.
What might have gone wrong? Seems like sorting is used, why an insert query uses sorting?
Regards
IshuHi,
Insert statement should not use TEMP tablespace. Please check with following query which user and session id is using TEMP tablespace.
SELECT b.tablespace, b.segfile#, b.segblk#, b.blocks, a.sid, a.serial#,
a.username, a.osuser, a.status
FROM v$session a,v$sort_usage b
WHERE a.saddr = b.session_addr
ORDER BY b.tablespace, b.segfile#, b.segblk#, b.blocks;

how to retify it.what is the command to add datafile or tablespace......

Thanks in advancecreate tablespace or add index, that you can find out at http://tahiti.oracle.com
You should check space on CDR_TAB.
I think you can create new tablespace

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.

ALTER TABLESPACE

why add datafile in user tablespace¿?
and you solved the issue doing the same like we told you a few days before in:
