ora-12801 ora-01722 Parallel query error ORA-12801 Oracle Database Tips by Burleson Consulting Question: ora-12801 error signaled in parallel query server p003 instance When running Oracle parallel query, I get a sporadic error like this: ERROR: ORACLE execute error: ORA-12801: error signaled in parallel query server P017 ORA-01652: unable to extend temp ora-12801: error signaled in parallel query server pz99 segment by 314 in tablespace TEMP. I understand the ORA-01652 as being caused by running out of space, but I do not understand the ORA-12801. Answer: Wow, P017, that's a lot of parallel query processes. Just make sure that you have enough processors to support this load. I've seen this ORA-12801 error pop-up intermittently for no apparent reason, usuallyOra-12801 Ora-01652
when the server is especially active, and it's always the second message (in your case, ORA-01652). MOSC note 184416.1 has details on diagnosing the ORA-12801 error. It notes that the ORA-12801 is somewhat generic and that you should look for more details in your alert.log or in trace files in the USER_DUMP_DEST or BACKGROUND_DUMP_DEST location. You can set event 10397 to get more details: ORA-12801, 00000, "error signaled in parallel query server %s" Cause: A parallel query server reached an exception condition. Action: Check the following error message for the cause, and consult your error manual for the appropriate action. *Comment: This error can be turned off with event 10397, in which case the server's actual error is signaled instead. In any case, the central question is why your parallel query was performing a sort, resulting in the ORA-01652 error? OPQ generally sorts as the final step, after the paralel processes have returned the result set to the parallel query coordinator (usually P00).The symptom solution, of course, is to increase the size of your TEMP tablespa

Re: ORA-12801: error signaled in parallel query server P081 sybrand_b Jun 11, 2012 9:57 PM (in response to 735967) lot_no is a varchar2 column and Oracle translates your query to select * from v_putaway where to_number(lot_no)=91245 and flag_selected=0 It fails as you have data problems. Solution: cleans your data, and after cleansing correct the datatype. ------------- Sybrand Bakker Senior Oracle DBA Like Show 0 Likes(0) Actions 2.

The script was executed by user and I can see 1 user in error signaled in OS but see 4 oracle users running the program each as p000,p001,p002,p003. can anyone give little input why I can see 4 oracle users. Is that because the queries running in parallel ?? But if it is a script does not it execute one after the other. User got a error later ORA - 12801 error signalled in parallel query server p003. ORA-01652 unable to extend temp segment by 1024 in tablepsace temp. The temp tablespace is 8G. This is happening because of the process running in parallel. where is the problem occuring? is that because of parallel queries. what is ultimate solution.

You (probably) need more TEMP when operating with PQ. If you are not specifying your degree with a hint, you might look at the tables involved. They probably have a degree > 0. To turn PQ off, you can override the default degree with +PARA
