Parallel query error ORA-12801 Oracle tips by Burleson Question: When running ora-12801 error signaled in parallel query server p002 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 segment
Ora 12801 Error Signaled In Parallel Query Server P000
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, usually when ora-12801 ora-01722 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 table

The system tried to execute the query in parallel. So the query was split in many parts. Each part connects to the database and will be executed. If there is no free connection this error occurs. Retry it if there is less load on the database or allow more simultaneous connections to DB.Regards,Juergen Alert Moderator Like (0) Re: Database error text........: "ORA-12801: error signaled in parallel query A S Nov 1, 2007 8:16 PM (in response to subhash gadde) Currently Being Moderated During what action do you get the short dump ?What system and patch level are you on ?Check sap notes 747225, 634458.

Action: Check the following error message for the cause, and consult your error manual for the appropriate action. This is a generic error message and almost never has anything to do with not enough processors. This is an example of how the site you linked to often contains lots bad or outdated information. Maybe 17 processes was "a lot" 17 years ago, but it's not today. Unfortunately, that site is often the first result from Google. You can check the UNDO retention, which is the amount of time in seconds, like this: select value from v$parameter where name = 'undo_retention' Once again, see the manual for more information on the parameter. share|improve this answer answered Apr 11 '15 at 21:08 Jon Heller 17.2k32461 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By p
