Ora-12801: Error Signaled In Parallel Query Server P003
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 the server is especially active, and it's always the second message (in your case, ORA-01652). MOSC note 184416.1 has ora-12801: error signaled in parallel query server pz99 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 tablespace, or better still, increase your sort_area_size. If this job is running batch, you can do this with an alter session command, as this this case, to one gig: alter session set sort_area_size = 1,048,576,000 If you like Oracle tuning, see the book "Ora

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 This is an example of how the site you linked to often contains lots bad or outdated information.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 fir
