Ora-12801: Error Signaled In Parallel Query Server P008
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 the server is especially active, and it's ora 12801 error signaled in parallel query server p007 always the second message (in your case, ORA-01652).

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.

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 This is an example of how the site you linked to often contains lots bad or outdated information.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