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 This is an example of how the site you linked to often contains lots bad or outdated information.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 17.3k32562 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 a

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.
