Hi Niall, was just trying that in one of our test databases: SQL> show parameter job_queue_processes; NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ job_queue_processes integer 10 SQL> exec dbms_scheduler.set_scheduler_attribute('SCHEDULER_DISABLED','TRUE'); PL/SQL procedure successfully completed. SQL> show parameter job_queue_processes; NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ job_queue_processes integer 10 At least disabling the scheduler that way did not modify the parameter. Did you possibly do it another way?
