How to disable the DBMS_SCHEDULER

I discovered this after searching all over the web and am putting it here so that I do not have to do that again.

To turn the scheduler off use

exec dbms_scheduler.set_scheduler_attribute('SCHEDULER_DISABLED', 'TRUE')

Note that the TRUE is not a BOOLEAN but text.

To check the status

select * from DBA_SCHEDULER_GLOBAL_ATTRIBUTE;

To turn the scheduler back on again

exec dbms_scheduler.set_scheduler_attribute('SCHEDULER_DISABLED', 'FALSE')
