dbms_schedulers delays
So we are having an intermittent problem, we have a job that is scheduled thru dbms_scheduler to start at 10:00PM Sun - Fri. Occasionally, it doesn't start for several hours, in the particular run that I am looking at, 5:21:25am. Usually it starts on time. There are no run dependencies on this job. Here are the specific details of the job execution:
Log ID 382707
Log Date Mar 29, 2018 9:16:20 PM -06:00
Request Start Date Mar 29, 2018 10:00:00 PM -06:00
Actual Start Date Mar 30, 2018 5:21:25 AM -06:00
Run Duration -485.08
So, How can I have a negative duration of -485.08? Why is the start date 7:21 hours later than the requested start date?
