Has anyone seen in SQL 2005 SP3 where agent jobs simply don't abide by a schedule setup? I had a bunch of jobs that needed to kickoff an hour longer so I scripted it.
UPDATE s SET active_end_time = active_end_time + 10000 --Add an hour
FROM msdb..sysschedules s
INNER JOIN msdb..sysjobschedules js ON js.schedule_id = s.schedule_id
INNER JOIN msdb..sysjobs j ON j.job_id = js.job_id
WHERE j.name LIKE 'This_Job_Needs_Another_Hour%' AND j.enabled = 1
I made sure a couple look right in the GUI scheduler. They run every 15 minutes and they're definitely not taking longer than that (which would prohibit the job from running on it's next interval). The SQL Agent logs are clear.
The best I can tell is that the agent service should be bounced.
