Help!

I have a job called 'EnableJobs' scheduled to run every night at midnight. EnableJobs looks like this:

JobEnable("Adjusted Price File", TRUE)
JobEnable("Asia Price File", TRUE)
JobEnable("Europe Price File", TRUE)
JobEnable("NA Price File", TRUE)
JobEnable("Regular Price File", TRUE)
JobEnable("Interday Adjusted Price File", TRUE)

That's it. These 6 other jobs (all in the same queue) may or may not be disabled when this runs. However, 24x7's queue monitor shows EnableJobs as running, even though it doesn't actually ever complete or even perform any of its tasks. All other jobs then stack up behind it waiting for this hanging process to complete.

I can 'Run Now' EnableJobs successfully every time. I checked the files in the Performance Data and Queue directory, but nothing looks odd (I'm not sure what I'm looking for there)

I have jobs running at midnight in another queue -- perhaps those are interfering somehow?

Help!
Thanks,
Steve

If you make this job asynchronous it will not block the queue even if it hangs.

Just out of my curiosity when and how do you disable jobs?

Date specific files are created on the system asynchronously, so I have 6 different jobs that wait for these 6 files. When found, these jobs process the files. Since I don't want the jobs to run again after processing the files, I disable them until midnight when they are re-enabled and wait for the next day's files.

I have 2 different jobs from different queues both scheduled for exactly midnight. Could this be a problem?
Thanks,
Steve

This might be a problem, because the job that enables 6 other jobs forces the active job pool to be flushed and then reloaded. This can create some kind of a conflict with the other midnight job.

Can you schedule one of those jobs to start 1 minute after midnight to see if that will fix the problem?

Yes!! That worked! It seems like the conflicting job should just be delayed, but this works, so I'm happy.
Thanks,
Steve
