Replication job starting out of schedule

Post by arondan » Jul 09, 2019 6:21 pm

Hi guys. This one is really baffling me (but that is not so hard though :lol: )

Here is the scenario:

We have 7 replication jobs that should run starting at 08:00 AM every 3 hours until 05:00 PM. The way we configured this is:

Job 1 - Runs every 3 hours (limited by schedule from 08:00 am to 05:00 pm)
Following jobs are configured to run "After this job:" (Job 2 runs after 1, Job 3 runs after 2 and so on)

All the jobs take to complete between hour and half or two hours.

Here is the problem:

Every day job 1 starts running at 8:00 am and then all the jobs continue to run ok. But at 9:00 am Job 1 starts running again. This eventually sets in motion all the replications again. Considering that when Job 1 starts, there are still running jobs from the previous 8:00 am trigger. We have overlapping of replications which often create issues and errors.

I tried to pull settings with the console (maybe the GUI was buggy) but as far as I can understand nothing should set this job to run at 9:00 am

Code: Select all

Am i missing something? I checked logs for the Job too, nothing too obvious.

What you see is expected behaviour, as periodic interval are counted from midnight: 00-00 + 3-00 + 3-00 + 3-00 = 09-00. Backup window doesn't affect this anyhow, it just prohibits job execution at certain times.

Also, be aware that job chaining is not considered the best practice.

Thanks!

Thanks! Ok I see what you mean, and from that perpective. It totally makes sense. Now I wonder then, why the Job starts at 08:00 am?

It tries to catch up with the missed attempt (the one from 6 am). Thanks!
