How Many Omnitrig is Enough

Jump to solution
I have a Unix based Omni server installed. By default, the omnitrig is run once from cron every 15 minutes. We only have schedule backup once a night. I would like to know if I can change the omnitrig cronjob to just one time only.

The following is configured automatically by omni:

0,15,30,45 * * * * /opt/omni/sbin/omnitrig

Thanks,

Steven

Yes, you can, reduce the number of omnitrig launches - but why? The overhead of a small cron task every 15 minutes is trivial. Moreover, if you do change your backup schedule, you then must remember to make a crontab change. You must also remember to leave in the times that your database purges occur. The GUI scheduling interface is built around the assumption of a check every 15 minutes.


If you insist upon doing it this way, it makes much more sense to dispense with omnitrig altogether and start all your OB2 tasks directly with cron.
If it ain't broke, I can fix that.
