running on multiple server instances about cron HOT 1 CLOSED

Hi kaiserlos,

thanks for using Cron. What should the Cron jobs do? Is it necessary that this jobs run on all server instances or can one server handle this?

If you choose your first option, the Cron jobs would be executed multiple because Cron has an overlapping protection but this works on file system basis. To prevent overlapping a database should be used for detecting the Cron run.

Your second option sounds good for me. The overlapping protection would not work either (because of the load balancing) but only one Cron will run on the same time. If your Cron jobs perform heavy load, the load balancing works great here and would choose the best server to execute the jobs. I would prefer this option.

If you have further questions don't hasitate to ask.

Many greetings
Marc
