Schedule A Process In Every Four Hours


I am supposed to schedule a process in Orchestrator which should run in every four hours on specific days in a week. Is there any way I can do that?



For this you have to use cron expression.

The format is

second, minute, hour, day, month, weekday

so the correct cron expression should be

0 0 */4 * * *

Hey thanks Lakshman. But can you please tell us how to define on specific days. Like we want to schedule it from the last friday of every month to the second monday of the respective next month.

Read the below article to know more about Cron Expressions.

Hi guys @lakshman

What I did?

  • 0 30 8,11,14,17 ? * MON-FRI Schedule A

  • 0 0 10,13,16,19 ? * MON-FRI Schedule B

Doing this I got my job running every 1 hour and half, from 8:30 untill 19:00, from Monday to Friday.
