Cron does not support minute-based intervals that are not divisors of 60, such as every 40 minutes. Fixed-rate scheduling lets you define jobs that run at regular, non-standard intervals with a simple expression, though it does not support second-level precision.
Configure fixed-rate scheduling
You can configure fixed-rate scheduling when you create a job. For more information about creating a job, see Create a job. This topic covers only the fixed-rate scheduling configuration.
-
Go to the Timing configuration step. For more information, see Create a job.
-
In the Timing configuration step of the Add Task wizard, set the scheduling parameters, then click Next.
-
From the Time type drop-down list, select fixed_rate.
-
In the Fixed frequency field, enter the execution interval in seconds.
NoteThe fixed frequency must be at least 10 seconds. For high-frequency scheduling requirements, use XXL-JOB.
-
Optional: In the Advanced Settings area, you can also set the Time Offset, Time zone, and Effective Time.
The following table describes the advanced configuration parameters.
