Job Scheduling

Overview

Integration Manager supports both Interval and Cron expression scheduling. The powerful Quartz scheduler engine is used to manage scheduling and schedule triggers.

Interval Scheduling

Interval scheduling is a convenient way to setup an integration to run every X hour(s) and/or X minute(s).

Note that the interval scheduling smallest unit is 1 minute.

Cron Expression Scheduling

Cron expression scheduling is a much more powerful and flexible scheduling mechanism. It uses a special syntax to specify the exact second, minute, hour, day of month, month, day of week, and/or year that a schedule will fire.

A simple example is a cron expression representing a schedule that will run at 1:25 p.m. on the first day of each month:

0 25 13 1 * ? *

It takes a little bit of practice, but cron can come in very handy to customize exactly when your integration jobs will run.

Note that cron scheduling in increments of less than 1 minute is disabled by default. You can enable increments down to the second by adding the following entry to your application.properties file (requires Integration Manager restart):

org.quartz.ext.allow-seconds=true
