Scheduling Agent Jobs
The Integration Manager console allows you to set a schedule for agent-executed jobs using a cron expression, which is a specially formatted text string.
The example below is a cron expression representing a schedule that will run at 1:25 P.M. on the first day of each month.

Building a Cron Expression
A cron expression is composed of 6 or 7 values separated by spaces. Each of these values represents part of the schedule and can be either a number or a certain special character.
