Setting the constraint expiration time
The pmgui.scheduler.constraints.expire system property indicates the number of days, prior to the current date, before which all constraint time periods expire. The default value is 30 days. For example, if you keep the 30-day default, a blackout period that ended 31 days ago is not used as a resource constraint. You can set a different expiration value.
About this task
The pmgui.scheduler.constraints.expire system property limits the amount of data that is sent to your browser client. Scheduling begins with the present and extends into the future; therefore, out-of-date resource constraint data is not usable and does not need to be retained.
To set a different expiration time, go to the System Properties application (), open the pmgui.scheduler.constraints.expire property, and supply a different number in the Global Value field.
