The tab opens a page that shows all of the effective constraints and facts for a Grid object. Each Grid object has an associated set of facts and constraints that define its properties. By changing the policy constraints and fact values for a job, you can change the behavior of the job and how the PlateSpin Orchestrate Server allocates available system resources to it. The Orchestrate Server assigns default values to each of the component facts, although they can be changed at any time by the administrator unless they are read-only. Facts with mode r/o have read-only values, which can be viewed (by using the pencil icon), but changes cannot be made.
