Setting Discriminators in the Administration Tool
You can also attach Discriminators to Services in the GridServer Administration Tool, at Services > Services > Service Conditions. This page enables you to create Discriminators by entering three defining factors: the Services that the Discriminator affects, the types of Engines that can run on those Services, and optionally, if an EXTRACondition must be met. (See EXTRAConditions for more information about EXTRAConditions.) This differs from programmatic Discriminators because they aren’t explicitly attached to a Service at its creation; instead, a group of Services is defined as being attached to that Discriminator, by Service name, application name, department name, or wildcards on that or other criteria.
By default, changes made to Discriminators in the GridServer Administration Tool are applied to Services immediately. This can be changed so that Discriminator changes only apply to subsequently created Services. To change this behavior, go to Admin > System Admin > Manager Configuration > Services, and under the Scheduling heading, change the value of Apply Condition Admin Changes Immediately.
