Setting Resource Type Properties for Scheduling
Property-based scheduling is a standard capability of the Active System Manager scheduler. It applies only
to the scheduler’s selection of resource types. If you author a resource instance, then there is no scheduler
selection available. When you create a session, the Active System Manager scheduler checks the
availability of resources required by the Template at the specified time and reserves them. If a resource
instance is required, then only that particular resource is reserved for that element in the Template, and is
used when realizing the Template. If a resource type is required, then the scheduler looks for any resource
of that type having the minimum required interfaces available. In addition, the scheduler verifies that other
properties match the values that you specified for the resource and its interface. This is called
property-based scheduling.
To set resource type properties for scheduling, perform the following steps:
1. In your Template, select a resource type and click the Inventory tab.
2. Set the preferred or required property check box status.
A property for scheduling can be treated in two different ways:
• By default, properties are “Preferred”; that is resources or interfaces that match this property-value
condition are the first choice. The Active System Manager scheduler attempts to find a solution that
fulfills all of the requirements in the Template, including matches for the preferred properties. If the
preferred properties are not found, the scheduler seeks solutions that are not restricted to the
specified properties.
• Clicking the Required check box means that only resources or interfaces that match this
property-value condition can be used. If an exact match cannot be found, any attempts to schedule
a session based on this Template fails. In the property list, if a check box is selected next to a
property, this indicates that the property is “Required”.
3. Click the Operator column field and select an operator. The list of operators depends on the property
type.
4. Click the Value column field for the associated property and enter a value. When the light bulb displays,
it means that control assistance is enabled. Press Ctrl+spacebar to search and display all possible
values for that property; see Figure 11-16.
