Propagation Types

Propagation type defines how CA SOI derives the impact when conditions change in related objects. Every relationship in a service model has a propagation type, and each USM relationship type maps to a specific propagation type in CA SOI. The propagation types are as follows:

• Aggregate
• Bound
• Custom
• Operative

Relationships are depicted as arrows between two CIs in the Topology view. The color of the arrow reflects the propagation type of the underlying relationship. The Topology view is available on the Operations Console and the Service Modeler. The first letter of the propagation type is a label on the arrows (A, B, C, or O for Aggregate, Bound, Custom, and Operative, respectively).

Note: Sometimes the arrows are animated red dashes to indicate the root cause of a situation.
