Abstract
A method and apparatus for dynamically controlling the dispatching of a coupling facility operating in a logical partition sharing a processor resource with one or more other logical partitions issuing requests to the coupling facility. A plurality of coupling facility dispatching modes differing in their relative dispatch duration are defined. One dispatching mode is initially selected, and the number of requests received from the other logical partitions within a predetermined interval while in a selected dispatching mode is determined. Transitions between the defined dispatching modes are made in accordance with the number of requests received within the sampling interval in the selected dispatching mode. The method and apparatus are especially suitable for controlling the dispatching of a backup coupling facility, whose polling loop would otherwise consume processor resources usable by other logical
