Abstract: A method for a messaging engine to control messaging within a virtual machine having a heap includes creating a list of destinations associated with a messaging engine and receiving parameters associated with the heap. The message production rates are controlled using the parameters and heap usage. For example, the parameters may include a lower limit that indicates that message production should be decreased (i.e., throttled back) and a step-down value. Using the lower limit and the step-down value, intermediate throttle-back thresholds are created, and when the heap usage transitions from below one of the intermediate throttle-back thresholds to above the intermediate throttle-back threshold, the message production rate is decreased. Further, other parameters may include an upper limit and a step-up value, which are used to determine intermediate throttle-up thresholds that indicate when the message production rate may be increased (i.e., throttled up).

Abstract: A method for a messaging engine to control messaging within a virtual machine having a heap is disclosed. The messaging engine creates a list of destinations associated with a messaging engine and receives parameters associated with the heap. The messaging engine determines total heap usage and based on the parameters associated with the heap and the total heap usage, controls message production rates of producers associated with the destinations.
