Exemplary system and computer program product embodiments for resource allocation of a plurality of resources for a dual activity system by a processor device, are provided. In one embodiment, by way of example only, each of the activities may be started at a static quota. The resource boundary may be increased for a resource request for at least one of the dual activities until a resource request for an alternative one of the at least one of the dual activities is rejected. In response to the rejection of the resource request for the alternative one of the at least one of the dual activities, a resource boundary for the at least one of the dual activities may be reduced, and a wait after decrease mode may be commenced until a current resource usage is one of less than and equal to the reduced resource boundary.
