Abstract: Throttling polling may include sending a request to an agent device and determining whether a response to the sent request is successfully received from the agent device. A result of the determination may be stored in a memory and associated with the agent device. Further, a success rate is calculated for the agent device based on a plurality of the results. A metric related to the sent request and a subsequently sent request is adjusted for the agent device in accordance with an algorithm based on the calculated success rate for the agent device. The metric may be an amount of time between the sent request and a subsequently sent request for the agent device or a number of subsequently sent requests for the agent device.

Abstract: Problems with prior OSI (Open Systems Interconnected) event forwarding discriminators (EFD) are solved in accordance with this invention by creating a new type of EFD, called a notification forwarding discriminator (NFD). An NFD works just like an EFD in that it receives notifications emitted by managed objects and determines what types of notifications should be forwarded. However, the forwarding mechanism in an NFD is completely different. An NFD has two operations that a management application can use to control subscription to notifications, "start" and "stop". An NFD forwards notifications via responses to a solicited "start" operation without signaling the end of the "start" operation. Hence, a "start" operation will always be pending completion. The manager and agent track this pending status of operations between a manager and an NFD. Both the manager and agent maintain a pending completion list for each link between a manager and agent.

Abstract: A process of efficiently managing working storage that unifies the use of queues of fixed size free storage blocks and a global list of blocks of random size. The process implements continuous garbage collection that continually purges unused storage blocks from the fixed size queues to ensure maximum free storage availability. Data processing system throughput is enhanced by reducing the processor overhead required to allocate and return free storage blocks and by reducing the overhead required to manage temporary extensions of working storage.
