    摘要: Methods, systems and computer program products are provided for error recovery in a network having a first application associated with a first endpoint node and a second application associated with a second endpoint node. These methods, systems and computer program products non-disruptively switch the first application associated with the first endpoint node to a third endpoint node arbitrarily selected from existing endpoint nodes when the first endpoint node is no longer available to the second application associated with the second endpoint node. The first application is provided on the third endpoint node in substantially the same state as the first application existed on the first endpoint node prior to the unavailability of the first endpoint node. The present invention is preferably carried out where the endpoint nodes are VTAM facilities. Also, the first and third endpoint nodes are VTAM facilities in the same SYSPLEX.

    摘要: Disclosed is a method for modifying the frequency response of a wood panel within an acoustical structure such as a studio or concert hall. The modification is imparted by exciting the wood paneling with acoustic energy. Frequency response is the measure of a system's spectrum response at the output to a signal of varying frequency (but constant amplitude) at its input. The acoustic energy includes at least one excitation frequency, which is preferably in the audible spectrum (20 to 20,000 Hz). The use of acoustic energy from the remote source provides non-contact excitation of the wood paneling. In one embodiment, the acoustic energy is at least one sound wave which comprises at least one resonant frequency of the wood paneling, at least one acoustic mode of the wood paneling, at least one discrete broadband frequency, a composite frequency (including multiple broadband frequencies, white noise and pink noise) or any combination thereof.

    摘要: Methods, systems and computer program products are provided for transferring a Virtual IP Address (VIPA) from a first application instance to a second application instance executing on a cluster of data processing systems having a plurality of communication protocol stacks. A list of dynamic VIPAs is distributed among the protocol stacks and a hierarchy of backup communication protocol stacks for the dynamic VIPAs is determined based on the list of dynamic VIPAs. Upon receiving notification of failure of the first stack the second stack evaluates the hierarchy of backup stacks to determine if it is the next stack in the hierarchy for the VIPA associated with the first application instance. If so, then the VIPA associated with the first application instance is transferred to the second communication protocol stack associated with the second application instance.

    摘要: An electronically controlled mask shield for a wave soldering machine is disclosed which can be positioned to shield gold contacts on printed wiring boards (PWBs) during a wave soldering operation. The shield is a trough shaped member that is attached by a frame assembly to a conveyor rail of a conventional wave soldering machine. The frame assembly includes a pair of support sleeves to which the two ends of the shield are attached. The support sleeves are movable with respect to the conveyor rail between a retracted position and any desired extended position by means of a motor, and a chain and sprocket drive mechanism. A motor control circuit enables the shield to be positioned as desired, and a position responsive sensor is attached to the drive mechanism to provide signals for a position indicating display. The motor control circuit can be either manually controlled, or automatically controlled by a microprocessor.
