摘要： Embodiments of the present invention address deficiencies of the art in respect to workload management of backend systems and provide a novel and non-obvious method, system and computer program product for limiting a request rate from a client based on a health state of a server system. In one embodiment of the invention, a computer-implemented method for limiting a request rate from a client based on a health state of a server system that includes monitoring a server system, determining a measure of health of the server system, sending the determined measure of health to a client submitting a request to the server system and receiving a subsequent request from the client that is delayed by a time period, wherein the time period is based at least in part upon the determined measure of health. The computer-implemented method can further include receiving server system CPU utilization, determining an approximate predicted real server response time of a transaction and sending the determined approximate predicted real server response time of a transaction to a client submitting a request to the server system.

摘要： A method for enabling connectivity for protocol aware applications across different network topologies can include receiving frames passing between a first network having a first network topology and a second network having a second network topology; inspecting an incoming one of the frames to identify a remote resource in the second network and a device identifier corresponding to the remote resource, and an outgoing one of the frames to identify a socket assigned to a local resource in the first network and a device identifier for the local resource corresponding to the socket; and, transmitting data from a protocol-aware application in the first network to the remote resource in the second network in a protocol consistent with the second network topology, and further transmitting data from the remote resource in the second network to the protocol-aware application in the first network in a protocol consistent with the first network topology.

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.
摘要翻译：提供了方法，系统和计算机程序产品，用于将虚拟IP地址（VIPA）从第一应用程序实例传送到在具有多个通信协议栈的数据处理系统的集群上执行的第二应用程序实例。动态VIPA的列表在协议栈之间分配，动态VIPA的备份通信协议栈的层次结构基于动态VIPA列表来确定。在接收到第一堆栈的故障的通知之后，第二堆栈评估备份栈的层次结构，以确定它是否是与第一应用实例相关联的VIPA的层次结构中的下一堆栈。如果是，则与第一应用实例相关联的VIPA被传送到与第二应用实例相关联的第二通信协议栈。
