摘要： Provides control of the workload, flow control, and concurrency control of a computer system through the use of only external performance monitors. Data collected by external performance monitors are used to build a simple, black box model of the computer system, comprising two resources: a virtual bottleneck resource and a delay resource representing all non-bottleneck resources combined. The service times of the two resource types are two parameters of the black box model. The two parameters are evaluated based on historical data collected by the external performance monitors. The workload capacity that avoids saturation of the bottleneck resource is then determined and used as a control variable by a flow controller to limit the workload on the computer system. The workload may include a mix of traffic classes. In such a case, data is collected, parameters are evaluated and control variables are determined for each of the traffic classes.

摘要： A method and system for controlling load admission rate of an application server is provided. In the method, actual heap utilization and load admission rate of the application server in current control cycle are detected; based on the detected actual heap utilization and load admission rate, load characteristics variation parameters of the application server are estimated; and control gain of a feedback controller is calculated based on the load characteristics variation parameters; the feedback controller calculates desired load admission rate of the application server in next control cycle by using the calculated control gain. The load admission rate of the application server can be adaptively controlled by tracking changes in workload characteristics of the application server, such that the actual heap utilization of the application server is maintained at or close to target heap utilization.

摘要： The invention discloses a programming method and system for dynamic client/server network management using proxy servers, by allowing each active proxy server in an arrayed cluster to maintain an updated list of all other operating proxy servers in the cluster. When a client message requesting access to an application server is received by a clustered proxy server, the message may be forwarded to another proxy server (within the cluster) so that message (re)transmissions can pass through the same proxy server as the original message, allowing a proxy server to make consistent routing decisions (and other decisions) pertaining to that message.
