摘要： A load sharing system composed of a plurality of servers that are interconnected over a network for providing optimum and efficient operations at high reliability. The system employs a plurality of servers and a communication controller. A state manager in the communication controller first establishes connection paths on the network to reach the state management agents. The state manager then performs a centralized management of activity status of the servers based on status information collected from the state management agents via the established connection paths. A distribution processor disposed in the communication controller receives service requests from user terminals via a network and determines their respective destinations according to management data provided by the state manager. The distribution processor then forwards the service requests to the servers over the communication medium to direct their execution. An operation controller activates or deactivates a plurality of parameters which will define how to distribute the service requests to the applications.

摘要： A program recording medium recording a communication control program to be implemented in a computer including a plurality of control means for controlling data communication in a hierarchical configuration and data transfer control means for controlling data transfer among the plurality of control means. The program causes the data transfer control means to add anomaly information into data to be transferred to the plurality of control means upon detection of the anomaly indication, to send discard indication, that is the data containing the added anomaly information, at substantially the same time to the plurality of control means, and to discard the data containing the anomaly indication and data relating thereto.

摘要： In a business system constructed by a web server, an AP server, and a DB server serially connected in this order, the times required for the transmission and reception of messages with respect to the servers or business applications located in downstream processes of the servers, are respectively measured. Then, performance information associated with, at the very least, these times is created for the identifier that identifies the business application, and this is transmitted to and collected in the administration server. The processing time spent in each server and business application, if under normal circumstances, is very small. Therefore if this deviates from a predetermined range, it can be easily identified that the business application thereof is being a bottleneck.
摘要翻译：在由服务器，AP服务器和与该服务器的下游进程中的服务器或业务应用程序相关联的数据库服务器和数据库服务器构成的业务系统中，发送和接收消息所需的时间，分别测量。然后，至少与这些时间相关联的性能信息被创建用于识别业务应用的标识符，并将其传送到管理服务器并被收集在管理服务器中。在每个服务器和业务应用程序中花费的处理时间，如果在正常情况下，是非常小的。因此，如果这偏离预定范围，则可以容易地识别出其业务应用是瓶颈。
