Problems solved by technology

This leads to a downward spiral as the server has many incoming connections, making the database performance degraded by resource consuming locking processes
Poor database performance causes delays in request processing, which in turn increases the number of concurrent requests to be processed
[0005] Also, because a timeout is triggered, a request that is waiting for a long time on the server may be considered a failure even though it is eventually processed by the server

Abstract

The invention relates to a computer-implemented method for limiting the number of concurrent requests in a database system, said method comprising the steps of: queuing requests to be processed by said database system in at least one queue (10); The maximum value (SS) of concurrent requests of said at least one queue (10); monitoring at least one queue utilization parameter corresponding to said at least one queue (10), and calculating a performance value (PF ); dynamically adjust the maximum value (SS) of concurrent requests of the at least one queue based on the performance value (PF), so as to improve system performance, and dynamically limit the at least one queue based on the dynamically adjusted maximum value (SS). The number of concurrent requests for the queue (10).

Description

technical field [0001] The present invention generally relates to the field of database systems, and particularly relates to a database system for a server to access a database. More specifically, the present invention relates to a method and system for limiting the number of concurrent requests in a database system and thus reducing the occurrence of locking in a server / database system. Background technique [0002] In a traditional client-server architecture, one or more nodes are connected to one or more servers via a network that allows bi-directional communication between clients and servers. Typically, a server receives requests from multiple sources and processes them according to a prescribed processing scheme. More generally, a first-in-first-out (FIFO) method is used, allowing requests received first to be processed by the server first, requests received second second, and so on. In database systems, queues are used to process incoming requests from clients in or...
