Refined concurrency control device and method

Abstract

The invention provides a refined concurrency control device and method. The device comprises a concurrency number control module and a single channel processing module, and the two modules provide concurrency control for an application system. The concurrency number control module is used for controlling the concurrency numbers of functional modules of the application system not to be larger than respectively largest concurrency numbers. The single channel processing module is used for avoiding repeated requests for the same operation of the application system. The device and method are used for carrying out concurrency control over access operations on the application system in the aspect of total quantity and singular resource, using efficiency of application resources of the system is optimized, and the optimizing result is transmitted level by level, so that the resource utilization efficiency of the whole application system is optimal.

Description

technical field [0001] The present invention relates to the technical field of network control, in particular to a refined concurrency control device and method. Background technique [0002] With the rapid development of the Internet, the number of visits to each Internet application is increasing. At the same time, the Internet application itself is also using various internal and external resources. Whether it is processing external visits or initiating visits to other systems, an efficient The concurrency control mechanism enables reasonable utilization of resources and at the same time protects the stability of its own system. At present, the commonly used concurrency control technology is generally controlled for a certain total amount, and only controlling the total amount may easily cause resource competition under the total amount. For example, users who initiate 100 query requests in one second must be more than Users who send only one query request per second hav...

Problems solved by technology

Secondly, most of the currently commonly used concurrency control technologies still use the blocking method for synchronous control. For example, a system has implemented an upper limit of 1000 total control and synchronous control on the operation of "generating orders". In the worst case, When an order is generated very slowly, 999 orders will be blocked later, which will easily cause memory resources to be exhausted and cause the system to crash, and the system stability will become weaker

Finally, the single-channel processing mode is rarely used in the current concurrency control technology. For example, for the business of "modification order", under normal circumstances, when concurrency control is performed on it, when a user is performing this operation, all other users (including himself) cannot perform this operation at the same time, and the single-channel processing mode is to realize that when a user modifies an order, he cannot modify it again at the same time, but other users can still modify their own orders, and they do not affect each other , since the system separately provides them with a single processing channel
