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
The present invention relates to network control technical field, relate in particular to one become more meticulous concurrent control device and method.
Background technology
Follow the fast development of internet; the visit capacity of each internet, applications is rising; internet, applications self is also being used various inside and outside resources simultaneously; process external access or initiate the access to other system no matter be; all need a kind of concurrent control mechanism efficiently so that resource can rationally be utilized, protect the stable of self system simultaneously.Conventional Concurrent Control is all generally to control for a certain total amount at present, only total amount is controlled and easily caused the situation of the resource contention under this total amount to occur, such as the user who initiates 100 inquiry request 1 second, certainly to find the probability of result than the user who only sends out 1 inquiry request 1 second large, the appearance of this race condition provides a back door in fact just to a lot of people, also will cause the unreasonable of system resource use and waste simultaneously.In addition a lot of systems have been carried out respectively concurrent control to different business, but the similar business of some of them can not be merged together and be controlled, such as a certain system has been carried out concurrent control to " webpage inquiry entrance " and " webservice inquires about entrance " respectively, but they are inquiry same resources in fact, can put together and carry out concurrent control, for the e-commerce system becoming increasingly complex at present, it is necessary that this mode that multiple module independent assortments are carried out to concurrent control is provided.Secondly, the obstruction mode mostly still using at present conventional Concurrent Control is carried out synchro control, such as a certain system has been carried out overall control and the synchro control of the upper limit 1000 to " generation order " this operation, in so the worst situation, in the time that a certain order generation is very slow, to there be 999 orders to get clogged below, and be easy to like this cause memory source etc. to exhaust and a little less than causing system crash, such system stability can become.Finally, in current Concurrent Control, also seldom use single pass tupe, such as for " amendment order " this business, while generally it being carried out to concurrent control, in the time that a certain user is carrying out this operation, other all users (comprising himself) cannot carry out this operation simultaneously, and single pass tupe be to realize when a certain user be that oneself cannot be modified simultaneously again when order in amendment, but other users still can revise the order of oneself, they are independent of each other, because system offers respectively their single treatment channel.
Summary of the invention
In view of this, the invention provides one become more meticulous concurrent control device and method, by the accessing operation of application system being carried out to the concurrent control that overall control and resource are single, optimize the service efficiency of system applies resource, and the result of this optimization is transmitted step by step, the resource utilization of whole application is maximized.
