System and method for monitoring and scheduling of middleware threads

Abstract

The invention discloses a system and a method for monitoring and scheduling of middleware threads. The system comprises a multi-thread middleware system and a middleware monitoring system. The multi-thread middleware system comprises a request dispatching component, a worker thread pool component and a monitoring and scheduling component which are in pairwise communication connection. The worker thread pool component consists of a plurality of worker thread groups which are grouped according to the IP address corresponding priority; the monitoring and scheduling component is used for presetting of the IP address corresponding priority, acquiring and processing data of working states of worker threads and servers to generate the system health rate and then feeding back the system health rate to the request dispatching component; the request dispatching component is used for acquiring the dynamic maximum number of available threads according to the system health rate and the maximum number of available threads, and dispatching the worker threads according to the dynamic maximum number of the available threads and the IP address priority. The number of the available threads is adjusted dynamically; when the system is in a poor health state, requests of users are rejected, so that the jam which is possible in high-concurrent access is overcome and running stability of the middleware system during the high-concurrent access is improved.

Description

Technical field [0001] The present invention relates to a monitoring and scheduling system, in particular to a monitoring and scheduling system for middleware threads, and also to a monitoring and scheduling method of the above system. Background technique [0002] The middleware system refers to the software that refines and abstracts the common problems faced by the application software in order to reduce the complexity of the business system development process and improve the processing capacity of the system, and then form a reusable part on the operating system Function collection. In order to cope with high concurrent access requests, general middleware systems are multi-threaded, and are called multi-threaded middleware systems. [0003] Such as figure 1 Shown are traditional multi-threaded middleware systems and middleware monitoring systems (monitoring systems of middleware systems). The multi-threaded middleware systems include request distribution components, applicati...

Problems solved by technology

[0005] Although the traditional multi-threaded middleware system guarantees the performance and stability of the multi-threaded middleware system to a certain extent in the above work process, it still has the following defects: (1) When there is no available worker thread in the worker thread pool, it waits for an available worker thread, Causes receiving thread blocking phenomenon, which is especially obvious during high concurrent access; (2) It is impossible to monitor and stop abnormal worker threads with too long execution time, and it is also unable to monitor deadlocks between worker threads in the worker thread pool, so the above two problems cannot be solved In this case, the system resources will be exhausted; (3) there is no early warning mechanism, and the middleware monitoring system will know and issue a warning only when the system cannot provide external services

Therefore, the traditional multi-threaded middleware system is prone to instability when dealing with high concurrent access
