Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] First of all, two types of threads need to be determined in a multi-threaded system, one is the monitoring thread, and the other is the monitored thread. The monitoring thread and the monitored thread can use any thread in the system. The main task of the monitoring thread is to regularly contact the monitored thread, obtain the status of all the monitored threads and listen to the reported news of the monitored thread. Generally, the main control thread is used as the monitoring thread, and a thread can also be used as a full-time monitoring thread or use Any other thread in the task acts as a monitoring thread. The monitored thread is generally a worker thread in a multi-threaded system.

[0021] Roll call means that the monitoring thread actively sends a message to the monitored thread, and obtains the status of the monitored thread through the message re...

Abstract

The invention provides a method for realizing real time threads state monitoring in multiple thread system which comprises, setting one thread in a multiple thread system as a monitoring thread, the others being monitored threads, wherein the monitoring thread is used for contacting each monitored threads to know their operating modes, each monitored thread responding the message from the monitoring thread, and feeding back the working condition and other information of itself, the monitoring thread maintaining the thread status information chart, and the system employing different strategy according to the status of each thread.

Description

technical field [0001] The invention relates to multi-thread technology in the field of computers, in particular to a method for realizing real-time monitoring of each thread state in a multi-thread system. Background technique [0002] With the development of science and technology, in the development process of large-scale systems, it is often necessary to use multi-threading technology. In a complex multithreaded system, multiple threads need to work together, which is a relatively difficult task. The workload of coordinating the work of each thread occupies a considerable proportion in the workload of the whole system, and the algorithm is more complicated. Since any abnormal situation may occur during the operation of the system, if a thread is deadlocked or an exception occurs, but the main control thread does not know it, but still schedules tasks for the thread at regular intervals, it is easy to cause the task buffer to overflow, which in turn leads to Business fa...
