With the development of society and science and technology, various business transaction display and operation modes are developed from the traditional character simulation terminal to the traditional various graphical terminals, the input and output capability and the man-machine interaction friendliness are greatly changed, and the traditional graphical over-the-counter transaction processing system consists of a client side and a server side. The client is mainly responsible for drawing, rendering, operation control, equipment calling, data entry, data verification and processing of part of simple business logic of the view; the server is mainly responsible for processing complex business logic of transactions and providing public capabilities such as authorization, rechecking, pipelining, printing, identity verification, communication connection and the like.
The traditional transaction processing mechanism is as follows: and opening a transaction interface at the client, inputting or reading corresponding business data from the counter equipment by the teller according to the business elements, triggering the submitting operation, and then sending the business data to the server for processing. After receiving the request, the server side allocates a processing thread to the request, the thread synchronously executes all operations according to a preset processing flow, and returns a final execution result to the client side, and the whole process is basically synchronously called according to a single processing flow. However, if a module in the system processing takes time to increase gradually or a time-consuming abnormal condition occurs, the overall processing capability of the system is involved, and finally the system is in an unavailable state, and under the abnormal condition, the existing system has the following defects:
