Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the service dynamic update efficiency is low. The method dynamically calculates the nodes that may be executed at the time of service execution through dynamic analysis, and provides a more accurate and real-time dependency topology map, thereby improving the work efficiency of the existing dynamic update technology

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] The improved method of the present invention refers to using the data at the running time of the service to calculate the nodes that the service may be executed in advance in real time, so as to provide more accurate service dependency information. As a result, the dynamic update algorithm can be performed on a more accurate and real-time dependency topology graph, so that the dynamic update is advanced and the system pause is shorter.

[0016] The dynamic analysis method in the BPEL-based service of the present invention mainly includes the following tasks:

[0017] 1. Model the BPEL process: build an efficient model for the BPEL process according to the characteristics of BPEL. The main idea of ​​the modeling is to build the BPEL process into a directed graph. For structured nodes (including domains, branches, loops, concurre...

Abstract

The invention discloses a method for improving service dynamic updating efficiency. The method can predict the node at which the service is possible to be executed in advance by using data information at the moment of dynamically operating the BPEL flow, thereby further providing powerful basis for inter-service dependency analysis and dynamic service substitution.

Description

technical field [0001] The invention belongs to the field of computer applications, and is specifically based on the dynamic analysis of the BPEL flow, so as to improve the efficiency of service dynamic update. Background technique [0002] With the continuous development of network and distributed technology, the means of providing services based on network services is gradually becoming the mainstream. As a manifestation of software, service will inevitably face the problem of updating and upgrading. The most basic approach is to stop the service, then update the service, and then start the service until the service is updated. Suspension of service will inevitably bring huge troubles to customers and bring economic losses to businesses themselves. At the same time, service suspension will lead to loss of service data, which may also bring unnecessary troubles to both parties. Faced with these problems, dynamic update technology is a good solution. [0003] At present,...
