Embodiment Construction

[0021] In order to facilitate those of ordinary skill in the art to understand and implement the method proposed by the present invention, the present invention will be further described in detail and in-depth through specific embodiments below.

[0022] A memory leak (Memory Leak, hereinafter abbreviated as ML) is a common fault. In this aspect, an ML fault is taken as an example to describe the method. The ML failure is described in natural language as follows.

[0023] Defect No. 82 (number #82), deployed to the actual environment, after the system continues to run for a period of time, the software high-precision computing module takes up more and more CPU resources.

[0024] Step 1: After preprocessing and analyzing the failure described in natural language, get F(Name,Time,Location,Description)=F(82, "after the system has been running for a period of time", "software high-precision calculation module", "occupying more and more CPU resources").

[0025] Step 2: Use the...

Abstract

For the problem that the conventional software fault classification methods do not consider new characteristics of a complex software intensive system, the invention provides a complex software intensive system oriented fault classification method which fully considers the new characters such as logic complexity and boundary corrosion of the complex software intensive system, can classify faults according to the life periods and fault classes, and can determine each classification attribute value of fault classification through artificial determination and machine automatic identification. The complex software intensive system oriented fault classification method can improve the accuracy and the precision of fault class division and recognition of the software intensive system, and provides a basis for fault injection research and failure mechanism research of the complex software intensive system.

Description

technical field [0001] The invention relates to the technical field of fault classification of software systems, in particular to a technology for fault classification research of complex software-intensive systems. Background technique [0002] With the rapid development of computer software and Internet technology, the interaction between software and other software, systems, equipment, sensors, and people has become increasingly close, so the concept of software-intensive systems has emerged. A software-intensive system refers to a system in which software plays a central role in the process of system design, construction, deployment and evolution, such as the Global Information Grid (GIG) planned by the US Department of Defense, Boeing777 aircraft information management system (AIMS) and so on. Complex software-intensive systems, especially safety-critical software systems in the field of national defense and military affairs, once they fail, will cause immeasurable con...
