Evaluate the Impact of Changing Configuration Item of Enterprise Information System Based on Graph Theory

Abstract

This paper establishes an enterprise information system configuration management model based on graph theory. Comb all nodes support enterprise information systems for the application system, host, operating system, middleware, database, applications, a database instance, network devices, storage devices, virtual host, virtual platform,11 kinds of configuration items. And sort out the relationships between them to no effect, no effect of virtual relationship, positive impact, positive impact of virtual relationships, reverse impact, reverse impact of virtual relations,6 kinds of relationships. All configurations supporting enterprise information systems and the relationships of them is seen as a weighted digraph. Then the weighted digraph is represented as an edge weight matrix. The edge weight matrix of a particular application system configuration relationships graph is solved according to the edge weight matrix of global configuration relationships graph, Help Operations staff clearly identify the composition of the information systems. The edge weight matrix of the impact of a change on a configuration item is solved according to the edge weight matrix of global configuration relationships graph. Provides a valuable reference views to operations staff when they repair a configuration.
