Abstract

Dynamic software updating (DSU) is an extremely useful feature to be used during the software evolution. It can be used to reduce downtime costs, for security enhancements, profiling and testing the new functionalities. There are many researches and solutions on dynamic software updating regarding diverse problems introduced by the topic, but there is a lack of research which compare various approaches concerning supported changes and demands on re-sources. In this paper we are comparing currently available con-cepts for Java programming language that deal with dynamically applied changes and impact of those changes on computer resource demands.
