New Challenges for Configuration Management

Abstract

More and more systems are developed using components. There is a move from monolithic to open and flexible systems. In such systems, components are upgraded and introduced at run-time, which affects the configuration of the complete system. Keeping up-to-date information about which components are installed is a problem. Updating a component also affects the compatibility of the system. It is therefore important to keep track of changes introduced in the system. In the product life cycle, CM is traditionally focused on the development phase, in particular on managing source code. Now when changes are introduced in systems at run-time and systems are component-based, a new discipline, component configuration management is required. This paper analyses component management and highlights the problems related to component configuration. Requirements on component configuration management are outlined, and some directions to possible solutions of the problems are given.
