Abstract

Developing software applications which manage, optimize or adapt themselves at runtime requires an architecture which provides adaptation of software components at runtime. An architecture model that has gained a lot of attention in recent years is SOA (service-oriented architecture). In a SOA environment services as well as applications build up complex dependencies. Therefore it is crucial for self-managing SOA applications to adapt services at runtime without interference of the application execution and the service availability. In this paper, we discuss the problems arising from the requirement of runtime adaptation and present our solution by replacing service implementations at execution time in a service-oriented component model. For a seamless integration we strive for a transparent and atomic replacement of a service implementation in respect to the other services/applications.
