Design Pattern for Dynamic Reconfiguration of Component-based Autonomic Computing Systems using RMI

With the help of Autonomic Computing System characteristics, we can develop the applications to be more adaptive to the changes that take place at the run-time. When designing software, in most cases two or more patterns are to be composed to solve a bigger problem. In this paper we will propose a Design Pattern which is an amalgamation of Worker Object Aspect Oriented Design Pattern, Lookup Design Pattern, Row Data Gateway Design Pattern, Observer Design Pattern, Component Insertion and Component Removal Design Patterns for Dynamic Reconfiguration of Component-Based Systems using RMI. Our proposal mainly focuses on the efficient method of accessing the web services in a distributed environment. We were successful in providing the Self-Reconfiguration between the currently existing Components in the system and newly inserted/removed components within a system in a distributed environment. We have used the Asynchronous RMI distributed computing mechanism to successfully insert and remove the components within an application/system in run-times.
