Integration of a dynamic object replication framework in Java

Abstract

By the use of dynamic replication schemes -in comparison with static replication schemes -a tremendous increase of read and write operation availabilities can be achieved. Furthermore, object-oriented programming languages like Java offer excellent possibilities for the abstraction of complex problems. In this paper, we present our solution of combining dynamic replication and its use in object-oriented programming. More precisely, we show how Java objects can be made highly available through the use of dynamic replication in an almost transparent manner from the Java application programmer's perspective. This is done by using a general, highly flexible framework which enables the use of a large number of dynamic replication schemes. We show how the framework can be integrated, such that it is conveniently available for Java application programmers. We demonstrate its simple use, even when being introduced a posteriori in a Java program: one need only to modify a few lines of code.
