<CENTER> <h1>Using Service Configurator Framework</h1> </CENTER>
<P>When building distributed systems, there will almost certainly
be multiple processes or services running at all
times. It is helpful if these services can (re)configured and
control at installation-time or run-time. In this tutorial, we
illustrate how to configure services in a fine-grained manner,
rather than having to stop and restart all services in an application. </P>
<P>The examples we show are based on the <A HREF="http://www.cs.wustl.edu/~schmidt/POSA/">Component Configurator</A> pattern,
which enables a service to be started, removed, suspended or resumed
dynamically. This pattern decouples the implementation of a
service from its (re)configuration. Thus, new services can be added or unnecessary services
can be suspended or removed.</P>
<P>In this tutorial, we will use the simple server and client
which we developed and used in our tutorial 005 as the base and
modify it as needed.</P>
