Improving the Performances of JMS-Based Applications

In the Java world, a standardised interface exists for Message-Oriented Middleware (MOM): Java Messaging Service or JMS. Like other middleware, some JMS implementations use clustering techniques to provide some level of performance and fault tolerance. In this paper, the authors analyze the efficiency of various clustering policies in a real-life cluster and the key parameters impacting the performances of MOMs. They show that the resource efficiency of the clustering methods can be very poor due to local instabilities and/or global load variations.
