  ABSTRACT: The dependability of CORBA systems is a crucial issue for the development of today's distributed platforms and applications. This paper analyzes various techniques that can be applied to the dependability evaluation of CORBA systems. Due to the complexity of a middleware platform like CORBA and its various types of software components, experiments using several fault injection techniques are required to obtain comprehensive dependability benchmarks. To illustrate one of these techniques, we have applied fault injection at the communication level, targeting requests to major CORBA services, such as naming and events. Experiments have been carried out on a number of off-the-shelf implementations of CORBA. We present and discuss some of the results that we have obtained. They provide objective insights into the system's behaviour in the presence of faults, and are significant inputs for the selection of a candidate for a given application domain.

  ABSTRACT: The goal of this paper is to assess the value of simple features that are widely available in off-the-shelf CORBA and Java platforms for the implementation of fault-tolerance mechanisms in industry-grade systems. This work builds on knowledge gained at LAAS from previous work on the prototyping of reflective fault tolerant frameworks. We describe how we used the interception and state capture mechanisms that are available in CORBA and Java to implement a simple replication strategy on a small middleware-based system built upon GNU/Linux and JOrbacus. We discuss the benefits and the limits of the resulting system from a practical point of view.
