A strategy for validating an ODBMS component using a high-level Software Fault Injection tool

Abstract

We present a strategy for the validation of an Object Oriented Database Management System (ODBMS), an off-the-shelf component software, when we deliberately introduced faults and observe its behavior in the presence of these faults. A tool designed for the injection of faults in OO applications, specially Java language systems, was used. This Software Fault Injection tool, Jaca, was developed at UNICAMP and has the ability to inject faults in objects' attributes and methods. For the experiments we used an ODBMS performance test benchmark, Wisconsin OO7. The experiments were aimed at validating the robustness of the ODBMS component in the presence of errors originated at the application. For that purpose a fault injection strategy was proposed to help answer the questions: Where to inject? What error model to use? This strategy was applied, so some results and their analysis are presented. Improvement for Jaca were addressed as a experiments' result. © Springer-Verlag Berlin Heidelberg 2003.
