Abstract

To enable the interoperability of high availability (HA) middleware systems the Service Availability Forum has released a set of open specifications. The benefit of having open specifications is the choice of implementations available from different vendors. When one chooses a product, one of the selection criteria (besides performance) is the robustness of the implementation, as the crashing or hanging of such a HA middleware causes the failure of the whole system. The challenge is to develop the appropriate technology for measuring and comparing robustness of HA middleware implementations. Based on our earlier results, we present a set of automatic testing tools and a benchmark suite constructed using these tools. We demonstrate the robustness testing approach by comparing the results of benchmarking carried out on three HA middleware implementations.
