In modern service oriented architectures (SoA) identifying the occurrences of failure is a crucial task, which can be carried out by the creation of diagnosers to monitor the behavior of the system. Model driven architecture (MDA) can be used to automatically create diagnosers and to integrate them into the system to identify if a failure has occurred. There are different methods of incorporating a diagnoser into a group of interacting services. One option is to modify the BPEL file representing services to incorporate the diagnoser. Another option is to implement the diagnoser as a separate service which interacts with the existing services. Moreover, the interaction between the diagnoser and the services can be either orchestration or choreography. As result, there are four options for the implementation of the diagnoser into the SoA via MDA. This paper reports on an Oracle JDeveloper plugin tool developed which applies MDA to create these four possible implementations and compares the performance of them with the help of a case study.
