“…There is a need for a portfolio approach to virtual meeting support containing complementary products from different suppliers, able to coexist technically to provide a seamless solution to the user. The use of coexisting and complementary products will require specific attention to be paid to coordination, resilience and selection management and as such will draw on previous work in this area from within the Distributed Systems and Modelling research group [14,15,16].…”

Virtual meeting environments are providing a viable alternative for conventional meetings bringing benefits of reduced costs and better use of time by removing the need for attendees to travel to national, international or global locations in order to attend meetings. This paper builds on the work of previous papers which discussed the functional and technical requirements for a virtual meeting system, reporting on a user trial and evaluating the prototype system. The trial was performed by students as users deploying the prototype for collaboration in group work focussed on the design of a computer system as part of the final year of their undergraduate study. The users were asked to comment on the features of the prototype as well as offering suggestions on useful features that should be included in a virtual meeting system. A summary of their comments and suggestions and the results of the evaluation are included in the paper. Security aspects of virtual meeting systems are also considered in some detail.

Web services (WS) transactions are important in order to reliably compose distributed and autonomous services into composite web services and to ensure that their execution is consistent and correct. But such transactions are generally complex and they require longer processing time, and manipulate critical data. Thus various techniques have been developed in order to perform quality assessment of WS transactions in terms of response time efficiency, failure recovery and throughput. This paper focuses on the testing aspect of WS transactions -a key issue that has not been examined in the literature. Accordingly it proposes multi-dimensional criteria for testing the WS transactions. The proposed criteria have the potential to capture the behaviour of WS transactions and to analyze and classify the possible (failure) situations that effect the execution of such transactions. These criteria are used to generate various test cases and to provide (WS transactions) tester with flexibility of adjusting the method in terms of test efforts and effectiveness. The proposed criteria have been designed, implemented and evaluated through a case study and a number of experiments have been performed. The evaluation shows that these criteria have the capability to effectively generate test cases for testing WS transactions as well as enable tester to decide on the trade-off between test efforts and the quality.

“…[5] uses definable constraints to relax atomicity and avoid unnecessary recovery. An adaptive relaxation approach towards ACID was proposed in [11] by adding a 'pre-commit' phase and the decision is finally given by user intervention. S. Choi et.al.…”

The Internet has been encouraging and enabling business collaborations via online transactions over the Web. However, managing transactions in a long-running business process across domains still remains a challenge. In this paper, we propose a novel financial-compensation-based transaction management model, fcBTxM, to address this challenge. Unlike classical transaction management, fcBTxM does not attempt to recover data consistency via rollback when a failure occurs. Instead, our model always tries to forward-roll a business process via financial compensation. We use a state machine to capture and describe the states of our transaction model and their relationships. We also develop a set of technologies and protocols for enabling the new transaction management. A real business collaboration example is used to demonstrate the concept, and preliminary testing results are provided to evaluate our technologies.
