ReflecTS

Transactional requirements, from applications and execution environments, are varying and may exceed traditional ACID properties. We believe that transactional middleware platforms must be flexible in order to adapt to these requirements. Present systems are, however, inflexible with respect to such adaptations. ReflecTS is a flexible transaction processing platform maintaining an extensible number of concurrently running transaction services. This paper presents the architecture and the first prototype of ReflecTS, which focuses on a transaction service selection procedure. The selection procedure is based on XML-specifications of transactional requirements and transaction service descriptions-making the platform adjustable to varying requirements.
