Large scale interoperability and distributed transaction processing
John A. Mills · 2003
This paper integrates an interoperability architecture, the OSCA architecture, and a distributed transaction processing protocol, the X/Open distributed transaction processing model, into a unified model of large scale interoperability and distributed transaction processing. Applications supporting different business operations are often deployed in heterogeneous environments in which operations often are fragmented. In order to have integrated operations, a loosely coupled system of autonomous applications is required frequently bound together by a distributed transaction processing protocol. This paper describes a model for this configuration. It proposes that the span of control of a transaction manager defines the transaction environment for a single building block, where any two building blocks may not conform to the same supplier's transaction environment. Requirements are imposed upon the interactions of building blocks to support interoperability.>
