Generic Action Support for Distributed, Cooperative Applications

Elements of transaction processing become more and more accepted as a base for general purpose distributed computing.We have developed an action concept with an extended functionality suited to better support the needs of future important application fields such as Cooperative Work and Concurrent Engineering. Its main characteristic is its orthogonal design of recovery mechanisms allowing to apply a variety of flexible concurrency control mechanisms. Our current implementation, being a milestone in the development of our cooperative action support, implements non-strict two-phase locking as concurrency control mechanisms and includes (nested) transactions as a special case. A clear separation between distributed action management and management of the resources used by actions is the basis for extensibility. Following the X/Open model for distributed transaction processing, distributed action management is isolated in a server (the so-called Action Manager (AM)) on every site which co...
