As the cost of computing power continues to decrease, it is worthwhile to consider the benefits of adding more of that computing power to the network itself, either to enhance services or to trade off against other costs such as time, bandwidth and storage. This new area of research is called Active Networking. Active networking represents a new approach in which network switches or nodes perform customized computing as the messages flowing through them. This paper proposes a novel approach to atomic commitment of transactions in distributed database systems. In our approach, active nodes participate in the process of atomic commitment of distributed transactions by maintaining passive \"blackboards\" which record voting status of participant subtransactions. One active node is delegated the coordinator function so that when rendezvous is there, commit decisions can be made. Since the decision is made from an internal network node (selected to be close to the participant nodes), the uncertainty time delay can be significantly reduced. This is especially critical in wide area networks. Other active nodes can be used to suppress duplicated votes sent in the upstream direction. Additionally, once a negative vote is received at any active node, children participants can be notified of the abort decision immediately and therefore much earlier than would otherwise be possible. This approach is shown to yield performance improvements over traditional methods, in terms of delay and network message traffic.","PeriodicalId":236128,"journal":{"name":"Proceedings 15th International Conference on Data Engineering (Cat.

Similar concepts are adopted for providing \"transaction-like\" behaviour for long business processes supported by workflows technology. Generally, designing a compensating task in the context of a workflow process is a non-trivial job. In fact, not every task is compensatable. This work contributes to the study of the non-compensatability problem. A compensating task C of a task T semantically undoes the effect of T after T has been committed. For example, the compensating task of a deposit is a withdrawal. For a task to be compensatable, it must satisfy two conditions. Forcibility: The compensating task of the task must be forcible. In other words, after the task commits, the execution of its compensating task is guaranteed to succeed by the application semantics. Relaxation of isolation: The isolation requirement of the shared data resources which the task may access must be relaxed. This relaxation is required as the purpose of introducing compensation is to avoid long-duration waiting, otherwise, compensation may become useless. In this work, we carefully investigate the properties of shared resources and tasks which may be performed on these resources. As all its invoked operations must be compensatable as well if a task is compensatable, we only discuss the compensatability of operations defined on shared resources.","PeriodicalId":236128,"journal":{"name":"Proceedings 15th International Conference on Data Engineering (Cat.
