Delegation mechanism in agent-oriented framework for managing long-lived transaction

The paper addresses the long-lived transaction management paradigm based on workflows with a view to evaluating the un-executable works. In our 3-layer transaction model, each long-lived transaction is divided into several transactions, which are organized as workflows. Additionally, the model is applied by agent orientation to attain the flexible control mechanism. Three different kinds of agents are located at each layer in this model: manager, executor and actor. The manager manages long-lived transactions globally and controls executors; the executor manages each transaction locally and controls actors; and the actor executes atomic tasks individually. The delegation mechanism discussed mainly in the paper is supported by related managers, with a view to evaluating the work which one manager cannot manipulate in a timely or accidental manner.
