Abstract

A transactional agent is a mobile agent which manipulates objects in one or more than one object server so as to satisfy some constraints. There are some types of constraints depending on applications. ACID is one of the constraints, which shows traditional atomic transactions. There are other constraints like at-least-one constraint where a transaction can commit if at least one object server is successfully manipulated. An agent leaves a surrogate agent on an object server on leaving the object server A surrogate holds objects manipulated by the agent and recreates an agent if the agent is faulty. In addition, an agent is replicated by itself. Thus, transactional agents are fault-tolerant. We discuss how transactional agents with types of commitment constraints can commit. We discuss how to implement transactional agents.
