摘要:
为了实现组合服务对异常情况的自适应,提出了一种组合服务动态调整机制.该机制将调整逻辑和BPEL执行逻辑相分离,从而能够在不扩展BPEL语言的语法和语义基础上支持组合服务的动态调整,保证了方法的适用性.建立了服务异常模型来描述服务运行过程中所面临的异常情况的类别、产生原因以及外在表现,并且在该模型的基础上给出了异常监控策略.提出了组合服务替换范围确定算法和调整方案生成启发式算法,保证了组合服务动态调整的效率.系统实现和实验验证了提出的组合服务动态调整方法的有效性.
Abstract:
In order to implement the self-adaptation of composite services in exception occurrence, a mechanism of dynamic adjustment is proposed. By separating the adjustment logic from the BPEL execution logic, this mechanism can support dynamic adjustment without extension of syntax and semantic of the BPEL language. The mechanism can preserve the applicability of the execution engine. The service exception model is established to describe the type, reason and the external feature of the exceptions incurred in the execution. Based on this model, the policy for monitoring the exception is given. The algorithm for determining the substitution scope of the composite service and the heuristic algorithm for the generating adjustment plan are proposed, which can insure the efficiency of the dynamic adjustment of the composite services. The system implementation and experiments verify the effectiveness of the proposed method.
