| 摘 要： | 就面向服务的分布式系统中多服务动态更新的协调问题,提出基于事务控制的更新协调策略,包括安全更新时机的选择策略、使用2PC(two-phase-commit)协调多服务更新的控制策略.根据更新实施的各步操作时间开销,提出分别采用更新短事务控制基本更新操作(包括创建服务实例、顺序实施运行时状态转换、重定向服务请求和新服务的...

| Abstract: | This paper presents a group of strategies based on transaction mechanism for the coordination of the multi-services' dynamic updating in a service-oriented distributed system.These strategies included a selection strategy for choosing of security updating time-point and a 2PC(two-phase-commit) strategy for controlling the multi-services' updating.With the analysis of time,needed by related updating operation steps,this paper suggests that the basic updating operations(including creation of service instances... |
