摘要:
首先简要介绍并分析了CORBA2.4.2规范中有关可移植对象适配器POA的主要内容,然后着重介绍了东南大学计算机系网络室自行开发的JORBUS系统中的POA的实现模型及其特点,该模型将POA的功能分成状态控制、请求接收、策略管理、Servant管理、调用请求管理等几大部分,并分别使用相关部件来完成,使得POA结构清晰明了.文章最后介绍了该系统对POA进行的优化工作,包括在线程池和进程内调用两个方面进行优化的必要性、相关问题和解决措施,还分别通过测试,显示优化取得的良好效果.
Abstract:
An introduction to the main content of Portable Object Adaptor in CORBA 2.4.2 specification is presented and the model of the POA in Southeast University’s JORBUS system and its features are introduced in detail. This model partitions the POA functions into several parts, including state-control, request receiving, policies managing, servant managing, and invocation managing, etc, and uses corresponding components to implement them. At last the optimization work in JORBUS POA by using thread pool and improving invocation course in the same process is introduced. The tests given show that these optimization works gain well effect.
