大规模事务处理系统中服务对象监测的实现

Implementation of service object monitoring in large scale transaction processing system

针对在大规事务处理系统中对冗余服务对象的有效性和运行状态的监测要求,为提高该系统中服务对象监测的效率,利用通用对象请求代理框架提供的请求级截获器技术,实现了系统对象检测。通过选择适当的截获点,构建了实现服务对象监测所需的类、接口和相关操作,并确立了详细的对象状态监测与分析操作流程。当截获器截获到请求时,使用了推模式将信息传递到对象服务代理。在实验系统中的运行结果表明,本设计能实现对系统中服务对象的高效监测,能保证大规模事务处理系统的高可用性和服务质量。

Aiming at the requirement of system monitoring on validity of redundant service object and running state in large scale transaction processing system, in order to promote the efficiency in monitoring system service object, system service object monitoring is implemented by taking use of interceptor on request level, which is defined by CORBA （common object request broker architecture）. After selecting proper intercepting entry, the interface and related operation to realize the function of server object monitoring is constructed. Also, the processing flow of object state monitoring and analysis is set up in detail. When interceptor captures a request, pushing mode is used to transfer the information to object server agent （SA）. After running in experimental system, results show that this design is able to implement system service monitoring in high efficiency, and ensure the high usability and service quality in large scale transaction system.
