Integrated distributed application management under multi-ORB-vendor environment

A mechanism is proposed for managing distributed applications (DAPs) in environment having multiple object request brokers (ORBs). The mechanism ensures the normal-state functioning of DAPs composed of servers. It facilitates DAP management including fault, performance, and configuration management throughout the DAP lifecycle. The mechanism includes three kinds of key components. The first is a domain manager which is responsible for fault and configuration management of DAPs. The second is a server manager, which is responsible for fault and configuration management for servers that make up DAPs. The third is a monitor that manages the performance and normal/abnormal state of servers. The common interface for monitors functioning on different kinds of DAP platforms facilitates managing DAPs over multiple ORBs. The prototype of the proposed mechanism functions properly and performs well when used with a CORBA-2.0-compliant ORE.
