Building a high-available architecture for distributed application was considered. This type of architecture model was set forth based on J2EE. According to the structure of J2EE, the application system for the whole enterprises was divided into three independent tiers: Web layer, EJB one and DB one. By applying different availability policies respectively to three layers, three different clustery, Web, EJB and DB clusters, were constituted, to form a 3-tier cluster system for improving the availability of the application system. The high-available performance of the system was analyzed and tested by virtue of Markov Random Process. The result showed that the model could improve the availability of J2EE system.
