MOTIVATION Recent years have witnessed the emergence of autonomic management tools in large scale information systems. They utilize the knowledge learned from system experts or historical data to automate the process of management tasks. However, current autonomic solutions only focus on the knowledge discovery and modeling to bene t the management in the same system. It is sometimes also important to utilize the knowledge of one system to facilitate the management of other systems. For example, a lot of special kinds of systems, such as the online banking systems, usually run on similar platforms, i.e., the J2EE based infrastructure, to support applications with similar business logics. If we can learn the behavior of one system and transfer the learned knowledge to other similar systems, it is not necessary to spend the same amount of
