CLUSTERED ENTERPRISE JAVA TM HAVING A MESSAGE PASSING KERNELIN A DISTRIBUTED PROCESSING SYSTEM

摘要

A clustered enterprise Java .TM. distributed processing system is provided. The distributed processing system includes a first and a second computer coupled to a communication medium. The first computer includ es a Java .TM. virtual machine (JVM) and kernel software layer for transferring messages, including a remote Java .TM. virtual machin e (RJVM). The second computer includes a JVM and a kernel software layer having a RJVM. Messages are passed from a RJVM to the JVM in one computer to the JVM and RJVM in the second computer. Messages may be forwarded through an intermediate server or rerout ed after a network reconfiguration. Each computer includes a Smart stub having a replica handler, including a load balancing software component and a failover software component. Each computer includes a duplicated service naming tree for storing a pool of Smart stubs at a node. The computers may be programmed in a stateless, stateless factory, or a stateful programming model. The clustered enterprise Java .TM. distributed processing system allows for enhanced scalability and fault tolerance.
