CLUSTERED ENTERPRISE JAVA TM HAVING A MESSAGE PASSING KERNEL IN A DISTRIBUTED PROCESSING SYSTEM

摘要

A clustered enterprise Java .TM. distributed processing system is provided.The distributed processing system includes a first and asecond computer coupled to a communication medium. The first computer includesa Java .TM. virtual machine (JVM) and kernel softwarelayer for transferring messages, including a remote Java .TM. virtual machine(RJVM). The second computer includes a JVM and a kernelsoftware layer having a RJVM. Messages are passed from a RJVM to the JVM inone computer to the JVM and RJVM in the secondcomputer. Messages may be forwarded through an intermediate server or reroutedafter a network reconfiguration. Each computer includesa Smart stub having a replica handler, including a load balancing softwarecomponent and a failover software component. Each computerincludes a duplicated service naming tree for storing a pool of Smart stubs ata node. The computers may be programmed in a stateless,stateless factory, or a stateful programming model. The clustered enterpriseJava .TM. distributed processing system allows for enhancedscalability and fault tolerance.
