Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] In order to realize the above-mentioned application server cluster and fault-tolerant technical content, the present invention divides the implementation into two parts, the EJB component client and the server-side implementation,

[0011] client:

[0012] First, the client sends a server call request through the client component interface agent; the client is responsible for the work of request forwarding. These tasks are specifically performed by the client agent (Stub) in the RMI system. The client Stub sends the business method call request from the client to any server replica node, and realizes fault tolerance by moving the actual call action up to its superclass. Then the request is forwarded by the client stub. The client stub must hold the server-side information, so the list view of the entire server group is synchronously maintained on eac...

Abstract

Under condition that JToneFrame application server cluster with multiple nodes does not stop service, using strategy of distributed load allocation, the disclosed method can realize following functions: loading and deleting node in cluster dynamically; supporting horizontal and vertical segmentation; balancing EJB container loads in object level and method level; cluster of supporting non state conversation Bean, state conversation Bean and entity Bean. In the invention, there is no possibility of single nonserviceable point; load divider is not self-existent, and load divider is as a module of each node. Thus, the invention solves issue of centeralization, and allocates requests to each node dispersedly.

Description

technical field [0001] The invention relates to an application server cluster and a fault-tolerant method, in particular to a method for improving the reliability of a component-based software system. Background technique [0002] The server-side Java platform (J2EE standard) has become the best way to provide Web information services. For mission-critical systems, reliability has become a major challenge for the Internet. Failures that directly impact critical business users or business partners are unacceptable. The infrastructure must be highly available to provide uninterrupted service to the business. [0003] In today's dynamic business environment, in order to meet demand, enterprises must have the ability to dynamically increase capacity. The infrastructure supporting such applications must be sufficiently scalable to allow near-linear expansion without changing software and hardware. Therefore, supporting clustering, load balancing and error recovery for the J2E...
