Method for reliability maintenance of distributed enterprise service bus node

Abstract

The invention relates to a method which can maintain the reliability of the service bus nodes of distributed enterprises. The method comprises the following steps: according to the node functions of the service bus nodes and the stored environment information, the nodes can be divided into four types: standard nodes, a host node, candidate nodes and proxy nodes; the extensible event mechanism is defined, when discovering that the environment changes in the service bus nodes, the nodes construct the corresponding event and inform the host node, so as to enable the information to be transmitted in the whole bus, and the important information in the bus can be copied through the candidate nodes in real time. The invention has the advantages that the normal operation of the bus can be ensured to the maximum extent under the condition that any node in the enterprise service bus fails, thereby reducing the influence to an enterprise information system; besides, after being recovered, the failure node reenters the bus environment and operates smoothly. A relative centralized information register center, namely the host node, is established; the event mechanism with the uniform interface is adopted.

Description

technical field [0001] The invention relates to a method for recovering from the collapse of distributed enterprise service bus nodes and a corresponding method for synchronizing information between nodes, and mainly relates to a reliability maintenance method for distributed enterprise service bus nodes. Background technique [0002] "Enterprise service bus", as the connection center of the application system, is a necessary element for building an enterprise information system based on SOA (Service Oriented Architecture, service-oriented architecture). The definition of enterprise service bus can be simply understood as: a set of infrastructures implemented by middleware technology and supporting SOA, supporting services, messages and event-based interactions in heterogeneous environments, and having appropriate service levels and manageability . Through the enterprise service bus, the application system can be quickly connected, and through the more advanced event and pr...

Problems solved by technology

The central-spoke mode registers all services in a unified central "hub", that is, all service messages need to pass through a central server. Although this method is relatively easy to deploy and manage, its disadvantages are also obvious. The performance of enterprise information systems It will be subject to the message transfer capability of the central server. When the central server fails, the function of the entire enterprise information system will be greatly affected
