Problems solved by technology

[0005] Most of the existing products support reliable transport protocols at the message layer to support reliable invocation of services, but the service layer does not support service error handling enough. When an error occurs during request processing, the error message is returned to the user or simple The retry operation cannot flexibly configure the error detection method and error recovery method, so that it can guarantee the reliable invocation of services in complex and unreliable network environments

Embodiment Construction

[0017] Such as figure 1 As shown, the intermediary layer of the present invention recovers errors by retrying and invoking equivalent services when a service call fails, and can configure service fault tolerance policies. Service fault tolerance is divided into fault tolerance strategy, error detection, error recovery and error handler.

[0018] The fault-tolerance policy defines how errors are detected and handled by the service. The fault tolerance policy defines the error classification, and configures the correspondence between error detection and error handling. Each error detector will specify an error number when it triggers an error, and each error handler is also configured with the error number it handles. After the error detector triggers an error, the fault tolerance strategy finds a matching error handler for processing according to the error number. Users can flexibly configure fault-tolerant policies according to requirements, and the system automatically star...

Abstract

The present invention provides a service agency layer fault-tolerant method based on XESB. The agency layer adopts politic service fault-tolerant modus to recovery the wrong when service transfer is failure. XESB agency layer is divided into three part error detection, error recovery and fault-tolerant policy by adopting politic service fault-tolerant mechanism. Error detector testing system wrong, error recovery module executing recovery when having wrong, fault-tolerant policy defining detection mode of wrong and correspond relationship between wrong processors. retry mechanism, equivalence service transfer mechanism and multiple service transfer mechanism are provided for executing recovery processing to wrong when service transfer generates wrong. The present invention ensure reliability of service, improving error detection, reuse of fault tolerant component and flexibility of error handling modus.

Description

technical field [0001] The invention relates to an XESB-based service intermediary layer fault tolerance method, which is mainly used in the XESB service fault tolerance. Background technique [0002] With the enhancement of the advantages of the Internet, more and more enterprises provide Internet-based services, new business models have been developed, and the interaction between enterprise business systems has gradually increased, and communication and integration problems between systems have emerged. There are also integration problems between heterogeneous systems within the enterprise. The original development tools and platforms cannot meet the needs of building distributed systems. In order to reuse existing systems and reduce IT system investment, various distributed component technologies have been developed, such as CORBA technology organized by OMG, RMI technology of the Java camp, Microsoft DCOM technology. These technologies can solve the communication and i...
