Cluster Support Workflow Management System Cluster-synchroflow, Design And Implementation

WFMS is designated as the fourth detached revolution of information management system , it belongs to middleware category, it provides a rapid developping , deploying and running platform . WFMS can integrate a corporation' s inside business and outside business seamlessly, it is widely used in e business, concurrent office, human resource alteration credit auditing, all kinds of application , custom domain, and other many practices domains. The use of WFMS obviously enhances the flexible quality of application system, quicken application developping cycle and reduce the developping cost.But, the workflow engine services, the kernel of WFMS have some hidden trouble, such as service interrupted by natural reasons or other reasons and service performance reduced caused by all kinds of reasons. These problem will caused huge loss. Another question must be paid attention , The WfMC organization only put forward a abstract reference model. So, the material implementing of the workflow management products in the market differ form each other.Aiming at these problems, this paper choice the workflow management system, Synchroflow, as the practice system, and use cluster to support it. Finally this paper realizes two systems, they are Synchroflow based on high available cluster(HACluster- Synchroflow 1. 0) and Synchroflow based on high performance cluster (HPCluster-Synchroflow 1.0). Compare to the original system , the new systems have friendly and convenient interface, the users can request the workflow service transparently.Through putting the systems in use, and getting the safe and satisfied results, testify the research' s feasibility and validity.
