In this paper, we develop an integrated management/monitoring system that supports to dynamically reconfigure information models for systems or applications managed by heterogeneous distributed systems. When the subsystems on diverse platforms are added, removed, or modified, the altered configurations should conform to the configuration information of the integrated management/monitoring system. Further, upon the system configurations being changed, the altered system configurations should be synchronized with the information on the integrated management/monitoring system. Moreover, availability should be assured during synchronization to the extent that users can access the monitoring information with no system halting. This paper focuses on notifying the integrated management/monitoring system of any changes in hardware/software configurations on any subsystems under its management, and on dynamically re-configuring the information about hardware and software being managed based on the information notified. Finally, we expect that this research will be contributory to carrying out reliable integrated management by reflecting the information on any heterogeneous distributed systems in the integrated management/monitoring system.
Recently Web services and SOA(Service Oriented Architecture) is widely used for an effective integration way of distributed applications. The service choreography is a way of service compositions to define workflows and the message exchange protocols among several partner services in the B2B business process environment. It defines the overall business process from a global perspective. However, it must be transformed into some kind of the executable form to implement service compositions, because it does not support an execution mechanism but is a declarative form. Therefore, the transformed executable model must be validated with the original choreography model to guarantee behavior equivalence. In this paper, we propose the conformity assessment with respect to service compositions method between the choreography model and the transformed executable model. And we suggest the test method to show behavior equivalence between them from a viewpoint of the dynamic execution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
