OSF DCE Research Articles

The rural and global medical informatics consortium and network for radiology services

Telemedicine systems that provide health delivery services to rural clinics and hospitals are being demonstrated in clinical settings. This paper summarizes the research and consortia projects at the University of Arizona Medical Center. The paper describes the Rural and Global Picture Archiving and Communications (PACS) environment developed under a National Science Foundation grant. The Rural and Global PACS environment includes many workstations, database, and networking components and is treated as a large distributed system. These components are described in this paper. The multimedia services for radiology provided by the Rural and Global PACS are described and their performance is measured. Finally, the current research work using the Open Software Foundation's distributed computing environment (OSF DCE) services is described. An OSF DCE testbed for the Rural and Global PACS is described and the rationale of using OSF DCE in the project is presented.

Open DECdtm

Open DECdtm offers portable transaction management services layered on OSF DCE which support the application (TX), resource manager (XA), and transactional DCE RPC (TxRPC) interfaces specified by X/Open. Open DECdtm also provides interoperability with OSI Transaction Processing (OSI TP) and OpenVMS systems using the DECdtm OpenVMS protocol. Protocols executed by Open DECdtm are specified by constraints. This simplifies the development of transactional gateways between different data transfer protocols and transaction models.
