J.Lauener, P.Charrue, P.Charrue* (CERN)
Within the CERN Controls middleware infrastructure the directory service plays the central role and is therefore considered to be a critical component. A complete middleware infrastructure is deployed and intensively used to access devices in all the accelerators complex. With the increase of the number of devices, new communication technologies and new demands in terms of management and statistics, a new Directory Service has been studied, developed and deployed in operation in December 2008. This presentation will describe the user requirements, the new directory service architecture, the enhancement implemented and its first results in operation.
