  1. OASIS: Status Report S. Deghaye, L. Bojtar, Y. Georgievskiy, J. Serrano. CERN, Geneva, Switzerland. ICALEPCS'05

  2. Overview • What is OASIS? • How is it done? • Fast communication scheme • Deployment & user feedback ICALEPCS'05

  3. What is OASIS ? Oscilloscopes (VXI & CompactPCI) Multiplexing Matrices (VXI & CompactPCI) Trigger counters (VXI & VME) Typ. 500 pts ICALEPCS'05

  4. GUI Thin client Graphic & user interaction OASIS Viewer RMI/IIOP (synchronous calls) JMS (asynchronous calls) Complete view on the system Connection & setting management VScope impl. Session beans Message-driven beans Entity beans (persistence) OASIS Application Server OC4J Java API for Parameter Control (JAPC) Hw control Hw independent interface (See P-2.090) Controls MiddleWare (CMW) OASIS Front-End tier Front-End Software Architecture (FESA) Device drivers Hardware CompactPCI & VXI OASIS Architecture ICALEPCS'05

  7. Septembre 2003 •  6 signals •  2 digitisers • April 2005 •  200+ signals •  3 digitiser crates •  1 trigger crate • Septembre 2004 •  14 signals •  6 digitisers Deployment ICALEPCS'05

  8. User Feedback • Tight synchronisation on client side. • Development of a Trigger Logic. • Entity beans slower than expected. • Tuning needed. ICALEPCS'05

  9. Summary • OASIS available and in production • 3-tier architecture suits well OASIS • For higher performance  2-tier communication scheme ICALEPCS'05

  10. Questions ? ICALEPCS'05
