  5. UIM UIM UIM DCS Ctrl API operator Full scale: ~ 25 PVSS systems on >100 computers A typical system has 40 000 parameters to control - each with alarm possibility PVSS scalability and Alarm handling are critical issues !

  6. PVSS progress • New version released (December 03) • Better performance & robustness • Handling of distributed systems improved • Oracle archiving delayed to ‘August 04 release’ • Scalability • CERN tests: 130 PVSS systems on 15 computers • Static functionality ok; Dynamic behavior yet to be tested • LOFAR project test: 115 producer to 5 consumer PVSS systems • Scales well; ~700 ups/station measured • Alarm avalanches • 2 PVSS systems on 2 computers provoking 10000 alarms on each system • Result satisfactory

DCS Back-end

  8. 2. Detectors • Requirements • Detector URD’s have been completed to ~75% • Prototyping • All main detectors have started prototyping their sub-systems • ~10 prototypes implemented and working with PVSS • Common solutions • High Voltage & Low Voltage • Device drivers have been prototyped for most common devices • State machine behavior has been developed; being standardized • Front End Electronics • Generic device model (FED) has been defined and prototyped • A global configuration scheme has been defined and is being prototyped • General Purpose Monitor • A prototype solution has been developed • TPC, HMPID and SPD used as test case
