Monitoring Controls System meeting on May 28, 2002


Attendance:
Bill Badgett, Steve Hahn, Mark Knapp, Yeongdae Shon, Margherita Vittone, Marcin Wolter, John Yoh, JC Yun

NEWS:
Shutdown will start on June 3rd for 2 weeks as planned.

SYSTEM:
Steve said since virus scan priority was lowered, iFIX system functions much better - thanks to Chris Brew at the CD who found out the way to lower priority somehow. During the virus scan we used to see about 10 to 20 systmes went to gray on 'CDFGbAlarms' page. After the change we see ony about 2 systems went to gray.
Steve pointed out that the TOF takes about 2 times longer than other systems (~1hr) to complete virus scan. He thinks this has to do with 100% usage of CPU time. He said the CLC1 improved substantially since we cut down the cpu usage.
He also mentioned that someone accidentally killed the virus scan excutable in Muon3. We will restart it during the shutdown.
We also learned that turning off real time virus scan made little impact in performance.

VNODE:
Ace account time out (every 12 hr) problem caused a lot of trouble during the memorial weekend. It turned out someone thought it was operator and put in the time out limit. The Sunday morning power outage made things worse. We need a better instruction to recover from power outage. There are too many post-it stickers around the Vnode screens.

ICICLE:
Bill said a summer student ( Ravine Pierre ) is working on a software project. He will be writing a module which can store iFIX information into data stream. This will be very convenient for remote institutions.
Margherita is working to integrate the Muon Scintillators into the Icicle. She also mentioned that Icicle runs much more reliably since the virus scan priority has been lowered.

PSM:
Marcin removed the confusing check boxes and replaced them with small squares in the PSM pictures.

MUON:

  • Yeongdae's transpancies -
