Minutes 

Attendees: Dmitry A., Wayne B., Leve H., Jérôme L., Gene V.B., Jan B., Maxim N.

 

Online webserver:

  • Wayne installed: SSH key client, osiris
  • ITD backups nominally working
    • Warning message noted to ITD
    • Restore from backup (targeting machine with warning messages) by Wayne went fine
  • Synchronization with secondary new webserver done manually, not yet automatic
  • Tomcat restarted for Leve's scheduler statistics redeployment
    • Jerome's service idea should be copied from old server so that intentional downtimes don't trip the watcher

 

ShiftLog:

  • Detector checklist being posted to the ShiftLog regularly now. A suggestion from Jan to make it easier was to make a shortcut to the checklist document from the ShiftLeader's desktop (post-meeting Leve learned that each new checklist is given a new document name; finding the document isn't that difficult anyhow)

 

Online user support:

  • Enabling migration off sc.starp and onto linux pool
    • Dmitry notes that Corba libs are present on linux pool
    • Jan says Brian Page is in the midst of trying to move two components:
      • cdev reader (needs Corba libs, will try compiling)
      • DB writer (Gene will provide Brian with a working example code)
  • Two online disks (noted by Wayne in previous meetings): replaced
  • Some additional network issues this week
    • Initially fixed with a switch replacement
    • ...but addition failures occurred
    • Wayne will try to fix during access later today (post-meeting update: this went successfully; topic closed)
  • starutilities replacement: usage extension currently with "soft" limit
    • Matt could not install C-AD software in XP mode on new box
    • next possibility is dedicated XP machine (needs a software extension from ITD)
  • Other tasks (noted in previous meetings) in queue

 

Databases:

  • Shift sign-up un-subscriptions now exclude trainees [Dmitry]
  • Feedback to slow controls to implement monitoring of their automated services (are they running? is data flowing? for now, only Dmitry's dbPlots and an environment monitor)
  • TPC anode voltage migration was not running, but Dmitry will turn it on (we are aware of its shortcomings)
  • Dmitry noted RHIC clock seems to be variable even during fills (Gene will follow up)
  • Some discussion of when DB snapshots run; Jan seems OK with packaging at midnight for 4am usage for cloud jobs
  • Dmitry notes that there's an open discussion about recorded prescales being wrong. If this is corrected later in the DB, it shouldn't be a problem for offline users as long as they access from the DB and not from the DAQ files. Needs to be sorted out by trigger group first.

 

FastOffline:

  • Laser files were being skipped; fixed by Jerome
  • Automatic drift velocity calibrations started (and working)

 

QA:

  • OnlinePlots had 3 problems spurred by update of starnew to SL11a library
    • Macros used (Load.C) needed modified loading order of libraries (fixed)
    • Numerous histograms getting skipped, and others in unusual order in output PDFs (RT 2085)
      • Temporary solution: run in starpro (SL10k) patched for TOF/VPD updates
    • Code for inserting PDFs into database should use 'REPLACE INTO' instead of 'INSERT INTO', but we only have a binary of the current version
      • Dmitry had source code from an old version which Gene edited to work as desired now (update: codes committed to CVS)
  • Offline QA histogram filling needed to update code for TPC padrow determination
  • AutoCombining of offline histograms stopped working (Elizabeth investigating) (update: fixed for a changed function interface in QA daemon)
  • No references yet, but shift crew (Lanny) looking at data
    • Call for setting references will go out when physics readiness is achieved (many problems in current data)

Minutes 

Attendees: Dmitry A., Wayne B., Leve H., Jérôme L., Gene V.B.

 

Online webserver:

  • Went live on Monday
  • No user complaints reported
  • Jerome: identified and fixed several problems
  • Jerome: started tomcat watcher script (he noted that it already caught a number of trips)
  • Dmitry: though crontab had been copied, cron file entries had been missed
  • Wayne: to-do list:
    • Install SSH key client
    • Install osiris
    • Tomcat log file rotation
    • ITD backups (noted as priority)
    • Synchronization with secondary new webserver

ShiftLog:

  • 'thumbnailer' problem, Jerome is helping
  • MTD subsystem added by Leve
    • Used the opportunity to move the array of subsystems to a single place

 

Online user support:

  • sc.starp crashes (RT 2077)
    • Was repeatedly shutting down
    • Wayne: Box replaced (drive swapped), working fine...
    • ...but suspicion is UPS, battery replaced
    • Leave as is for now
    • Dmitry suggested providing Corba libs on online linux pool nodes to allow users an alternative to sc (Gene spoke with Jan B. about this post-meeting: Brian P. will try migrating his code)
  • Two online disks (noted by Wayne in previous meetings): still need replacement
  • QtRoot Event Display (RT 2075): Jerome notes it is low priority for now
  • HPSS access from online via data carousel: Jerome indicates work in progress for authentication (perhaps try replicating what was done with stargrid04)
  • starutilities replacement: extension through Jan. 30th.
    • trying to run C-AD software in XP mode on new box (Matt working with ITD today)
    • next possibility is dedicated XP machine
    • otherwise suggest software upgrade to C-AD (would require additional extension for procurement and delivery duration)
  • rts01 replacement machine (RT 2070): machine has arrived
  • Request for help restoring old FTPC event builders (RT 2066):
    • Wayne attempted to resurrect old builders but didn't succeed
    • Jeff has alternatives to move on
  • Conference room PC display configuration improved by Wayne, but may still be not optimal
  • FMS/Spin request for replacement machines (RT 2073 and 2074):
    • Laptop provided, and had to learn from experience to prevent power saver settings from shutting it down
    • Other machine not critical
  • Renewed request today for a folder on ShiftLeader's terminal for making files web-available (RT 2083)

 

Databases:

  • Migration macros started on onl01 by Dmitry
    • Machine died (from exhausted memory): cause is unknown, but perhaps one of the users
      • Table further investigation until it proves to be systematic
  • New DB node allocation for FatOffline(+nightly tests) awaits results of Lidia's tests
  • Dmitry noted that detector ID lists needed to be (and were) verified among Lidia, Tonko, and himself
    • Jerome noted that offline should rely on DB lookup by subsystem and not depend on a local list (he will follow up with Lidia)
  • Dmitry implemented flexible, graphical selection of timestamps for his online DB plots upon feedback from Alexei L.
    • Jerome tested on several OS-browser combinations

 

FastOffline:

  • Jerome notes that the chain needs continued attention (e.g. geometry, CA tracker), and Gene will take this

 

QA:

  • Some minor modifications made to OnlinePlots for VPD by Kefeng and Gene

Minutes 

Attendees: Dmitry A., Wayne B., Leve H., Jérôme L., Gene V.B.

 

ShiftLog [Leve]:

  • Checked that links work both ways with RunLog
  • Re-deployed to fix an issue with a function used to tell if we're in a shift-taking period
    • Dmitry suggested to modify this next year to not use dates

 

Online infrastructure [Wayne]:

  • New webserver:
    • Database access now working fine
    • Watcher script needs turned on
    • cron jobs (and associated files) need to be copied
    • Announcement for a Monday swap:
      • 2pm (Wayne, Jerome, Leve, Dmitry should be available to handle whatever may arise - Dmitry already knows one configuration he needs to change during the swap)
      • NFS will be turned off on the old server, sync will be done, IPs swapped, and NFS on.
  • Two online disks (noted last week) still need replacement
  • Event Display
    • Not currently functional (we lost our maintainer; Jerome is trying to prop it back up for now)
    • Pieces in multiple locations for online display plus offline (images dumped for web display)
    • Not critical (old online event display still functional), but valuable for PR
  • Long-standing request (not critical) to be able to read from HPSS online (via data carousel)
    • Jerome looking for any road blocks (e.g. firewall)
  • Machine replacements:
    • emcsc done
    • starutilities and ftpcgas not yet done (scheduled for work with relevant parties early next week)
  • All Windows nodes rebooted with security patches
  • rts01 replacement request merged into a larger purchase request (RT 2070)
  • Request for help restoring old FTPC event builders (RT 2066)
    • Possible solution of other hardware if this is too much effort
  • FMS/Spin request for replacement machines (RT 2073 and 2074). Not critical, but latter is important for remote access (current machine is inside WAH and not on network)

 

Databases [Dmitry]:

  • After new nodes go into production pool, 2 old nodes will be targeted for FastOffline + nightly tests
    • Assessment of new node speed/power still ongoing
  • onldb1 and 2 were up for 1+ years, so rebooted on purpose to check state
    • Collector daemons did not automatically start, but otherwise OK
    • Dmitry suggested leaving it this way since reboot need is so rare and automatic can take a while to get caught up (has to look through and skip all runs from the year)
    • Gene suggested making it automatic in case Dmitry's not around to restart daemons (though shift leaders can potentially do it themselves). We'll go with this.
  • QA files (OnlinePlots + Jevp) stored for RunLog can now exceed 4 GB without needing manual rollover
  • TPC Anode Voltges:
    • For now, continue with methods of collection from last year
    • Dmitry tested a supposedly-optimized "bulk reading" methods and found them to be no better than channel-by-channel (actually worse as it appears to be the same + overhead: 13-15 seconds to collect all values versus less than 1 second); dead end.
    • Possible new methods of collection under development (Tonko & the TPC group)
    • Feedback to the TPC group that wider "dead band zones" could reduce traffic and help alleviate problems due to load

 

FastOffline [Jerome]:

  • Same as last week: many files coming into the system, but all are tests, pulsers, etc., so not being processed
  • Gene notes some possible tweaks to the chain may be needed for TPC calibration status (awaiting TPC feedback)
  • Dmitry need to verify with Lidia some exported info from from onldb1

 

QA [Gene]:

  • Offline QA documentation updated (Lanny & Gene)
  • Jerome notes the need to monitor and document and issues with QA Shift
  • Pre-combining of FastOffline files still needs tested and configured to be the default
