May 20, 2009 online meeting minutes

present: Sergey Boyarinov, Sergey Pozdnyakov

1. HV

one of the TOF Lecroy mainframes was replaced by TOF team, spare was takes from the counting house; will not send broken Lecroy mainframe to repair yet to save money, upgrade needed and it will cost about $7000; 3 boards were moved from the hall to the test setup, 2 of them seems fine (one of them had tilted pin in bus connector); need better organized HV repair procedure, last time 4 boards were broken in a process in counting house test setup, need a meeting with all personal involved

glued patch panels seems working fine, will use that method in future; 2 channels in 2 A1535 boards were broken and will be repaired; will ask Chris to repair and check calibration; if calibration is bad then will send it to CAEN; third board (unvisible in mainframe) will be stripped, and then send to CAEN

2. DAQ:

polar readout was changed, scaler opens in first event now (was in Go), does not crash on first event any more

it was observed that if ROCs running for the long time (week and more) they must be rebooted, otherwise they starting to crash one after another, need to understand the reason; in a meanwhile will run 'net' only on PMCs, will see if it cost by 'net' or 'proc'

disconnected front-end-busy cable from SF to FC was disconnected on the floor, it cost missing gate errors in DC crates; cable was labeled and connected

'mysql not available' error was observed in runcontrol, also all rocs reboot sometimes cost database to not respond fast enough, need to investigate

3. Run database

run_log_restore program is ready, it will restore 3 ascii files in $CLON_PARMS area, which will be used to update database; will create a cron job to extract files from SILO and scan them one by one; 2 copies will be run: on clondaq2 to restore new files from raid, and on clonmon1 to restore old files from SILO
