LHC machine - shutdown and 2011 startup plans

LHC restarts on Feb 21st. Roger's slides linked from the agenda contain the details.

End of year plans - service roundtable

CERN closure dates and service availability and support on best-effort basis are linked from the agenda. ALARM tickets should be opened when justified. Response time can't be expected to be at the usual levels. TEAM tickets should contain the relevant service managers in the GGUS ticket field Cc to make sure that, even if the CERN heldesk is closed.

Experiment issues

Database services

  • General news - upgrade:
    • Upgrading most production DBs to at the beginning of January (not changing the compatibility parameter - stays at!)

  • Site reports:
Site Status, recent changes, incidents, ... Planned interventions
ASGC   Upgrades to February 2011 (After Chinese New Year)
BNL Work with Zbyszek on the integration of new metric in the Tier 1 weekly reports (Sessions per day per domain / host).  
KIT   DB upgrade to in January 2011
NDGF We will follow CERN's recommendations regarding upgrade to and will plan the upgrade of our 3D database when we know about CERN's plans. If the ATLAS experiment does not need the conditions database at NDGF we might possibly shut down the database rather than spend time on upgrade to None
RAL Upgraded our pre-prod and certification castor DBs to Now waiting for CERN CASTOR to upgrade their DB to before we proceed with our production systems.  
SARA 3D DB migration to old hardware on the 14th of December canceled due to broken network switch  
TRIUMF On Dec 8 - upgraded our Oracle RAC storage firmware. DB upgrades to - by Feb 2011
