      • CMS accesses the conditions data through frontier servers
      • Data volume at CMS is lower than the ATLAS one
    • LHCb:
      • Marco has run several tests and found and Oracle related problem when update several clob columns
      • Backport patch requested, tested, and will be scheduled on production
