  But a GEOC has also to be an expert shifter: (s)he has to give hints and helps to the production shifters, and know how to approach production and users problems. Also, (s)he has to be able to do simple DIRAC-related operations, like restarting a service which is stuck.

Grid Shifters are responsible for flagging issues with the ongoing activities in the Production system and directing reports to the Grid Expert on duty. Grid Experts on duty can make a first pass at solving the reported problems or delegate tasks to the relevant member of the Grid Team (or DIRAC developers) as necessary. Grid Experts are responsible for various tasks relating to the daily functioning of the Production system, each has the duty to document procedures pertaining to these tasks as necessary such that other Grid Experts and Shifters can make a first pass to resolve known problems. Grid Experts are ʻon callʼ in order to provide a point of contact for the Grid Shifters.

While ʻon callʼ the Grid Expert should remain in close contact with the shifter during office hours e.g. being in the control room. Outside of office hours the on call Grid Expert should be reachable via mobile phone in case of emergencies. Each member of the Grid team will have at least a primary and secondary role of expertise to ensure that all activities are covered in case of absence. When ʻon callʼ a Grid Expert can delegate their duties to backup members of the Grid Team if necessary.

Daily meetings

Line: 31 to 26
 
  • The daily operations meeting starts every working day at 11:15 (CERN time) in the LHCb offline control room (2-R 014), but there are cases where such a meeting could be cancelled: when there is no real data taking, and there is nothing urgent to be discussed. An indico meeting should be set up by the GEOC, usually cloning the former meeting. The minutes have to be then put in the minutes of daily meeting ELOG.

  Since in LCG, a problem is not a problem if there is no GGUS ticket is opened, this report has to include a reference to the newly opened ticket, and news (or request for news) for the older ones have to be briefly discussed within this meeting.
