  • Gancho (online-offline ATLAS tests): got appropieate accounts, running first tests (tables creation and data population), preparing job to introduce big load on the server
  • Stefan: exercising the load of COOL database from different locations. Dirk suggest to start the replication tests asap (contact Gordon or Eva for help)
  • Jerome and Eva are in contact for testing AMI database replication
  • Marco: no more tests so far

  • Summary
    • provides one interfarce for the user and the appropiate channels to forward the problems to specific experts
    • how to contact the user whose jobs are misconfigured? people behind support lists will look at the user causing the problem,...
    • applications are not really interface: the request is forwarded to the Generic Grid experts and, in case of the applications, they forwarded the request to the special unit of the application
