  Testbed site needs from this experience

General comment Up to now it has been quite
hard for a remote site to follow the Testbed1
evolution from those sources We are shooting
on a moving target (F. Gagliardi)

TB info sources EDG Install Guide

• The EDG Installation Guide
• Main source of information
• It is an evolving document (current from
  3/02/2002)
• It is condemned to be incomplete
• http//www.pi.infn.it/flavia/se_config.html
• http//www.lnl.infn.it/datagrid/wp4-install/testbe
  d-report_2/index.html
• Sometimes the info is a bit confusing or
  inconsistent w.r.t. other WPs docs
• E.g. Configuration of the CE SE Info Systems

  and GRIS

• For the parameters inside globus.conf
• From WP3 Web (http//hepwww.rl.ac.uk/DataGridMonit
  oring)
• GRID_INFO_GRIS_REG_GIISral - The site name

TB info sources Bugzilla mailing list

• Bugzilla (http//marianne.in2p3.fr/datagrid/bugzil
  la)
• Keeps record of s/w features/bugs
• Information about which are the open/closed
  problems at a given moment
• Searchable Clear classification in terms of
  programs (GDMP, LCFG) and versions
• New category Testbed configuration added on mid
  December
• This might be the best info repository for site
  admin issues
• Still, some information here is not totally up to
  date

14
TB info sources Bugzilla mailing list

• The ITeam mailing list
• www.listbox.cern.ch/earchive/hep-proj-grid-integra
  tion-team/
• This is the ultimate source of truly real-time
  information concerning TB1 installation issues
• E.g. Replica Catalog installation instructions,
  SE/GDMP configuration issues
• The throughput is high enough (102 mails/day) to
  make online reading/filtering a tough task
• Searchable But not as good as bugzilla to search
  for all those problems related to a given
  service

15
MapCenter

• Online information about LDAP based Information
  Systems
• User friendly browsable

16
More info sources WP6 secure Web

• http//marianne.in2p3.fr/
• Extensive info on real
• TB machines config.
• rpm -qa/ps -ef output
• .conf files

More info sources National WP6 Web sites

• All them accessible from marianne.in2p3.fr
• Several (Dutchgrid, Nordugrid, GridPP,) include
  useful information on the EDG s/w installation
  configuration
• Step-by-step instructions for installing services
• Comments on the official installation
  procedures
• Some really fancy monitoring information

More info sources MDS monitoring

• MDS single-host response times from dutchgrid.nl

Summary (what we need/have from WP6?)

• Bugzilla Testbed Configuration category
• Site administrators mailing list
• WP7 monitoring tools such as MapCenter
• Configuration of some reference machines
  (CERN?) available from a secure Web site
• EDG Installation Guide collect all the useful
  information that is dispersed
• Useful info on national WP6 web sites (tools,
  step-by-step installations) could be compiled
  somewhere
• Planning schedule for widespread TB deployment
  to remote sites
