Information Service of Globus for DataGrid



Configuration of a country GIIS

The Globus host is the GIIS of a country or an institut.
We recommend to install the country GIIS on a machine without gatekeeper. This GIIS have to register itself to the CERN GIIS.
The CERN GIIS is the top level of GIIS DataGrid. The CERN GIIS is testbed001.cern.ch, port 2167.
Be careful, the GIIS patches should be apply.

You can find below the GIIS configuration files to modify after the Globus deploy.

In this example the GIIS is for the France (dc=fr, o=Grid) the name of the GIIS machine is marianne.in2p3.fr, the port number of France GIIS is 2137.
The country GIIS has no gatekeeper (the Globus specific line for gatekeeper in the /etc/inetd.conf is not request)

Operations to do :

  1. After the globus-local-deploy you have to modify/check this files :
    1. globus-daemons.conf
    2. grid-info-site-register.conf
    3. grid-info-site-slapd.conf
    4. grid-info-site.conf
    5. grid-info.conf
  2. Re-start Globus
  3. How to know if the GIIS functions correctly ?
    1. Verify the number of process alive
    2. When the country GIIS is correctly installed, THREE process are alive :
      TWO process grid-info-soft-register and ONE slapd process.

      # ps axw | grep grid-info

      31584 ? 0:00 sh /opt/globus/sbin/grid-info-soft-register -log /opt/globus/var/grid-info-system.log -f /opt/globus/etc/
      31602 ? S 0:00 sh /opt/globus/sbin/grid-info-soft-register -log /opt/globus/var/grid-info-system.log -f /opt/globus/etc/
      31711 ? S 0:01 /opt/globus/libexec/slapd -p 2137 -d 1 -f /opt/globus/etc/grid-info-in2p3-slapd.conf

    3. Browse the CERN GIIS
    4. Globus commande to browse the CERN GIIS :

      grid-info-search h testbed001.cern.ch p 2167 (objectclass=*) | more
      Later, you see the machines end the GIIS of your country

  4. Information Service logs
  5. All the logs of the Information Service are in the file :
    {deploy-dir}/var/grid-info-system.log

  6. Information Service cache
  7. All the cache files of the Information Service are in the directory :
    {deploy-dir}/var/

Configuration of a GIIS with a GRIS

The Globus host is the GIIS of a site.
This GIIS have to register itself to the country GIIS.
Be careful, the GIIS patches should be apply.

You can find below the GIIS configuration files to modify after the Globus deploy.

In this example the GIIS is for the site in2p3 (dc=in2p3, dc=fr, o=Grid) the name of the GIIS machine is mardg1.in2p3.fr, the port number of France GIIS is 2137.

Operations to do :

  1. After the globus-local-deploy you have to modify/check this files :
    1. globus-daemons.conf
    2. grid-info-site-register.conf
    3. grid-info-site-slapd.conf
    4. grid-info-ressource-register.conf
    5. grid-info-ressource-slapd.conf
    6. grid-info-site.conf
    7. grid-info.conf
  2. Re-start Globus
  3. How to know if the GIIS functions correctly ?
    1. Verify the number of process alive
    2. When the GIIS and the GRIS of the machine are correctly installed, SIX process are alive :
      FOUR process grid-info-soft-register and TWO slapd process.

      # ps axw | grep grid-info

      # For GIIS on port 2137
      31584 ? 0:00 sh /opt/globus/sbin/grid-info-soft-register -log /opt/globus/var/grid-info-system.log -f /opt/globus/etc/
      31602 ? S 0:00 sh /opt/globus/sbin/grid-info-soft-register -log /opt/globus/var/grid-info-system.log -f /opt/globus/etc/
      31711 ? S 0:01 /opt/globus/libexec/slapd -p 2137 -d 1 -f /opt/globus/etc/grid-info-in2p3-slapd.conf
      # For GRIS on port 2135
      31717 ? S 0:00 sh /opt/globus/sbin/grid-info-soft-register -log /opt/globus/var/grid-info-system.log -register -t mdsreg
      31734 ? S 0:00 /opt/globus/libexec/slapd -p 2135 -d 1 -f /opt/globus/etc/grid-info-resource-slapd.conf
      31740 ? S 0:01 sh /opt/globus/sbin/grid-info-soft-register -log /opt/globus/var/grid-info-system.log -register -t mdsreg

    3. Browse the country GIIS
    4. Globus commande to browse the country GIIS (example with the France GIIS) :

      grid-info-search h marianne.in2p3.fr p 2137 (objectclass=*) | more
      Later, you see the machines end the GIIS of your site

  4. Information Service logs
  5. All the logs of the Information Service are in the file :
    {deploy-dir}/var/grid-info-system.log

  6. Information Service cache
  7. All the cache files of the Information Service are in the directory :
    {deploy-dir}/var/
