3. E-infrastructure shared between Europe and Latin America 4th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS - Mexico DF, 28/08-01/09,2006 3 Information System Overview The Information System (IS) provides information about grid resources and their actual status. Computing and Storage resources at a site report their static and dynamic status information via GRISes (Grid Resource Information Server) –one per grid element At each site an element called GIIS (Grid Index Information Server) collects information from all the site GRISes –one per grid site The BDII (Berkley Database Information Index) queries the GIISes (of different sites) and acts as a cache storing information about the Grid status in its database.

4. E-infrastructure shared between Europe and Latin America 4th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS - Mexico DF, 28/08-01/09,2006 4 BDII Users and other Grid services (such as the RB) can query BDIIs to get information about the Grid status. Each BDII collects information from the site GIISes (or local BDII) defined in a configuration file, which is accessed through a web interfaces. Every two minutes a cron-job runs a script and collects information (pull model) from all the GIISes (local BDII) listed in the configuration file.

7. E-infrastructure shared between Europe and Latin America 4th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS - Mexico DF, 28/08-01/09,2006 7 my-site-info.def customization Copy /opt/glite/yaim/examples/gilda_ig-site-info.def into /root/my-site-info.def and edit these fields: MY_DOMAIN=super.unam.mx CE_HOST=gilda-ce.eela.if.ufrj.br WMS_HOST=eela-138.super.unam.mx BDII_HOST=eela-XXX.super.unam.mx MON_HOST=rgmasrv.ct.infn.it FTS_HOST=fts.ct.infn.it NTP_HOSTS_IP=193.206.144.10

8. E-infrastructure shared between Europe and Latin America 4th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS - Mexico DF, 28/08-01/09,2006 8 Middleware installation with YAIM We are ready to install the BDII Server: /opt/glite/bin/gilda_ig_install_node /root/my-site-info.def GILDA_ig_BDII This command will download and install all the needed packages. Now we can configure the node: /opt/glite/bin/gilda_ig_configure_node /root/my-site-info.def GILDA_ig_BDII

9. E-infrastructure shared between Europe and Latin America 4th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS - Mexico DF, 28/08-01/09,2006 9 Firewall configuration Be sure that your firewall is open for bdii listening port (2170). By instance on /etc/sysconfig/iptables add: -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 2170 -j ACCEPT service iptables restart

11. E-infrastructure shared between Europe and Latin America 4th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS - Mexico DF, 28/08-01/09,2006 11 BDII testing Issue an ldapsearch to check if BDII is correctly publishing sites informations: – ldapsearch -x -h -p 2170 -b 'mds-vo- name=local,o=grid‘ Or Use LDAP Browser to test your BDII. You can download it from: – http://www-unix.mcs.anl.gov/~gawor/ldap/index.html http://www-unix.mcs.anl.gov/~gawor/ldap/index.html Or Log into a LCG User Interface machine and use lcg- infosites: – export LCG_GFAL_INFOSYS= :2170 – lcg-infosites --vo gilda ce
