  1. Hands-on on Information System Antonio Fuentes Bermejo antonio.fuentes@rediris.es Oviedo, 20 de Noviembre de 2006

  2. lcg-infosites lcg-info Querying the Information System • In order to query directly the IS elements two high level tools are provided: • These tools should be enough for most common user needs and can be used to hide the complexity of raw LDAP queries.

  3. lcg-infosites This tool provides information related to Grid services: lcg-infosites --vo <your_vo> option –-is <your_bdii> • It’s mandatory to include the vo and the option • The --is option specifies the BDII you want to query If not supplied, the BDII defined into the environment variable LCG_GFAL_INFOSYS will be used

  4. lcg-infosites - options

  5. Initial Step • Please set the environment variable: • export LCG_GFAL_INFOSYS=grid004.ct.infn.it:2170

  6. Exercise 1 Obtaining information about CE

  10. Exercise 3 Listing the closeSE

  11. lcg-infosites - 3 lcg-infosites --vo gilda closeSE valor del bdii: mnto04.uniandes.edu.co:2170 Name of the CE: grid010.ct.infn.it:2119/jobmanager-lcgpbs-long aliserv6.ct.infn.it grid038.ct.infn.it Name of the CE: grid011f.cnaf.infn.it:2119/jobmanager-lcgpbs-long testbed005.cnaf.infn.it egee016.cnaf.infn.it Name of the CE: gilda03.lcca.usp.br:2119/jobmanager-lcgpbs-long gilda02.lcca.usp.br gilda02.lcca.usp.br Name of the CE: grid010.ct.infn.it:2119/jobmanager-lcgpbs-short aliserv6.ct.infn.it grid038.ct.infn.it

  12. Exercise 4 Obtaining information about software

  13. lcg-infosites - 4 lcg-infosites --vo gilda tag ************************************************************** Information for gilda relative to their software tags included in each CE ************************************************************** Name of the TAG: VO-gilda-GEANT Name of the TAG: VO-gilda-GKS05 Name of the CE:cn01.be.itu.edu.tr Name of the TAG: VO-gilda-slc3_ia32_gcc323 Name of the TAG: VO-gilda-CMKIN_5_1_1 Name of the TAG: VO-gilda-GEANT Name of the TAG: VO-gilda-GKS05 Name of the CE:grid010.ct.infn.it ....

  14. lcg-info • This tool allows the users to query, in a deeper way, the BDII • It requires the environment variable LCG_GFAL_INFOSYS to be set to the value of the BDII to be queried e.g. grid004.ct.infn.it:2170 • Prints the list of the CEs or SEs satisfying a given query along with a list of specified attributes.

  15. SINCE THE LATEST GLUE-SCHEMA UPDATE ONLY “=“ OPERATOR IS SUPPORTED! lcg-info • The query syntax is like this: attr1 op1 valueN, ... attrN opN valueN • where attrN is an attribute name • op is =, >= or <=, and the cuts are ANDed • A combination of attribute is supported • The cuts are comma-separated and spaces are not allowed

  16. lcg-info options

  17. Exercise 1 List all the attributes
