  2. Querying the Information System lcg-infosites lcg-info • 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. Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  3. lcg-infosites - 1 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. List of options: Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  4. Exercise 1 Obtaining information about CE Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  10. lcg-info SINCE THE LATEST GLUE-SCHEMA UPDATE ONLY “=“ OPERATOR IS SUPPORTED! • This program allows the user to query, in a deeper way, the BDII. It requires the environmental variable LCG_GFAL_INFOSYS to be set to the value of the BDII to be queried, e.g. eelatut04.eela.if.ufrj.br:2170 • Prints the list of the CEs or SEs satisfying a given query along with a list of specified attributes. • 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.
