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 ltyour_vogt option -is
  ltyour_bdiigt
• Its 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

lcg-infosites - options
5
Initial Step

• Please set the environment variable
• export LCG_GFAL_INFOSYSgrid004.ct.infn.it2170

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.it2170
• Prints the list of the CEs or SEs satisfying a
  given query along with a list of specified
  attributes.

15
lcg-info

• The query syntax is like this
• attr1 op1 valueN, ... attrN opN valueN
• where attrN is an attribute name
• op is , gt or lt, and the cuts are ANDed
• A combination of attribute is supported
• The cuts are comma-separated and spaces are not
  allowed
