Choose a site that contains the database or Unity server you are configuring, and verify that the site has one or more GC directories.

  1. Choose a site that contains the Teradata Database you are configuring.
  2. Run the following commands to identify the GC servers for the site.
    dig +tcp -t SRV _ldap._tcp.site_name._sites.gc._msdcs.rootdomain.com

    where:

    Option Description
    site_name The name of a site that appears on the list of sites generated in step 2 of Finding the Available Sites in the Forest, and that is the location of the Teradata Database you are configuring.
    rootdomain The name of the super-domain for the GC found in Finding the Root Domain Name.

    The dig command returns output similar to:

    ; <<>> DiG 9.2.4 <<>> +tcp -t SRV _ldap._tcp.SanDiegoHQ._sites.gc._msdcs.rootdomain.com
