The menu optinos allow you to query database information for a single PDBI database entry, or for a range of the same type of PDBI database entries, on an available server. For example, you can query a specified server for information about a range of DNs.
Querying a server for PDBI data allows you to see if data is being replicated correctly to each server, and allows you to see if adjustments to data management or to the subscriber database need to be made.
