Routing Requests
In an environment with several ADU Servers, any method that accepts an ADUID routes the
request to another ADU Server if the ADU named is not local to the first server. ADUIDs contain
location data, so a server can identify which system owns each ADU.
Method Overview
The following is a brief description of the methods available for use with the ADU Server.
ADU.Assign Create a session with the ADU Server.
ADU.Create Create a new ADU.
ADU.Deassign Destroy a session with an ADU Server.
ADU.DeleteOneValue This is equivalent to DeleteValues with a single name.
ADU.DeleteSubTree DeleteOneValue on the given name and every name in the
subcontainer beneath it, cutting a branch from the tree a
container represents.
ADU.DeleteValues Given a list of names, this method removes from the ADU
the name and its value history, in effect making the ADU
smaller.
ADU.EventsIn Adds user-defined ADU events to an ADU.
ADU.Find Returns a list of ADUIDs that match a simple criterion.
ADU.FindByKey Finds one active local ADU based on a single search
criterion.
ADU.FindOrCreate Searches for a specified ADU and, if not found, creates the
ADU.
ADU.ForceTerminate Forces theADU object to be deleted from memory and
from the database both, so it can no longer be used.

ADU.GetActive Finds all the active ADUs at the time the call is made.
