What actions are performed by the command dacontrol -i <installation_name>?
The dacontrol command searches for the specified installation name by opening a CAPI session with the adclient. Through the session, dacontrol performs an LDAP search looking for the SCP's for the specified installation name, the goal is to retrieve the information about the installation.
Once a CAPI session is established with the adclient, then dacontrol will perform an LDAP search with the GC (global catalog) first. If it fails, it will try searching through the rest of the joined domain. The adclient, when it receives the CAPI call, will use the currently selected GC/DC to perform an LDAP search. Whichever GC/DC the adclient is currently bound to when receiving the call, will be used to perform the search.
Normally adclient already has the DC/GC selected prior to receiving the CAPI calls. After the search is complete, it knows the important information of the installation such as collectors, installation name, etc. The dacontrol is now finished.
