Description

   LICENSE UNLOAD affects all units for a single product even if
   the loaded units are combined from multiple licenses. In such a
   case, you cannot unload the units from a single license. You must
   unload all the units.

   You are not required to unload a loaded license before modifying
   data in the License Database. To maximize product availability,
   modify licenses in the License Database first, and then load
   the changes by entering a LICENSE UNLOAD command followed by a
   LICENSE LOAD command.
