In Network Information Service (NIS), whenever a change is made to map data, administrators run make to make corresponding changes to the NIS database. Typically, as a part of this process, make also propagates the changes to subordinate (slave) servers through yppush. This provides a way for administrators to push changes immediately to subordinate servers.
Because Server for NIS does not use make to make changes to the database, it provides an explicit yppush command to propagate changes to subordinate servers immediately. Server for NIS also provides a control in Services for UNIX Administration to push maps to subordinate NIS servers immediately.
Note that you use yppush to push changes only to subordinate NIS servers running on UNIX. Because Server for NIS uses Active Directory to store data, both master and subordinate servers share the same replicated Active Directory database. Changes to Active Directory are propagated to other Servers for NIS immediately. Thus, it is not necessary to use yppush to push changes to subordinate NIS servers.
For information about propagating maps immediately, see To propagate selected maps now and To propagate changed maps now.
For information about using yppush, see yppush.
