This illustration contains four boxes labeled (from left to right) Node A, Node 1, Node 2, and Node 3. The Node A box contains three boxes, which are (from top to bottom), Admin Server, App Source and Patched Source. There is another box below the Node A box to represent the repository where the application source and patched application source reside (represented by App Source and Patched Source boxes). An arrow points from the Repository box to the Node A box to indicate that the Patched Source is copied from there to Node A. The Node 1 through Node 3 boxes each contain two Managed Server boxes with an App Source box under each Managed Server box. Arrows from the Admin Server in the Node A box to the App Source boxes in Nodes 1 through 3 indicate that the App Source is staged to those Nodes from the Admin Server Node A.
