Connecting to a Database Using a Server Connection Definition
A Server Connection Definition defines the connection information for a database on a different server (a remote database). A Server Connection Definition is also known as a virtual node, or vnode.
Director itself cannot connect to a remote installation using a Server Connection Definition because it connects through a different protocol to do remote management. Server Connection Definitions, however, can be used with OpenROAD, other Actian query tools, or user-written Embedded SQL programs.
