GOAL:
What are Progress NameServer Neighbors
FACT(s) (Environment):
Progress 9.x
OpenEdge 10.x
All Supported Operating Systems
FIX:
NameServer neighbors refers to a configuration of multiple NameServers on machines located in one or more subnets.
In this configuration, an initial NameServer instance receives the client connection request. If this initial NameServer cannot resolve the request, it passes the request on to a specified list of NameServer Neighbors.
These NameServer neighbors then attempt to resolve the connection request.
Each NameServer neighbor represents the controlling NameServer for a separate unified broker instance.
Use NameServer neighbors where replicated NameServers are needed for fault tolerance and the replicas need to span a subnet if UDP Protocol broadcast is not allowed by the hardware used or the policies defined within a network environment.
The way the control works for the neighboring NameServer is not intuitive.
The list of NameServers in the control is the list of NameServers defined at the site.
It is not the list of Neighboring NameServers.
