Release 10.1A: OpenEdge Getting Started:
Application and Integration Services

NameServer

The NameServer is a process that maintains a list of WebSpeed Transaction Servers. It is called by the WebSpeed Messenger in response to a client request.

Transaction servers register with the NameServer and inform the NameServer about the application services they provide . The NameServer can then direct client connection requests to a Transaction server that supports a requested application service. This provides scalability and location transparency to your applications.

Use of the NameServer is optional. However, without a NameServer a Messenger can only connect to a single Transaction server.
