Release 10.1A: OpenEdge Application Server:
Developing AppServer Applications

> ## Network deployment considerations

> As you plan your overall deployment strategy, keep in mind that the AppServer supports only:

> - Transport Control Protocol/Internet Protocol (TCP/IP) for client access to the AppServer.

> - Universal Datagram Protocol (UDP) for client (and AppServer) access to the NameServer.

> However, an AppServer agent, like any Progress 4GL client session, can communicate with databases and DataServers using TCP/IP or SNA.

> If you have to connect the AppServer to a DataServer to access a non-OpenEdge database (and possibly through another network protocol), do the following:

> - Use the appropriate OpenEdge DataServer.

> - Use the OpenEdge OEBuild utility to create a customized AppServer agent executable if the appropriate DataServer is not already built into the client.

> For more information on building an AppServer agent executable, see the sections on building OpenEdge executables in OpenEdge Deployment: Managing 4GL Applications .
