Configuring TN Server

Configuring TN Server

TN server enables TN3270 clients to communicate with a host through an intermediate SNAplus2 node that implements the TN server. The TN3270 clients connect to the TN server using TCP/IP, and use LUs defined on the TN server. The TN server LUs establish sessions with LUs at the host to support TN3270 sessions for the clients.

Before you can configure TN server, you must perform the following configuration tasks:

•Define the local node as described in “Configuring the Node”.

•Configure a port and link station for dependent traffic between the local node and the host, as described in Chapter 5, “Defining Connectivity Components.”

•Define the TN3270 LUs on the local node that are used for communication with the host. To add the LUs, see “Defining LU Types 0–3”.

•If you are going use any LU pools, define them as described in “Defining LU Pools”.

To configure TN server, perform the following tasks:

•Configure a TN server access record for each TN3270 client who will use the server, or a default record that enables any client to access the server (see “Configuring TN Server Access Records”).

•If you are supporting TN3270E or TN3287 clients, you can define an association record for display and printer LUs (see “Configuring TN Server Association Records”). This record enables a TN3270E or TN3287 client to select a specific printer (by selecting the associated display LU). The client must be authorized to select an LU in the TN server access record.

Advanced options for TN server enable you to force printer responses and specify a keep-alive method for all TN3270 sessions.
