Currently you do not have a TN3270 server configured. Use the TN3270 Wizard to initially setup your TN3270 server. After you have completed the TN3270 Wizard, use the Advanced Setup... button to edit your configuration settings and expand them to use more advanced settings as necessary.
Before you begin, you should know a few basics.
A Telnet server is bridging between an IP network and SNA applications. A TN3270 client connects from a workstation to the z/OS mainframe over an IP network using TCP/IP protocols. The TN3270 server running on the z/OS system receives client connect requests by listening on a TCP port. Once a connect request is received, the server bridges from the TCP/IP network to VTAM and establishes an SNA session with the SNA application. The server then manages an end-to-end connection from the TN3270 client through the IP network to the server and from the server to the SNA application.
The TN3270 server needs to be configured with some basic information. The server needs two pieces of information to be configured properly:
The name of the SNA LU used to represent the client to the SNA application, when
a client connects.
Since TN3270 is bridging between your previous SNA network, it is likely that your SNA applications
expect the end users to be represented using specific SNA LU names. Therefore, TN3270 server allows you to
configure the LU names to server. There are no defaults.
The name of the SNA application to which the client will connect.
It is likely that in your SNA network, the SNA LU definition statements were defined to either send
the SNA LU terminal a specific USSMSG10 or to automatically log the terminal on to a specific application when
the terminal LU was activated. Since the SNA LU definitions are no longer used, the equivalent information
must be defined to the TN3270 server.
