Defining terminals for growth

When designing your ETO implementation, be sure to plan for growth in your network.

Recommendations:

To increase future growth potential and system availability, minimize the use of descriptors. The Logon, Signon, and Destination Creation exit routines should provide enough customization, thereby eliminating the need for unique descriptors beyond those that are required for specific terminal types.
To ensure user data is correctly handled, design exit routines carefully. In particular, carefully plan for user data that is specified during the logon process. Exit routines should work correctly, regardless of whether user data is specified.
Some terminal types, such as Finance and SLU P terminals, require user data that specifies signon information. If this data is missing, the equivalent information must be provided in the Logon exit routine (DFSLGNX0).
