Understanding and Mapping Access Routine Parameters

When an access routine connects to an SNA gateway, it communicates with the gateway by using an access name and one or more parameters (such as application name, logon mode, session address, PU name, and LU name).

Your existing DECnet SNA Gateway manages access to LUs using a combination of PU name and session address. These may be grouped together to facilitate network access by using Access Names. However, the syntax of a DECnet SNA Gateway LU name (an old-style LU name or old-style name) is not recognized by the SNA Server. In order to continue using these old-style LU names with the Access Server Gateway, you must map them to a format that SNA Server recognizes.

On DECnet SNA Gateways, you define access names and parameters in the gateway configuration file using one or more SET ACCESS NAME commands and parameters. On an Access Server Gateway on a Windows NT system, access names and parameters are specified using the Access Server Manager.

This section discusses how old-style LU names in a DECnet SNA Gateway are created and used. It then describes various options for setting up LU names in SNA Server and configuring them in the Access Server Manager so that you can continue to use the old-style LU names in your Access Server Gateway.
