SNAX/XF LU Network Services Manual

3 Application Example
097841 Tandem Computers Incorporated 3–1
Section 2 presented concepts for planning a LUNS configuration; these concepts are
applied to an example application presented in this section. The example has two
parts. The first part illustrates the implementation of a configuration that allows
terminal users on a Tandem system to log on to applications both on their own system
and on the host and to establish a static passthrough session with the host. The second
part illustrates the addition of a remote Tandem system, connected to the first by an
Expand link. On this second system resides another application, which terminals on
both systems can access through LUNS.
All SNAXUTL and SCF commands needed to implement this example are shown.
Creating the Basic
Configuration
Figure 3-1 illustrates the first part of the example. The figure shows an SNA host
linked to a Tandem system (\SYS1). Residing on the host is the application TSO.
Residing on \SYS1 are the TACL application, a Pathway application called Order
Entry, a PATHMON process called $PATHX, and the Tandem Creator process. SCF is
used to configure two gateway LUs (LU1 and LU2). These LUs enable LUNS to
establish both static and nonstatic passthrough sessions for the two 3278 terminals
(LU3 and LU4) attached to \SYS1.
