SNA Devices Using HP Applications
The SNAX/XF, SNAX/APN with the extended logon facility (XLF), and the
SNAX/APN-EN with either XLF or the enhanced logon facility (ELF) products allow you
to use existing SNA devices—such as 3270-type terminals, ATMs, intelligent
controllers, and manufacturing-floor terminals—with applications running on NonStop
S-series servers. The same devices you use with applications on NonStop S-series
servers can also use applications in the SNA environment.
SNAX/XF software enables a NonStop S-series server to both serve and control
attached SNA type 2.0 and type 1 nodes. For example, the attached node might be an
SNA cluster controller, branching to multiple 3270 display stations and printers.
Another example of an attached node might be an IBM personal computer (PC) in
3270 emulation mode. The SNA devices can log onto, or be acquired by, applications
running anywhere in the Expand network.
SNAX/XF, SNAX/APN, and SNAX/APN-EN provide solutions for serving SNA devices
that are controlled by a separate SNA host. The NonStop S-series server and SNA
devices can be in the same SNA network, directly connected SNA networks, or
remotely connected SNA networks. This provides, for example, an easy method of
giving an existing network of SNA devices access to HP applications. The SNA
devices can log onto, or be acquired by, applications running anywhere in the Expand
network.
If you require HP applications to be started dynamically when devices log on, you need
SNAX Creator-2 software (for SNAX/XF or SNAX/APN). This software starts the
requested HP application, typically a TACL process or Pathway application that uses
one of the SNAX/XF or SNAX/APN APIs.
Figure 7-2 shows an HP application used by SNA devices using SNAX/XF and
SNAX/APN.
