HP Devices Using SNA Applications

To allow NonStop S-series servers and attached devices to use SNA applications, HP

provides software that emulates IBM batch devices (batch mode) or display terminals

(interactive mode).

Batch Mode

Remote job entry (RJE) is the process of submitting data processing jobs to a host

computer from a remote system or device and then receiving the processed output

back from the host. Exchange/SNA permits a NonStop S-series server to emulate an

SNA 3770 RJE workstation, allowing transmission of multiple data streams to and from

an SNA host running JES2 or JES3. Exchange/SNA requires either SNAX/XF or

SNAX/APN.

Interactive Mode

EM3270 is an HP product that enables HP printers, workstations, and terminals to

emulate IBM 3270 printers and terminals in order to communicate with applications on

an IBM host. Users can switch between HP and IBM applications without exiting from

either one, by pressing a special function key. Up to six different IBM host applications

can be used from a single HP terminal or workstation. An EM3270 template and set of

key caps provide easy correlation between 653x and 3270 keys.

Cooperative Processing With SNA Systems

SNAX/XF lets you develop distributed program-to-program cooperative processing

applications for NonStop S-series servers and intelligent SNA devices (such as 4700,

3600, and S/36 devices). The SNAX applications use file-system procedure calls and

can communicate with IBM environments including IMS and CICS. The HP NonStop

SQL/MP NonStop S-series server brings added value to such applications through

products like the HP NonStop SQL/MP relational database management system.

Several SNAX interfaces and companion products are especially well suited to

cooperative processing: SNAX/APC, SNAX/HLS, and the SNALU interface.
