SNA NRJE Node Manager's Guide

Chapter 1  SNA NRJE Overview 

Systems Network Architecture Network Remote Job Entry (SNA NRJE) is a
data communications package that provides HP-to-IBM batch communications
in a Systems Network Architecture (SNA) environment.  With SNA NRJE, you
can submit batch jobs for processing on an IBM host.  A spool file is
created to receive the input job files.  Once communication with the host
starts and the host begins to accept job input, each job is routed to its
destination based on its position in the queue.

SNA NRJE workstations send jobs to the host over logical readers and
receive output from the host over logical writers.  A logical reader is
configured for each workstation so that data can be transferred from the
HP 3000 to the host.  Workstations receive output from the host through
logical writers.


NOTE  In this manual, the term SNA link product is used when the
      information being given is true for all of the SNA link products:
      SNA Link/V, SNA/SDLC Link/XL, and SNA/X.25 Link/XL. The terms SNA 
      Link/V, SNA/SDLC Link/XL, and SNA/X.25 Link/XL are used when a
      distinction among the three products is necessary.


SNA NRJE uses the SNA link product, a bundled hardware and software
product that supports a logical and physical connection in an SNA NRJE
network.  SNA NRJE and the SNA link product form an HP 3000 subsystem
that allows the HP 3000 to emulate the functions of an IBM 8100 DPPX/RJE
workstation.  Architecturally, this is an SNA Physical Unit Type 2
(PU.T2), Logical Unit Type 1 (LU.T1) node.  Figure 1-1 shows the
different LU types that SNA NRJE can implement.
