SNA NRJE Node Managers Guide (30292-90007)

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.
