Introducing SNA NRJE
Introduction
Multiple data sets can be created for each job submitted to a host. An
output data set is always created for each job submitted to a host for
Job Control Language (JCL) logging. Data sets are received at an
HP 3000 using an SNA link product. Data is decompressed and
translated if desired. Data sets are returned to a logical output device, a
logical writer, with those from a specific job typically making up one
spool file. A logical writer must exist for each printer or punch defined
at the host for your remote.
NRJE uses the console command and message stream between a
workstation and the host job entry subsystem. An NRJE user sends
commands and receives messages through the console.
All job entry subsystem commands configured for a workstation are
permitted. (This, however, depends on the capabilities assigned the
user by the node manager.)
NRJE can be accessed two ways: interactively and programmatically.
Interactive access is through the NRJE subsystem command
interpreter. Programmatic access is through a user-written program
calling NRJE intrinsics. Most NRJE commands correspond with
intrinsics.
Operating Environment
These are the operating environments needed for SNA NRJE:
• HP 3000 to SNA host: SNA NRJE emulates 8100/DPPX/RJE. An
SNA host must be configured for an IBM 8100 DPPX/RJE
workstation when communicating with an HP 3000 running SNA
NRJE. See the SNA Link Services Reference Manual or the SNA
NRJE Node Manager’s Guide for information on configuring SNA
NRJE on your HP 3000 system.
• SNA Host: An 8100/DPPX can communicate with IBM System/370,
43xx, or 30xx, or plug compatible processors using a 37x5 type
communications controller.
