SNA NRJE Conﬁguration

NMMGR Conﬁguration Overview

After you have completed the SYSDUMP conﬁguration (for NRJE/V) to

install the virtual reader, and after the link is conﬁgured, you are ready

to conﬁgure NRJE. The conﬁguration is done by using NMMGR to

create or modify a conﬁguration ﬁle. The basic operation of NMMGR is

described in Using the Node Management Services Utilities; if you are

not familiar with NMMGR, you should read that manual before

continuing. Note that you must have node manager (NM) and network

administrator (NA) capabilities to use NMMGR.

NOTE

When conﬁguring SNA NRJE, the conﬁguration ﬁle can be named

anything you prefer. However, when you run SNA NRJE, it looks for a

conﬁguration ﬁle named NMCONFIG.PUB.SYS. For example, you could

have these conﬁguration ﬁles:

XYZ.CONFIG.SYS

CONFIG1.FILES.SYS

FILE3.CONFIG.SYS

If you wanted to use FILE3.CONFIG.SYS when you ran NRJE, you

would have to rename or copy the ﬁle to NMCONFIG.PUB.SYS before you

started NRJE.

NRJE workstations manage job transmission to the host by using

logical readers. For NRJE/V, you conﬁgure a virtual reader into the

I/O system through the SYSDUMP utility. This reader is an MPE

spooled device that holds submitted jobs until they are transmitted to

the host. When the system is rebooted, NRJE/XL will complete the

conﬁguration process for you, using the Logical Device conﬁgured on

the NRJE Conﬁguration: Reader Data screen for each workstation.

Workstations receive output data sets from the host (by using logical

writers). Each NRJE workstation is associated with an SNA node,

which manages communication with the SSCP and passes the data to

the link for transmission.

You conﬁgure these items for an NRJE workstation:

• SNA node and workstation identiﬁcation data. This is the

name of the SNA node that the workstation will use, and data that

identiﬁes the workstation to the host.

• LU data. A list of up to 16 LUs can be conﬁgured for a remote

workstation, as well as an autostart ﬁeld for each LU.

• The virtual reader (for NRJE/V). This is transmission and

translation information about the virtual reader. The virtual reader

holds submitted jobs until they are transmitted to the host. This

reader is an internal MPE spooling device and has no corresponding

deﬁnition at the host.
