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. 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. Readers. This is transmission
and translation information about each logical reader. For JES2
and JES3, you must configure from one through seven readers. For
VSE/POWER, one reader is assumed. The number of logical readers
must match the number of readers configured on the host. Writers. This is translation
and formatting information about each logical writer. The logical
writers receive output data streams from the host. You must configure
an NRJE writer for each printer or punch defined at the host.
 |  |  |  |  | CAUTION: You should not modify the configuration for NRJE
while it is running; if you do, the results are unpredictable. You
can modify the configuration of another, non-running SNA subsystem
while SNA NRJE is running.NRJE uses the files INPUT and OUTPUT for processing
internal messages. Therefore, these files are reserved for use by
NRJE and should not be specified by the user. Use of these files
could result in corrupted user data. |  |  |  |  |
