NMMGR Configuration Overview After you have completed the SYSDUMP configuration (for NRJE/V) or the SYSGEN configuration (for NRJE/XL) 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. For NRJE/XL, you use the SYSGEN utility to configure an ldev for the virtual reader. 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.
NOTE For each workstation, you must also build a job stream to start the NRJE workstation monitor. See chapter 4 for more information.
