NMMGR Configuration Overview

Use NMMGR to create or modify an APPC subsystem configuration. The NMMGR utility is described in Using the Node Management Services Utilities; if you are not familiar with NMMGR, you should read that manual before continuing.

You configure the APPC subsystem by defining the network in which it will operate, the nodes and LUs that will communicate over APPC sessions and the properties of the APPC sessions. Table 4-3 “NMMGR Screen Index” lists the NMMGR screens used to configure the APPC subsystem, and it gives the page number in this chapter where each screen is described.

Configuration File Validation

NMMGR has a utility for validating the configuration file to ensure that the APPC subsystem configuration data is logically and syntactically correct. It also checks the APPC subsystem configuration against the SNA node (SNA/SDLC Link/XL) configuration for correctness and consistency. For example, it checks to make sure an LU name you configure for the APPC subsystem is associated with the same SNA node in both the APPC subsystem configuration and the SNA node configuration.

You should validate the configuration file after completing any of these tasks:

An initial configuration of one or more SNA nodes.
An initial configuration of one or more SNA Services.
A modification of an existing configuration.

The NMMGR validation utility validates the entire HP-IBM portion of the configuration file; see Using the Node Management Services Utilities for details. Appendix A “Messages” contains a list of the NMMGR validation messages that pertain to APPC subsystem configuration.

Creating a Critical Summary

NMMGR allows you to create a summary of critical APPC subsystem configuration data. The critical summary is a printout of the APPC subsystem data in the configuration file. It can be used to check current contents of the configuration file to determine whether the configuration is correct. The critical summary is generated through NMMGR; see Using the Node Management Services Utilities.

Appendix B “Sample Configuration” gives an example of critical summary output.
