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.
