HP-UX SNAplus2 NOF Programmer's Guide
Introduction to the NOF API
Purpose of the NOF API
Chapter 152
• Develop your own application programs to manage the SNAplus2
system
• Develop application programs that use the other SNAplus2 APIs so
that they can also manage their own resources (for example, an
APPC application can check that the communications link to its
partner TP is active before attempting to allocate a conversation or
can define the remote LU where its partner TP is located).
Node Configuration File
Configuration information for each SNAplus2 node is held in a text file
on the computer where the node runs. This file includes information
about the node's resources, and specifies which resources will be active
when SNAplus2 is started. When you start the node, the file provides an
initial definition of the resources that are available; you can then use the
NOF API or the SNAplus2 administration tools to modify the running
node's resources as your requirements change.
You can set up multiple configuration files, to store different SNAplus2
configurations for use at different times, and select which of these files to
use when starting the SNAplus2 software.
Configuration in an APPN network is a dynamic process; you can add,
delete, or modify resources as necessary while the SNAplus2 software is
running. The configuration file provides an initial definition of the
available resources and stores the current definition so that you can use
it again when you need to restart the node, but it is not necessary to
define the entire configuration before starting the SNAplus2 software.
Domain Configuration File
Configuration information for SNAplus2 domain resources is held in a
single text file on the master server. You can set up multiple domain
configuration files, to store different SNAplus2 configurations for use at
different times, and select which of these files to use when starting the
SNAplus2 software on the master server.
