Purpose of the NOF API
The SNAplus2 NOF API provides access to a standard set of commands,
called NOF verbs, that can be used to administer the SNAplus2 system
from within an application program. These verbs enable you to define
and delete resources, specify SNAplus2 parameters such as diagnostics
levels and file names, start and stop defined resources, query the
definition or current status of resources, and manage which servers on
the SNAplus2 LAN can act as backup masters if the master
configuration file server is not available.
The NOF verbs provide the same functions as commands issued to the
command-line administration program snapadmin, or as records in a
SNAplus2 configuration file. For example, the NOF verb
DEFINE_LOCAL_LU is equivalent both to a define_local_lu
command issued to the snapadmin program, and to a define_local_lu
record in a configuration file; all three of them perform the same
function, which is to specify the parameters of a SNAplus2 local APPC
LU.
You can use the Motif administration program xsnapadmin to perform
the same function as a NOF verb or an administration command (for
example, you can use the program to define a local APPC LU). However,
this program does not provide access to the full range of parameters
included in some NOF verbs. For more information about using the Motif
administration program, refer to the HP-UX SNAplus2 Administration
Guide.
You can issue NOF verbs to any of the following targets:
• A running SNAplus2 node (to manage its resources or to monitor its
operation)
• A server where the node is not running (to query the stored
configuration or to modify it for use when the node is next started)
• The SNAplus2 domain as a whole-to define, modify, or query the
configuration of domain resources (resources used to support
particular user programs, such as 3270 diagnostics parameters and
CPI-C side information entries, which are not associated with a
particular node).
The NOF API enables you to do the following:
