NOF Restrictions Based on Node
Configuration
The DEFINE_NODE verb includes parameters that define the range of
functions supported by a node. Several NOF verbs relate to optional
functions that a node can or can not support; these verbs are valid only
when issued to a node that supports the relevant functions.
This section summarizes the optional functions that affect which NOF
verbs can be used. For more information about these functions, see
“DEFINE_NODE”.
APPN LEN Node Restrictions
The SNAplus2 local node can be an APPN end node or a LEN node.
The following NOF verbs are only valid at a network node or end node;
the primary return code AP_FUNCTION_NOT_SUPPORTED is returned if you
attempt to issue them at a LEN node.
• DEFINE_CN
• DELETE_CN
• QUERY_CN
• QUERY_CN_PORT
Multiple Domain Support (MDS) Restrictions
The local node can be run with or without Multiple Domain Support
(MDS). The following NOF verbs are only valid at a node running with
MDS; the primary return code AP_FUNCTION_NOT_SUPPORTEDis returned
if you attempt to issue them at a node without MDS.
• QUERY_ACTIVE_TRANSACTION
• QUERY_MDS_APPLICATION
• QUERY_MDS_STATISTICS
