High Availability Monitors Version A.03.02 Release Notes

NOF Indications
SNA_NET_INDICATION
Chapter 6 1157
SNA_NET_INDICATION
This indication is generated when another NOF application or a
SNAplus2 administration tool makes a change to the SNA network file
sna.net. The target for this verb, identified by the target_handle
parameter on the REGISTER_INDICATION_SINK verb that registers
to receive this indication, must be the sna.net file.
VCB Structure
No specific VCB structure is associated with this indication. To register
for SNA network indications, the application specifies the value
AP_SNA_NET_INDICATION as the indication_opcode parameter on
REGISTER_INDICATION_SINK. When a change is made to the SNA
network file, SNAplus2 then reports this to the application's callback
routine by sending a copy of the VCB from the NOF verb
(ADD_BACKUP or DELETE_BACKUP) that made the change.
To enable the application to distinguish between SNA network
indications and asynchronous responses to its own NOF verbs issued to
the SNA network file, SNAplus2 changes the primary_rc parameter in
the VCB for an indication. The value AP_INDICATION identifies a VCB
associated with an SNA network file indication; the value AP_OK, or any
other value, indicates an asynchronous response to one of the
application's own NOF verbs.
