4.16.2 Parameters
opcode
AP_NN_TOPOLOGY_NODE_INDICATION
primary_rc
AP_OK
data_lost
Specifies whether any previous NN topology node indications have been lost. If SNAplus2 detects a condition
that prevents it from sending an indication (for example an internal resource shortage), it indicates this by
setting the data_lost parameter on the next indication after the condition has cleared. Possible values are:
AP_YES
One or more previous NN topology node indications were lost. Later fields in this VCB may be set to
zeros.
AP_NO
No previous NN topology node indications were lost.
deactivated
Specifies whether the node has been deactivated or activated. Possible values are:
AP_YES
The node has been deactivated.
AP_NO
The node has been activated.
node_name
Network qualified node name from Network Topology Database. The name is a 17-byte EBCDIC string,
padded on the right with EBCDIC spaces. It consists of a network ID of up to 8 A-string characters, an
EBCDIC dot (period) character, and a network name of up to 8 A-string characters.
node_type
Type of the node. Possible values are:
AP_NETWORK_NODE
Network node.
AP_VRN
