Specifies how VTAM® paces the flow of data from the boundary node containing the PLU to the boundary node that performs pacing for a channel-attached SNA device.
number_of_requests specifies
the maximum number of normal-flow requests that the PLU sends for
a given LU-LU session before waiting for a pacing response. No further
normal-flow requests can be sent to the logical unit until it is ready
to receive them.
Note: You can use the FIXED option on this operand.
FIXED is an NCP option that allows you to override adaptive session
pacing and use fixed pacing instead.
To use the FIXED option, you must code (N,,FIXED). The second comma represents M or a minimum value that is used by some pre-ENA nodes.
For more information on pacing, see z/OS Communications Server: SNA Network Implementation Guide.
