SCSFLOWCUSH is a system parameter that specifies the lower limit for receive buffers at which point system communication services (SCS) starts to notify the remote SCS of new receive buffers. For each connection, SCS tracks the number of receive buffers available. SCS communicates this number to the SCS at the remote end of the connection. However, SCS does not need to do this for each new receive buffer added. Instead, SCS notifies the remote SCS of new receive buffers if the number of receive buffers falls as low as the SCSFLOWCUSH value. The default value is adequate on most systems. If a systems communication architecture (SCA) port is not configured on your system, this parameter is ignored. SCSFLOWCUSH is a DYNAMIC parameter.
