z/OS® Communications Server can dynamically adjust how frequently an OSA-Express2 or later feature interrupts the host for inbound traffic. By monitoring traffic patterns, the stack can adjust the interrupt-timing values to maximize throughput.
To configure an OSA-Express2 or later feature for dynamic LAN idle timer, use the INTERFACE or LINK statement with the dynamic inbound performance setting (INBPERF DYNAMIC). For information about dynamic LAN idle timer and the INBPERF parameter, see DEVICE and LINK – MPCIPA OSA-Express QDIO devices, INTERFACE - IPAQENET OSA-Express QDIO interfaces, and INTERFACE - IPAQENET6 OSA-Express QDIO interfaces in z/OS Communications Server: IP Configuration Reference.
