Summary :
This SAP Note discusses configuring the Internet Communication Manager (ICM) for optimal performance, detailing default and maximum values for parameters like icm/max_conn, icm/max_sockets, and icm/req_queue_len across different SAP versions and platforms. It explains how active HTTP connections are managed, influenced by user behavior and system settings such as Keepalive timeouts. Recommendations include adjusting operating system parameters to allow higher loads and regular checks of system capabilities against parameter settings, especially concerning the maximum number of open file handles (sockets). Adjustments should be made judiciously, based on each specific processing environment and SAP's guidance.
