This parameter determines the maximum number of sockets open (at the same time) in the ICM or in the SAP Web dispatcher.

Depending on the connection type one or two sockets are needed for each connection.

  • The SAP Web Dispatcher always requires 2 sockets for each connection.

  • The ICM in the SAP NetWeaver Application Server requires 2 sockets for each connection if it communicates with an AS Java as well as the AS ABAP.

Integration

Usually the administrator can configure on the operating system the maximum number of sockets a process can have open in parallel. There is no reason to increase the value of this parameter. Refer to the operating system documentation.

You can restrict the number of possible connections in the parameter icm/max_conn.

If, however, you want to make more than 1024 connections possible, you can increase this parameter (following the guidelines of the operating system).
