icm/max_sockets 

Use

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 two sockets for each connection.

·        If the ICM in SAP Web AS is communicating with an SAP J2EE Engine as well as with the ABAP Engine, it requires two sockets per connection.                

Prerequisites

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.                  

Procedure

The default value is 2048.

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).
