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.
With the ICM the number of sockets per connection depends on the installation type of SAP NetWeaver Release as of:
1 Socket

Value Range and Syntax
You can set values between 2048 and 32768
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 .
However, if you want to make more than 1024 connections possible with the Web Dispatcher, or more than 2048 connections with the ICM, you can increase this parameter (following the guidelines of the operating system).
