Overview of Parameters for Windows
All relevant memory management parameters are set with an optimal default value so that all manual configurations are unnecessary.
The following table gives you an overview of these values.

where
[MM] = size of the physical main memory
[PM] = value of the profile parameter PHYS_MEMSIZE (default value=[MM])
[BE] = maximum possible number of users (calculated from [PM])
The zero administration memory management on Windows tries to reduce the number of relevant profile parameters so that maintenance and configuration of the application server is simplified, and the available resources are optimally used.
