Extended memory is virtual memory space or Real Memory ?

[Former Member]

HI ,

I would like to know whether the extended memory is virtual memory or its real memory. What is the parameter used to set the usage of the real memory of the system and the virtual memory of the system ( I want to know with ref to UNIX environment), and also clear about the hep memory( virtual or real).

Thanks in Advance

Hi, I hope this will help:

The virtual memory consist of physical memory and OS swap space. Virtual memory can be allocated by the SAP system.

In the virtual memory exist shared memory and local memory.

Your question was regarding extended memory. Extended memory (user context) exist in shared memory. Heap memory exist in local memory.
