Implementing Memory Management (UNIX)
As described in Functions of the SAP Memory Management System, there are various types of memory ( SAP Memory Types).
The memory management system decides when memory type is allocated, which memory type is allocated, and the allocation sequence of the different memory types.
This all depends on the platform and the work process type (dialog or non-dialog work processes). The allocation of memory for UNIX platforms is described in more detail under Allocating Memory for User Contexts.
Under AIX, you can also use a different method to implement the extended memory. This means that more extended memory is available for an individual context. The procedure and the benefits thereof are described in more detail under Configuration for AIX.
