Short text
Controls whether Heap or EM is allocated first in nondia work processes
Parameter Description
The parameter provides the possibility to change the memory allocation sequence in non dialog work processes.
In the standard memory management the default value ‘default’ for non dialog work processes is allocating memory in the Heap first.
In the memory models ‘ESSHM’ for AIX or ‘map’ for Windows and Linux, the non dialog work processes are allocating memory from extended memory first.
If there are any reasons to change the default allocation sequence the parameter abap/nondia_allocation_sequence could be used.
To allocate Heap first and EM second, the parameter should be set to:
abap/nondia_allocation_sequence = heap-em
To allocate EM first:
abap/nondia_allocation_sequence = em-heap
To check the current allocation sequence, the report RSMEMORY can be used.
