Heap Memory In Mem [KB] in ST02

[Former Member]

Hello,

In ST02 transaction, SAP Memory section. there is a last line Heap Memory in column In Mem[kb].

Can anyone tell me what does it mean for the value in Heap memery In Mem[kb]

and which parameter used to define this value.

In my case Heap Memory In Mem[kb] is equal to Heap memory Maximum used.

Thanks,

Piyush,

SAP allocates various memory structures to the work processes once dialog step is assigned. Heap memory is the last in the sequence. Once this is assigned wp goes in private mode and restarts once it reaches abap/heaplimit.

Have a look at following link too for various parameters.

Thanks for your reply.

But I know the concepts of SAP memory management.

I just want to know, what does it mean by the value in ST02, section SAP Memory -> Row (Heap memory) Column (In Mem KB).

SAP Memory In Mem[KB

Roll area 262,144

Page area 131,072

Extended memory 7,335,936

Heap memory 3,696,771

why there is a value in heap memory for In Mem, and what does it mean, what is the parameter to set this value.

Thanks,

Exactly, all that information is in the above link I believe.

Hello Piyush,

The In Mem[Kb] is the created memory area or the total memory allocated with profile parameters.

For extended memory it shows the value of profile parameter: em/initial_size_MB converted in Kb.

Thanks,

I know for extended memory.

I need to know which parameter created in In Mem[kb] for Heap memory.

Why there is In Mem area created for Heap memory.
