Hi guys,
I was just trying to understand the SAP memory management and I think I don't really have good understanding of the SAP memory pools that we can view via ST02 .
Under the Storage shared between work process section we have :
So what are these memory area ? "Not in pool" seems to have almost 90% of configured SAP pool memory.
Not in Pool seems to be allocated (3.4G here) the moment the SAP instance is started.
Can you please explain the concept of the memory Pools in the SAP? I have vague idea but I do not really understand this.
I think when we increase the various SAP buffers (like program,scree,Export/import), we increase these pools...
Can you please help me link these pools with the four main memory areas of the SAP:
1. Roll
2.Extended
3.Page
4.Heap
or are they entirely different?
As you can see I badly need to tune my SAP buffer memory ! Before increasing these buffers I need to understand if we have sufficient memory left in the box.
regards,
Rakesh
