Hi Prithviraj,
I have increased em/initial_size_MB several times and reached to 128,000, it is almost 3 times larger than initial value.
But ztta/roll_extention limits EM per user context and its maximum value is 64,000,000,000.
In my case, EM was fully used, about 64GB, and about 155GB HEAP was assigned.
abap/heap_area_total was 256,000,000,000 and for nondia was 0, that meant HEAP didn't exhausted.
That's why I doubt the relation between requested storage size and ztta/max_memreq_MB.
What do you think?
Regards,
