abap heap memory help

[dajana_rebac]

Hi,

i am getting error TSV_TNEW_PAGE_ALLOV_FAILED

and I intend to increase the following parameters:

abap/heap_area_dia from 2000000000 to 34359214080

abap/heap_area_nondia from 0 to also 34359214080

abap/heap_area_total from 2097152000 to 68718428160 (heap area dia + heap area nondia)

My PHYS_MEMSIZE is 65535 (64GB Server RAM)

Kernel version is 753

I changed the EM/TOTAL_SIZE_MB parameter earlier to 70% off PHYS MEM which is 44500

Is it ok to set these abap heap parameters this high?

Thanks.
