How to calculate the total amount of RAM allocated to SAP and Oracle.

491 Views

Hi All,

I have a performance issue in my system. I want to change the parameter value both in SAP and DB.

I am totally confused to calculate the exact RAM allocated to SAP and DB.

Please explain how to calculate the total amount of RAM allocated to SAP and Oracle.

I have around 45GB of physical RAM is configured in the system

From oracle end

sga_max_size 11 GB

sga_target 0

pga_aggregate_target 6G

shared_pool_size 2G

db_cache_size 8G

--------------------------------

From SAP end

abap/heap_area_dia 2000000000

abap/heap_area_nondia 3000000000

abap/heap_area_total 5000000000

EM/TOTAL_SIZE_MB 17920

ztta/roll_extension 3100000000

abap/heaplimit 40894464

em/initial_size_MB 4096

Oracle end

---------------

Total Amount of RAM ( SGA + PGA)

SAP end

-----------

Total amount of RAM (abap/heap_area_total + EM/TOTAL_SIZE_MB + SAP Buffer Memeory)

Please confirm whether the above calcualtion is correct.
