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.
