Hi! I have deployed SAP IDES ECC 6.0 for Oracle on VMWare Workstation with Windows 2003. There are 16 GB of RAM in the host. Out of them I assign 14 Gb for the virtual machine .
The system is working, but response time is not satisfactory.
Task Manager shows the virtual machine uses only 14679260-12535540 = 2143720 byte of physical memory and the rest 12 GB remain Available. Meanwhile 18 Gb is committed. Performance counters display high load of disk system.
How can I make SAP+Oracle utilize physical memory to the maximum?
This being Windows the only thing I would be initially interested in is PHYS_MEMSIZE. Can't see it in doc you have attached. Please let us know its value from RZ11.
I found that PHYS_MEMSIZE was 512 MB in Instance Profile. I changed it to 14335 and restarted Application Server. However nothing changed. Still the virtual machine utilizes only 2GB of physical memory out of 14GB. Moreover I have another virtual machine with Windows 2003 x64 where SAP IDES ECC6 + Oracle are also deployed. The situation is similar there.
First of all PHYS_MEMSIZE should be memory to be used by SAP instance only and not SAP+Oracle. You need to split it between SAP and Oracle in may be 50:50 or 60:40 ratio.
. Next there would be operations that would be disk intensive because of which Disk I/O is huge and then there would be CPU intensive processes. No matter what memory CPU intensive operations will keep on hammering CPU.
Also response time is not just memory dependent. Very wrong idea. Check if your buffers are big enough also.
