PHYS_MEMSIZE Parameter ...

[former_member309601]

Hi, I have an SAP ERP 6.0 server with: 8 GB RAM, Oracle, Win 2003 64 bits, my problem is some process need more memory and my server has too much swapping. When I check PHYS_MEMSIZE parameter its 1024, when I believe it must be total RAM size (8000). My swapping is 16GB.

I have read 88416, 1518419 notes, but they do not explain how can I change PHYS_MEMSIZE or which setting can I use with it. These notes explain that PHYS_MEMSIZE may be not defined and it will take total memory server. I have checked in another servers SAP with SQL Server, and fine, PHYS_MEMSIZE has total RAM, but with my server with Oracle when I try to change this parameter, my server does not star-up ..... If I deleted , my server does not start-up.

I need change PHYS_MEMSIZE to total RAM memory size.

Regards.

This parameter specifies the amount of main memory to be used by SAP instance . If you have DB and APP running on the same system , then allocate 60% of the value to APP. So set the parameter to 5120 . Once you set this , no manual maintenance of other parameter is required. The SWAP seems to be ok , but make it 20GB if you have space on your disk.
