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.

Hi,

Ideally PHYS_MEMSIZE represents how much memory you can allocate for your sap application.

Singe you have 8 GB RAM, I would propose to change the value of PHYS_MEMSIZE = 4096.

Check swap = 24 GB RAM.

Hope this is useful.
