Windows swap, despite having enough RAM and Buffer

[Former Member]

Hi,

My SAP landscape is:

Application Server:

1. Windows 2003

2. 32GB RAM

3. 90GB Page File

SAP ECC6.0 installed.

PHYS_MEM = 28GB.

In ST02, there is no swap. Very stable. Occasional use of Private Memory.

However, on OS level, the swap is amazing. Physical free always around 20GB RAM, but the disks are swapping in/out by disp-exe processes.

How can I minimise this and let SAP use the physical RAM?

Hi,

This a very well known problem.

You have to install the Microsoft specific hotfix which was designed for SAP servers.

Check OSS [Note 1009297 - Windows Server 2003 Family: High Paging Rates|http://service.sap.com/sap/support/notes/1009297]

Thanks

I'd been searching at the wrong place.

Will install the patch over this weekend.

Cheers,
