Pagefile question

Hello Experts,

I'm have to set up the pagefile for a SAP Netweaver new installation:

OS: WinServer 2008

BD: Oracle 11G

SAP: NW AS ABAP/JAVA 7.01 (central installation)

I want to know what are the considerations, for example, lets assume the following:

- I need a page file size 20 GB.

- I have the following units:

C:\ - Operating system

D:\ - SAP Kernel

E:\ - Oracle

F:\ - Oracle

G:\ - Oracle

Should I distributed the pagefile in all the units?

Should I assigned all the pagefile where the OS is installed?

Should I created a new unit (for example H:\) and assigned all the page file?

I have only found SAP Notes regarding how to calculate the pagefile but nothing about It's distribution.

Thanks for your time,

Regards,

JAM
