I have 128 G RAM,
according to oracle my swap size should be 16G, but linux say memory above 64G swap size should be 4G.
but oracle in their documentation say
Contact your operating system vendor for swap space allocation guidance for your server. The vendor guidelines supersede the swap space requirements listed in this guide.
I am planning to install Oracle 11R2 on CentOS, i have two different number for swap size from the documentationsIf you care about documentation than I suggest start to use certified platform. You are already working on not certified platform so I belive SWAP size is not so important or biggest problem.
which one i should follow? Oracle or Linux
