Hi All,

This is a compulsive tuning disorder question. I'm
just curious if anyone has experimented/benchmarked
the use of the swappiness parameter on Linux 2.6
kernel with Oracle running?

On a dedicated database server it would seem
preferrable to set this lower than the default (60) as
the Linux cache won't be adding much value to the
Oracle cache. Has anyone done this - what's sensible?
10, 5 - even 0? Did it make any noticeable difference
in an end-user measureable sort of way?

(Yes, I know that fixating on a randomly chosen
parameter is an upside-down method of tuning
performance; I'm more interested in the technical
details of this particular "adjustment" than using it
to tackle anything specific at the moment!)

Thanks!
Charlotte
