10.20 tunable parameters

Benjamin Folk Jr._2 — Thu, 13 Oct 2005 10:22:40 GMT

Are there any HP-UX 10.20 kernel parameters equivalent to the following that are found on more recent versions of HP-UX?
physmem
lotsfree
minfree

Thanks,

Ben

According to http://docs.hp.com/en/1219/tuningwp.html#lotsdes
lotsfree and minfree weren't tunable until 11.0. I've never heard of a tunable "physmem" on any release (it isn't tunable on 11.X either... unless you consider using -M as a boot argument as "tuning"). There's an "aio_physmem_pct" but that's not likely to be what you meant.

Do your developers know HP-UX 10.20 is unsupported and has been for years? Much more would need to be done to make it a secure and viable OS today than just tuning the kernel. The lack of kernel threads makes it a poor choice for many applications being developed today.
