Kernel Parameter nfile and maxuers

KPS — Tue, 07 Jan 2003 13:51:07 GMT

Watching HP-UX Glance on our N-4000 HP-UX 11.11
server. Server's function is an Oracle DB Server running 8.1.7.... We're noticing that the File Table Kernel Parameter (NFILE) is getting dangerously close to the threshold.
We want to bump this parameter up, and have noticed that it has a few dependencies and also has a formula, which involves (MAXUSERS) and (NPTY).

NFILE = 17865 at the present time...

At the peak usage part of the day, we are ever so closely nearing this value. Wondering what a good number for this would be under these circumstances or if we should just double it?

Tks,

you yourself answered your question. You see the values closing to Threshold, then increase it by half.

Ken,

All you'll be using is a little more memory for the kernel's tables. Unless you're experiencing severe memory constraints, double it, either by doubling MAXUSERS or just doubling NFILE.

Okay great.. Just kind of taking a small poll to see if this is the best approach, or if someone that has more experience with an issue like this could recommend something else.

Thanks...
