Kernel Tuning

[P Arumugavel]

Hi dear Gurus...
Please help me to have clear idea on below:

What are the differences between HP-UX 10.x and 11.x in kernel tunable parameters, kernel tuning commands and updating new kernel and how to perform the same?

Your guidance are mostly appreciated...

11.11 and before have kmtune(1m).
11.23 and later have kctune(1)and lots of parms are dynamic, even more so on 11.31.

[Emil Velez]

most of the parameters are the same except

HPUX 11.X supports multiple threads per process and there are tunables for that.

Different command for kernel tuning at 11.11 and it changes at 11.23 and 11.31

with 11.23 there are many tunables that are dynamic.

with 11.31 most kernel tunables are dynamic.. YOu can see a trend there.
