You mean you want to change the value of these parameters...
In your case I would recommend the use of SAM since you may fall on dependencies between values...
Just type sam and go to kernel configuration

Funny I can see them all except one:
semmap
But if you had read the release notes especially : (release notes 11iv2 oct 2003)
http://docs.hp.com/en/5992-1968/5992-1968.pdf
On page 82 you would have noticed:
Quote:
• System-V IPC Kernel Tunable Parameter (semmap)(Obsolete): The memory allocation of
semaphore sets previously controlled by semmap is now done dynamically by the kernel.
The semmap kernel parameter is no longer tunable.
So before continuing further I would recommend you to look at the man pages of
kctune(1M) kmtune(1M) kclog(1M) kconfig(1M)
And read carefully:
Chapter*10*Configuring the Kernel

Hi,

Thank you for your help, after setting the kernel parameters values using the kmtune -u -s param=val now i could able to see those parameter names in the kernel configuration list.
