Hi,

There are 2 ways,

1. Use SAM -> Kernel Configuration -> Tunable Parameters
2. Use command line: # kmtune , man kmtune for more info

Hi,
Have a look at this HP link;
http://docs.hp.com/en/5187-0701/ch03s03.html

This should help you to tune as you want it....

Hi chetana07
this is very useful method to modify kernel parameter at once.

[/]# cd /usr/sam/lib/kc/tuned
[/usr/sam/lib/kc/tuned]# vi newkernel.tun
# New Kernel Parameters
msgmax 32768
msgseg 32767
nproc 4200
.
.
.
save file and type sam
[/]# sam
sam-> Kernel Configuration -> Configurable Parameters
-> Action -> Apply Tuned Parameter Set -> Select '#New Kernel..'and OK
->File-> exit -> Select 'Create a New Kernel' OK
-> Select 'Move Kernel Into Place and Shutdown/Reboot System Now' and OK
System will reboot and kernel parameter modification completed.
have a nice day!!
