I am unable to guess what you tried, or what
happened when you tried it.

How about these?
What you wish to do.
What you did.
What happened when you did it.
"I can't do something" is not a useful
problem report.
Doesn't "sam" provide a tool for changing
kernel parameters? Some parameters are
dynamic (changes take effect immediately),
and some are not (changes take effect after
reboot). Trying to guess what you don't know
is not my idea of a good time.

How about these?
What you wish to do.?
>> I wish to do change static kernal parameter (nfile valuse from 1200 to 1300).
What you did.?
>> Use SAM ->Kernal Configuration ->select->nfile-->modify->
>>Server sucesfully backuped up my old.kernal and rebuilded new keranl -> after reboot
What happened when you did it.
>>COnsole message "SOFTWARE Failure "
>>Hence Its production Servers<< I am beyond my downtime schedule<
>>I reboot in Single User mode< Booted the Server using ISL> hpux boot /stand/vumix.prev
Than the Server booted as per normal "
#cp vmunix vumix.prev
#shutdown -ry 0
>>"I can't do something" is not a useful
problem report.<<
Hope This Helps
Thanks,
Johnson

Re: Unable to Change Kernal Parameter for HPUX 11.11
So what happened when you did? Note this is still very small.
>Console message "SOFTWARE Failure"
This isn't helpful. This happened when you ran your application or when you rebooted?
If the former, was nfile changed to 1300?

>>Server unable to boot, Console message showed up Software Failure.<<
>Console message "SOFTWARE Failure"

This Happened Once Server reboot after the kernal parameter change.<<<
If the former, was nfile changed to 1300?
No, That was the Customer ,issue they are not able to change any kernal paremeters in this Box.
so I requested downtime from the Customer and adviced we shall try changing any static kernal parameter.
So please advice why does it doesn't allow me to change any kernal parameter values?
Thanks,
Johnson

Re: Unable to Change Kernal Parameter for HPUX 11.11
The minimum value allowed is 2048. The maximum value allowed is the maximum 32-bit signed integer value that can be represented in the system. The value is further constrained in that it must be equal to or greater than two times the per-process open file hard limit: (nfile >= 2*maxfiles_lim).
please check the /etc/conf/master.d/core-hpux for range specified for nfile.can you try with kmtune instead of sam and post the output

This is useless, it doesn't tell who or what.
Can you provide 10+ lines of context?
Try changing nfile to at least 16384.
