table full increase NFILE

[I.Delic]

Hi,
Two weeks ago I have posted a tread about changing the NFILE value en I did get some interesting answers that I can use.
There are two ways to make some changes to kernel.
Trough Sam or directly hardcoding !

This second option is for my not very clear.
If I open SAM and goes to Kernel Configuration to “ nfile” section I see one big formulae.

There is no way (that I know) to set size of my nfile parameter to let say 5000.
I have to change one number in this difficult formulae to increase this value.
It is little bitt tricky for me. I don’t witch number I have to change.

I sow some treads that’s suggest just to delete all formulae and put instead one number.
In my case I have to put number 5000.

Is this solution ?

I have to be shore because this is a production machine.

I know I have to reboot this box after I made some changes to kernel.

Some of you told me to Hardcoding this value with :
kctune nfile=XXXXX and rebuilding the kernel. ??

How I have to rebuild a kernel manually ?

I have to be very shore witch way is the easy and save !

Version of my UNIX is :
HP-UX nloos2u1 B.11.11 U 9000/800 3144009684
We have 2 GB of RAM memory
It is a RP 3440 machine

Masuser parameter is 125 at this point.

By using the SAM I can increase this parameter trout SAM (nice and easy) witch will automatically increase the value of NFILE


Thank you al in advance

Yes. You will find that experienced admins completely erase most of these formulae and replace them with a constant value --- just as you did. Many of the formulae are outdated and were a guess at best. They prevent you from making some really bad choices but also prevent an experieced admin who knows his requirements from making precision adjustments.
