Increasing the maxuprc

Hello,

I have not able to increase the maxuprc kernel parameter from 3686 to 3687, as recommended by Oracle 10g upgrade. I have followed the below formula.

MAXUPRC = ((NPROC*9)/10) = 3686 where NPROC is 4096.
But oracle requires 3687 as maxuprc.

Please advise.
Thanks for your help.

Re: Increasing the maxuprc

If you go through SAM, just delete the formula and enter the value you want in the field.

Then regenerate the kernel and reboot.

Re: Increasing the maxuprc

Hi Rao:

You need to increase the value of 'nproc' which is the absolute maximum number of processes system wide.

'maxuproc' must be less than 'nproc'. Hence the reason for your inability to change it.

Re: Increasing the maxuprc

Hi Rao,

Good day to you !
You need to put NPROC with 4097 to make the maxuprc become 3687. Just use SAM to change this kernel value and you need to reboot the system to get your system affected with the new kernel value.

Or you just remove the formula and change it with the 3687.

If you have a problem while you increase the value, please post the error message and I will try my best to help you solve the problem.

Re: Increasing the maxuprc

Hi,

I suggest you increase the NPROC value so that all corresponding values/parameters gets increased.

otherwise you can got SAM and remove the Formula and give the absolute value of

Hi Rao,

If you are running H-UX 11.11 then maxuprc is dynamic and can be changed.
