Kernel Parameters...

[Demerson Zounar_1]

Hullo All,

I need to check some kernel parameters in HP/UX 11.00. The parameter are 'File Descriptors' and 'Shared Memory'. How can I see them?

Thanks in advance...

Hi:

You'll need to understand the kernel parameter names that are used. This 11.0 document will help:

http://docs.hp.com/hpux/onlinedocs/os/KCparams.OverviewAll.html

To see your server's settings, do:

# kmtune -l

The Easy way is to use SAM. From SAM go to configuration -> tunable parameters(or kernel params).

For shared memory there are several kernel parameters based on what is being allocated.
schmmax
maxdsize
maxssize
maxtsize

If you select the items listed above you can press F1 and receive help and info on each parameter.

If you already know these, you can look at /stand/system and grok what you need from there.

Regards,

The command is 'kmtune' or 'sysdef'. You probably want to look at 'nfile' - system wide number of files. There is also nofiles - process limit of open files. You can also use SAM to examine these settings under sam->Kernel Configuration

Hi,

sysdef > filename and then view the file. Go to SAM and go to tunable kernel parameters and you can read the descriptionof each parameters.
