Hi
How can I list my kernel params without going into sam.

Thanks in advance.

Hi Paula,

Do you mean all params?
Not only the ones listed in /stand/system ?

I'm sure others know commands (..I don't think I'll ever learn enough of them..)
sysdef is handy, but that's not going to cut it here.
So I will tell you what I have a habit of doing..
When I config/reconfig a kernel I have a habit of saving the this to a file...that way whenever I want to check it out later or print it out...I can.
It's just a habit I have...just a thought you might like,

Hi Dan

Yes I was after all the params currently in the kernel.

/stand/system just lists changes from default (I believe).

Paula,
the sysdef command will show you kernel params. there's talk of it being obsoleted though. it does not always agree with what you can see through SAM.

the /stand/system file will show you only what is tuned. if a parameter is not listed there, it means that it is running at the default value.

Hi Cheryl

I can live with that if I could extract the default params.

Hi Paula,

sysdef lists most of them but some don't agree with the values reported by sam.
I don't know if this is a 'bug' or if it as already been documented (or patched) somewhere.

Best regards,

Dan

PS: You're right, /stand/system only lists the non-default parameters.

Hi Paula:

I use a combination of SAM, /stand/system and 'sysdef'.

As noted, /stand/system doesn't show arameters with defaults, so I usually resort to SAM for viewing these. I alsways keep a hardcopy of /stand/system in my book of hardcopy system configurations.

I wan't aware of the potential for 'sysdef' to vanish -- too bad, it's handy.

The nicest advantages of using SAM is that you can toggle a modification of an individual parameter and see the formula used to compute it from other parameters ('nfile' is a good example). Obviously, another nice feature with SAM is that you have its builtin help for each parameter.

As usual, it's nice to have several tools in the bag. Regards, Jim.

I had a look at SAM log (11.00) and found there

kmtune -l

that lists the kernel parameters.

See 'man kmtune'

Paula,
on a 10.x machine look for defaults here:
/usr/conf/master.d/core-hpux

Paula,
I'd like to thank you, also, for your generosity and attentiveness in assigning points. You just allowed me to earn that cute Wizard's hat.... one of my Christmas wishes :^)

Hi Cheryl

I am greatly honoured that I gave you the final points to get your new hat.

It looks very nice and of course congratulations.

Merry Xmas
