Is there a command line method to obtain kernel parameters?

[Russ Park]

Here's an email from a user, we are a mostly Tru64 shop, but have a new rp5430 running 11i:

Russ,
The Oracle install guide requests the following HP-UX kernel parameter settings. In TRU64 I can use the "/sbin/sysconfig -q ipc" command to check the existing settings. Doesn't work for HP-UX. Can you check these parameters and update if necessary?

SHMMAX 1 GB
SHMMIN 1
SHMMNI 100
SHMSEG 10

SEMMNS 200

The command is this:

# kmtune

use command kmtune -l

-USA..

[Hai Nguyen_1]

To have more details, run:
# kmtune -l

To add, unlike other flavors, HP-UX doesn't have a kernel parameter called "SHMMIN" as specified by Oracle. So, do not waste your time looking for that parameter.

kmtune or the more archaic sysdef.

Thanks to all for the quick responses, I got what I needed!

BTW, I'm not sure what to do about assigning points when I get 6 of the same answer, do I give freely to all, or just the 1st one that got it?

Hi Russell!

I hate to be the one answering that question, I will like to answer a technical one instead of this one but I have seen so many 10 points on answers that did not resolve the problem. My point here is that you can assign as many points as you want but it is very nice to assign points to every answer. You are the judge, you will have to make the decision on how to proceed. You asked a question and got 6 GOOD answers that helped you to resolve your problem. That's one of the reasons why we are here, to help others.

Attached kmtune.pl is a wrapper that shows not only the parameter and it's value, but also the value in hex, the formula, and the default value of the parameter. pass a part of the name of the parameter you want to examine and it'll show only the matching one's

Maybe the answerer should consider NOT answering exactyy the same as someone earlier did just to get points ?

Jarle, did you look at the posting times? They were all answered within 2 minutes. Most likely none of the above ever could see the other answers before hitting the submit button.

My answer added some value, at least IMHO by adding a script that *uses* the correct answer to be even more usable.

I agree with you that people should read before answering, but in this case nobody has done anything wrong. It only shows how many people have knowledge in this forum.

No points please

Enjoy, have FUN! H.Merijn

Hi,
i know i'm the last, but there is also the *orrid* SAM in text-only format.

In the kernel subsection, tunable parameter, you have:
- standard value
- computed formulas
- description.

If you are not very familiar with hpux it can be helpful.

to start SAM, just digit
sam
at the promt.

HTH,
Massimo
