SHMSEG Kernel Parameter Won't Change

[jenica]

Hi All,

I am trying to change the SHMSEG kernel parmater in Unixware 7.1.1. The default it 6 and I need to set it to the max which is 15. I ran this command:
/etc/conf/bin/idtune SHMSEG 15
/etc/conf/bin/idbuild -B
shutdown -y -g0
When the system comes up I ran the command to display the status: /etc/conf/bin/idtune -G SHMSEG and it says the current value it 15. But when I run: sysdef -i it still says 6 and my application won't work.

Any ideas would be very much appreciated!
Thank You!
Jenica

Did you try idtune -f -c SYSSEG 15?

Hi Fabber,

I just tried: /etc/conf/bin/idtune -f -c SHMSEG
and rebuilt the kernel and rebooted.

sysdef -i still reports 6.

??

any thing else I can try?
Thanks for your help

You need to put value 15 after SHMSEG.

i.e. .../idtune -f -c SYSSEG 15

Ya, but accidently left it out of my last post.

Still doesn't seem to want to change.

Thanks

What do you have in the following files?

/etc/conf/cf.d/stune
/etc/conf/cf.d/stune.current

Should look something like this:

# pg stune
NUMREGPT 256
NUMSCOPT 32
RSTCHOWN 0
CONSOLE_SECURITY 0
SHMMNI 200
SHMSEG 15
SHMMAX 1300000
# pg stune.current
NUMREGPT 256
NUMSCOPT 32
RSTCHOWN 0
CONSOLE_SECURITY 0
SHMMNI 200
SHMSEG 15
SHMMAX 1300000

Thanks again for all your help!

The only thing I did different from you is instead of using shutdown, I did an init 6. and mine changed no problems.
