View kernel params from command line

Yahya Mohammad — Mon, 18 Oct 2010 07:38:29 GMT

Is there a way to view kernel params from the command line as a regular user? I have HP-UX 11.31.

It seems kctune can do this, but I can't find it, what path is it usually installed in?

Hi,

Yes by kctune u can view the kernel parameters on command line in path of /usr/sbin/kctune.

U can refer its man page for more details.

Hope this solves ur query
Dont forget to assign points.

# whence kctune
/usr/sbin/kctune

To list all the kernel parameters:

# kctune
Tunable Value Expression Changes
NSTREVENT 50 Default
NSTRPUSH 16 Default
NSTRSCHED 0 Default
STRCTLSZ 1024 Default
STRMSGSZ 0 Default
acctresume 4 Default
acctsuspend 2 Default
aio_listio_max 256 Default Immed
aio_max_ops 2048 Default Immed
aio_monitor_run_sec 30 Default Immed
aio_physmem_pct 10 Default
aio_prio_delta_max 20 Default Immed

To set value of a parameter
#kctune "Tunnable Parameter" = value

Thanks everyone. /usr/sbin wasn't in my path, and I was looking around in /opt and other places instead of the obvious ones :)

also you can use sysdef; (sysdef - display system definition)

/usr/sbin/sysdef

look man page of sysdef for more;
