Re: LINUX Kernel Parameter
It's commercialon-free from HP.
You can however install a TRIAL version which should be good for 90 days(?)

Re: LINUX Kernel Parameter
Usually you can find actual kernel params in /proc/sys/kernel.
Particularly, you can check SHMMAX value by:
# cat /proc/sys/kernel/shmmax

Marcin

Re: LINUX Kernel Parameter
Operations of reading or changing kernel parameters?
Utilization of kernel resources?
Serveral reports and statistics you can get using tools like sar or vmstat.
You can also use collectl from sourceforge - I think this should be available as RH rpm package.
Are you looking for a commercial tool, or rather wondering how to implement it yourself?

Re: LINUX Kernel Parameter
with the command 'ipcs -m' you can view all the segments in use.

Re: LINUX Kernel Parameter
Exactly what action you would like to monitor?
==> Utilization of kernel resources
You can also use collectl from sourceforge
==> what does this utility do?
Are you looking for a commercial tool, or rather wondering how to implement it yourself?
==> not exactly a commercial tool since our box is already in production.
Hi Dirk,
Ok its "with the command 'ipcs -m' you can view all the segments in use."
Ok just to add and be more specific with my question,
For LINUX boxes with DB and Oracle client running on it, what are the kernel parameters I should closely monitor? and How should i monitor them?
Answer like that of Dirk:
shmmax => ipcs -m
