When installing oracle (10g for exemple) modifications are
need on
kernel parameters in file /etc/sysctl.conf.

Well 
---
This modifications cannot be done directy on kernel
source code?
The kernel source code are prepared for oracle?

I am interest on make this modifications, if this needs.

Tks

These are dynamic values, why would you want to hard code these in to the kernel so you would have to
recompile the kernel to change them.

The SHMMAX value should be tuned to your machine and the SEM values suggested by Oracle are as they say, suggestions.
Any particular reason you would want them hard coded in the kernel? I find the possibility to change them on the fly

quite convenient.

It's far easier to modify /etc/sysctl.conf  and run sysctl
-p to read
in the new values than rebuild a new kernel and reboot.
Using the
sysctl mechanism you don't even have any downtime. If you
want to have
this set up for new installs, simply use sed/awk in a %post
script for
a kickstart file and you can do whatever you want.
