Thanks Sean,
Personally, I don't have a problem re-compiling the kernel, and in fact I always do for my personal machines. However, I needed to write an install procedure for my company to install Linux and Oracle, and I wanted to get around re-compiling, because some of the installers are not that familiar with re-compiling.
So, the other stuff that you mentioned that you re-compile for, is it for Oracle, or just extra stuff. In other words, in order to install Oracle safely, I do not need to re-compile the kernel (RH6.2).
Sorry, I am just being cautious...
Just one more thing, how can I check what the kernel's shmmax is actually set at (in the running kernel); i.e. is it in /proc?
thanks for the help,
