Tuning and Optimizing RHEL for Oracle Databases

Had a discussion with an Oracle architect about increasing the shared memory limit of Linux for Oracle. Thought I'd blog this link to instructions on Tuning and Optimizing RHEL for Oracle 9i and 10g Databases. As OEL is very similar to RHEL 4, it should apply.
As far as I know, you can increase the shared memory limit of Linux on a bare metal machine with 16GB RAM to a value higher than 4, 8 or even 12 GB. You only need the hugemem kernel if you have more than 16GB of RAM. And it will basically assign a separate chunk of 4GB to kernel space and the rest to user spaces...
