Note: This document mustn't be seen as a 10g new feature, but if you want to test the Oracle 10g new features, you probably prefer using Linux as a OS.

For a complete check please download RDA utility from Metalink and test if the OS is ready for an Oracle 10g Installation. .

Here are some Metalink Notes you can use:

250262.1 -> RDA 4 - Health Check / Validation Engine Guide

330344.1 -> Remote Diagnostic Agent (RDA) 4 - Training

To collect information for a 10g installation you have to run the following command:

./rda.sh -T hcve 

In my case after a full fresh Oracle Linux (2.6.9-42.0.0.0.1.ELhugemem #1 SMP  i686 GNU/Linux) installation on a Pentium4 system, I have to do the following (all is done by root ):

1. Create the Oracle Groups and User Account

/usr/sbin/groupadd dba

/usr/sbin/groupadd oracle
/usr/sbin/useradd -m -g dba -G oracle oracle
id oracle

NOTE: 

The User ID and Group IDs must be the same on all cluster nodes (if a RAC will be installed). Using the information from the id oracle command, create the Oracle Groups and User Account on the remaining cluster nodes: 

Example:
/usr/sbin/groupadd -g 501

oinstall/usr/sbin/groupadd -g 502 dba

/usr/sbin/useradd -m -u 501 -g dba -G oracle oracle

2. Set the password on the oracle account:

passwd oracle
Changing password for user oracle.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

3. Create Mount Points

4. Configure Kernel Parameters

5. Setting Shell Limits for the oracle User

6. Configure /etc/hosts (if needed)
