How to install Oracle 10g Release 2 (10.2) for RHEL 5

Question

Hello Guys,
I want to install Oracle® Database 10g Release 2 (10.2) for Linux x86-64 in RHEL 5
Please experience people guide me ... please don't give me http://download.oracle.com/docs/cd/B19306_01/install.102/b15667/toc.htm (Oracle® Database Installation Guide 10g Release 2 (10.2) for Linux x86-64) link i already gone through but it's to much in depth and not able to understand what is that i can use from this.
My Machine is having 12GB RAM and it's 64bit machine.
So please provide me steps that only relate to my oracle installation. I just want to do simple installation without database and my machine not have graphical interface also.
Send me your generic steps that i can run on my machine. if you want information about my system specification please ask.
So please people help me out... i am really thankful to you guys .....

3. Changes to be made to Kernel parameters
After installing above mentioned packages, we need to change some Kernel parameters and make them match to Oracle requirements. Parameters which should be changed are shown below
shmmax     2147483648
shmmni     4096
shmall     2097152
shmmin     1
semmsl     250
semmns     32000
semopm     100
semmni     128
file-max     65536
ip_local_port_range     1024 65000
rmem_default     1048576
rmem_max     1048576
wmem_default     262144
wmem_max     262144
We do all these changes in the /etc/sysctl.conf file by adding these lines to that file:
kernel.shmmax = 2147483648
kernel.shmall = 2097152
kernel.shmmni=4096
kernel.sem=250 32000 100 128
fs.file-max=65536
net.ipv4.ip_local_port_range=1024 65000
net.core.rmem_default=1048576
net.core.rmem_max=1048576
net.core.wmem_default=262144
net.core.wmem_max=262144
Question: What will be my value for this as my system is 64bit so this all parameter is ok if i put all straight ?
----> Setting Shell limits for the Oracle UserTo improve the performance of the software on Linux systems, you must increase the following shell limits for the oracle user:
1. Add the following lines to /etc/security/limits.conf file
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
2. Add the following lines to /etc/pam.d/login file
session required /lib/security/pam_limits.so
session required pam_limits.so
3. In order to use Oracle Software, we need to make a change in “oracle” user’s buffer size and number of opened file descriptors. In order to do it, we add below lines to /etc/profile file
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
Question: this things also i need to change ?
