As root
1) Check Hardware Requirements
# grep MemTotal /proc/meminfo >= 1Gb
# grep SwapTotal /proc/meminfo
Between 1024 MB and 2048 MB 1.5 times the size of RAM
Between 2049 MB and 8192 MB Equal to the size of RAM
More than 8192 MB 0.75 times the size of RAM
# df -h
400 MB of disk space in the /tmp directory
Between 1.5 GB and 3.5 GB of disk space for the Oracle software, depending on the installation type
1.2 GB of disk space for a preconfigured database that uses file system storage (optional)
To determine the amount of free disk space on the system, enter the following command
2) Kernel Requirements
# uname -a >= 2.6.18-8
3) Disable SELinux or switch it to "Permissive" mode
#/usr/sbin/sestatus
SELinux status: disabled
or
#/usr/sbin/getenforce
Disabled
If you see the previous output SELinux is disabled.
If SELInux is enabled then run :
Commands, as root:
======================
getenforce (returns "Enforcing")
setenforce 0
getenforce (returns "Permissive")
End to restore it to enforcing
setenforce 1
getenforce (returns "Enforcing")

The version of the above packages is the lower needed. So if you are in higher you are OK
e.g
# rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep binutils
binutils-2.17.50.0.6-14.el5 (x86_64)
5) Set the kernel parameters
kernel.shmall = physical RAM size / pagesize (getconf PAGESIZE) -- If the defaults are greater then leave it.
kernel.shmmax = 1/2 of physical RAM, but not greater than 4GB -- If the defaults are greater then leave it.
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 512 x processes (for example 65536 for 128 processes)
net.ipv4.ip_local_port_range =9000 65500
a.) The runInstaller (OUI) checks may expect this to be the old guidance of “1024 65000”. The new guidance from Oracle development is “9000 65500”. Please allow the runInstaller (OUI) to proceed with the new guidance from Oracle development.
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
# vi /etc/sysctl.conf
Set the values and then run :
# sysctl -p
6) Add Oracle user and groups and create the ORACLE_BASE directory for Oracle Software and database.
# groupadd oinstall
# groupadd dba
# useradd -g oinstall -G dba oracle
# passwd oracle
e.g
# mkdir -p /u01/app/oracle
# chown -R oracle:oinstall /u01/app/oracle
7) Set the session limits for Oracle User
Set the following to the /etc/security/limits.conf

oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
Set the following to the /etc/pam.d/login
session required pam_limits.so
Add the following to /etc/profile if Oracle user will use the bash shell.
if [ $USER = "oracle" ]; then
ulimit -u 16384
ulimit -n 65536
fi
As oracle user
# grep MemTotal /proc/meminfo >= 1Gb
# grep SwapTotal /proc/meminfo
Between 1024 MB and 2048 MB 1.5 times the size of RAM
Between 2049 MB and 8192 MB Equal to the size of RAM

net.core.wmem_default = 262144
net.core.wmem_max = 1048576
# vi /etc/sysctl.conf
Set the values and then run :
# sysctl -p
6) Add Oracle user and groups and create the ORACLE_BASE directory for Oracle Software and database.
# groupadd oinstall
# groupadd dba
# useradd -g oinstall -G dba oracle
# passwd oracle
e.g
# mkdir -p /u01/app/oracle
# chown -R oracle:oinstall /u01/app/oracle
7) Set the session limits for Oracle User
Set the following to the /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
Set the following to the /etc/pam.d/login
session required pam_limits.so
Add the following to /etc/profile if Oracle user will use the bash shell.
if [ $USER = "oracle" ]; then
ulimit -u 16384
ulimit -n 65536
fi
As oracle user
8) Login as Oracle and change the .bash_profile
Add the following in order to begin the installation
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=orcl # You can not set the ORACLE_SID if you do not want write now
export DISPLAY=YOUR_XTERM_IP:0 in order to you an X session for the installation
unset ORACLE_HOME
$ . ./.bash_profile
to apply the new settings
9) Put the software for 10gR2 to a desired server directory.
10201_database_linux_x86_64.cpio.gz
10201_companion_linux_x86_64.cpio.gz
p6810189_10204_Linux-x86-64.zip
Unzip the database and run
$ gunzip 10201_database_linux_x86_64.cpio.gz
$ cpio -idmv < 10201_database_linux_x86_64.cpio
$ cd database
$./runInstaller –ignoreSysPrereqs
Then unzip the companion and run
$ gunzip 10201_companion_linux_x86_64.cpio.gz
$ cpio -idmv < 10201_companion_linux_x86_64.cpio
$ cd companion
$./runInstaller –ignoreSysPrereqs
Finally unzip the 10.2.0.4 Patch Set and run (At the time this post was written only the 10.2.0.4 patch was available):
$ unzip p6810189_10204_Linux-x86-64.zip
$ cd Disk1
$ ./runInstaller –ignoreSysPrereqs
10) Create the database
Add the following to the .bash_profile
export ORACLE_HOME=[YOUR_ORACLE_HOME]
export PATH=$ORACLE_HOME/bin:.:$PATH
Run
$ . ./.bash_profile
$ dbca
Create your desired database and you finished
After that run
$ netca
To create a listener
ATTENTION if your host name is more than 32 characters then you are about to have the following situation:
If you have choose to install EM and during its creation you get from dbca
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
then apply the following workaround:
1) Ignore error and continue with database creation
2) After successful finish of dbca do :
Verify the case using sqlplus
SQL> select length(host_name) from v$instance where rownum=1;
LENGTH(HOST_NAME)
-----------------36
Here the length is 36 (>32) and for 10.2 this is a bug and em repository creation fails.
So
a) Make a backup copy of the file
$ cp $ORACLE_HOME/sysman/admin/emdrep/sql/core/latest/self_monitor/self_monitor_post_creation.sql
$ORACLE_HOME/sysman/admin/emdrep/sql/core/latest/self_monitor/self_monitor_post_creation.sql_bak
b) Change the l_host_name variable in self_monitor_post_creation.sql to have 128 characters
The l_host_name variable needs to be changed twice in the script.
$ vi $ORACLE_HOME/sysman/admin/emdrep/sql/core/latest/self_monitor/self_monitor_post_creation.sql
c) Drop and recreate the DB Control configuration files and repository
$ $ORACLE_HOME/bin/emca -deconfig dbcontrol db -repos drop
$ $ORACLE_HOME/bin/emca -config dbcontrol db -repos create
Check your em by using the URL mentioned.
