Add following lines to set shell limits for user oracle in file /etc/security/limits.conf

oracle   soft   nproc    131072
oracle   hard   nproc    131072
oracle   soft   nofile   131072
oracle   hard   nofile   131072
oracle   soft   core     unlimited

The /etc/hosts file must contain a fully qualified name for the server.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

For example.

127.0.0.1 linux linux.dbaora.com localhost localhost.localdomain

Modify .bash_profile for user oracle in his home directory and add following lines

# Oracle Settings
export TMP=/tmp

export ORACLE_HOSTNAME=linux.dbaora.com
export ORACLE_UNQNAME=ORA11G
export ORACLE_BASE=/ora01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=ORA11G

PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;

alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'
alias envo='env | grep ORACLE'

Packages

Check which packages are installed and which are missing

rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' binutils

compat-libstdc++-33
elfutils-libelf
elfutils-libelf-devel
gcc
gcc-c++
glibc
glibc-common
glibc-devel
glibc-headers
ksh
libaio
libaio-devel
libgcc
libstdc++
libstdc++-devel
make
sysstat
unixODBC
unixODBC-devel
numactl
numactl-devel

You can install missing packages from dvd. Just mount it and install missing packages using rpm -Uvh command from directory <mount dvd>/Packages or by using yum install command.

First option from dvd
rpm -Uvh/ivh libaio-devel*.x86_64.rpm
rpm -Uvh/ivh ksh*.x86_64.rpm

Second option using yum install command. It requires access to internet.
yum install libaio-devel*.x86_64
yum install ksh*.x86_64

Stop and disable firewall

systemctl stop firewalld
systemctl disable firewalld

Edit the “/etc/redhat-release” file replacing the current release information

"example"(Twenty Three)” with the following.

redhat release 6
Add the following line to the “/etc/pam.d/login” file, if it does not already exist.

session    required     pam_limits.so
Add following lines in .bash_profile for user oracle

Create directory structure

ORACLE_BASE – /ora01/app/oracle
ORACLE_HOME – /ora01/app/oracle/product/11.2.0/db_1

mkdir -p /ora01/app/oracle/product/11.2.0/db_1

chown oracle:oinstall -R /oracle01

Secure Linux

Disable secure linux by editing the “/etc/selinux/config” file, making sure the SELINUX  flag is set as follows. It requires REBOOT to be effective

SELINUX=permissive

Install database software

Issue the following command to avoid problems with starting binary installation in

graphical mode

xhost +<machine-name>

--in my case it's
xhost +linux.dbaora.com

Let’s start with database software installation as oracle user.

su - oracle

--unzip software 11.2.0.4
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip

--I defined 4 aliases in .bash_profile of user oracle to make
--administration easier :)

[oracle@linux]$ alias envo cdob cdoh tns
alias envo='env | grep ORACLE'
alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'

--run alias command envo to display environment settings

envo
ORACLE_UNQNAME=ORA11G
ORACLE_SID=ORA11G
ORACLE_BASE=/ora01/app/oracle
ORACLE_HOSTNAME=linux.dbaora.com
ORACLE_HOME=/ora01/app/oracle/product/11.2.0/db_1

--run alias command cdob and cdoh to check ORACLE_BASE, ORACLE_HOME
[oracle@linux]$ cdob
[oracle@linux oracle]$ pwd
/ora01/app/oracle

[oracle@linux db_1]$ cdoh
[oracle@linux db_1]$ pwd
/ora01/app/oracle/product/11.2.0/db_1

--run installation

./runInstall

Post Installation Steps

Edit the “/etc/redhat-release” file to restore original release information.
