1. Installing Dependencies
Logging into ROOT and Open Terminal
step1:- sudo apt-get update
step2:- sudo apt-get install gcc make binutils gawk x11-utils rpm build-essential libaio1 libaio-dev libmotif4 libtool expat alien ksh pdksh unixODBC unixODBC-dev sysstat elfutils libelf-dev binutils lesstif2 lsb-cxx libstdc++5


2. some softlinks to start the Installation
step3:- 
echo 'Red Hat Linux release 6' | sudo tee -a  /etc/redhat-release
sudo mkdir /usr/lib64
sudo ln -s /etc /etc/rc.d
sudo ln -s /lib/x86_64-linux-gnu/libgcc_s.so.1 /lib64/
sudo ln -s /usr/bin/awk /bin/awk
sudo ln -s /usr/bin/basename /bin/basename
sudo ln -s /usr/bin/rpm /bin/rpm
sudo ln -s /usr/lib/x86_64-linux-gnu/libc_nonshared.a /usr/lib64/
sudo ln -s /usr/lib/x86_64-linux-gnu/libpthread_nonshared.a /usr/lib64/
sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /lib64/
sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/lib64/


3. Adding oracle user and oinstall, dba, nobody group
Step :- sudo adduser oracle
step4:- sudo addgroup oinstall
step5:- sudo addgroup dba
step6:- sudo addgroup nobody
step7:- sudo usermod -g nobody nobody
step8:- sudo useradd -g oinstall -G dba -p
step9:- password -d /home/oracle -s /bin/bash oracle
step10:- sudo mkdir /home/oracle
step11:- sudo chown -R oracle:dba /home/oracle


4. We need to do changes in startup script
step13:- mkdir /etc/rc.d --> cat >> rc.d
for i in 0 1 2 3 4 5 6 S
do ln -s /etc/rc$i.d /etc/rc.d/rc$i.d
done


5. we will create the directory for installation, and changes it owner to oracle.
step14:- sudo mkdir -p /u01/app/oracle
step15:- sudo chown -R oracle:dba /u01


6. We need to modify the kernel parameter
step16:- echo "#">> /etc/sysctl.conf
echo "# Oracle 11gR2 entries">> /etc/sysctl.conf
echo "fs.aio-max-nr=1048576" >> /etc/sysctl.conf
echo "fs.file-max=6815744" >> /etc/sysctl.conf
echo "kernel.shmall=2097152" >> /etc/sysctl.conf
echo "kernel.shmmni=4096" >> /etc/sysctl.conf
echo "kernel.sem=250 32000 100 128" >> /etc/sysctl.conf
echo "net.ipv4.ip_local_port_range=9000 65500" >> /etc/sysctl.conf
echo "net.core.rmem_default=262144" >> /etc/sysctl.conf
echo "net.core.rmem_max=4194304" >> /etc/sysctl.conf
echo "net.core.wmem_default=262144" >> /etc/sysctl.conf
echo "net.core.wmem_max=1048586" >> /etc/sysctl.conf 
echo "kernel.shmmax=1073741824" >> /etc/sysctl.conf


Note: kernel.shmmax = max possible value,
e.g. size of physical memory in bytes. In my case machine is having 2GB so we are specifying 1GB. Adjust the parameter as per your configuration


7. Load new kernel parameters
step17:- sudo sysctl -p


8. I have to change shell configuration
step18:- cp /etc/security/limits.conf /etc/security/limits.conf.original
echo "#Oracle 11gR2 shell limits:">>/etc/security/limits.conf
echo "oracle soft nproc 2048">>/etc/security/limits.conf
echo "oracle hard nproc 16384">>/etc/security/limits.conf
echo "oracle soft nofile 1024">>/etc/security/limits.conf
echo "oracle hard nofile 65536">>/etc/security/limits.conf


9. need to extract the Oracle Download File1 & File2 both the zip to start the installation
step19:-  cd /home/oracle
unzip linux_11gR2_database_1of2.zip
unzip linux_11gR2_database_2of2.zip


10. Now i will start the installation from /home/oracle/database.
Login as a oracle user
step20:- su oracle


11. Go to the binaries and start the installation as a oracle user
step21:- cd /home/oracle
step22:- chmod 777 -R database
step23:- cd database
step24:- ./runInstaller -ignoreSysPrereqs
