how to install oracle 11g in Rhel7 linux GUI

step.1.Create a directory and copy file.

# mkdir /u01/

#linux.x64_11gR2_database_1of7.zip

#linux.x64_11gR2_database_2of7.zip

step.2.unzip the oracle 11g software.

#unzip linux.x64_11gR2_database_1of7.zip 

#unzip linux.x64_11gR2_database_2of7.zip 

Now you have a single Database folder which is have runInstaller file.

Step.3.Edit Hosts File

In the Hosts file you have to fully specify your hostname and your machine IP address.

#vi /etc/hosts

For Example.

<ip address >  <full name of machine >   <short name of your machine>

After update this file press Esc then shif+: then wq  then Enter.

Start configuration to install Oracle 11g R2

Step 4.

Edit /etc/sysctl.conf file and add below parameter in end of this file.

#vi /etc/sysctl.conf

 fs.aio-max-nr = 1048576

 fs.file-max = 6815744

 kernel.shmall = 2097152

 kernel.shmmax = 536870912

 kernel.shmmni = 4096

 # semaphores: semmsl, semmns, semopm, semmni

 kernel.sem = 250 32000 100 128

 net.ipv4.ip_local_port_range = 9000 65500

 net.core.rmem_default=262144

 net.core.rmem_max=4194304

 net.core.wmem_default=262144

 net.core.wmem_max=1048586

After that run below command for applying changes of sysctl file.

#/sbin/sysctl -p

Now Edit /etc/security/limits.conf and add following lines in end of this file.

#vi /etc/security/limits.conf

oracle              soft nproc 2047

oracle              hard nproc 16384

oracle              soft nofile 4096

oracle              hard nofile 65536

oracle              soft stack 10240

Step 5.

Now Edit /etc/pam.d/login file and end following parameter

#vi /etc/pam.d/login

session    required   pam_limits.so

Step 6.

Now install required packages for configuring Oracle Database for installing these rmp using YUM server for yum server configuration see my yum server configuration post.

yum install binutils -y

yum install compat-libstdc++-33 -y

yum install compat-libstdc++-33.i686 -y

yum install gcc -y

yum install gcc-c++ -y

yum install glibc -y

yum install glibc.i686 -y

yum install glibc-devel -y

yum install glibc-devel.i686 -y

yum install ksh -y

yum install libgcc -y

yum install libgcc.i686 -y

yum install libstdc++ -y

yum install libstdc++.i686 -y

yum install libstdc++-devel -y

yum install libstdc++-devel.i686 -y

yum install libaio -y

yum install libaio.i686 -y

yum install libaio-devel -y

yum install libaio-devel.i686 -y

yum install libXext -y

yum install libXext.i686 -y

yum install libXtst -y

yum install libXtst.i686 -y

yum install libX11 -y

yum install libX11.i686 -y

yum install libXau -y

yum install libXau.i686 -y

yum install libxcb -y

yum install libxcb.i686 -y

yum install libXi -y

yum install libXi.i686 -y

yum install make -y

yum install sysstat -y

yum install unixODBC -y

yum install unixODBC-devel -y

yum install zlib-devel -y

yum install elfutils-libelf-devel -y

Now add some group and add a user for Oracle installation.

groupadd -g 54321 oinstall

groupadd -g 54322 dba

groupadd -g 54323 oper

useradd -g oinstall -G dba,oper oracle

passwd oracle

Step 8.

Now create a Directory and change  directory permissions

mkdir -p /u01/app/oracle/product/11.2.0.4/db_1

chown -R oracle:oinstall /u01/

chmod -R 775 /u01/

Step 9.

Now set selinux=permissive

#vi /etc/selinux/config

Step 10.

Now make firewall disabled using setup command. Following below steps.

 #systemctl disable firewalld

Step 11.

Now connect you oracle user using su command then open .bash_profile command and add following command in end of file.

#su – oracle

$vi .bash_profile

# Oracle Settings

 TMP=/tmp; export TMP

 TMPDIR=$TMP;

 export TMPDIR

 ORACLE_HOSTNAME='hostname'

 ORACLE_UNQNAME=db11g; export ORACLE_UNQNAME

 ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

 ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/db_1; export ORACLE_HOME

 ORACLE_SID=db11g; export ORACLE_SID

 ORACLE_TERM=xterm; export ORACLE_TERM

 PATH=/usr/sbin:$PATH; export PATH

 PATH=$ORACLE_HOME/bin:$PATH; export PATH

 LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH

 CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

if [ $USER = "oracle" ]; then

 if [ $SHELL = "/bin/ksh" ]; then

 ulimit -p 16384

 ulimit -n 65536

 else

 ulimit -u 16384 -n 65536

 fi

 fi

Step 12.

Now reboot your pc and login with Oracle user and follow below steps.

$cd /u01/database

$./runInstaller

/u01/app/oraInventory/orainstRoot.sh

/u01/app/oracle/product/11.2.0/dbhome_1/root.sh
