Install Oracle 11G Release 2 (11.2) on Oracle Linux 7 (OEL7)

Posted on May 3, 2014 This article presents how to install Oracle 11G on Oracle Enterprise Linux 7 (OEL7).
Read following article how to install Oracle Enterprise Linux 7: Install Oracle Linux 7 (OEL7) (for comfort set 2G memory for your virtual machine before proceeding with Oracle software installation).
Installation software is available on OTN version 11.2.0.1 or metalink 11.2.0.4. In this installation I’m presenting installation for 11.2.0.4 but for previous version 11.2.0.X it shouldn’t be different.

You need to install missing from dvd. Just mount it and install missing packages using rpm -Uvh command from directory <mount dvd>/Packages.
NOTE – I’m using x86_64 version of packagesrpm -Uvh elfutils-libelf-devel*.x86_64.rpm
rpm -Uvh libaio-devel*.x86_64.rpm
rpm -Uvh unixODBC*.x86_64.rpm
rpm -Uvh ksh*.x86_64.rpmRun yum install command for missing packages

--example howto install many packages
yum install elfutils-libelf-devel \

Create directory structure for database software
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 /ora01

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=permissiveIn Oracle Enterprise Linux 7 /tmp data is stored on tmpfs which consumes memory and is too small. To revert it back to storage just run following command and REBOOT machine to be effective.systemctl mask tmp.mountInstall database software
Let’s start with database software installation as oracle user.su - oracle
