Installed Desktop version with GNOME

On a Fresh install of Centos 7 I did the following

- Enabled EPEL repository

http://www.cyberciti.biz/faq/installing-rhel-epel-repo-on-centos-redhat-7-x/

# yum install epel-release

# yum update

- Installed Google chrome (not necessary for Oracle Install)

http://www.cyberciti.biz/faq/howto-install-google-chrome-on-redhat-rhel-fedora-centos-linux/

wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

yum install ./google-chrome-stable_current_*.rpm

ORACLE 12c Install

[root@laptopcentos oracle]#

[root@laptopcentos oracle]# cat /etc/hostname

laptopcentos.rakesh.com

Edit /etc/hosts and add the hostname

127.0.0.1 lapcentos laptopcentos.rakesh.com localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

I will later add an entry for my wifi ip and ethernet ip

Leave the SELinux in enforcing mode as well as the firewall enabled

[root@laptopcentos oracle]# sestatus

SELinux root directory: /etc/selinux

Loaded policy name: targeted

Current mode: enforcing

Add the following kernel parameters to the /etc/sysctl.conf

kernel.shmmax = 8269242368
kernel.shmall = 2097152
fs.aio-max-nr = 1048576
fs.file-max = 6815744

net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

apply the changes

sysctl -p

sysctl -a

Specify limits for oracle user in the /etc/security/limits.conf

oracle soft nofile 1024

Create required OS users and groups for Oracle Database.

groupadd oinstall

groupadd dba

useradd -g oinstall -G dba oracle

passwd oracle

* set the oracle password above

Download the oracle install zip files from the Oracle download site

Extract the zipped Oracle Database Software archives (linuxamd64_12102_database_1of2.zip, linuxamd64_12102_database_2of2.zip) to the /stage folder.

unzip linuxamd64_12102_database_1of2.zip -d /stage/

unzip linuxamd64_12102_database_2of2.zip -d /stage/

Modify permissions on /stage

chown -R oracle:oinstall /stage/

Create /u01 directory for Oracle software and /u02 for database files.

mkdir /u01 /u02
chown -R oracle:oinstall /u01 /u02
chown -R 775 /u01 /u02
chmod g+s /u01 /u02

Install required packages:

yum install \
binutils.x86_64 \
compat-libcap1.x86_64 \
gcc.x86_64 \
gcc-c++.x86_64 \
glibc.i686 \
