A. Before start installation:

1. The installation of  E-Business Suite R12.1.1 needs, secure Linux disabled and the following package groups installed:

• X Window System
• GNOME Desktop Environment
• Editors
• Graphical Internet
• Server Configuration Tools
• Development Tools
• Administration Tools
• System Tools

I strongly suggest , choose  “install everything” option while you are making Redhat Enterprise Linux installation. Its little hard to try install-add some rpms and other tools on Redhat Enterprise Linux.In this article, i assume that you have been installed everything.

2.The installation size of Oracle E-Business Suite R12.1.1 is:

• 90 GB for a fresh install with a production database:

Application tier file system – 35 GB (For HP-UX Itanium 50 Gb)
Database tier file system – 55 GB

• 243 GB for a fresh install with a Vision Demo database.

Application tier file system – 35 GB
Database tier file system–208 GB (For HP-UX Itanium 210 Gb)

3. Create stage area folder:

You need to setups file for can make Oracle E-Business Suite R12.1 installation. You can use edelivery.oracle.com site for can download Oracle E-Business Suite the lastest version.

Oracle E-Business Suite R12.1 setup files almost have 50 GB size(with NLS patch)

You can create stage folder by following:

Oracle E-Business Suite R12.1 installation manual – Page 1-14 Setting Up the Stage Area

Mainly;

Put all the files under one directory (i.e. /data/R12stage), and extract all the files under the same directory and give it to 777 permission

For instance:

[root@test]# mkdir /data/R12Stage

[root@test]# chown –R 777 /data/R12Stage

[root@test]#  cd /data/R12Stage

For  Start Here DVD create below:

mkdir startCD

For APPL_TOP DVD create below:

mkdir oraApps

For RDBMS DVD create below:

mkdir oraDB

For Tools DVD create below:

mkdir oraiAS

For Databases DVD create below:

mkdir oraAppDB

Before start to  installation, i strongly suggest check below:

B. Installation steps preparings:

1. Edit Host file:

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

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

Example:

[root@test]# more /etc/hosts

127.0.0.1       localhost.localdomain   localhost

Open your hosts file wiht editor(I will use vi editor in this article),put your info in this file and save it. In this article my localhost will be test, my localdomain will be helios.com

PS: If you are using standalone server or pc you can give use any domain name you want. But if your server or pc on any domain you must use localdomain.

[root@test]# vi  /etc/hosts

127.0.0.1       localhost.localdomain   localhost

10.100.x.x     test.helios.com  test

2. Set Kernel Parameters:

Add following line in end of the  /etc/sysctl.conf file.

[root@test]# vi  /etc/ sysctl.conf

#R12.1.1 kernel settings

kernel.shmall = 2097152

kernel.shmmax = 4294967295

kernel.shmmni = 4096

# semaphores: semmsl, semmns, semopm, semmni

kernel.sem = 256 32000 100 142

fs.file-max = 327679

net.ipv4.ip_local_port_range = 10000 65000

net.core.rmem_default=262144

net.core.rmem_max=262144

net.core.wmem_default=262144

net.core.wmem_max=4194304

#full qualified hostname(format is host.localdomain)  << optional

kernel.hostname   = test.helios .com << optional

#correct domain name !! << optional

kernel.domainname = helios.com << optional

After this steps you must set your new settings wiht below command:

/sbin/sysctl –p

3. Update /var/tmp/.oracle with 777 permissions

chmod 777 /var/tmp/.oracle

4. Edit /etc/security/limits.conf file:

Add the following lines to the /etc/security/limits.conf file:

[root@test]# vi  /etc/ security/limits.conf

* hard nofile 65535

* soft nofile 4096

* hard nproc 16384

* soft nproc 2047

5. Edit /etc/resolv.conf file:

Add the following lines to the /etc/resolv.conf file:

options attempts:5

options timeout:15

6. Check /etc/sysconfig/network files format:

Verify that the /etc/sysconfig/network file is formatted as follows:

HOSTNAME=[node_name].[domain_name]

7. If the /etc/sysconfig/networking/profiles/default/network file exists, remove it.

If you changed any files in the previous steps, restart the system.

8. Create user and group for installation:

[root@test]# groupadd dba

[root@test]# useradd –g dba  –d  /home/appltest appltest

[root@test]#useradd –g dba  -d /home /oratest oratest

We will use appltest to can manage Application Tier and we will use oratest for can manage Database Tier. Our installation folder will be TEST,also our SID will be TEST.

10. Create folder for Oracle E-Business Suite R12.1.1 installation

Firstly,  i want to show you my mount point size of server

[root@test]# df –h

Filesystem	Size	Used	Avail	Use%	Mounted
/dev/cciss/c0d0p6	355G	55G	300G	6%	/data

As you can see i have 300 GB free space, so i will create my stage folder and my installation folder on this mount point.

[root@test]# cd /data

[root@test data ]#mkdir  TEST

In this article i will make Fresh Installation(Normaly, If i will make DEMO installation, I like to call installation  folder  VIS, if i will make fresh installation(TEST or PROD) i like to call installation folder  TEST or PROD)

Give 777 to installation folder

[root@test]# chmod 777 /data/TEST

Option 1:

Create related folder for Application and Database tier(optional)

If we want to put application tier installation folder  together(also database tier instalaltion folder) together we can create 2 subfolders under my main installation folder TEST.

[root@test]# cd /data/TEST

[root@test TEST]# mkdir apps

[root@test TEST]#mkdir db

We must give permisson to our user for can make installation of those folder

[root@test]# chown  –R appltest:dba /data/TEST/apps

[root@test]# chown  –R oratest:dba /data/TEST/db

Option two:

Just create TEST folder and give it 777 and use it for installation and application and db tier’s folders will be created under this main folder.

11. I assume that you will not make installation on server room, you will try to make installation on your local laptop or on your pc. So we need to set our xdisplay settings. If this is your first time on server you need to start vncviwer services,before start sevices please follow below steps:

Open  /root/.vnc/xstartup file with vi and edit it as:

[root@test]# vi  /root/.vnc/xstartup

Delete # from below lines

unset SESSION_MANAGER

exec /etc/X11/xinit/xinitrc

[root@test]# service vncserver status <<if it return  not running result,than

[root@test]# service vncserver start

Starting VNC server: [  OK  ]

If first time you are starting VNCSERVER after your Red Hat installation, than you need to give password can connect from your local machine

[root@test]# vncserver

[root@test]# export DISPLAY=test:1.0

[root@test]#xhost+ << it should return below line

Access control disabled,  client can connect from any hosts

12. Open your vncviewer from your local machine and follow installation wizard (if you dont have this program please download it from http://www.realvnc.com)

C. Installation wizard steps:

When you run vncviewer from your local,than you will see below screens,
