Introduction:

Briefly the installation and configuration steps for Oracle Applications R12 are as follows:
1)Install linux on the server with appropriate mount points(partitions)
2)Perform the configuration steps required for Applications installation
3)Create a stage area for installation
4)Complete the installation steps
5)Perform the post-installation steps
6)Startup and shutdown steps

1) INSTALLATION OF LINUX

f. On the next screen,choose manually partition option and click Next
g. Give the mount points for filesystem as(Depending on your HardDiskDrive Capacity):
/ (system) 20-30GB ext3
/oraAPP (Application Tier) 120-180GB ext3
/oraDB (Database Tier) 140-200GB ext3
/stage (R12 dump) 45-60GB ext3
swap (temp) Double the RAM- swap
h. Click Next to accept the mount points
i. Click Next to accept the boot loader
j. Enter a hostname,ip address,netmask,gateway information on the next screen and click Next (or directly click next -the details can be entered even after installation)
k. Choose No firewall and SELinux as disabled on the next screen and click Proceed

p. The installation starts after formatting the partitions.Take out the DVD from the drive and Click Reboot.
q. On first startup answer the questions and click Next and Finish.
r. Congrats,That finishes the installations steps for LINUX.

2. PRE-INSTALLATION STEPS FOR ORACLE APPLICATIONS

a. Login as root user open the terminal and type 'netconfig' to specify ipaddress and other network information.
b. Download the patch 4198954 and unzip the patch
c. Go to the unzipped folder and install the 2 packages.
# rpm -ivh package_name
d. Edit the hosts file in /etc folder using vi editor.....enter the following line,save and quit
192.168.1.192 host.domain.com hostname
(your ip) (relevant address) (your host)
e. Type 'service network restart' ...OK has to be returned on all lines.
f. Edit /etc/sysctl.conf to edit the kernel parameters required for Applications
vi /etc/sysctl.conf
# semaphores in kernel.sem: semmsl semmns semopm semmni
kernel.sem = 256 32000 100 142
kernel.shmmax = 2288490188
kernel.shmmni = 4096
kernel.shmall = 3279547
fs.file-max = 327679
net.ipv4.ip_local_port_range = 1024 65000
kernel.msgmax = 8192
kernel.msgmni = 2878
kernel.msgmnb = 65535
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
g. Link and move the following files.....Type the following commands at # prompt
mv /usr/bin/gcc /usr/bin/gcc323
mv /usr/bin/g++ /usr/bin/g++323
ln -s /usr/bin/gcc323 /usr/bin/gcc
ln -s /usr/bin/g++323 /usr/bin/g++
h. Edit /etc/security/limits.conf and add the following lines
* soft nofile 4096
* hard nofile 65536
* soft nproc 2047
* hard nproc 16384

options attempts:5
options timeout:15
j. Edit /etc/profile and add the following lines ,save and quit
export TEMP=/tmp
k. Add users and groups by typing following commands at # prompt
#groupadd dba
#groupadd oinstall
#useradd -d /oraAPP -s /bin/bash -g dba applmgr
#useradd -d /oraDB -s /bin/bash -g dba oracle
l. Set passwords for the users created. Type
# passwd
and give the password when prompted.
m. Change ownership of directories to the user who will install the Application.
#chown -R applmgr:dba /oraAPP /oraDB /stage
Reboot the System
n. Type 'xhost +' at root prompt to enable Gui display for other users also.

3) CREATION OF STAGE AREA FOR INSTALLATION
a. Insert the first DVD labelled Start Here -Disk1 DVD
b. Run the following command
$/media/cdrecorder/Disk1/rapidwiz/perl adautostg.pl
c. Give the target directory name as /stage.
d. Press Enter key to accept default y to Automount
e. Enter the mount point as /media/cdrecorder
f. Press Enter to stage Oracle Applications
g. Insert the DVDs as and when prompted.

4) INSTALLATION PROCESS
a. Login as applmgr and change directory to /stage/StageR12/StartCD/Disk1/rapidwiz
b. Run Rapidwiz ...Type './rapidwiz' and press Enter
c. A screen appears which takes you through the installation steps .....Click Next on first 3 screens.
d. Enter the CSI number, Metalink account and country and click Next
e. Choose create new configuration and Click Next
f. Choose a port pool and Click Next

As root user type #chown -R oracle:dba /oraDB
b. Set the environment by entering the following line in .bash_profile as applmgr user at home directory
vi .bash_profile
. /oraAPP/apps/apps_st/appl/APPSPROD_dev.env
('PROD' is Database SID and 'dev' is the hostname specified during installation)
Save and Quit
c. Run the command '. .bash_profile' at applmgr's $ prompt
d. Switch user to oracle and set the environment by entering the following line in . bash_profile at home directory
. /oraDB/db/tech_st/10.2.0/PROD_dev.env
Save and Quit
e. Run the command '. . bash_profile' at oracle's $ prompt.
f. Congrats,Here Ends the Installation steps for Oracle Applications R12 on Linux .
