Step By Step Installation Of Oracle Applications Release 12

STEP by STEP Installation of Oracle Applications Release 12
This is the install process for R12 Oracle applications on LINUX. Assuming that the LINUX is ready with all the rpms and OS settings.
I am doing a multiuser installation on LINUX.
In order to prepare for a multi-user installation, you must first create an oracle user account and an applmgr user account. Both should be created with a default
shell that is compatible with the Bourne shell. Log in as root to run Rapid Install. Then specify the oracle user as the Oracle OS user, and the applmgr user as the
Apps OS user.
Please complete all standard pre-reqs for LINUX install ( Like "/etc/sysctl.conf" for Shared memory and semaphors)
Create Oracle user
#useradd -u 1100 -g dba oraalpha #passwd oraalpha Changing password for user oraalpha. New UNIX password: BAD PASSWORD: it is based on a dictionary word Retype new UNIX password: passwd: all authentication tokens updated successfully. #
#useradd -u 1101 -g dba appalpha #passwd appalpha Changing password for user appalpha. New UNIX password: BAD PASSWORD: it is based on a dictionary word Retype new UNIX password: passwd: all authentication tokens updated successfully.
Create the STAGE area (Stage area is the software location for R12 software)
The script prompts you to choose the components that you want to stage:
Oracle Applications
Oracle Database technology stack (RDBMS)
Oracle Applications database (Databases)
Oracle Applications technology stack (Tools)
APPL_TOP
You should be able to see the following directories. (After your stage location is ready)Software/Disk1/rapidwiz/adautostg.pl : This helps in creating the stage area for your installation.
startCDoraDBoraAppDBoraASoraApps
After your stage area is ready, You can start the installation.Please note that starting with R12 you need not to install the JDK seprately.
Login as root (on GUI , May be a VNC session)
cd /StageR12/startCD/Disk1/rapidwiz Please note : If you want to use an alias (not the actual name of the host machine), use the -servername parameter when you start Rapid Install.
rapidwiz -servername alias rapidwiz -techstack (Can be used to install techstack only)
If install fails in between and you may need to restart it , You can use rapidwiz -restart ========Installation Begins...cd /StageR12/startCD/Disk1/rapidwiz ./rapidwizOracle applications release 12 installation screen 1.

Another important discion to make here. If you want to keep all services on a single node you should do a Single node installation. If you want to spread the services on different boxes you can add another node. In General, The recommonded way is that we should keep the admin and Db server on one node and web/form on another node. This is to get the best perofmance.
