Install Oracle Apps

This Post will Contain broad level steps of Oarcle apps Installation , this is just for Overview or High level step for Installing Apps. For details & exact commands refer to Oracle Installation Guide mentioned at bottom of this post .

Pre Instalaltion Steps

Check System requirement:
Software Requirenet : like ar, ld, make, gcc, make, Xdisplay – (Unix), MS C++, MKS
Toolkit (Windows)
CPU : It depends on Size, no. of Users … ( For Test Installation don’t worry)
Memory : SGA, Concurrent Users ( Usually 2GB should be enough for testing)
Disk Space : 26 GB Application Tier and for database Tier (35GB Production DB,
65 GB for Vision DB )
Once prechecks are done create User ( Single User or Two user ), with Single user will install both application tier and database tier and for Two user user1(oramgr) will install & own Database tier & user2(appmgr) will install & own Application Tier. (If you don’t knwo what is application or database tier please go through my previous post).
Install MS XML Parser 3.0 Service pack 4 (Only if you are installing Apps in Windows)

Start Apps Installation
go to nstallation software ( either mounted on filessystem or Via CD ) & run rapidwiz ( For windows its rapidwiz.cmd)
Use rapidwiz -restart (If your Installation fails anytime in between , Good feature which Oracle incorporated quite late 😉 lucky you are that this option is there )

Installer will ask you some questions regarding system answer them
For Installation Step by Step screens refer Guide mentioned at bottom of this post , chapter 2 page 30 to 57 ( Just 27 pages , Hope its not too much 🙂 )
Post Installation ( Though these are not required for Testing How apps Installation work)
few things which you might want to do after Installation
Update PL/SQL Log and Out directory
Configure DB Init parameter
Login to Apps
Download jinitiator on client PC ( It will automatically prompt to install on client machine when accessing forms)
For full Installation steps please refer guide at

Hi Atul,
Don’t we need to add application.env file to applmgr connexion scripts ?

Atul Kumar says November 14, 2006

Hi agostino,
Could you repeat why you want to do that .

After Install that assumed that environment file is called from user (applmgr ) shell so that all variable’s are set before doing any activity on server .

Hi Atul,

can you plesae help me in installing Oracle Apps in my laptop..I want to know how much disk space is reuired to load the R12 version in to my laptop?

Rk says December 9, 2009

Hi Atul

I have installed oracle apps Vission Instance on windows Xp. The installation was successful.
but when i try to log on to apps it does log in and asks for Jinitatior to install this happens every time i click on any module(system admin )
it keeps on installing the Jinitator but never opened a form.
Can you please help

Atul Kumar says December 9, 2009

@ RK,
Is this 11i or R12 ? It seems there is issue with jinitiator configuration on server or there is problem installing jinitiator on your local machine.

Check version of jinintiator on server and see if that version is installed on your client PC.

If not, search for specific jinitiator version (one on server) and then install it manually and then try

I have oracle 10g install on Oracel enterprise linux 5 and now I want to install Oracle Apps 11i(11.5.10) on the same machine using the the same existing database.

So Can I do this activity. Is there any pre-requirement for oracle apps? and Can you please provide me the steps to install oracle apps 11i on existing database.


Atul Kumar says February 13, 2011

@ Saket,
You can’t use existing database to install Oracle Apps 11i/R12. Install will create database as part of 11i/R12 installation.

If you have Oracle Database running on that machine then I am assuming that you have already done database related prereqs on Linux 5.

Please start installation and revert back in case of any issues.

saket says February 13, 2011


Thanks for your quick reply..

Still I have some doubts.

1. Can I install Oracle Apps 11i(11.5.10) on Oracel enterprise linux 5?
2. Which Database will get insatll with Oracel Apps11i(11.5.10).
3. If I want to use existing oracle Database 10g( for Oracel Apps installation then is there any workaround for that?


saket says March 1, 2011


I have oracle apps 11i(11.5.10) installed with fresh database.

Now I want to create demo data in the same database then what should be the steps.
