Expertise in Oracle Apps...

Well, most of the oracle DBAs are very much interest in learning Oracle Applications 11i or R12. For that, if you have a laptop with 3GB RAM and a spare external hard disc with min 350GB can start this practice. If you are thinking of Linux, VMWare workstation will do the trick to you. Anyhow I am not going into that area in this post.

First of all  you need to download all related package from e-delivery
http://edelivery.oracle.com/
(Now only R12.1.1 donwload avaliable there)

Once downloaded your required software package, start with Oracle Apps Documentation.

All the information available for Applications Releases 11i and 12 from this link
http://www.oracle.com/technology/documentation/applications.html

  




You must read the following documentation before start with oracle applications

1. Oracle Applications Concepts
2. Oracle Applications Installation Guide: Using Rapid Install
3. Maintaining Oracle Applications Documentation Set
4. Oracle Applications System Administrator's Documentation Set
5. System Administrator's Guide - Maintenance

Once you get familiar with the architecture and the different components of Oracle Applications, consider the following:

• Install oracle Apps by yourself.
• Startup/Shutdown Applications
• Set up users/responsibilities/printers/Concurrent Managers etc..
• Practice Cloning and backup procedure
• Apply all kind of patches
• Practice AutoConfig to manage system configurations
• Try to Upgrade Database/Application tiers

If you are Database OCP holder, you can go for certification directly otherwise go for Oracle Apps training if you can afford it, and/or get the certifications. The certification track details available from the below links.
