I have recently started ORACLE APPS DBA (R12) TRAINING with 2 below mentioned courses.

We have learned how to install R12 EBS in our training session. The installation consist on number of DVDs and we need to create a STAGE directory, it requires over 150GB Hard Disk space, 4GB RAM (recommended) and installtion took couple of hours to complete.

I will write complete installation steps in my next post.
