I started this blog 9 years back with first post as How to become Oracle Apps DBA (back then it was 11i) and with 225 comments, this is still the most common question I get in mail or on this blog.
We are starting our new batch for Oracle Apps DBA training (R12.2) from August 8, 2015 and first thing we cover is Architecture of Oracle E-Business Suite. If you are learning (getting trained) on Oracle E-Business Suite on your own then first thing you should learn is Architecture of Oracle Apps.
As shown below Oracle E-Business suite is Three Tier Architecture
a) Database Tier : With Oracle Database where data resides
b) Application Tier : With Application & Web Server where business logic resides
c) Client Tier : browser based client from where end user access application
Note: Till Oracle E-Business Suite R12.1 (prior versions include 12.0 & 11i), Application Tier uses 10g Application Server (or 9 for some versions of 11i). From Oracle E-Business Suite 12.2 onwards Application Tier is deployed on Oracle WebLogic Server as application Server.
You can get more information on Architecture of Oracle E-Business Suite in Concepts Guide or learn it from our expert team by registering to Oracle Apps DBA Training (starting on 8th August) where Day1 covers
