Oracle Applications R12 Schema Analysis

Oracle Apps R12 Schema Analysis

Continuing on my series on analysis, here is some of the initial analysis I did after installing Oracle applications R12.  Much of the analysis involves queries to the Oracle data dictionary under the covers.  This analysis is on the sample “database”, VIS, which is actually composed of many schemas.

I also did a fair bit of analysis from a DBA standpoint: tablespaces, logs, processes, DBMS_JOBS, etc.  And other analysis on the unix and middle tier side.  Tuning.  I’ll try to keep it all organized in different posts.

When I’ve started a new position, these are the types of queries I might run on the schemas to get a feel for the systems.  Just how was it made? Does it use PK, triggers, or external code to enforce data integrity?  What are the most important tables?  What are potential performance issues? Any issues?  And so on.

Many of these queries you won’t find the GUIs like SQL Developer, or Toad.  You have to write them yourself.  It pays big dividends to know the data dictionary!
