Abstract
This redbook describes how to define, implement, and document a migration project from Oracle on AIX to DB2 for OS/390. A sample scenario based on a subset of a real application developed in C Language has been used throughout this project. This allowed us to gain first-hand experience and gave us a starting point to evaluate alternatives and to extrapolate to more general considerations applicable to a variety of applications.
This redbook will help you plan for and conduct a conversion of your application from an Oracle AIX environment to a DB2 for OS/390 environment. It particularly applies to Version 6 of IBM DATABASE 2 Universal Database Server for OS/390, Program Number 5645-DB2.
It is primarily intended for database administrators and system designers with Oracle AIX and/or DB2 for OS/390 background: several considerations are applicable to the porting of general data and programs from the AIX platform to the S/390 platform.
We start with an introduction to the project and a summary of our conclusions. This will be especially useful for people responsible for deciding and defining the scope of similar projects.
