The purpose of the assessment questionnaire is to gather metrics for evaluating the technical
feasibility of the application conversion to DB2 10.5 for Linux, UNIX, and Windows. The IM Data
Ecosystem Team will use this information for the sole purpose of preparing an assessment of
the application conversion efforts. We greatly appreciate your best effort in completing the
questionnaire.
This document will be treated as Confidential once completed

Additional comments about the database environment:
5 – Additional Code Requests
Application SQL statements
Please provide some representative samples of complex
or critical SQL statements that are used within the
application.
Database scripts
Please provide any sample database scripts (application,
administrative, maintenance, etc.) that will require
special consideration.
6 – Database DDL and PL/SQL
In order to complete the conversion assessment for both the application and database, details about the source Oracle
database structure must be reviewed. The IBM Database Conversion Workbench (DCW), a no-charge plug-in that adds
database migration capabilities to IBM Data Studio, can be used to extract the Oracle DDL and SQL/PL, as well as
produce compatibility evaluations.
Visit http://ibm.co/ibmdb2dcw to download DCW and the Oracle to DB2 Conversion Guide. The Conversion Guide provides
detailed instructions on how to setup DCW, extract DDL and SQL/PL, as well as how to generate a compatibility evaluation report.
Please return this completed questionnaire with either the Oracle database object extract or compatibility evaluation report.
If you have any questions, please contact the IBM consultant that provided this questionnaire to you.
