Introduction General Architecture What do we Need How We Migrate OWB Mapping Supported Operators KMs Customizable Choosing Grid OWB & ODI Releases Compliance Some Migration Examples and Typical Issues

INTRODUCTION

OWB2ODI Converter is a semiautomatic tool developed by D&T to assist the migration of OWB projects into ODI projects OWB2ODI Converter can speed up the migration process 90% of migration’s manual activities can be cut back The conversion can be done either at the customer or in outsourcing, starting from export of the OWB project

WHAT DO WE NEED An OWB .mdl export file of the project to convert An Oracle physical export of all involved target schema.

Note: We don't need data, only the structures (exp…ROWS=N or expdp…CONTENT= METADATA_ONLY)

HOW WE MIGRATE OWB MAPPINGS OWB2ODI Converter can migrate:

OWB Project ODI Project

OWB “data module” ODI Model

OWB Module ODI Folder

OWB Mapping ODI Packages with one or more Interfaces / Temporary Interfaces

SUPPORTED OPERATORS

KMs CUSTOMIZABLE CHOOSING GRID

KMs CUSTOMIZABLE OPTIONS D&T customized KMs can also manage other aspects like:

management of ANALYZE on target table management of the maximum number of errors management of loading HINT management of selecting HINT setting Mapping Update Keys etc…

OWB & ODI RELEASES COMPLIANCE

OWB release >= 9.2 ODI release >= 10

SOME EXAMPLES OF MAPPING CONVERSION

Example 1 – MULTI TARGET MAPPING

Example 1 – MULTI TARGET MAPPING ( Converted )

Since Oracle Data Integrator does not allow a mapping flow to end in multiple targets owb2odi converter generates as many interfaces as the OWB Table Operator Targets.

Example 1 – MULTI TARGET MAPPING ( Converted )

The Package will contain the correct sequencing of interfaces maintaining the native semantic of the mapping

Example 2 – MULTI STAGING MAPPING

Example 2 – MULTI STAGING MAPPING ( Converted )

Also in this example owb2odi Converter generates two interfaces to manage the intermediate loading of the SRC_CITY table

Example 3 – SET OPERATOR

Example 3 – SET OPERATOR ( Converted )

Set Operator is converted using the ODI Dataset feature

Example 4– PIVOT / UNPIVOT OPERATOR

A D&T Customized IKM manage the PIVOT and UNPIVOT behavior

Example 5 – TEMPORARY INTERFACES

Example 5 – TEMPORARY INTERFACES ( Converted )

owb2odi converter generate automatically temporary interfaces to keep the semantic between OWB and ODI in some particular situations like Aggregator, Pivot/Unpivot, Deduplicator, etc…
