Introduction General Architecture What do we Need How We Migrate OWB Process Flow Supported Activities Warning Transition Handling OWB & ODI Releases Compliance Some Migration Examples

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

GENERAL ARCHITECTURE

export of schemas (only structures)

Repository

OWB

Process flows

Mappings

ODI Project xml

ODI Topology xml

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 PROCESS FLOWS

Process Flow Modules ODI Folders

Process Flow ODI Package

Fork Activity ODI Load Plan

Sub Process Flow Activity ODI Scenarios Mapping Activity ODI Scenarios

Transformation Activity ODI Procedure Complex Transition ODI Procedure

Warning Transition* “Dummy” ODI

Procedure

* Since ODI does not have a “warning status”, the OWB “warning transition” is handled depending on each client’s specific needs. See next slide

WARNING TRANSITIONS

ODI does not have a “Warning Status” How to manage?

Customer solution agreement? Don’t consider at all?

What we do as default:

create a Dummy ODI Procedure

SUPPORTED ACTIVITIES

OWB & ODI RELEASES COMPLIANCE

OWB release >= 9.2 ODI release >= 10*

*The OWB “Fork Activity” is converted by using the ODI “Load plan” feature that is only available from ODI v.11.1.1.5 onwards
