SUMMARY
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)
OWB2ODI Converter
Converter
mdl export file
DB
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
