OWB Mapping Conversion
0 likes970 views
The document discusses migrating Oracle Warehouse Builder (OWB) projects to Oracle Data Integrator (ODI) projects using a tool called OWB2ODI Converter. The tool can convert OWB mappings, modules, and data modules to ODI packages, folders, and models. It supports migrating many common mapping operators and patterns between the two platforms, handling issues like mappings with multiple target tables. The document provides examples of how complex OWB mappings involving set operators, pivoting, and temporary tables would be converted.
OWB Mapping Conversion
- 1. From Oracle Warehouse Builder to Oracle Data Integrator fast and safe ®
- 2. SUMMARY 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
- 3. 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
- 4. 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)
- 5. 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
- 6. 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
- 8. KMs CUSTOMIZABLE CHOOSING GRID
- 9. 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…
- 10. OWB & ODI RELEASES COMPLIANCE OWB release >= 9.2 ODI release >= 10
- 11. SOME EXAMPLES OF MAPPING CONVERSION
- 12. Example 1 – MULTI TARGET MAPPING
- 13. 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.
- 14. Example 1 – MULTI TARGET MAPPING ( Converted ) The Package will contain the correct sequencing of interfaces maintaining the native semantic of the mapping
- 15. Example 2 – MULTI STAGING MAPPING
- 16. 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
- 17. Example 3 – SET OPERATOR
- 18. Example 3 – SET OPERATOR ( Converted ) Set Operator is converted using the ODI Dataset feature
- 19. Example 4– PIVOT / UNPIVOT OPERATOR A D&T Customized IKM manage the PIVOT and UNPIVOT behavior
- 20. Example 5 – TEMPORARY INTERFACES
- 21. 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…
