3 Reasons to upgrade to 8.7 Integration with Clear Case Debugger in DataStage Designer Operations Console Each job consumes less resources XML handling Current Designer is unstable

4 DB2 Enterprise stage Complicated setup with cross server mount Replaced with DB2 Connector Stage using tool Easy setup More modern and flexible interface More options

5 Connector Migration Tool

6 POC August 2012 Estimate time consumption Rewrites Migrated to Quite painful, meny rewrites

7 Windows Client does not support Windows 7 Skip poc, do the migration! Keep virtual XP clients until end of project

8 IBM Concierge Offered support during migration project Phone conference October 2012 Check requirements Choosing recommended path Ismigration tool

17 Conclusion Painless installation of server and client Small number of adjustments Performance gain % Time consumption 300 h plus 50 hours for install and config

18 Operations console

19 iKnow Monitoring job progress and server health Evaluate job statistics to improve performance Find slow moving jobs Find errors and warnings

20 iKnow

21 Job performance and hw usage
