Hi Jan,

Are you searching for something like that ?
- Using SAP NetWeaver with the Oracle Exadata Database Machine: A Best Practices Guide
- SAP NetWeaver and Oracle Exadata Database Machine
Drop me a mail, if you are really interested into real world implementations, references and contacts. I am able to provide you / establish some contacts into the (SAP on) Oracle Exadata back office / pre-sales.
Regards
Stefan
