Well your information needs some update.
- On AIX, IBM had no issues selling Oracle, a rival to DB2. - IBM Global Services, a consulting unit was the single biggest sales force for Oracle Installations outside Oracle. In other words, they ended up using Oracle for projects done by IGM-GS more than DB2. This was true some 10 yrs ago. Oracle use to point it out , with glee. - Many years ago I was informed that Enterprise DB was funded by IBM. Don't know how much it is true.
