No, I didn't bring the subject up. Someone else did. I was just tyring to set the record straight and be accurate.

I don't quite understand. DB2 for z/OS is a different product than DB2 for LUW, so it doesn't really make a difference if they come out at the same time for a particular version number, since the version numbers on two different products are not comparable.

If you are saying that the Oracle tools are tightly integrated into Oracle, and for IBM they are completely different products, then you have a valid point there. Of course many people use Websphere for non-DB2 databases, and like the fact that it is not tightly integrated with DB2.

As I said before, I don't really think the code base stuff is an issue because Oracle is not a viable option on z/OS for most shops, and Oracle does not run on AS/400, so the fact that there are different DB2 products (different code base) for those platforms is irrelevant when comparing to Oracle. On the platforms that matter (Linux, UNIX, Windows), both Oracle and DB2 have the same code base.

But as I said, I did not bring up the subject, and most of this code base stuff is just a bunch marketing BS of the zealots, IMO. Received on Sun Nov 27 2005 - 23:06:59 CST
