Correct. The DB2 II development team obviosuly has Oracle installed to write and test wrappers.
Not needing to know I have no access to those machines. If I had O10g on my laptop no one would belive me that I don't look at the optimizer plans. Plans tell a lot about the optimizer and query rewrite. "Reverse engineering"
If I ran a query on O10g and I run the same query on DB2 I would have a hell of a time controlling my tongue (assuming DB2 would be faster ;-) "publishing a benchmark without Oracle's consent". Lawyers are no fun at all :-(
