You are way off base. DB2 was first ported from OS/2 to AIX in the early 1990's and was known as DB2/6000. WIndows, Solaris, HP/UX, and Linux support followed in the late 1990's, well before version DB2 Version 8.
The code base of DB2 LUW (Linux, UNIX, Windows) is different than DB2 z/OS and will always be different. The SQL at the DML level is getting very close to 100% compatibility.
Oracle folks who complain about the fact that DB2 code base for LUW is different than DB2 for z/OS or DB2 iSeries (AS400) should note that Oracle is dropping its z/OS product and never had a product for iSeries. Received on Sat Sep 12 2009 - 09:33:45 CDT
