Most of the daily traffic in c.d.i-db2 is related to DB2 UDB which does not reflect the actual distribution of DB2
UDB vs DB2 UDB for 390 revenue. Also note that there is a difference between installed base (that would be most of
the posters in a newsgroup) and new licence revenue (that would be the newbees, if there is any correlation at all).
Oracle marketing is driving to a large extend the point that they have the bigger installed base in RDBMS. Gartner
did not evaluate this (and I haven't seen IBM disputing that fact).
Interestingly DB2 UDB 390 (RDBMS and actively competing with Oracle, like it or not) and IMS are also "installed
base". Just not the one that Oracle likes to be compared against. I wonder if there is a survey on total DBMS
marketshare (recurring revenue, #terabytes, #transactions, ...)
Cheers
