Re: oracle has customers over a barrel

Heck you'll be hard pressed to get SQL Server numbers and they got only one ;-) Stating the obvious: Aix, Windows and Linux are the big three on distributed. Needless to say I doubt SUN is a growth market for DB2 ;-) But to clarify the never ending codebase discussion: DB2 for LUW is DB2 for LUW is DB2 for LUW DB2 for zOS is 100% different server code. Compatibility is achieved on the SQL syntax/semantics level. In V8 a conscious effort was undertaken to align much more strongly. DB2 V8 for z was very SQL heavy. Obviously there is a DB2 for LUW layer ~5%ish (we never counted LOC) with platform specific tuning and low level APIs. Presumably every cross platform product has that. The clients are shared code across DB2s and IDS thanks to the common DRDA protocol.. which btw is used by Oracle as well when federating with DB2 I'm told. As such Oracle is a proper DB2 DRDA client :-) -- Serge Rielau SQL Architect DB2 for LUW IBM Toronto Lab

And these days, I've heard, one can get support for Solaris on Intel/AMD from IBM, HP and other server vendors. That support should not be more expensive than the one for some enterprise Linux flavor. I am about to start testing it. Sorry for OT from serious topics of this discussion. Darko Krstic
