So no attempt was made or intended to insult you, IBM, DB2, or anything
else. What was made was a staight-forward statement of fact based on my
years working with DB2
        

Your subjective claims ("low" number of...) were dubious, your single
hard claim (need for C compiler on production box), bogus.

      

Absolutely not. You must recompile on the production box, or should I
add a clone of the production box.
    

Your development environment should contain a suitable clone of the
production box -- the same hardware (but perhaps on a smaller scale),
running the same versions of the operating system and DB2.  In this case,
you develop on the development box, and then just install the final
executables and SQL language elements on the production server, when they're
ready for production.

If your development environment does not have a clone of your production
box, then your production environment is just a mere extension of your
development environment -- a risky proposition, at best -- and will be
subject to the possiblity of disastrous failure, regardless of your choice
of OS or RDBMS.

Great in theory. But consider this ... I want to build an application and sell it to customers at ten different locations.

My choice ... buy my own Windows, AIX, AS/400, and OS/390 machines matching my potential client's environments ... or ... put a C compiler on their box and recompile. It isn't that big a deal ... but it is a fact. And it is a fact that is not true with other commercial RDBMS products. Lets not beat this thing to death. It is just a fact of life with DB2.
