Re: Number of problems by platform (was: DB2/400 comparisons with oth er relational databases (specifically Oracle and SQL Server))

I hear that phrase again..."what needs to be done is to perform better testing 
on new releases"

Please contact me offline to discover how we can automate the process of 
testing from Unit testing through to Regression testing for
your AS/400, GUI and web needs.

You've kind of hit that one on the head.  Development versus production.
On one major SQL issue, IF we had done some extensive testing on our
development machine then we should have discovered this months earlier.
However, when we upgraded several production machines that weekend and
noticed the problem on all of them, and then duplicated that on
development, and had the same situation work successfully on a V4R5
machine, then yes, we discovered better testing was in order.  And you know
what, even with all that duplication effort, and IBM able to duplicate it
in the lab, they still forced us to open a consult line contract.  All that
person did was duplicate it, physically walk over to developments office
and slap them silly.

This resulted in a meeting with myself, some key department members and our
VP of IS on what needs to be done to perform better testing on new
releases.

I spent 17 years with a local wholesale paper distributor.  We opened
several APARs over those years (multiple midrange platforms.)  Now that I
work for a software developer, I have never had to open an APAR _here_.  I
have had customers open APARS because something that worked fine here did
not work out there.

This incredibly sophisticated analysis <grin> would seem to indicate that
the larger the operation is, the more chances there are to run into an
unexpected situation.  The developers simply don't have that large and
diverse a database that gets hammered 24x7.  My experience with customer
support bears this out as well.  Our small clients rarely report problems
with our software and almost never with IBM software.  The big ones manage
to find something with every release; some bugs are years old but haven't
surfaced until the right combination of drivers, data and storage
conditions
were met.  It's the big customers who find the PTFable situations, too.

Some of this is because the client is back-level on OS/400 or on PTFs, but
some of it is because it's an IBM bug that takes precise circumstances to
materialise.

My thought for the month.  Good thing, too - I was afraid I wasn't going to
have one at all this month!
