The first half of this year has been an exciting time. The new Informix Data Warehouse functionality was announced by IBM, a new release of Informix was announced, and the International Informix User Group Informix
Conference was held in Kansas City, April
26 to 29. I am sure others have reported on
the conference details so I will focus on the
contest we held to honor the Fastest Informix
DBA. And I will share with you some of
my findings with IBM Informix Warehouse
and data compression in the IBM Informix
Dynamic Server 11.50.UC4 release.
Informix Warehouse 11.50, Informix 11.50.UC4
release with data compression, and an
exciting user conference
Informix
Fastest Informix DBA contest
My company, Advanced DataTools, sponsored a contest to find the Fastest Informix
DBA. I took a simple customer billing process,
added some bad SQL, and added a default
ONCONFIG file with a couple of bad configuration options. The benchmark unchanged took
about 30 minutes to run and I challenged
participants to make it run faster. I knew this
was going to be fun because when I tried this
out on my staff the week before the conference, they could not stop running the benchmark. It became an exciting game to make it
all go faster–even I got hooked into finding
different ways to get it to run faster! We gave
each participant about 45 minutes to:

The grand prize was an Apple iPod touch
or the Fastest User DBA, who had to be a
paid attendee at the conference (or conference speaker or volunteer, at the discretion
of the judges), not a consultant, not an IBM
employee, and employed by a company using
Informix internally. We also had 10 categories for many other winners (see sidebar,
“Fastest Informix DBA 2009 Winners”).
Congratulations to everyone who partici-ated—this was a blast and I think everyone
had fun and did a great job. They all took an
ONCONFIG file and SQL script and tuned it so
that it would run in less than four minutes.
We are planning to do a podcast or webcast
with the winners to find out how they did
it. I will also use the analysis from how the
winners did it as material for future articles in
this magazine. And we are looking at ways to
do this again, so stay tuned!

Informix Data Warehouse
function release
I have been building data warehouses using
Informix for over 12 years, as it is lighting-fast
for loads and queries. I have built terabyte-sized systems with thousands of users, and
it works great. In April, IBM announced
the Informix Data Warehouse Feature and
Informix Warehouse V11.50. I was in the
beta program for this function and I am
really excited about the new features.
The key feature is the SQL Warehouse
SQW) Design Studio, which allows you
to build data connections to source and
target databases, reverse engineer the source
