New to the list looking for Codeigniter Guidance.

Hello List!

I searched the archives and saw a few posts on Codeigniter. We are dabbling
in it now and have it installed and working ... sorta. I am unable to get
the database layer working. Would any of you gurus out there have any tips
or a checklist of things that need to be done to get this working?

We are on v5r4 and below is some information I collected:

I downloaded and installed the db2_c driver. I get the following when
trying to load the database connection:

A Database Error Occurred
Unable to connect to your database server using the provided settings.
Filename: core/Loader.php
Line Number: 232

Here is what is in the log:
