A copy of CakePHP’s database configuration
file is found in

Make a copy of this file in the same directory,
but name it
 database.php

PHP AND IBM DB2

PHP has concepts like PDO and PDO_ODBC, and generic
odbc features that will allow you to connect to and work with
DB-2 databases. Generic odbc is the general/procedural way
to connect to. PDO and PDO_ODBC are object oriented ways.
PDO works with native IBM drivers. PDO_ODBC uses odbc
connections to the DB2. For PHP you need to install drivers
to support DB2. I worked with PDO_ODBC to connect to DB-2
databases in IBM iSeries servers. You need to install odbc
db2 drivers for iseries servers. Then in /etc/odbcinst.ini file
you need to mention driver specifications and in
/etc/odbc.ini, you need to mention the odbc dsn name,
database name, and some other parameters to connect to
the database. Though, you may also supply some
parameters in the PDO_ODBC connect method.
