PDO_IBM with IDS 11.5

I trying to get PDO_IBM to work with IDS 11.5. I am having a couple of problems. I loaded Zend Core for IBM. On my Windows development box, I can not get pdo_ibm or ibm_db2 to load. The way that Zend Core loads on windows it starts php in fast cgi mode, so I don't see any errors in the error log. The second issue is, I don't see any documentation to show where you can set up the "INFORMIXSERVER" in the DSN for pdo_ibm. I really would like to get this working so I can use Zend Framework.

For anyone having the problem getting the Zend Core for IBM to load on Windows. I had to install Zend Core, then the DB2 client (compact installation) in that order. The other order didn't work, I have no clue as to why. It is a machine that I have been developing with the same XP installation for almost 4 years now, so it could be my box.

I found the documentation to make the connection. It is in Chapter 3 of the Admin guide in the Distributed Relational Database Architecture (DRDA) section.

I found the information in the admin guide chapter three. Under Distributed Relational Database Architecture (DRDA) Communications.
