Informix Client Drivers

Version   4.10
Last Update   12/1/2016
Statistics   240 meg Setup from IBM.  We are required to provide the entire SDK even though only the ODBC and .NET components are necessary.
Compatibility   Any tool that needs to connect to the Connection 2.1(1) or later database needs the IBM Informix drivers installed to be able to connect.  Each tool that needs it will link to this page and their respective setups will check to see if these drivers are installed first before proceeding.  It's only necessary to install this once on each Windows box you intend to use to run remote Unity Connection tools.

NOTE: Most older tools use the ODBC driver however some of the new .NET tools coming out require the .NET driver.  It's best to install ODBC, .NET and the GLS components from the client install below.  The rest is not necessary, although no harm comes from installing everything.

NOTE: If you install the driver via VPN you might have to reboot the system before it's available for use.  It's best to install at the local console if you can.

Support   Support policy follows the tools that use these drivers.

IBM Informix Client SDK Install 4.10 TC7 for all 32 and 64 bit Windows Systems.  Download Now (ZIP file - unpack and run install)

NOTE: IBM finally updated their install package in recent builds so installing this 32 bit version onto 64 bit operating systems should require only that you run the installer executable found in the zip as administrator - I leave the instructions below "just in case" folks have trouble.  I've tested the 4.10 TC6 install on 64 bit versions of Windows 7, 8.1 and 10 with no issue.


If you are installing the 32 bit version onto a 64 bit OS you might need to prepend the SysWOW64 path temporarily to your %PATH% variable or the install may bark at you.  To do this open a comand prompt - be sure to run "as administrator", go to the folder where the Informix SDK install is at and type:


and then launch the setup from the command line and it should go through.  The same technique will work for Windows 8 installs, however you have to run the setup in Windows 7 compatibility mode because the Install Anywhere package IBM uses does not work with Windows 8.  Here is a short training video showing me setting up the drivers on Windows 8 (5 minute Flash video).

You can find the latest SDK downloads from IBM using this link.  All downloads are free but you do have to register on their site.  Be sure to download the 32 bit version even if you are on a 64 bit OS - all tools are compiled for 32 bit operation.

If you are using Java and need to know the details of using JDBC via the Unity Connection database proxy, this document has the details for doing that form both Windows and Linux environments.


The Informix drivers are used by off box tools that connect to Unity Connection 2.1(1) or later systems via the database proxy service.

The help files for each tool that uses the remote database proxy service to attach to Connection has instructions for how to configure the remote ODBC access from off box.  You must create an account with remote administration access and enabled/activate the remote proxy service before you can use it - out of the box Connection has this disabled for security purposes.
