As an information developer who has documented and completed numerous Informix® installations in GUI mode for over 4 years, I've really liked how the installer has evolved. First, with version 11.10, the custom setup of the installer let you peel away the features of the database server that you did not want. This functionality, known as the deployment wizard, helps you save on disk space when you want to minimize the footprint of the installation. The revised interface also provided a short description of each feature—just enough information to let you know whether or not it was a component that you needed.
Client SDK and Informix Connect are fully integrated into the IBM® Informix Software Bundle version 11.70 installer in such a way that there is no need for separate standalone and bundle media. The major client programs appear in the feature tree in custom setup, so that in one step of the installation process you can exercise your right to exclude whatever client programs and whatever base server features that you don't need. (See the IBM Informix Software Bundle screen capture below.) Unlike previous versions, there is one unified interface after launching the installation of the Informix server with either Client SDK or Informix Connect. No more watching installers of separate products open and close.
Right after you select products and features, the installer puts you back in the driver seat again. You can choose whether the installer should automatically create a working instance of the database server—and if you do, you can opt to specify major configuration parameters yourself or let the installer calculate working configuration settings based on the host environment.
And perhaps the best part is that you can still complete a product installation with the media in less than 30 minutes!
