  - Installing Informix®
    The Informix® Installation Guide describes how to install, configure, and initialize the HCL Informix database server.
    - Preparing for installation
      Before you install Informix® database server products, you must prepare your system and plan for choices that you must make during the installation process.
    - Running an interactive installation
      You can install the Informix® database server by running the interactive installation application. You can choose a typical or a custom setup.
    - Running non-interactive installations
      You can run non-interactive installations after you first run an interactive installation during which you create an installation template.
      - Preparing a response file
        Before you run a silent installation, you must run an interactive installation to create a response file. The response file contains information about how to install the database server on other computers that have the same basic type of operating system: either a UNIX operating system (including Linux and Mac OS X), or a Windows operating system.
      - Running a silent installation
        You can run a silent installation command that does not require interaction.
    - Installation command syntax
      You can include options to the installation command when you run the command from the command line.
    - Installation troubleshooting
      Installation log files and return codes can provide helpful information about a completed installation or help you identify problems encountered during an installation attempt.
    - Creating a database server after installation
      You create a database server by setting mandatory database server properties and then starting the database server.
    - Stopping and starting the database server
      Various configuration tasks require you to stop and then start the database server. Shared memory is initialized every time that the database server starts.
    - Microsoft failover clustering support (Windows)
      HCL Informix® database server supports Microsoft™ Failover Cluster (known as Microsoft Cluster Server, or MSCS, in earlier Windows™ releases). That built-in feature of the Windows operating system can automatically detect and respond to server or application failure, and can balance server workloads.
    - Multiresidency
      Multiple residency refers to multiple database servers and their associated shared memory and disk structures that coexist on a single computer.
    - Removing or modifying Informix® installations
      You can remove Informix® products.

Running non-interactive installations

You can run non-interactive installations after you first run an interactive installation during which you create an installation template.

A silent, or unattended, installation requires that you create a response file, copy the product installation files and the response file to the target computer, and then run the silent installation command. The response file acts as a template for the silent installation.

UNIX, Linux, Mac OS X: A scripted installation requires that you copy an existing product installation directory to the target computer and run a script.

If you use Enterprise Replication or high-availability clusters, you can create a server clone from a snapshot of an existing database server with the ifxclone utility.

If you plan to embed Informix® products in your application, you can use one of the following methods to deploy the database server:

You can use the deployment utility to deploy snapshots of preconfigured database servers on one or more computers. A snapshot is an image of a database server that includes the installation directory, configuration settings, and any data spaces that are associated with the instance. The installation can be a working instance, or an installation that you set up as a template from which to deploy the instance on other computers. You can use the deployment assistant to customize the snapshot.
Linux: You can run an RPM installation to create an RPM image of a customized database server installation, and then deploy the image through a silent installation.
