  The Informix® Embeddability Guide describes how to embed HCL Informix in your applications.
  - Overview of embedding Informix® products
    You can embed Informix® products in your applications by taking advantage of customizable deployment options and configurable administration features. You can use the embeddability features in combination with other product features for installation footprint reduction and high-availability clustering to achieve a quicker and easier end-to-end deployment solution.
  - Deploying Informix® software
    The product supports embeddability tools that enable lightweight, faster deployment of the database server and related client programs.

    - Introducing the Informix® deployment assistant
      The deployment assistant is used to create snapshots of HCL Informix® instances and their associated dbspaces, which can be later deployed on multiple target computers using the deployment utility.
    - Introducing the Informix® deployment utility
      You can use the deployment utility to deploy snapshots of pre-configured instances and related dbspaces onto target computers.

      - Creating a snapshot for deployment on Linux™
        The second task in the embeddability tutorial is to create a snapshot of the HCL Informix® install binary files and the dbspaces on the template computer by using the deployment assistant.
      - Silently deploy snapshots on Linux™
        The third task of the embeddability tutorial is to silently deploy the HCL Informix® snapshot.
    - Automating deployments of reduced-footprint Informix® on Windows™
      This section contains information about installing Informix®, creating an instance, using the deployment assistant to create a snapshot of the installation, and silently deploying the snapshots on Windows™.
  - Manage memory in embedded environments
    You can manage memory in embedded environments by enabling the database server to automatically rotate and delete online message log files, configuring the actions that the server takes to continue processing when memory is critically low, and enabling the server to reserve a specific amount of memory for use when critical rollback activities are needed and the server has limited free memory.

Perform Informix® installation and create an instance on Linux™

The first task in the embeddability tutorial is to complete an installation and create the HCL Informix® instance.

Install Informix® on the template computer to prepare the master copy for later deployment. A custom installation is recommended because you can choose the features to install. This is one good way to reduce the footprint of Informix®. Some features are mutually dependent and must be installed with one another. The good news is that the installation application manages these interdependencies.

Tip: You will be able to further reduce the footprint of the installation when you create a snapshot of the Informix® instance with the deployment assistant by clearing features and packages that you do not want to include in the snapshot.

The embeddability tutorial for Linux™ is based on the following installation scenario:

Informix® 14.10 is installed in the default directory /opt/IBM/informix
An instance with the name demo_on is created

Important: The /opt/IBM/informix installation path and an instance named demo_on are assumptions made for the tutorial. You can install Informix® in a directory of your choice and create an instance with the name of your choice.

Note: The deployment assistant ifxdeployassist (DA) is not supported starting Informix Server version 14.10.xC7 and is no longer included with the product.
