- Embedding HCL Informix®
  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.
    - The deployment utility
      The Informix® deployment utility can deploy snapshots of pre-configured HCL Informix instances (with or without data) on one or more computers.
    - The syncsqlhosts utility
      Use the syncsqlhosts utility to manually convert the connection information between the sqlhosts file format and the Windows™ registry format.
    - Removing a snapshot with the deployment utility
      Use the deployment utility to remove a snapshot that was originally deployed by the deployment utility. In addition, you can use this utility to remove the user who owns the installation from the operating system.
    - Deploying Informix® and client products with RPM-based installation (Linux™)
      You can create RedHat Package Manager (RPM) images of a customized HCL Informix® product installation to deploy the products with a silent installation. You can use RPM images to deploy the database server and client products in embedded applications. After you install the database server with an RPM image, you must manually initialize the database server.
  - Informix® embeddability deployment tutorial
    The purpose of this tutorial is to provide steps and scripts needed for silent end-to-end deployment of HCL Informix® on Linux™ and Windows™ using the deployment assistant and the deployment utility.
  - 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.

Removing a snapshot with the deployment utility

Use the deployment utility to remove a snapshot that was originally deployed by the deployment utility. In addition, you can use this utility to remove the user who owns the installation from the operating system.

Before you begin

Windows™: You must have Windows™ administrator privileges to remove the snapshot or remove the user and group objects.

UINX, Linux™: You must have root privileges or be the non-root owner of the installation.

You must have the IDSFILES.txt file in the etc subdirectory of the installation path.

About this task

To remove a snapshot:

Procedure

Run the ifxdeploy command with the uninstallation options on the computer where the snapshot is deployed.

See The ifxdeploy command: The deployment utility for details about the command syntax.

Example

The following command is an example of how to use the deployment utility to remove a snapshot and to display runtime status messages:

Windows™:

ifxdeploy -UNINSTALL -i C:\tmp\informix --verbose

UNIX, Linux™:

ifxdeploy -UNINSTALL -i /tmp/informix --verbose

The following is an example of how to uninstall a snapshot and to remove user informix and the administrative group (Windows) or the user who owns the installation (UNIX, Linux):

Windows™:

ifxdeploy -UNINSTALL -i C:\tmp\informix --deluser

UNIX, Linux™:

ifxdeploy -UNINSTALL -i /tmp/informix --deluser
