  - Module Installation and Registration Guide
    This publication explains how to install modules.
    - Installing modules
      - Using a module in your database
      - Installing your module on UNIX™
        How you install your module depends on when it was released; the installation process for modules released after the beginning of 2007 is different from the installation process for modules released before 2007.
      - Installing your module on Windows™
        How you install your module depends on when it was released; the installation process for modules released after the beginning of 2007 is different from the installation process for modules released prior to 2007.
      - Uninstalling your module on UNIX™
      - Uninstalling your module on Windows™
    - Autoregistration of a standard module in a database
    - Registering with the SYSBldPrepare( ) function
    - Troubleshooting registration problems
- Informix® warehouse accelerator

Administering
In addition to administering the database server, you can tune performance, replicate data, and archive data.
Migrating and upgrading
You can upgrade to the 15.0.0 release of HCL Informix® or migrate from other database servers to Informix. Upgrading is an in-place migration method that uses your existing hardware and operating system software. Some changes to the Informix database server can affect upgrading from a previous release.
Client APIs and tools
You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
Embedding Informix®
When you embed HCL Informix®, you can use enterprise-class high-availability and high performance with embeddability features such as easy programmability, a small disk and memory footprint, and silent deployment.
Extending Informix®
Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix includes many built-in extensions that are fully integrated in the database server. Informix also provides modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix.
Data warehousing
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
Designing databases
The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
JSON compatibility
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
Security
You can secure your Informix® database server and the data that is stored in your Informix databases. You can encrypt data, secure connections, control user privileges and access, and audit data security.
SQL programming
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Troubleshooting HCL Informix®
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.

Installing modules

Before you can use a module, make sure your database server and any clients are properly configured.

On UNIX™, you must have these environment variables set properly: INFORMIXDIR, PATH, LD_LIBRARY_PATH, ONCONFIG, and INFORMIXSERVER.

For more information, see the HCL® Informix® Administrator's Guide.

On Windows™, you must have these environment variables set properly: INFORMIXDIR and INFORMIXSERVER. For more information, see the HCL® Informix® Installation Guide.
