HCL Informix® V15.0.0 documentation
Welcome to the documentation for HCL Informix® 15.0.0 and related client tools and products.
Product overview
HCL Informix® is a fast and scalable database server that manages traditional relational, object-relational, and dimensional databases. Its small footprint and self-managing capabilities are suited to embedded data-management solutions.
Installing
These topics describe how to install HCL Informix® database servers, client products, and modules.
- HCL Informix® server
  These topics describe how to install HCL Informix® database servers.
- Client products
  These topics describe how to install HCL Informix® client products.
- DataBlade modules

  - Module Installation and Registration Guide
    This publication explains how to install modules.
    - Installing modules
    - Autoregistration of a standard module in a database
    - Registering with the SYSBldPrepare( ) function
    - Troubleshooting registration problems
      - Exceptions in calls to SYSBldPrepare( )
        If the IFX_EXTEND_ROLE configuration parameter is set to ON, authorization to invoke the SYSBldPrepare( ) function is available only to the Database Server Administrator (DBSA), and others to whom the DBSA has granted the EXTEND role. By default, the DBSA is user informix.
      - Connection problems
      - Preparation failure
      - Registration problems
- Informix® warehouse accelerator
  These topics describe how to install HCL 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.

Registration problems

If fails to register, unregister, or upgrade a module, perform the following tasks:

Check that the permissions on the datablade.bld file are set to read-only. The datablade.bld file is the module shared object file located in the $INFORMIXDIR/extend/datablade.version directory.
Check the log that generated for the operation. If the log has an unexpected error entry, send the details from the log to the vendor of the module.
Try to register other modules: for instance, the modules that ship with the database server. If you can register another module, your problem is probably specific to the module that failed. Read the release notes for that module; some modules have special requirements, such as a named sbspace.
