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.

  - Installing Informix®
    These topics describe 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.
    - 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.

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 14.10 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 DataBlade® 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.

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.

Important: During setup of the Microsoft™ failover cluster environment, stop the database server before you shut down the operating system to avoid data loss.
