Welcome to the documentation for HCL Informix® 15.0 and related client tools and products.
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.
These topics describe how to install HCL Informix® database servers, client products, and DataBlade® modules.
In addition to administering the database server, you can tune performance, replicate data, and archive data.
You can upgrade to the 15.0 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.
These topics describe the Global Language Support (GLS) feature available in HCL® Informix® products.
HCL Informix® ODBC Driver supports the extended data types.
HCL Informix® ODBC Driver supports the GLS data types.
HCL Informix® ODBC Driver supports additional values for some ODBC function arguments.
ODBC with the HCL Informix® ODBC Driver includes several components.
HCL Informix® ODBC Driver includes a Driver Manager Replacement (DMR) library. The DMR replaces the driver manager on platforms where no driver manager is available.
HCL Informix® ODBC Driver includes the four components.
An application uses the HCL Informix® ODBC Driver API to make a connection to a data source, send SQL statements to a data source, process result data dynamically, and terminate a connection.
Starting CSDK 4.50.xC2 onwards, Informix ODBC driver also supports Connection Pooling capabilities. One may decide to use either Connection Pooling capabilities provided by ODBC Driver Manager or newly added capabilities in Informix ODBC Driver
HCL Informix® products can support many languages, cultures, and code sets. Global Language Support (GLS) provides support for all language- and culture-specific information.
In addition to the standard ODBC functions, the HCL Informix® ODBC Driver also supports the additional functions.
For HCL Informix® Version 10.0 and later, you can implement external authentication through the HCL Informix ODBC Driver.
You can bypass ODBC parsing by using several options.
The SQLGetDiagRecW API returns diagnostic information in the output buffer, where the BufferLength parameter is the length of buffer allocated.
The SQLGetDiagRec API returns diagnostic information in the output buffer, where the error description is for the HCL Informix® error message.
You are likely to improve the performance of single-threaded applications by using the SINGLETHREADED connection parameter. The value is off by default.
HCL Informix® ODBC Driver supports partial implementation of several ODBC features.
These topics explain how to configure a data source (DSN) on UNIX™ and Windows™ for HCL Informix® ODBC Driver.
These topics contain information about the data types that are supported by HCL Informix® ODBC Driver.
These topics describe how to store, create, and access a smart large object; how to transfer smart-large-object data; how to retrieve the status of a smart large object; and how to read or write a smart large object to or from a file.
Rows and collections are composite values that consist of one or more elements.
These topics describe the HCL Informix® ODBC Driver client functions. Use these functions to access and manipulate smart large objects and rows and collections.
Set the CLIENT_LABEL environment variable in CSDK 4.50.xC4 onwards to assign a character string to ODBC client session and identify that character string on the database server. You can use this variable to distinguish one database session from the other.
These topics suggest ways to improve performance of HCL Informix® ODBC Driver applications.
These topics describe the HCL Informix® ODBC Driver error messages.
These topics provide a brief overview of the Unicode standard and shows how it is used within ODBC applications.
Starting with CSDK 4.50.xC4, Informix .NET Core Provider built with .NET Core SDK/Runtime v3.1 is shipped for Windows x64 and Linux x86_64 platforms.
These topics include information about HCL Informix®4GL and SQL.
These topics include information about the translated user interface files for Informix® UNIX™ products, locales, and code set conversion tables
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.
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.
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
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.
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
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.
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.
