These topics describe the functions.
Welcome to the documentation for HCL Informix® 15.0.0 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 modules.
In addition to administering the database server, you can tune performance, replicate data, and archive data.
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.
These topics describe the API and how to use it.
For an open capture session, starts capturing data from the specified log and log position.
Closes a capture session that is associated with the specified session ID.
Stops capturing data for an active capture session.
Ends capture for a specified table.
Returns the error message text corresponding to the specified symbolic error name.
Opens a capture session and creates a session ID.
Restarts data capture from the beginning of the CDC record currently being returned.
Enables or disables full-row logging for a table.
Specifies the data to start capturing from a table.
The Change Data Capture (CDC) records are returned by smart large object read functions and contain the captured data and information about the transaction currently being captured.
The syscdc system database contains tables that store information about the API.
If a function encounters a problem, it returns an error code. Most functions return 0 if they succeed.
Monitors the sessions involved in change data capture.
The Change Data Capture sample program provides an example of using the API to capture and process data.
This topic demonstrates how to use the Informix Change Streams API to create data streams and capture changing data from the server using the Java programming language.

The HCL Informix OLE DB Provider Programmer's Guide describes the software requirements for using HCL Informix® OLE DB Provider, show how to install and configure the provider for your use, and explain how to use Informix OLE DB Provider to enable client applications, such as ActiveX Data Object (ADO) applications and web pages, to access data on the Informix server.
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 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.
