- Change Data Capture API Programmer's Guide
  The Informix® Change Data Capture API Programmer's Guide describes how to program applications to process changed data from HCL Informix databases using the Informix Change Data Capture API.
  - Getting started with the Change Data Capture API
    These topics describe the Change Data Capture API and how to use it.
  - Change Data Capture functions
    These topics describe the Change Data Capture functions.
    - The cdc_activatesess() function
      For an open capture session, starts capturing data from the specified log and log position.
    - The cdc_closesess() function
      Closes a capture session that is associated with the specified session ID.
    - The cdc_deactivatesess() function
      Stops capturing data for an active capture session.
    - The cdc_endcapture() function
      Ends capture for a specified table.
    - The cdc_errortext() function
      Returns the error message text corresponding to the specified symbolic error name.
    - The cdc_opensess() function
      Opens a capture session and creates a session ID.
    - The cdc_recboundary() function
      Restarts data capture from the beginning of the CDC record currently being returned.
    - The cdc_set_fullrowlogging() function
      Enables or disables full-row logging for a table.
    - The cdc_startcapture() function
      Specifies the data to start capturing from a table.
  - Change Data Capture records
    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
    The syscdc system database contains tables that store information about the Change Data Capture API.
  - Change Data Capture error codes
    If a Change Data Capture function encounters a problem, it returns an error code. Most functions return 0 if they succeed.
  - onstat -g cdc
    Monitors the sessions involved in change data capture.
  - Change Data Capture sample program
    The Change Data Capture sample program provides an example of using the Change Data Capture API to capture and process data.
  - Informix Change Streams API for Java
    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.
