Getting started with the Change Data Capture APIThese topics describe the Change Data Capture API and how to use it.
The Change Data Capture APIThe Change Data Capture API allows external client applications to capture transactional data from HCL OneDB™ databases.
Data for captureYou can capture most HCL OneDB™ data types. You can specify the data to capture at the column level.

Data for capture

You can capture most HCL OneDB™ data types. You can specify the data to capture at the column level.

The following data types are not supported for data capture:

Simple large objects (TEXT and BYTE data types)
User-defined data types
Collection data types (SET, MULTISET, LIST, and ROW data types)

Specifying what data to capture

You specify a table and which columns from that table to capture with the cdc_startcapture() function. You must run the cdc_startcapture() function once for each table that you want to capture. For information about which tables and columns are currently being captured, look in the syscdctabs table.

Ending capture of a table

To stop data capture of a specific table, run the cdc_endcapture() function. After you run cdc_endcapture() function, information about that table is removed from the syscdctabs table.
