Writing an application to capture data changes
Use the Change Data Capture functions
to control the data capture process. Process CDC records to extract
the data. Query syscdc tables to retrieve the symbolic names
and descriptions of CDC records and errors.
Handling smart large objects
The Change Data Capture API does not directly support the
retrieval of smart large object column data from a captured BLOB or
CLOB row. You must use the DataBlade
API or
client API smart large object read functions to retrieve smart large
objects.
Restarting data capture
You can restart data capture where the last data capture
session ended.
Monitoring data capture
You can monitor the status of data capture by running the onstat
-g cdc command.
