INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

If your row size is over 32000 bytes. ONLINE-CDC will split the 
CDC record being return, limiting ifx_lo_read() to fetch only 
32000 bytes and the application developer must recognize that 
this is a partial record and fetch the rest of the record with 
another call to ifx_lo_read(). 
 
This behavior is not documented and appears to be a design issue 
with the Informix implementation of the CDC API. 
The only way a developer would know to do this is to reference 
the example provided in the cdcapi.ec

Review cdcapi.ec and when a partial record is retrieved you must 
retrieve the rest of the record with another call to 
ifx_lo_read()

Your application cannot depend on a specific number of records 
being returned by smart large object read calls. The number of 
CDC records that are returned in a read call is not predictable 
and might not be an integral number. If a read call returns only 
part of a CDC record, the next read call 
returns more data for that record. Your application must merge 
the parts of the record that are returned in multiple read 
calls. The Change Data Capture sample program provides examples 
of merging parts of records.
