While Full Load is successful, CDC/changes are not replicated to the target.
When tested on CDC/FL task using NULL Target, the changes were not being picked up. No errors are logged. The following entries are seen in the log:
[SORTER ]I: Task is running
[SOURCE_CAPTURE ]I: New Log Miner boundaries in thread '1' : First REDO Sequence is '69520', Last REDO Sequence is '69521'
[SOURCE_CAPTURE ]I: New Log Miner boundaries in thread '1' : First REDO Sequence is '69521', Last REDO Sequence is '69522'
Resolution
Verify the column name length of the tables. Columns with names that exceed 30 characters are not supported by Qlik Replicate and Oracle will not write all supplemental log data in the redo logs.
It is likely that the Internal Parameter "skipValidationLongNames" is set, which ignores if the object name or column name exceeding 30 characters.
To fix the issue, only add tables which do not contain columns or tables names that exceed 30 characters.
Alternatively, the appropriate database parameter must be set to allow more characters. This requires a golden gate license with Oracle.
