Error Handling of CDC task

[iti-attunity-sup]

Hello Experts

Our customer has upgraded v2022.05 to v2023.11 and encountered the problem below:

In 2022.05, when the following warning occurred, CDC task continued without any errors.

[TARGET_LOAD ]I: Load finished for table 'ADM'.'XXXXX' (Id = 1). 85627944 rows received. 0 rows skipped. Volume transferred 98611582288. (streamcomponent.c:3976)

[TASK_MANAGER ]I: Subtask #1 ended (replicationtask_util.c:591)

However the behavior has changed after upgrading to v2023.11.
After the same warning occurred, it is detected as an error and the table is suspended.

[TARGET_LOAD ]I: Load finished for table 'ADM'.'XXXXX' (Id = 1). 85986652 rows received. 0 rows skipped. Volume transferred 99014228864. (streamcomponent.c:4076)

[TARGET_LOAD ]E: TPT data acquisition failed [1020403] (teradata_endpoint_imp.c:1480)
[TARGET_LOAD ]E: Handling End of table 'REP'.'YYYYY' loading failed by subtask 1 thread 1 [1025000] (endpointshell.c:3069)
[TASK_MANAGER ]W: Table 'ADM'.'XXXXX' (subtask 1 thread 1) is suspended. TPT data acquisition failed; Handling End of table 'REP'.'YYYYY' loading failed by subtask 1 thread 1 (replicationtask.c:3208)

Is there any options to ignore the warnings/errors and continue the task like v2022.05?

Any advice would be appreciated.

Hi @iti-attunity-sup 

I don't see anything in the release notes as to why this was changed, I assume to make users more aware of potential data integrity issues. You can simply unsuspend the table and have it continue but you'll still have data issues on the target - and that doesn't exactly answer your question, you want the task to continue without any manual intervention if I understand correctly. I suspect there is not.

But to get a definite answer, we would need to engage our internal support team - and we don't have a way to elevate issues to them via a community post. Please open a support case to pursue this further.

I hope this helps!

Thanks,

Dana
