Trigger an alert mechanism whenever a DML transaction is captured in between 2 DDL transactions on the same table

If we run a DDL-DML-DDL scenario and update the metadata of the table using dmreaddtable command and resume mirroring, the data is getting mapped incorrectly.

This has been observed where the datatypes are similar and CDC starts capturing data without any events. This is dangerous as the data gets captured incorrectly and it doesn't indicate when we should rightfully perform a Full Refresh on the affected table.

All I ask is to generate a warning event or a fatal event whenever we face a DML between DDL scenario; which should then be taken as a cue for Full Refresh activity.


A Support case TS011462520 was raised already and an agreement was reached to raise an Enhancement request

    IBM Update: Thank you for submitting this request. At this time, CDC does not support heterogenous DDL. Therefore, we cannot add an alert for an intermediary action between DDL transactions.
