KEYCOLS Not Working In GG 12c To Enforce Key/uniqueness

Information in this document applies to any platform.

Symptoms


When doing initial load processing to CDC capture tables, KEYCOLS is not working to enforce the key/uniqueness, duplicate insert records are being created. These are CDC capture tables, just a sequence being used for the primary key, and all records during regular processing are inserted. The issue arises when we do initial load and a record on the source is inserted during that initial load.
