OGG-01387
Table {0} has no valid key columns, added unconditional supplemental log group for all table columns.
Cause
Informational only. The table does not have a primary key or a unique key, and no KEYCOLS clause is defined for it. Oracle GoldenGate is using all of the columns as a key to ensure uniqueness, except for columns that cannot be used as part of a key. For column types that are excluded, see the Oracle GoldenGate installation documentation for your database type.
Action
None
