OGG-00717
Found unsupported in-memory undo record in sequence {0,number,0}, at RBA {1,number,0}, with SCN {2} ... Minimum supplemental logging must be enabled to prevent data loss.
Cause
Minimal supplemental logging is not enabled, so Oracle may use in-memory undo. This causes multiple undo/redo pairs to be written within the same redo record. Extract does not support these types of records.
Action
Enable minimal supplemental logging. For instructions on how to set logging for Oracle GoldenGate, see the Oracle GoldenGate installation and setup documentation for the Oracle database.
