The Oracle Extractor encountered an Update record in the redo logs for a row array. This type of record usually indicates that In-Memory Undo (IMU) is enabled. When IMU is enabled, undo data is not available in the redo logs. As a result, Data Replication cannot replicate the Update to the target.
Verify that minimal global supplemental logging is enabled. Enabling minimal supplemental logging disables IMU and causes the undo data to be available in the redo logs. Data Replication can then replicate the Update.
