The Copy results in “EXP-00107 Feature (feature_name) of column column_name in table owner.table_name is not supported. The table will not be exported.” (4330864)

When running copy, it fails with the following error showing up in copy server log (sync svr log):

10181 17/12:57:35 WARNING:SyncLogMonitor:3: Error/Warning Detected: EXP-00107: Feature (feature_name) of column column_name in table owner.table_name is not supported. The table will not be exported.

Since Copy uses Oracle Export/Import utility, it will not be able to sync the target table due to the unsupported feature in Oracle Export/Import.

As a workaround, try one of the following:

Run repair to sync the table

OR

Run Oracle Data Pump Export to manually sync the table.

Please refer to Knowledge Article 125531 for manual way to sync a replicating table using Data Pump Export.
