[WARNING] No master keys in the configuration. Skipping an encrypted record.
The Extractor could not decrypt a record from an Oracle source that uses Transparent Data Encryption (TDE) because you did not open the Oracle wallet for the configuration in the Data Replication Console. The Oracle wallet must be open to get the encoded master keys that are required for decryption processing.
In the Data Replication Console, open the Oracle wallet that contains the required master keys.
