In the 3.2 JDBC connector documentation, flag the following Oracle datatypes as unsupported:

• Domain Types
• Boolean data type
• Vector data type

As with the data types that are not supported for the Oracle connector, (DBZ-9402), to head off questions about the inadvertent omission of any of the unsupported data types, create entries for them in the existing data type tables and then explicitly label them as "not supported".

You cannot use the JDBC sink connector to serialize these types from one Oracle database to another.
