Multibyte Character Types
Multi-byte characters are supported as part of a supported character set. If the semantics setting of an Oracle source database is BYTE and the setting of an Oracle target is CHAR, use the Replicat parameter SOURCEDEFS in your configuration, and place a definitions file that is generated by the DEFGEN utility on the target. These steps are required to support the difference in semantics, whether or not the source and target data definitions are identical. Replicat refers to the definitions file to determine the upper size limit for fixed-size character columns.
