ORAD: Change vector value 0xFFFF requires redo SCN and redo SUBSCN to have all 0xFF values in the sequence token.
The sequence token is not valid for PowerExchange Express CDC for Oracle. Its change vector of 0xFFFF is not consistent with its SCN and SUBSCN values. This error might be caused by a CDC configuration error or by incorrect edits to the sequence token value.
The CDC session ends abnormally.
If you manually edited the sequence token, correct the token value. Also, verify that the PowerExchange configuration for the CDC session is correct, including the referenced PowerExchange instance and the CAPI_CONNECTION statement. Then start the CDC session again.
