The restart token length is not valid for PowerExchange Express CDC for Oracle sessions. This message indicates the correct length. This error might be caused by a CDC configuration error or by incorrect edits to the restart token value.
The CDC session ends abnormally.
If you manually edited the restart token, correct the token value. Also, verify that the PowerExchange configuration for the CDC session is correct, including the referenced PowerExchange instance and CAPI_CONNECTION statement. Then start the CDC session again.
