Developing an SSIS package that uses the Oracle OLEDB Provider on a 32 bit operating system and then deploying to a 64 bit SQLServer installation may result in the following error:
[OLE DB Source ] Error: column "<columname>" cannot convert between unicode and non-unicode string data types.
[OLE DB Source ] Warning: The external columns for component "OLE DB Source" (1) are out of synchronization with the data source columns. The external column "<columname>" needs to be updated.
[SSIS.Pipeline] Error: "component "OLE DB Source" (1)" failed validation and returned validation status "VS_ISBROKEN".
