Symptoms

Trying to import a table that contains VARCHAR2 columns from a single byte character set database to UNICODE fails with ORA-1461.
Things tried to alleviate the situation:
1. Precreated the table with NLS_LENGTH_SEMANTICS on CHAR
2. Creating the table with LOB or LONG instead of VARCHAR2 for the larger columns do not always help in solving the situation.
