[cx-oracle-users] Two-task protocol error when accessing NVARCHAR2 column

[Hamish L. <ham...@gm...>]

I get the following error when attempting to select an NVARCHAR2 column:

    cx_Oracle.DatabaseError: ORA-03106: fatal two-task communication
protocol error

I understand that ORA-03106 can arise dur to mismatches in character
sets. However the same query succeeds when tried from within SQL*Plus.
The database's character set is US7ASCII and its national character
set is AL16UTF16. The client machine runs Solaris 9.
