"Bad clob or varray IN-args: (case %s)"
Cause: When in clob or varray mode, the PL/SQL mappings of OLAP API's
IDL interface methods were executed blindly with null clob/varray
or non-null clob/varray containing garbages.
Action: Do not blindly execute them as doing so does not make sense
unless you understand how OLAP API works internally.
