FTA F_FLA_ARRAY,

I think you may not be able to create such an index on a named arrary type. Can you use a nested table instead, as shown below?
scott@ORA92> CREATE OR REPLACE TYPE f_fla_type AS OBJECT
  2    (abc VARCHAR2(3),
  3       def VARCHAR2(7),
  4       ghi VARCHAR2(15));
  5  /
Type created.
scott@ORA92> SHOW ERRORS
No errors.
scott@ORA92> CREATE OR REPLACE TYPE f_fla_array AS TABLE OF f_fla_type;
  2  /
Type created.
scott@ORA92> SHOW ERRORS
No errors.
scott@ORA92> CREATE TABLE ifc
  2    (id     NUMBER(12),
  3       status     VARCHAR2(1),
  4       fta     f_fla_array,
  5       version NUMBER(3),
  6       source     VARCHAR2(100))
  7    NESTED TABLE fta STORE AS fta_nestedtab
  8  /
Table created.
scott@ORA92> CREATE INDEX nested_tab_ix ON fta_nestedtab (abc)
  2  /
Index created.
