As far as I know, with all current releases of Oracle,
determinism is purely for function based indexes.  The
deterministic keyword indicates that the function
values when you created the index are still preserved
when you query it.

Thus the "first" execution was during index creation,
and the "second" execution is during subsequent
queries during which the function does not need to be
executed because it is deterministic.

(Lame eh?)
