First off I've never used cxOracle or done any PL/SQL from python, but
it looks like you're passing a list of a list to text().

p_array appears to be some sort of cxOracle array, but when you pass it
to curs.execute you wrap it in a new list: [p_array]. Try removing the
parens and see what happens.
