The triggers can be looked for in USER_TRIGGERS or (I think) in ALL_TRIGGERS. For stored procedures, you could do something like

select owner from all_objects
where object_type = 'FUNCTION'
and object_name='ApplyHalfLifeToStock';

(Maybe object_type must be replaced by type!  As I'm writing this at home, I have no Oracle to check.  Use descrive all_objects :-)

Eventually you would prefer user_objects.

If you want to get the definition of the function, you should have a look on all_source or user_source.
