Welcome to the forum - I hope you will both learn and contribute (as I try to do, with varying degrees of success). Please read our OraFAQ Forum Guide and How to use [code] tags and make your code easier to read

About PGA, I would think your best technique would be to use the alert system. Configure an alert (with dbms_server_alert) on metric 5003, "PGA Memory (Session)". If you have Enterprise Edition licences, you can report it automatically whenever your threshold is crossed, otherwise you'll have to write your own alert handler.
