Example of implementation of DBMS_APPLICATION_INFO in Oracle PL/SQL (10g and later)

oracle-plsql-exception-handling.sql

-- This is an example framework of how to implement tracking of package/procedure/function plsql
-- procedural code execution (Oracle) with a built-in package: DBMS_APPLICATION_INFO; the intent
-- is to set this syntax layout up so that developers can have a flexible, customizable syntax
-- to accomplish this task.

-- Look for my project here on Github, the ORA-EXCEPTION-HANDLER. (richardpascual)
