-- File name:   sqlmon.sql 
-- Purpose:     Spool a SQL Monitoring report to a local HTML file and open it
--              in your browser.

-- Authors:     Adrian Billington and Tanel Poder

--              
-- Usage:       @sqlmon <session_id>
--
-- Other:       This script will report the latest/newest monitored SQL statement
--              of a provided session.
--              Ideally you should run this script from sqlplus running in your
--              workstation, as this way sqlplus will spool it to a local file
--              (and your local browser can open it)
