--
-- Author:      Kerry Osborne
--
-- Usage:       This scripts prompts for four values.
--
--              sql_id: the sql_id of the statement to attach the profile to (must be in the shared pool)
--
--              child_no: the child_no of the statement from v$sql
--
--              profile_name: the name of the profile to be generated
--
--              category: the name of the category for the profile
--
--              force_macthing: a toggle to turn on or off the force_matching feature
--
-- Description: 
--
--              Based on a script by Randolf Giest.
