RE: Stored Outline

The dba_outlines.used column only shows if it's _ever_ been used - even once. I think what you want to check is the outline_category column in v$sql to see if a given cursor is using the outline or not. If use_stored_outlines=true, the outline is valid, and the query matches exactly, then the outline should always be used regardless of bind variable values.
