Resending this to the new group ...  

I have been trying to get stored outlines to work. It seems simple enough, but it is working the exact opposite as I think it should. Anyone else use these? I am on 8.1.7.4 on HP-UX 11.00  

In a nutshell, I verify my query is using the correct explain plan. I grant 'create any outline' to the users.  

Then, I do:  

alter system set use_stored_outlines = true  

ALTER SESSION SET CREATE_STORED_OUTLINES=true; select * from edi_monitor_vw;
ALTER SESSION SET CREATE_STORED_OUTLINES=false;  

I can see the outline in DBA_OUTLINES and also in outln.ol$  

If I open another session and run the query, it is NOT using the correct explain plan.  

If I 'alter system set use_stored_outlines = false;' then the query uses the correct plan.  

I also noticed that outline_category in v$sql is NULL. Does this mean that they outline is not being used? I assume not.  

Thanks all,  

John
