Stored outlines = plan stabilization

Fedock, John (KAM.RHQ)

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
