Hi Joshua,

Yes – the create_sql_profile.sql script in the post uses the hints stored in the other_xml field of v$sql_plan to create a SQL Profile that usually forces a statement to use the plan from which the hints were extracted.

Hi Kerry,
Was wondering if you have used the plan_table to create sql profile before

Here’s one way to get around those annoying ora-22992 errors when you try to create a profile in a local database using sql text and outline hints from a remote database:

drop table perfstat.junk_pjk_olhints
/

create table perfstat.junk_pjk_olhints
as
select
other_xml
from
dba_hist_sql_plan@&&3
where
sql_id = ‘&&1′
and plan_hash_value = &&2
/

drop table perfstat.junk_pjk_sqltext
/

create table perfstat.junk_pjk_sqltext
as
select
sql_text
from
dba_hist_sqltext@&&3
where
sql_id = ‘&&1′
/

Then run a local create profile script that references the two local junk tables to get hints and sql text to be used in your profile. I did this a few minutes ago, worked ok, the sql profile is created locally, now I need to get developers to run the problem form to see if the problem query is fixed by the profile.

Thanks for this blog.

Hi,

I have 2 PLAN_HASH_VALUE for the same sql_id , the cost is the same , but the Elapsed Time (ms) and CPU Time ( ms )
is diferent , the optimizer is choosing the wrong PLAN_HASH_VALUE ( with diferent sql plan )
How can I force ( may be HINT ) the sql to go with the correct sql plan?

thanks.
