I've to present credit score to Randolf Geist for creating me have a re-assessment at SQL Profiles. He commented on my Outlines post last week and encouraged I give his article on SQL Profiles a glance. I did and it seriously got me pondering. One of the things I liked the very best about the publish was that he developed a few scripts to drag the existing hints from an announcement from the shared pool or even the AWR tables , and create a SQL Profile from People hints utilizing the DBMS_SQLTUNE.
@?/rdbms/admin/sqltrpt.sql this sql produces sql_profile from cursor cache but not from awr cache but your scripts won't genaretes report that we cannt see what positive aspects to work with sql_profile?

The Baselines also have a plan_hash_value connected with them, though the Profiles do not. So I’m however not certain just what exactly’s happening with Baselines. They surely do have hints related to them, I’m just not sure yet Should they be employed or not. I’m pondering they don't seem to be – but need to glance a little nearer.
I have examine sql_baselines / sql system administration but am concerned that the absence “sharing” limits its abiltiy to help ie., when there are literals it really is unusable. And I think the good approach has to come back from the currrent surroundings.

Greg Rahn states: April 5, 2009 at four:57 pm The principle difference between an Define plus a SQL Profile is undoubtedly an Define consists of a complete list of query execution plan directives in which a SQL Profile (established through the Tuning Adviser) only consists of adjustments (OPT_ESTIMATE / COLUMN_STATS / TABLE_STATS) for cardinality permitting the optimizer the choice to pick the Procedure dependant on the extra info. What this means is an Outline constantly has the exact same execution prepare, but a SQL Profile may well not.
Try making an Define. They are actually available because at least 9i. You could generate a single very easily on any assertion from the shared pool. Then you can certainly alter the stats any way you prefer along with other statements will utilize them, even so the statement Using the Outline must keep not adjust.
