osborne says: June two, 2009 at six:38 pm It’s very common to have numerous boy or girl cursors for one sql_id. Usually they have exactly the same program, but It's not uncommon to possess unique strategies. This occurs usually on account of bind variable peeking. A standard circumstance will be that a cursor will get invalidated by collecting stats. Another time it will get executed, a new cursor gets created as well as the statement receives re-optimized. If your bind variables are diverse, a brand new prepare may end up. I’m guaranteed you will find other approaches This will take place too, but this one particular is really widespread (notably in 10g that is overactive in it’s histogram generation, and underneath Energetic within the sample dimensions it utilizes to create them).

When one shared MS DTC is configured for the whole cluster inside a different resource team it is best to include sqlservr.exe being an exception for the firewall.
Greg Rahn states: April five, 2009 at four:57 pm The most crucial difference between an Define as well as a SQL Profile is surely an Define incorporates a complete set of query execution system directives where a SQL Profile (created by the Tuning Adviser) only has changes (OPT_ESTIMATE / COLUMN_STATS / TABLE_STATS) for cardinality allowing for the optimizer the option to select the Procedure dependant on the additional facts. What this means is an Define usually has the exact same execution plan, but a SQL Profile might not.
This article contains a script that dumps the hints affiliated with a statement inside the AWR tables identified as sql_hints_awr.sql. It is possible to see the way it’s utilized over. You can obtain the same data from v£sql_plan by way of XPLAN While using the hints alternative or directly such as this:
dbms_xplan.display_cursor will tell you if a Profile or Outline or Baseline is being used by a cursor Incidentally. I have not viewed a situation exactly where some executions use a Profile and Other individuals usually do not. Most probably you happen to be seeing youngsters which can be not valid but nevertheless hanging around.

Allow me to again up for just a minute. I posted about Oracle’s SQL Tuning Advisor some time back again. It’s a aspect which was added to Oracle in version 10g. It fundamentally looks a SQL assertion and attempts to come up with an even better execution approach when compared to the 1 the optimizer has picked. Since it is allowed just as much time because it desires to do it’s Evaluation, the advisor can sometimes find superior strategies. That’s because it can actually validate the optimizer’s authentic estimates by running a variety of techniques within a specified program and comparing the actual final results on the estimates. When it’s all accomplished, if it's discovered a much better system, it offers to implement that new system by using a SQL Profile.
If you obtain any mistakes when attempting to create a SQL Profile indicating that there's currently a Profile for the specified text with the first Edition, this is probably The main reason.
