SQL Tuning Advisor says I have old statistics but they were collected today

Hi all,
Oracle 10.2.0.4.0 64-bit
Win 2003 Standard Edition 64-bit
I was looking at some problem code of ours earlier through Enterprise Manager, and decided to use the advisor to see what it recommended about one statement. (Apologies at this point for being 100% on the name of the advisor as I am working in Spanish, but I guess it may be "SQL Tuning Advisor"?)
The recommendations were all to do with gathering optimizer statistics on the various tables and indexes involved as they were "out-dated". I have checked the LAST_ANALYZED columns in DBA_TABLES and they were collected automatically, as always, at 0230 today. The advisor task was run at about 1030.
Has anyone else seen this? Is it a bug? Or is the advisor very intelligent and suggesting that the data in the tables has changed dramatically since 0230 this morning and that yes, those stats really need collecting again?
Regards,
Ados

Hi Niall,
Thanks for replying. My guess was that it was probably doing something based on how much the content of the table had changed, but I didn't know about the 10% threshold. Thanks for that.
However, would it be looking in the STALE_STATS column in ALL/DBA_TAB_STATISTICS and ALL/DBA_IND_STATISTICS to see this?
(This is how I woud do it, however I am a mere mortal, unlike the Oracle advisor.. )
I checked there already and all of the tables and indexes in question have the value "NO".
So I still don't get it

SQL tuning Advisor for old statements

Hi all,
i've identified SQL ID (through snapshots AWR) that make me performance problem. This is a old select statement (Mar 10, 2008) and when i try to run sql tuning advisor, it shows me this error:
"There was a problem creating a SQL tuning task. ORA-13780: SQL statement does not exist. ORA-06512"
I've set AWR for retain 60 days of Snapshot Retention, why i can't run tuning advisor for this statement??
thanks very much for answers.
Andrea

Hi
The problem is that the information of AWR is based on Historical information that Oracle retrieve of historical tables . AWR means Automatic Workload Repository.
But when you execute the SQL tuning advisor task, Oracle needs retrieve the information of sql statement from SHARED POOL.
The Library Cache is a part of Shared pool and contains an area named SQLAREA that stored information of execution plan for sql statements. This memory area is managed by LRU alghoritm.(last recently used) and the error is produced because this sql statement not is stored in this memory area.
When the sql stament not reside in memory Oracle can't build the execution plan and then the error appear

What is this SQL Tuning Advisor's Advice means

HI ,
I am Tuning a query wit hthe help of ORACLE 10 g 's SQL Tuning Advisor.I got the following recommendation .
**Consider removing the disconnected table or view from this statement or add a join condition which refers to it.**
I didn't understand what does this mean.
Can anyone please help me
Thanks,
Pramod.

Simply saying if i apply that profile i will get Good plan.But I want to change the SQL itself rather than applying profile.in that case what can be done.Automatic SQL Tuning deals with this problem with its SQL Profiling capability. The Automatic Tuning Optimizer creates a profile of the SQL statement called a SQL Profile, consisting of auxiliary statistics specific to that statement. The query optimizer under normal mode makes estimates about cardinality, selectivity, and cost that can sometimes be off by a significant amount resulting in poor execution plans. SQL Profile addresses this problem by collecting additional information using sampling and partial execution techniques to verify and, if necessary, adjust these estimates.During SQL Profiling, the Automatic Tuning Optimizer also uses execution history information of the SQL statement to appropriately set optimizer parameter settings, such as changing the OPTIMIZER_MODE initialization parameter setting from ALL_ROWS to FIRST_ROWS for that SQL statement.
If you want to change the SQL, You can re-write the SQL and evaluate the Performance recommendations SQL tuning Advisor.

SQL Tuning Advisor (STA) recommends indexes that already exists?

I have enabled the STA to run twice a week, while we are going live with a new application in a new database. I want to insure we have good performance as the load goes up. I was not involved in the original design, which there not not much of, I've discovered. Since we are licensed for it, it seemed like a safe thing to turn on.
The STA ran last night and the report tells me it looked at 736 SQLs with findings, 143 without findings, and skipped 0.
What puzzles me is that, in the "Statistics Finding Summary", it's reporting stale stats on some tables which I know are up to date, as I ran stats on them yesterday and there were no updates to them.
Worse, in the "Index Finding Summary", it reports indexes needed that already do, in fact, exist.
Is there some reason for this? Is there some way to get the STA to be aware of these and avoid the erroneous findings so that I can concentrate on real ones?
Thanks in advance for any suggestions.

SQL Tuning Advisor evaluates statement using wrong plan_hash_value

The execution plan for one of my SQL statements changed this morning. The statement is in a third-party package. The new plan runs worse than the old plan. I had the SQL tuning advisor evaluate the statement. I ran it three times. Each time it evaluated the original plan, not the new one. I can tell that because the plan_hash_value shown in the advisor's recommendations is the old plan's plan_hash_value. The old plan no longer appears in DBA_HIST_SQL_PLAN. I do not understand why the advisor is using the original plan, nor where it is getting it. It does not show up in Oracle Enterprise Manager either.
Has anyone see this before?
Do you have any suggestions how I can force the advisor to evaluate the new execution plan?
I am running Oracle Database Server 10gR2 Enterprise Edition.
Thanks,
Bill

Following advice given earlier, I ran the SQL Tuning Advisor by executing DBMS_SQLTUNE from within a SQL*Plus session instead of via Oracle Enterprise Manager. The problem I originally encountered in OEM also happened using DBMS_SQLTUNE. Using DBMS_SQLTUNE I specified plan_hash_value => '3657286666' but the results of running create_tuning_task shows that the utility used a different plan_hash_value. See below:
Based on this, I think the problem I originally blamed on OEM's creation of a SQL Tuning Advisor job was misdirected. I now believe that OEM supplied the proper information to the advisor, but the advisor did not correctly use what is was given.
Below is what I submitted when I ran create_tuning_task and execute_tuning_task. Note that the value assigned to plan_hash_value is 3657286666. Following the messages from execute_tuning_task, see the output produced by the execution of report_tuning_task. In EXPLAIN PLANS SECTION heading 1 - ORIGINAL, note that Plan Hash Value = 3541843898.
I submitted instructions to use plan_hash_value 3657286666 but instead it used 3541843898. Why did it do this??????
I have not found a published bug that describes this condition.
Thanks,
Bill

FINDINGS SECTION (1 finding)
1- Index Finding (see explain plans section below)
The execution plan of this statement can be improved by creating one or more
indices.
Recommendation (estimated benefit: 100%)
- Consider running the Access Advisor to improve the physical schema design
or creating the recommended index.
create index EXPTEST.IDX$$_1AE6E0001 on
EXPTEST.SERVICE_EVENTS('EQ_NBR','ASSOC_EQ_NBR');
Rationale
Creating the recommended indices significantly improves the execution plan
of this statement. However, it might be preferable to run "Access Advisor"
using a representative SQL workload as opposed to a single statement. This
will allow to get comprehensive index recommendations which takes into
account index maintenance overhead and additional space consumption.

Hi,
Thanks for your reply,
Creation of SQL Tuning Task failed due to below one,
"to_char(max(r.ts), 'mm/dd/yyyy') viewrequest_lastdate"

The symbol "*" was substituted for "MM" to continue.
Then i have replaced with

Stucked between SQL Tuning Advisor and and SQL statement

Hi,
There is an important query running on my system which consists
MEMBER OF function.
At first place let me explain why i used MEMBER OF,
I am sending a string( eg : #123#124#125) to query and a function converts this string into a number array.
After then I use this number array inside my sql.
The reason I am using this structure, in order to generate a dynamic IN statement inside my sql. (IF you have any other solution that would be great)
The most important point is; when I put this statement to SQL Tuning Advisor the response is only ORA-00932: inconsistent datatypes: expected UDT got CHAR
Any answer will be greatly appreciated.
Thanks

Object oriented stuff almost never provides better performance over relational. You should stay away from MEMBER OF if performance is a factor. Instead of:
WHERE expr MEMBER OF nested-tableI'd test:
WHERE expr IN (SELECT column_value FROM TABLE(nested-table))SY.
expr IN (SELECT COLUMN_VALUE FROM TABLE (CAST (v_type_number_table AS type_number_table)))worked like a charm. i hope tuning advisor will like it as i do.
thanks.

will the rows really be updated just by using the package?Considering DMLs

SQL Tuning Advisor against the session (is it poosible)

My Company customer has observed that there is job that are running longer than expected running(5 days).
They did not gave any information.they want me to run
SQL Tuning Advisor against the session running this job.
can you run sql tunning advisor against running session?
if so how
Please suggest me your valuable tips so that I approach this work properly.
DB = 11g
OS= Solaris 10

SQL Tuning Advisor is run on statements and not sessions. I don't do much with SQL Tuning Advisor, but I'd consider that current running sessions a lost cause until it completes or you kill it. You can see the "estimate" of how long that current running SQL is going to take in v$session_longops. You can use a script like Tanel's sw.sql
http://blog.tanelpoder.com/2008/01/08/updated-session-wait-script/
to see what the wait interface has to say.

My approach for this would be to determine what the current explain plan is and compare it to one that ran (correctly) in the past and then try to determine why it changed. (bad stats, dropped index, parameter changes, etc).
Cheers.

SQL Tuning Advisor Recommends New Explain Plan

Hi:
I have to believe this has been asked before but didn't see it in a forum search so I'll ask here. I had SQL Tuning Advisor look at a query and it is recommending a new plan for a 50+% improvement (hazah!). The trouble is, I don't want Oracle to re-write the plan to execute the query better, I want to know how I can re-write the query to generate that more optimal plan in the first place because I have similar systems in the field that I would like to also be optimized. What are my options?
Thanks.

Sorry Gaff I know where you are talking about but I don't have your answer, but it may be a good start going over the 19g reference guide for these dictionary views -
SQL> select view_name from dba_views where view_name like 'DBA%ADVISOR%' ;
VIEW_NAME
DBA_ADVISOR_DEFINITIONS
DBA_ADVISOR_COMMANDS
DBA_ADVISOR_OBJECT_TYPES
DBA_ADVISOR_USAGE
DBA_ADVISOR_TASKS
DBA_ADVISOR_TEMPLATES
DBA_ADVISOR_LOG

Enterprise Manager - sql tuning advisor , Access advisor for SQL Tuning

Hi,
NO I mean in oracle 10g you have the enterprise manager which can be used to tune sql statements using the SQL ADvisor and SQL access advisor.
I believe in oracle 10g the process of SQL Tuning is slightly easier using the Enterprise Manager ...so if some one could explain me that process...
Again thanking you in advance

Hi Manoj,
tune sql statements using the SQL ADvisor and SQL access advisor.Do you have the OEM extra cost "performance pack"?
The OEM screens are fairly self-explainatory, but here are some references on the 10 SQL tuning advisors:

Differernce between SQL Tuning Pack and SQL Tuning Advisor, Access Advisor

Hi. all.
I have been using "TKPROF" in order to tune SQL till now.
I am learning 10g, and would like to know the difference
between "1. SQL Tuning Pack" and "2. SQL Tuning Advisor, Access Advisor".
Are they same thing? If not, what are the differences in their "functionality"?
All I know is that SQL Tuning Pack is not free, and SQL Tuning Advisor
is packed with default installation. Right???
Could you give me some html links or your "any advice and experience"?
Thanks in advance. Have a good day.
Best Regards.

Hi,
There are alternatives to the Oracle tuning packs, and remember the SQL advisors are relatuively simple, finding missing indexes and recommending MV's.
A human can do a better job if you use the right techniques.
BTW, you can get a SQLTuning advisor license online for only $3k:
http://www.dba-oracle.com/oracle_news/2005_3_17_dql_tuning_access_advisor_licenses_available_online.htm
SHAMELESS PITCH! - I wrote a book that describes techniques for tuning with scripts, instead of the advisors, if you are interested:
http://www.rampant-books.com/book_2005_1_awr_proactive_tuning.htm
Hope this helps. . . .

Feature option request - SQL Tuning Advisor

Hi,
Love the ability we can run SQL Tuning Advisor so easily in SQL Developer, this is how it should be simple. However we can not specify a few parameter like: time_limit, task_name and description. Would be helpful to have these options, especially increasing the time_limit option!

At least the limit will be increased: 3.0 Tuning Advisor Times Out
Regards,
K.

SQL Tuning Advisor says I have old statistics but they were collected today
