Sql tuning advisor question

Hi,
Version 10203
Please look at the results of the created tuning task.
The task was created , but did not return any results.
Is that mean oracle cant advice , or maybe i made some mistakes ?
SQL> declare
2 l_sql_id v$session.prev_sql_id%type;
3 l_tuning_task varchar2(30);
4 begin
5 l_sql_id := 'bf8wy6bhr6nak';
6 l_tuning_task := dbms_sqltune.create_tuning_task(sql_id => l_sql_id);
7 dbms_sqltune.execute_tuning_task(l_tuning_task);
8 dbms_output.put_line(l_tuning_task);
9 end;

dbms_sqltune.report_tuning_task returns a CLOB.
Try setting LONG to 1000000 in your session:

You may also wish to set longchunksize <big number>Regards,

Sql tuning advisor question on bind values

Hi guys,
I used the sql tuning wizard in Oracle 11g to get recommendation on how to improve performance on a long running query. Here is the recommendation I received:
At least one important bind value was missing for this sql statement. The
accuracy of the advisor's analysis may depend on all important bind values
being supplied.
Could someone please help me understand what it means? For example, what is a bind value, why was it missing, and why are they important?
Thanks!

I've seen this message maybe once before but I've never investigated it - I don't tend to run the SQL tuning advisor.
The best thing you could do is investigate the circumstances yourself, maybe trace the tuning advisor and see where it's getting its data from internally.
As mentioned, where it gets its data from depends on how you populate the tuning advisor - from cursor cache, awr, etc.
If it's from AWR as you mentioned, have a look at DBA_HIST_SQLSTAT.BIND_DATA for example? Or maybe DBA_HIST_SQLBIND? Etc.
You can check what the advisor probably pulls out of AWR using something like this:
select *
from   table(dbms_Sqltune.select_workload_repository
             (begin_snap   => 6441,
              end_snap     => 6443,
              basic_filter => 'sql_id = ''gr5tqfnz07sxk'''));If the bind_list is empty then you know what it's complaining about.
I just tried it with an example sql it that I can see has bind data in DBA_HIST_SQLSTAT and DBA_HIST_SQLBIND and the BIND_LIST in the SQLSET returned by the SQL set above is null so that raises some questions ( I might be doing something wrong but as mentioned, it's not really something I tend to use).
The BIND_DATA raw is populated for me (although the bind_list collection isn't hence why original comment above).
If you know a representative set of binds, you can kick off your own tuning task manually and supply your own set of binds - see DBMS_SQLTUNE.CREATE_TUNING_TASK.
You can also extract and inspect the RAW BIND_DATA into a set of binds using DBMS_SQLTUNE.EXTRACT_BINDS.
e.g. to inspect:
select x.*
from   v$sql s
,      table(dbms_sqltune.extract_binds(s.bind_data)) x
where sql_id = '<sql_id>';Edited by: Dom Brooks on May 17, 2012 5:59 PM

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.

Hi Mark,
Thanks for your interest, yes, the index is being used . Here is the evidence that you were asking about.
It has existed for many weeks, now as the info below will show.

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

Ados

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.

Any ideas why I am getting ORA-06502 error?

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.

Change automatic SQL Tuning Advisor time

Hi All,
can anyone help me in changing "automatic SQL Tuning Advisor" job timingsm because currently it is scheduled during peak hours , i want to change it to evening 6 pm daily.Because during peak hours it is taking more cpu and taking one hour.
Wed May 08 08:00:10 2013
Begin automatic SQL Tuning Advisor run for special tuning task "SYS_AUTO_SQL_TUNING_TASK"
Wed May 08 08:05:47 2013
thanks
Mapps

Hello,
Here's what you can do,
Create a new window to the time you want it to run:
EXEC dbms_scheduler.create_window(window_name => 'YOUR_WINDOW_NAME',
duration => numtodsinterval(1, 'hour'),
resource_plan => 'DEFAULT_MAINTENANCE_PLAN',
repeat_interval => 'FREQ=DAILY;BYHOUR=18;BYMINUTE=0;BYSECOND=0');>
The above window would be in effect from 6 pm to 7 pm.
Then, disable automatic sql_tuning and then re-enable it to run on the window you just created:
EXEC DBMS_AUTO_TASK_ADMIN.DISABLE(client_name => 'sql tuning advisor',
operation => NULL,
window_name => NULL);>
and now set it to run to your window:
EXEC DBMS_AUTO_TASK_ADMIN.ENABLE(client_name => 'sql tuning advisor',
operation => NULL,
window_name => 'YOUR_WINDOW_NAME');

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
...Best regards.

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
regds
Manoj Gokhale

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. . . .
