SQL tuning advisor in 11G.

Hi,
our dev guys given poor performance query to me to tune.
Can any one able to provide me steps to get recommendation from SQL tuning advisor by creating tuning task for a manually specified statement.
Version : 11.1.0.6.0
OS : SunOS 5.10
Thanks in advance!

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"
saying like
ERROR at line 8:
ORA-06550: line 8, column 22:
PLS-00103: Encountered the symbol "MM" when expecting one of the following:
* & = - + ; < / > at in is mod remainder not rem
<an exponent (**)> <> or != or ~= >= <= <> and or like like2
like4 likec between || member submultiset
The symbol "*" was substituted for "MM" to continue.
Then i have replaced with
"to_char(max(r.ts), :bnd) viewrequest_lastdate". After this task is created & executed. Right now, im getting below error.. plz advice.

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.

[OCP exam] doubt about Automatic SQL Tuning Advisor

Hi,
Sorry for my poor english.
I am currently preparing for the OCP 11g exam.
For that, I have bought some training tools to help me prepare the exam.
But, in the chapter related to the SQL tuning advisor, some explanation really confuse me .
Extract :
<<
the SQL automatic tuning job runs every night during the maintenance window.
By default, the job makes SQL profile recommendations, tests them, and automatically implements them if they provide better performance improvement)
>>
I was persuaded it was the opposite.
I check several databases/documentation, and it's seems to be always the opposite.
By default,new sql profile are tested but not implemented automatically (you have to set a parameter ACCEPT_SQL_PROFILES TO TRUE to activate this option)
But the exam is validated on oracle 11.2.0.1, and I only have 11.2.0.2/11.2.0.3 db available.
So may be oracle changed the value of the default parameter in the new releases.
Can someone confirm if I am right or not ?

I would rather accept what is in the documentation:
"If a SQL profile is recommended, the database tests the new profile by executing the SQL statement both with and without the profile. If the performance improvement improves at least threefold, then the database accepts the SQL profile, but only if the ACCEPT_SQL_PROFILES task parameter is set to TRUE. Otherwise, the automatic SQL tuning reports merely report the recommendation to create a SQL profile." Automatic SQL Tuning
"If automatic implementation of SQL profiles is enabled (the default is disabled), then the database implements any SQL profiles that promise a great performance benefit. The implementation occurs at tuning time so that the database can immediately benefit from the new plan. You can enable or disable automatic implementation by using the SET_AUTO_TUNING_TASK_PARAMETER API to set the ACCEPT_SQL_PROFILES parameter." DBMS_AUTO_SQLTUNE

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

Additional licenses reuired for using Sql Tuning Advisor In SQL Developer 4.0.3

The Oracle Tuning Pack is DATABASE functionality - it is part of the database. Sql Developer just uses it.
Yes - to use ANY of the features of the tuning pack requires an extra cost license.
http://docs.oracle.com/cd/B28359_01/license.111/b28287/options.htm#CIHFIHFG
Oracle Tuning Pack
The Oracle Tuning Pack provides database administrators with expert performance management for the Oracle environment, including SQL tuning and storage optimizations. The Oracle Diagnostic Pack is a prerequisite product to the Oracle Tuning Pack. Therefore, to use the Tuning Pack, you must also have a Diagnostic Pack.
The Tuning Pack includes the following features:
SQL Access Advisor
SQL Tuning Advisor
Automatic SQL Tuning
SQL Tuning Sets
SQL Monitoring
Reorganize objects
In order to use the features listed above, you must purchase licenses for the Tuning Pack, with one exception: SQL Tuning Sets can be used if you have licensed either the Tuning Pack or Oracle Real Application Testing. A new initialization parameter, CONTROL_MANAGEMENT_PACK_ACCESS, is introduced to control access to the Diagnostic Pack and Tuning Pack in the database server. This parameter can be set to one of three values:
DIAGNOSTIC+TUNING: Diagnostic Pack and Tuning Pack functionally is enabled in the database server.
DIAGNOSTIC: Only Diagnostic Pack functionality is enabled in the server.
NONE: Diagnostic Pack and Tuning pack functionally is disabled in the database server.
The Tuning Pack functionality can be accessed by the Enterprise Manager links as well as through the database server command-line APIs. The use of either interface requires licensing of the Tuning Pack

Recommendation (estimated benefit: 71.48%)
- Consider running the Access Advisor to improve the physical schema design
or creating the recommended index.
Error: Cannot fetch actions for recommendation: INDEX
Error: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
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.

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

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 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. . . .
