Need Help in sql tuning in EXADATA environment

I am uploadin the sql with its current explain plan, this sql in Prd database is executing in 6-10 mins and we need to improve this sql perf to 1-2 mins as the requirement from business team.
I am giving some backgroud about this sql tuning requirement, this sql is newly developed in and currently is in UAT phase, we don't have much option for tuning code here since the sql is tool generated through COGNOS DataMart tool, options are there to look into from DBA end with plan level or creating indexes on suitible columns to reduce i/o in minimizing the rows traversing by the sql.
Is anybody can help me out here?

SQL tuning suggestions.

Hi
I am not a sql programmer and developers have given me this sql to have a look. I made the following recommendations after going through the sql. Is there anything else that can be added . I did not add about stats because they are representative and up to date.
SELECT /*+ PARALLEL(q1,4) */ *

ORDER BY department_id,

wo_number
My suggestions:
. Try to use UNION ALL instead of UNION. If you can eliminate UNION all together and flatten the query that will be even better.
2. You are using the function in a select statement xxdl_eam_util_pkg.xxdl_eam_get_resource_code(pf.person_id, bd.department_id)This will slow the performance. Try to get rid of this. Function calls in select are expensive.
3. Dont use the parallel hint and optimize. It wont get you consistent results.
4. Use of per_all_people_F is expensive. The UNION again complicates things. per_all_people_f has to be scanned 2x times.
5. Where does the application get the values for department id? Whether user inputs a value or whether it is hard coded . Most likely user will input value and each time it may be different. If that is the case, then you may be hitting bind peeking. There is not much hope for this. Not much can be done. Whatever you do this can happen. Only way is to pin the plan if you can use literals instead of binds. But that is not possible I think.
6. AND DECODE(bd.disable_date,null, sysdate,bd.disable_date) >= sysdate
AND DECODE(br.disable_date,null, sysdate,br.disable_date) >= sysdate
AND DECODE(wo.disable_date,null, sysdate,wo.disable_date) >= sysdate
Those statements, if you can rewrite would be good. If there are indexes on any of those columns, they are more than likely not used.
7. Are the outer joins really required. If not required remove them.
8. There is a 'WITH' clause in 10g . Try to use that for your subqueries or main query where applicable. It will save some I/O.
9. Try to tune without any hints. Remove the first rows as well and see the difference.
I know that the sql is definately bad and can be rewritten but I am not able to exactly write it for them.
Any inputs or thoughts?

Hi,
Any suggestions for reading on Sql tuning
I am looking for a practical book with solutions .
And books showing the Sql internal workings ?Take a look on Amazon some Jonathan Lewis books.
I will also recommend you to take a look on the following blogs:
- http://jonathanlewis.wordpress.com/
- http://www.juliandyke.com/
- http://richardfoote.wordpress.com/
- http://tkyte.blogspot.com/
And also any good interview based good Oracle DBA books ?You can take a look on my blog for some common DBA interview questions.

Oracle 10g SQL Tuning Advisor

I am working as a junior DBA. I tried to tune a query using SQL Tuning Advisor that is with DBMS_SQLTUNE.I have created the tuning task successfully with DBMS_SQLTUNE.create_tuning_task.But when i execute the tuning task with EXEC DBMS_SQLTUNE.execute_tuning_task() i got an error like
SQL> EXEC DBMS_SQLTUNE.execute_tuning_task(task_name => 'rep_three');
BEGIN DBMS_SQLTUNE.execute_tuning_task(task_name => 'rep_three'); END;
ERROR at line 1:
ORA-00081: address range [0x60000000000A7D70, 0x60000000000A7D74) is not
readable
ORA-00600: internal error code, arguments: [kesatmGetSqlStats:optCost], [], [],
ORA-06512: at "SYS.PRVT_ADVISOR", line 1624
ORA-06512: at "SYS.DBMS_ADVISOR", line 186
ORA-06512: at "SYS.DBMS_SQLTUNE", line 1008
ORA-06512: at line 1The oracle version is Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - 64bi. The OS is HP-UX. The version is HP-UX B.11.23 U ia64.
I tried to execute DBMS_SQLTUNE as DWH user.I have granted the advisor,DROP ANY SQL PROFILE,ALTER ANY SQL PROFILE,CREATE ANY SQL PROFILE privileges and DBA roles to the DWH user. The way i ran DBMS_SQLTUNE is, first i logged in as DWH user and i tried to execute the query for getting the SQL_ID for the query. For getting the SQL_ID i selected the SQL_ID column value for the DWH user session from v$session.I kept that query executing and meanwhile i opened another session as DWH user and created the tuning task as follows
DECLARE
l_sql_tune_task_id VARCHAR2(100);
BEGIN
l_sql_tune_task_id := DBMS_SQLTUNE.create_tuning_task (
                          sql_id      => 'b65fj39dkkb9v',
                          scope       => DBMS_SQLTUNE.scope_limited,
                          time_limit => 3600,
                          task_name   => 'rep_three',
                          description => 'Report Tuning');
DBMS_OUTPUT.put_line('l_sql_tune_task_id: ' || l_sql_tune_task_id);
END;
/The creation of tuning task was successful.And i executed the tuning task as follows
EXEC DBMS_SQLTUNE.execute_tuning_task(task_name => 'rep_three');The above mentioned errors came when i executed the tuning task.
I am also adding the query which i have tried to tune

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.

Use of SQL Tuning pack in SAP

We have activated the Oracle 'SQL Tuning pack' however only one function "SQL Tuning Advisor" is activated/visible in ST04
and other functionality is not visible. We have already taken license of 'SQL Tuning pack' .
Other then this we want to use following oracle supported features.
1) Automatic SQL Tuning Advisor
2) Real-time SQL Monitoring
3) Object Reorganization Wizard
As I know we can use "oracle enterprise manager" to use such oracle features, If SAP allow use of OEM in SAP environment.
can someone help here please..?
Thanks,
Kapil Pandey

Hello Kapil,
which other options did you expect to find in ST04? SAP note 1028068 speaks only of the "SQL Tuning Advisor" which will be activated:
As of Enhancement Package 1 for Basis Release 7.00 (that is, Basis Release 7.01), the function "SQL Tuning Advisor" is contained in the DBA Cockpit. This optional function requires the Oracle Tuning Pack to be licensed.
The other features should be used via the OEM, because they are not integrated in the DBACOCKPIT transaction:
- Automatic SQL Tuning Advisor
- Real-time SQL Monitoring (with OEM you even get a really useful visualization)
- Object Reorganization Wizard -> better use brspace because it is supported by SAP

Mark

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. . . .

Any tool or shortcut to get SQL tuning suggestion???????

Hi I have to tune an application and need to go throught alot many SQL their PLAN and ti tune them.
I want to know ether is there any tool online or may be from oracle to get the tuning suggestions straighytway.my oracle version is 9206
Can i use 10g SQL tuning advisor with 9i database????
Thanks
Gagan

Hi Gagan,
Can i use 10g SQL tuning advisor with 9i databaseNo, but you can do the same thing manually, and often do a better job:
Tune SQL with optimizer parms:
http://www.dba-oracle.com/t_sql_optimizer_parameters.htm
Find missing indexes:
1 - Search for unnecessary large-table, full-table scans
2 - Compare consistent gets to rows returned

OEM - No ad-hoc SQL tuning?

Am I correct that there is no way to say to Oracle Enterprise Manager's SQL Tuning Advisor, "here is some SQL - please analyze and tune it". The only way to get it to tune something is to find it running and then say "please run the SQL tuning advisor on it".
In other words, no way to tune a query without running it first...?
I've been looking for a way to do this in OEM and can't find it.
Thanks!

Last I checked, explain plans tell you what will happen, not how you might change things to improve itIf/when an experienced & KNOWLEDGEABLE person see a BAD plan, they may be able to reformulate the SQL to produce a better plan.
which is what the SQL Tuning Advisor does.Those who live by the GUI, die by the GUI.
Some/many folks would be incapable of doing anything with or to Oracle RDBMS if OEM did not exist or was broken.Did I ask for opinions on the One True Way to be a DBA, or for a comparison of SQL*Plus vs. OEM, or a survey of the competence level of typical DBAs?
No.
I asked a simple, technical question about OEM.

How to check SQL Tuning Advisor task is exist or not

How to check SQL Tuning Advisor task is exist or not using DBMS_SQLTUNE,
I want to remove SQL Tuning Advisor task only if it is exist using DBMS_SQLTUNE.DROP_TUNING_TASK function

Two approaches.
1. Look up in DBA/USER_ADVISOR_TASKS, if it exists, drop it.
2. Drop it, ignore the exception
3. Drop it, catch the exception (specific exception if you want to rightly avoid such constructs as when others then null) obviously within an inner block is you want to catch and then move on to do other work.
SQL> declare
2   e_no_such_task exception;
3   pragma exception_init(e_no_such_task,-13605);
4   procedure forgetaboutit
5   as
6   begin
7      null;
8   end;
9 begin
10     begin
11       dbms_sqltune.drop_tuning_task('NON_EXISTENT_TASK');
12     exception
13          when e_no_such_task then
14               forgetaboutit;
15     end;
16     -- do something else
17     null;
18 end;
19 /
PL/SQL procedure successfully completed.
SQL> P.S. Ignore procedure forgetaboutit - just amusing myself...

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?

SQL Tuning for Exadata

Hi,
I would like to know any SQL tuning methods specific to Oracle exadata so that they could improve the performance of the database?
I am aware that oracle exadata runs with Oracle 11g, but i would like to know wheather there is any tuning scope w.r.t to SQL's on exadata?
regards
sunil

Well there are some things that are very different about Exadata. All the standard Oracle SQL tuning you have learned already should not be forgotten as Exadata is running standard 11g database code, but there are many optimizations that have been added that you should be aware of. At a high level, if you are doing OLTP type work you should be trying to make sure that you take advantage of Exadata Smart Flash Cache which will significantly speed up your small I/O's. But long running queries are where the big benefits show up. The high level tuning approach for them is as follows:
1. Check to see if you are getting Smart Scans.
2. If you aren't, fix what ever is preventing them from being used.
We've been involved in somewhere between 25-30 DB Machine installations now and in many cases, a little bit of effort changes performance dramatically. If you are only getting 2 to 3X improvement over your previous platform on these long running queries you are probably not getting the full benefit of the Exadata optimizations. So the first step is learning how to determine if you are getting Smart Scans or not and on what portions of the statement. Wait events, session statistics, V$SQL, SQL Monitoring are all viable tools that can show you that information.

Permissions needed for Applying SQL Tuning Sets/SQL Plans 11g?

What permission are needed for a user to apply/activate sql tuning sets (sql plans) in 11g? The user can capture and move the the sql tuning sets from a 10g database to an 11g database but is getting "ORA-01031: insufficient privileges" when trying to activate/apply the sqlplans in 11g.
The user has:
ADMINISTER SQL MANAGEMENT OBJECT and ADMINISTER SQL TUNING SET and EXECUTE on SYS.DBMS_SPM
The user is an administrator for our Data Warehouse team but they do not have sysdba priviliges.
Do you also know of a good white paper that covers the step by step instructions and permissions needed for aquiring and applying/activating sqlplans?
If more information is needed in order to respond please advise.
Thank you
