SQL TRACE/TKPROF VS SQL ACCESS ADVISOR

Hi All,
Can anyone please tell me what's the exact difference between SQL TRACE/TKPROF and SQL ACCESS ADVISOR in Oracle 10g.(By showing some examples)
And also why should I go for SQL ACCESS ADVISOR ?? (Since I have used the former all these days) :)
Why can't I still use SQL TRACE/TKPROF.
Please if anyone can pour light on this. Thanks in Advance.
Regards,
Marlon.

SQL Access advisor

We are on SQL Developer 3.2.09. We have a SQL tuning advisor Icon in this version. I am wondering if we can access SQL Access advisor for a specific query - I need advise on Materialized View creation. We can invoke DBMS_ADVISOR package for a set of SQL(s) but do we have this integration buit in SQL Developer. We are using Oracle 10gR2 and 11gR2.
Thanks

Pl post details of OS and database versions, along with what you are specifically trying to do.

Differece b/w SQL Tunning & SQL Access advisor

What the difference b/w these 2 , i know SQL Access advisor suggest for index or materialize view for fast query....what SQL tunning do?

Mithu,
Please stop lying!!!
You are not new in this field. You have been asking RTFM questions for almost three years!!! When I had three years experience, I didn't need to ask the questions you think you need to ask. I LOOKED THEM UP IN THE DOCUMENTATION!!
I will continue to expose your attitude as abysmal.
You are in flagrant violation of the Etiquette in this forum.
You are a parasite. You don't want to do anything to resolve your own questions.
You are a disgrace to the DBA profession.
In fact, because of this I may want to have your account removed.

Do i implement SQL Access Advisor Recommendations

Hi,
I am using oracle 10.2.0 and i run SQL Access Advisor which gives me recommendations. But i can't figure out how many recommendations or all or some of them on any criteria i should implement and will they improve database performance.
Thanks
Umesh

The Recommendation text would have the information of the SQL for which you have ran the Advisor and gives you the Explain and cost involved. Also,it would tell you the percentage of benefit by implementing the Recommendations.it gives you an adjusted PLan with cost and how you implement the same.
Follow the process in your Test environment and to see if you get the same recommendations. if so, implement and see whether it really improved the performance or not.

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:

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

Hi,
We have Oracle Database 11g Enterprise Edition Release 11.2.0.3.0. Do we need to purchase an additional oracle license for using SQL Tuning Advisor Option in SQL Developer 4.0.3

We have Oracle Database 11g Enterprise Edition Release 11.2.0.3.0. Do we need to purchase an additional oracle license for using SQL Tuning Advisor Option 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

Access Advisor Job fails every time?

hi
i made a tuning set and tried to get some recomondations for tuning by starting a sql access advisor job.
After i submited the job i see unter the "oracle sheduled" my failed job. as error message i get the following information if i click the button for showing the job defintion:
"ORA-13605: The specified task or object string does not exist for the current user."
and indeed the user name is shown empty. how can i set a user for an access advisor job? or why doesn't that happen automatically?
can anyone help me?

This turned out to work for me, too! It was nothing to do with network switch configuration, per se-- or at least I didn't have to change anything on my switch to fix it. Instead I tried fusiongroup's method of getting into the command-line before the WinPE
boot hit the "Preparing network connections" step, and I repeatedly ipconfig /renewed until suddenly the TS reached the next step of the sequence instead of failing out.
I also made this an "Available" sequence instead of a "Required" sequence, which I think buys you a little time in terms of offering a GUI in WinPE for the sequence, instead of just trying to run it.
One last thing: I was running this on a Workgroup machine that is not joined to our domain; I had followed another tutorial to get the client installed on it even though it's outside the domain. Prior to trying the command-line fix fusiongroup gave, I also
went into Assets and Compliance in Configuration Manager and right-clicked the machine in the list of devices, and found that I had to "Approve" it for management by SCCM. Don't know if that helped as well.

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:

Hope this helps. . . .

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: 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?

LC10 - Monitoring: I get a message that SQL Access Not Possible

In our SCM 2007 system, when going to transaction LC10 -> Monitoring, I get a message in the top left box that says SQL Access Not Possible. Also, when I go to LCA03, I get a short dump with: Exception condition "LC_CONNECT_FAILED" raised.
This started happening after I changed the password for users: control and lcuser within the livecache database. I updated these passwords withing SCM -> LC10 -> integration and restarted the SCM system, but I still get this failure. I can run commands against the livecache database directly with dbmcli using the same username / password I put into LC10 and I don't get any errors.
This error shows up in the work process trace:
C *** ERROR => Connect to database failed, rc = -4008 (POS(1) Unknown user name/password combination)
If anyone has experienced this before, I appreciate any input. Thank you.

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 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
