Tuning advisor Essbase / statistics Viewer?
HelloIs there a tool that can help me fine tune my calculation scripts / business rules? I would like to know for example, how many blocks is affected with a few patches, or accurate members where a fix calculation will have effect if I used a function such as @Ancestors or @Children within a patch.
It would be to do some tests and check the time they take calculation.
Thank you
I would like to know for example how many blocks is affected with a couple of fixes
^ ^ ^ SET MSG SUMMARY or SET of DETAILS of MSG and the application log will tell you that. It's kind of a pain to work with, but that's all what he.
Kind regards

Can someone show me that some light on what changes made Advisor to select to reach that way, or how can I watch this that select uses?
Any help will be appreciate
Thank youThe Adviser does not create a new SQL statement - what it has done is create a SQL profile - to accept SQL profile for the task of tuning above:
execute dbms_sqltune.accept_sql_profile(task_name => 'SQL_TUNING_1266335308111', replace => TRUE);as mentioned in the above report...
A sql profile applys tips for change (correct) the cost of certain operations - and, to change the execution path chosen by the optiimizer.

Tuning Advisor - recommendations
Dear Experts,
11.2.0.3 RDBMS - I ran Setup SQL for a statement and see the three recommendations:
-Collect statistics for a table
-Implement the SQL - 99% of shows benefits profile
-Creating an Index - shows about 78% benefit.
Tuning advisor recommends that a recce to implement. We should I be implemented? Also, with the SQL profile I see 'force match' option, what it means? Appreciate your help...
Thank youHello
Profile SQL is generally less preferable because
(1) fixed single query
(2) it arranges without understanding the nature of the underlying problem, i.e. There is always risk of returning question in one way or anotherOn the option 'force game' - it just means that the profile will apply not only to the sql_id you specify, but also all other sql_id which the SQL text differs only in the values of literals. For example if you create a SQL profile for
select col1 from tab1 where col2 = 'A'then by default will not affect the plan of
select col1 from tab1 where col2 = 'B'but with strength match option, the profile would apply to these two statements.
About creating index - you need to evaluate the benefits for this and other queries on the cost (slower DML, increased consumption of disk space). How to set up SQL cannot do this for you.
Best regards

SQL tuning advisor recommnds to create the function SYS_OP_C2C function index
I have a large table and an index on it. I use a tool to fill data, this simple tool submits the sql for Oracle DB and it does NOT index to use for requests. When I run the sql tuning advisor, he recommends to create additional indexes and use the SYS_OP_C2C function, which I don't want.
When I run the query through sql plus picks it up in the index.
Someone of you came, why its recommend that additional nonsense?
create index abc.xxxx on this_table (SYS_OP_C2C ("this_column"));
Thank youThe internal Oracle SYS_OP_C2C function perform the conversion of a set of characters to another set of characters - C (haracterSet) 2 c (haracterSet). There are situations where you will see this conversion without explicit, as in this case command that should be a sign that the data types are not the same and the implicit conversion takes place and this could also be a problem from the point of view performance because it can disable the use of the index.
Make sure you the characterset and nls set of all of the database and the tool are the same.
Make sure that the data type of the column in the index is the same as the database.
Confirm the ETL vendor for your database support and fixes, etc..Optimizer will only advise to use this function when the data type or the character set does not match.
Thank you

License required for "Automatic SQL Tuning Advisor"?
I noticed a lot of databases in my company show using a component called "Automatic SQL Tuning Advisor" or "Automatic maintenance - Setup SQL" in DBA_FEATURE_USAGE_STATISTICS.
Do we know if this component requires a License Pack Tuning or it could be one of the internal out-of-box/system uses that do not require a license?
Thank you!

Hi all

I ran sql tuning advisor manually by using procedure
sample procedure:

sql_id = > "ct4u2889m1458"

Then I performed the task of tuning created using the procedure

Once again received message as PL/SQL procedure successfully completed.
But when I query using SELECT * FROM dba_advisor_log WHERE task_name = "_tuning";
I got this output in the respective, INTERRUPTED, ORA-13639 column: the current operation was interrupted because it has expired.
Any idea or suggestion, why im getting this error, should I get the FINISHED status. I even tried to increase the values of time_limit, but still no go...

I increased the parameter time_limit to half an hour. and his filled and got the sql tuning report...

It seems you found somone activated of sets and the setting of advisers. as others have said, theyre part of the D & T and theyre always there but only, you become eligible for a permit after that you use.

I did not open any excel, to do not understand what this errir for and how to solve it.
Please help the Essbase gurus.
You probably have another Office application running - remember, Office is not just Excel and Smart View works with those of other applications also - and / or open invisibly. If you open the Task Manager and look at the process, you can see an instance of EXCEL. EXE (for example) even if Excel is not visible as an application on your desktop.

access SQL vs tuning question Advisor
I am trying to understand a question which is:
Which of the following identifies and creates an index to reduce the time of the DB for a given SQL statement?
(a) SQL Tuning Advisor
(b) SQL Access Advisor
I think the right answer is a) tuning advisor, because it is for a given SQL statement and it can also be configured to automatically create an index when it runs over the extensible standard maintenance task. However, the marked answer is b) Access Advisor. That which is correct and why?
Thank you!Waldrfm,
I guess this question of OCP is also asking if STA or SAA make recommendations in terms of DB Time (%) or the cost of the workload (%).
When you look at the details of STA recommendation, it is show recommendations by times of DB (which includes the DB service time + queue DB time) *, in particular for each SQL statement.
However, when you look at the details of recommendation of SAA, is show the recommendations by improving Total cost (which is the cost of CBO, SUM (IO + CPU)). * instead of DB self time
SQL statement.
For example,.
When you tune in 10 identified SQL statements using the STA, it tunes indivdual SQL statement acting time of each SQL DB.
SAA tunes instructions SQL 10 identified as a workload making recommendations based on improving Total cost of the entire workload.

Need to learn the code of PL/SQL tuning
Hi all
I already asked this question earlier, but the link provided was too difficult to understand, I really grateful if someone suggest me the good and simple link or presentation for mentioned topic question.
In addition, I just want to learn some basic for this. Appreciate your response. Thank you

I already asked this question earlier, but the link provided was too difficult to understand, I really grateful if someone suggest me the good and simple link or presentation for mentioned topic question.
Why PL/SQL tuning?
The best advice re PL/SQL is to AVOID at all costs. Whenever possible, use SQL.
It is usually the SQL to be tuned so that sql is autonomous or in code.
As the major part of PL/SQL uses SQL to get the job done, you will be not successful tuning PL/SQL, unless you set the SQL contained in it.
Start with the Oracle documentation:
http://docs.Oracle.com/CD/B28359_01/server.111/b28274/sql_overview.htm
This chapter deals with the objectives for the development, explains how to identify the high resource SQL statements, which must be collected, offers suggestions of setting and explains how to create SQL test scenarios to solve problems in SQL.
This chapter contains the following sections:
Then, learn how to use and interpret what the Wizard Setup of Sql from Oracle can make and provide:
Update Auto SQL - 11 g Release 2 (11.2)
17 automatic SQL Tuning
This chapter examines the SQL Auto setting of the Oracle database features. Automatic tuning of SQL automates the manual process, which is complex, time consuming and repetitive.
This chapter contains the following sections:
A lot of questions of PL/SQL, you encounter will be due to one of these things:
1 poorly written SQL (see SQL tuning above)
2. use of slow-by-slow (line by line) treatment in a loop
3. poor use of collections and in bulk of treatment
4. use of the dynamic sql
All those who will take you to the SQL itself. The SQL is not set correctly if it is not possible for the PL/SQL to be tuned.
