SQL Tuning sets and SQL Tuning Advisor.
Hello
We run oracle11g r2 where under win server 2008 R2.
How can I find out when Tuning SQL and SQL Tuning games advisors are enabled in my database.
Is Oracle11g has default setting YES for this tuning packs
Thank you
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. This will tell you the first time they have been used if at all, the key here for you field be FIRST_USAGE_DATE that must be completed only if detected_usages > 0
fixed lines 180
Col name format a30
SELECT name, version, detected_usages, FIRST_USAGE_DATE, last_usage_date
of DBA_FEATURE_USAGE_STATISTICS
where upper (NAME) like '% % TUNING '.

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!

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.

You must mention the time_limit parameter in the above procedure: dbms_sqltune.create_tuning_task - when the task was created. There is an example here: ORACLE-BASE - database Oracle 10 g automatic SQL Tuning and Automatic SQL Tuning as well.

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

Hi all
Oracle 11.2.0.3
IBM Aix box
I ran sql tuning advisor manually by using procedure
sample procedure:
() DBMS_SQLTUNE.create_tuning_task
begin_snap = > 139758,
end_snap = > 139762,
sql_id = > "ct4u2889m1458"
scope = > DBMS_SQLTUNE.scope_comprehensive,
time_limit = > 60,
Task_Name = > 'Settings')
I got the message from PL/SQL procedure successfully completed.
Then I performed the task of tuning created using the procedure
EXEC DBMS_SQLTUNE.execute_tuning_task (TaskName = > 'settings');
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...
Kind regards
I increased the parameter time_limit to half an hour. and his filled and got the sql tuning report...
Thank you

JDBC-fetch data - set and very big (table 35)
Hello
I'm trying to get a very large data set and the desired behaviour is that it continues to function without exception of lack of memory (that is, it's good that it takes days but don't blow up on out-of-memory exception) *.
The task runs on a 64-bit with 16 processors computer.
For testing purposes, I used a table 35 GB in size (of course this would not be our typical fetch but just to emphasize JDBC)
+??? Java exception occurred: +.
+ means: Java heap space.

In the light of this problem, I added jdbc-fetch-size = 999999999 on my JDBC connection string.
' com.microsoft.sqlserver.jdbc.SQLServerDriver ',' jdbc:sqlserver://SomeDatabaseServer:1433; databaseName = SomeDatabase; integratedSecurity = true; JDBC-fetch-size = 999999999; »

Published by: devvvy may 6, 2011 01:10There is one thing to go too far. You won't push ever that a lot of data in memory at a time, which seems to happen due to the vector between the two. The amount of objects that must be created would be already staggering.
Best is to use a result set and browse results instead, treat the rows one at a time, or maybe a batch. Who will use only as much memory as necessary to keep a line / a lot of lines in memory unless the driver not just preloading of magic.

What is blue screen and what to do and how to fix this with out taking back to factory setting and reinstalling Vista
When a BSOD (Blue Screen of Death) the system failure occurs, for most users, there not enough time to fully record what he says. the exact text is important for anyone trying to diagnose what is wrong. You can save time when the error occurs then by following the procedure described below.
If you already did it disable the auto reboot system error. This should help by allowing the time to write the code to Stop error and related information correctly. Select Start, do a right-click on computer select Properties, advanced, system settings startup and recovery, system failure and uncheck the box before automatically restarting. Re-do not enable automatic restart in the event of system failure after obtaining this information, this setting is the best left to not allow an automatic restart.
If the failure occurs during the initialization of the computer, you need to try a different approach. You can access the Advanced Options Menu of Windows on multiple computers by constantly pressing the F8 (key) key when starting and selecting the option - disable automatic restart in case of system error. This method is not always easy to use because it may be difficult to press the F8 key at the right time. Try again if it doesn't work the first time. On some computers, a different key must be used.
