Oracle 10g sql tuning

I am on Oracle 10.2.0.3 on Windows 2003.
I have a third party package whose code cannot be modified. There are several queries written using NOT clauses, as a result Oracle does full table scan and hash joins.
select * from svp_view_s where NOT a_webc_url like '%dm_sig_source%.pdf' and
r_object_id in (Select parent_id from svp_view_l where child_id='098c4230800d7dd7' and NOT
a_webc_url like '%dm_sig_source%.pdf');
Is there a way to force it in a generic fashion to use indexes instead of explicitly adding hints to use specific indexes. Oracle many times ignores the hints. Also I do not have access to code, so somehow has to figure out how to use stored outlines.
There are many queries. I was looking at some generic solution.

Look into whether you can use the DBMS_ADVANCED_REWRITE built-in package.

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:

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

How to use Oracle 10G SQL features in OWB?

We are using OWB repository 10.2.0.1.0 and OWB client 10.2.0.1.31. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
Oracle 10G SQL offers
1) Inserting Into a Table with Error Logging
2) conditional_insert_clause, Specify the conditional_insert_clause to perform a conditional multitable insert.
Did anyone use above features in OWB10G mapping?
How do we use them?
Thanks in advance.
RI

Hi,
Just a thought on the multi-table insert. OWB generates multitable insert when one source is mapped to multiple targets only on the condition that after the splitter there should not be any OWB operator that can change the cardinality of the row-set coming out of the splitter (like joiners, filters, aggregators etc.)..
Regarding the link, I was wondering where I could find a decent documentation of the shadow table and the DML Error Logging through OWB .. Thanks for the link.
OWB error messages are basically Oracle Error Messages when you consider the code that gets deployed. Other than that VLD errors are sometimes mysterious and hard to debug.. Hope someone can give us more details on how to handle such VLD errors :)

Oracle 10g SQL Profiler Equivalent?

As per the subject, I can monitor sessions via the web gui, but I need to see actual SQL statements that are hitting the 10g server. Is there an Oracle 10g SQL Profiler equivalent?

XE?
You might want to hunker down with some of the docco available at http://www.oracle.com/pls/db102/portal.portal_db?selected=1
In particular, you could look at the 'Reference' manual (not SQL Reference, or any other ... Reference) and browse through the DBA_ and V$ views listed. The Concepts and Administration manuals are interesting as well.
The specific views of interest include, but are not limited to, V$SQLAREA and V$SQLTEXT

Your problem is most likely in decode - the return type in your expression will be character based on first search value ('null'), so it will be implicitly converted to character and then again implicitly converted to date by loading into date column. At some of this conversions you probably are loosing your time part. You can try instead use cast:
SQL> desc t

LASTUPDATEDON                                      DATE

Oracle 10g performance tuning tools

hi,
can anyone please suggest me any oracle database tuning tool to use for improving the performance of the database?(oracle 10g)

Hi,
Do you want a tuning tool that does not require the user to have in-depth Oracle knowledge? If so, try here:
http://images.google.com/images?&q=ouija+board&um=1&ie=UTF-8&sa=N&tab=wi
Seriously, I like to use AWR and STATSPACK reports, and there are some freeware tools to help analyze them, one that I sponsor:
http://www.statspackanalyzer.com
For online tools, Oracle SQL Developer is a great way to get started, as-is the Oracle performance pack:
http://www.oracle.com/technology/products/database/sql_developer/index.html
For third-party tuning tools, look at Confio, quite good:

Hope this helps. . .

How to login in Oracle 10g SQL Plus

I just installed Oracle 10g. I tried to login to SQL Plus by using scott and tiger to be user name and password, but it did not work. What can I do about it?
Please help and thanks in advance!!!

You have to configure a Net service name, and connect as
sqlplus scott/tiger@<service_name>
You can use the Net Configuration Assistant to do that. This is in the Oracle menu on Windows systems. On Unix/Linux you can use the netca utility.
If you are working locally (on the server), you can also set the ORACLE_SID environment variable :
Windows : set ORACLE_SID=<your_sid>
Unix/Linux : ORACLE_SID=<your_sid>; export ORACLE_SID
then connect as
sqlplus scott/tiger

Oracle 10G Performance Tuning

A colleague of mine supplied me with a tuning script to help in my performance analysis of a 10.2.0.1 Oracle database. The script is called:
responsetimebreakdown.sql
Apparently this was designed for 8i as it cannot find the sys.x_$ksles (session events) view or table in my Oracle 10.2.0.1 database. I receive:
ORA-00942: table or view does not exist
Any one know the equivalent of this object in 10G or has access to this script designed for use against a 10.2.0.1 Oracle database?
Thanks.

I don't know what your script does, but here's the table you're looking for. 
SQL> select name from v$fixed_table where name like '%KSLES%';

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

Hope this helps. . . .
