List Sql Tuning Sets

I am hoping for a quick easy answer on this. grin
We have been generating a number of Sql Tuning Sets via Grid Control and now we want to export them. Of course, they all have these awful, non-descriptive names. How do we list them? I was unable to find any help in the "automatic SQL tuning" guide (Chapter 12) of the Performance Guide, and browsing the DBA_* and other fixed views has not revealed anything, yet.

Does this help?

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

Loading SQL Tuning Sets

On a 10.2.0.4 database, is it possible to load SQL Tuning sets with SQL from a text file? I can't find anything in the documentation mentioning this but I could have simply missed it and this facility would be very useful to us.
Our reporting tool is MicroStrategy which operates by building lots of temporary tables: extracting the SQL via Top Activity EM page will put the CTAS statement into the tuning set which (I believe) is ignored by SQL Access Advisor - extracting the sql to a text file, editting to remove the "create table as" and executing in order to load the tuning set is very long winded for a set of queries - at least being able to load the tuning set directly with a set of SQL select statements directly from a text file would help significantly.
Many thanks for any advice
Pete

I did not see a direct way to create the STS from a text file. From the docs:
"The standard sources for populating an STS are the workload repository, another STS, or the cursor cache"
http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/sql_tune.htm#i34915
But you could try a couple of things:
1) create one tuning task per statement, using DBMS_SQLTUNE.CREATE_TUNING_TASK, which can use plain text as input: http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/sql_tune.htm#CHDJDHGE
2) create the STS with queries from cursor cache: http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sqltun.htm#i1010615
Both approaches needs some PL/SQL programming, but it can be useful if you can identify your SQL statements some way.
Regards.

According to the documentation:
SEED_COL_USAGE ProcedureThis procedure iterates over the SQL statements in the specified SQL tuning set, compiles them and seeds column usage information for the columns that appear in these statements.
Syntax
DBMS_STATS.SEED_COL_USAGE (
sqlset_name IN VARCHAR2,
owner_name IN VARCHAR2,
time_limit IN POSITIVE DEFAULT NULL);>
It looks like you need to provide a SQLSET_NAME and OWNER_NAME to use this procedure correctly, to which you've provided NULLs. I don't see any exceptions in the documentation that indicate special processing when NULLs are provided.

Modify sql tuning set

Hi Experts
I have created a sql tuning set with all sqls from cursor cache referring table1. Now I have transported this sqlset to nonprod environment, now what I want to do is make table1 partitioned and test the impact. Instead of altering table1 I want create copy of table1 as partitioned table2. Is there a way I cancl change the sqls in my sqlset to refer to table2 in place of table1. So I basically want to update the sqls with table2 instead of table1. Is this possible and if yes how? If no any other way of doing it, sqlset has ~200 sqls

Why ever not!
1. You create a new user with the appropriate privileges
2. Logon as the new user and create private synonmys (if public ones do not exist) for the objects you need to use
3. Either import a sql set or create a sqlset.
4. Create and execute an analysis task - this will be your baseline
5. Build test1 table as a partitioned table in the new schema - this will override the public synonym
6. Execute an analysis task - this will be your post change run
7. Compare results.

SQL tuning set for specific SQLID

Hi,
Is it possible to create SQL tuning set for specific SQLID's?
Advance thanks!

do you have any code or some package to do this?As long as those statements are in AWR or the cursor cache then you can use
DBMS_SQLTUNE.SELECT_CURSOR_CACHE or
DBMS_SQLTUNE.SELECT_WORKLOAD_REPOSITORY For example something like this:
begin
DBMS_SQLTUNE.CREATE_SQLSET(
    sqlset_name => 'my_tuning_set',
    description => 'my tuning set');
end;
DECLARE
baseline_cursor DBMS_SQLTUNE.SQLSET_CURSOR;
BEGIN
OPEN baseline_cursor FOR
      SELECT VALUE(p)
      FROM   TABLE(DBMS_SQLTUNE.SELECT_CURSOR_CACHE
             (basic_filter      => 'sql_id in (''1'',''2'',''3'')',
              attribute_list    => 'ALL'
              )) p;
    DBMS_SQLTUNE.LOAD_SQLSET(
             sqlset_name     => 'my_tuning_set',
             populate_cursor => baseline_cursor);

RAT - SQL Tuning Set from 9i trace in wrong order

Hi together
I want to test the impact of some staments on 9.2.0.8 in 11g with Real Application Testing, but the order in the tuning set seems to b wrong (not in the traced order). So i made a small Test Script who is creating a Table, insert Data with a loop and select all.
Steps :
* 9i enable trace level 4
* 9i run the script
* 9i stop the trace
* transfer to 11g
* make an sql tunnig set
* running in the Performance Analyzer Workflow
The first run Oracle makes performance datas from the trace files. In the second run I want to execute the statements from the tuning set in the 11g database. The traced Schema from 9i exists.
In the report after the second run I see the failure that the insert and select statement is not allowed. When i take a look in the SQL Tuning Set i see that the select and insert will be played before the create table ! Also on the view DBA_SQLSET_STATEMENTS.
Is there a way to get the correct order in the SQL Tuning Set like the statement order (create before insert,select) ? Or can Oracle not handle DDL-Statements in the trace ?
Regards Martin

Sql tuning set explain plan

A hypothetical question came up between dbas in the office. We regularly take tuning sets before making significant changes on the DB. Populate from cache. Great little way of checking to see if anything changed. Someone asked if a table T1 was accessed during a given day where we had a tuning set being populated from the cache (no reason for auditing to be on at the time). Well first thing to do is search the sql_statements
select * from DBA_SQLSET_STATEMENTS
where sqlset_name = 'my_sts'
and sql_text like '%select * from t1%'
but no rows returned, so next idea is to query the plan in case a synonym was used
select * from DBA_SQLSET_PLANS
where sqlset_name = 'my_sts'
and object_name = 'T1'
And yes, its there we had a select against the table, the main sql_text in the dba_sqlset_statments view was using a synonym. great, so now we might be able to use this as a alternative audit method (mmv depending on whether you have the diag pack).
Heres the question, can we always be guaranteed an object will be in a plan?

Also, the presence of a SQL statement in the shared pool does not indicate it was run today - you'd need to check the relevant column, something like last_active_time.
More importantly, the absence of a SQL statement from the shared pool does not indicate that it was not run today.
Just that it's no longer in the shared pool.
I'm concious of that when running the populate, even in a busy period our pools last over an hour, with that in mind when Im populating my tuning set, I set the frequency to 10 minutes to poll the cache where distinct IDs and HASHes are overloaded in the tuning set if theyre already there.
http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_sqltun.htm#CACJHDDC
Note that in production systems the time limit and repeat interval would be set much higher. You should tune the time_limit and repeat_interval parameters based on the workload time and cursor cache turnover properties of your system.

Additional licenses reuired for using Sql Tuning Advisor 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

SQL Tuning Advisor on a specific SQL statement

Hi all,
How can I used SQL Tuning Advisor in Oracle EM Database Control to tune a specific SQL statement; i.e. the statement is not any of: Top SQL, SQL Tuning Sets, Snapshots Preserved Snapshot Sets.
Thanks in advance,
Ahmed B.

Hi,
You can use either the automatic SQL tuning features that are accessible from Enterprise Manager Database Console on the "Advisor Central" page or trough SQL*PLUS using the DBMS_SQLTUNE pakage:
-- creating the tuning task
set serveroutput on
declare
l_sql_tune_task_id varchar2(100);
begin
l_sql_tune_task_id := dbms_sqltune.create_tuning_task (
                          sql_id      => '<your_sql_id>',
                          scope       => dbms_sqltune.scope_comprehensive,
                          time_limit => 60,

FINDINGS SECTION (3 findings)
1- SQL Profile Finding (see explain plans section below)
2 potentially better execution plans were found for this statement. Choose
one of the following SQL profiles to implement.
Recommendation (estimated benefit<=10%)
- Consider accepting the recommended SQL profile.
execute dbms_sqltune.accept_sql_profile(task_name => 'TASK_58643',
task_owner => 'SYS', replace => TRUE);
Recommendation (estimated benefit: 99.15%)
- Consider accepting the recommended SQL profile to use parallel execution
for this statement.
execute dbms_sqltune.accept_sql_profile(task_name => 'TASK_58643',
task_owner => 'SYS', replace => TRUE, profile_type =>DBMS_SQLTUNE.PX_PROFILE);
Executing this query parallel with DOP 128 will improve its response time
99.11% over the SQL profile plan. However, there is some cost in enabling
parallel execution. It will increase the statement's resource consumption by
an estimated 14.56% which may result in a reduction of system throughput.
Also, because these resources are consumed over a much smaller duration, the
response time of concurrent statements might be negatively impacted if
sufficient hardware capacity is not available.
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
Number of executions 17494
Percent of total activity 7.2
Percent of samples with #Active Sessions > 2*CPU .63
Weekly DB time (in sec) 614696.04
Projected statistics with Parallel Execution
Weekly DB time (in sec) 704166.9
2- Restructure SQL finding (see plan 1 in explain plans section)
An expensive "UNION" operation was found at line ID 4 of the execution plan.
Recommendation
- Consider using "UNION ALL" instead of "UNION", if duplicates are allowed
or uniqueness is guaranteed.
3- Alternative Plan Finding
Some alternative execution plans for this statement were found by searching
the system's real-time and historical performance data.
The following table lists these plans ranked by their average elapsed time.
See section "ALTERNATIVE PLANS SECTION" for detailed information on each
plan.
id plan hash last seen elapsed (s) origin note
1 209247904 2011-07-12/10:09:08 7.564 Cursor Cache
2 4029269565 2011-07-12/10:20:21 15.374 Cursor Cache original plan
3 4128886984 2011-07-08/11:30:25 42.426 AWR
4 3695555639 2011-07-12/08:30:30 101.459 AWR
Recommendation
- Consider creating a SQL plan baseline for the plan with the best average
elapsed time.
execute dbms_sqltune.create_sql_plan_baseline(task_name => 'TASK_58643',
owner_name => 'SYS', plan_hash_value => 209247904);
ADDITIONAL INFORMATION SECTION
- The optimizer could not merge the view at line ID 3 of the execution plan.
The optimizer cannot merge a view that contains a set operator.
- SQL Profile "SYS_SQLPROF_01306b26f6aa0000" exists for this statement and
was ignored during the tuning process.

<snip>Perhaps no action at all.
You can ALWAYS produce a report that will show "top 5" issues. The question is NOT "do I have an issue reported by a tuning report". Yes you do. Everyone does. Always. Even if you slowest batch job runs in 1.3 seconds and your slowest OLTP transaction completes in 0.0001 second.
The question is "do I have a problem that is serious enough to spend time solving?"
If your average OLTP transaction completes in 3 seconds, how much effort is justified to get a 50% improvement?
How much effort is justified to get that same 50% improvement on transactions that complete in 1.5 seconds? 0.2 seconds?
Beware of Compulsive Tuning Disorder.

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?
Thanks in advance

OraOLEDB not appearing as an option in the 'Providers' list SQL Server 2008

Hi there,
I'm trying to create a linked server to an Oracle 10g database from SQL Server 2008 R2, but the required OraOLEDB.oracle driver is not appearing in the list of providers. We are trying to recreate our prod environment where we use the 11g client to connect to the 10g db, so I downloaded the installed the 11gClient ODADC (11.1.0.7). I have the Oracle folder in my 'Start' menu (Windows 2008 O/S), and it looks like the Oracle install was successful but in the registry (regedit) I don't see Oracle listed as 'software' in the local_machine/software listing.
I set my Oracle home to C:\Oracle and the path under there is
product\11.1.0\client_1
I've also read in some other posts that I should have both a 32 bit and 64 bit Oracle driver installed - I'm assuming that 11g is 64-bit and 9i is 32 bit?
Should I be able to install just the client or do I need to install the Server as well?
Any suggestions?
Thanks in advance for...

I figured this out - we didn't have the 64-bit version of the driver.

SQL tuning for a query

Hello Gurus,
I have 2 tables. One with a million records and the other with 50,000 records.
Both have an account id column. The first table contains all the customer accounts and the second table has all the bad debt accounts.
My problem is I need to update the status column in the first table for all the bad debt records from the second table.
As I’m still a beginner in SQL tuning, can someone please help me write this query effi ciently considering the table sizes.
tables description:
SQL> desc customer
Name Null? Type
ACNTNO NUMBER(8)
STATUS VARCHAR2(6)
SQL> desc badcustomer
Name Null? Type
ACNTNO NUMBER(8)
The sql I could come up with is:
update customer outer
set status='closed'
where acntno exists (select 'X'
from badcustomer
where acntno=outer.acntno);
Thanks for taking time to read this post.
