How to learn abt performance tunning...

Hi ,
Is there any way so I can learn tunning in a flash,
anyway I know the concept of Oracle architecture,sql,backup and recovery bust still not able to give proper time to performance tunning plz do suggest me thath how to achieve it and plz provide me the link where I can get learn things without going into big 1000 pages book.
very warm regards : Alok Kumar ...

As for as tuning concern, I recommend you to read following books,
1. Cary Milsap's, Oracle Performance.
2. Don Tow's, SQL Tuning
3. Tom Kyte's, Expert one on one.
4. Jonathan Lewis, Buddiling Effective Database.
Apart from the above books, you can also visit their respective site to get more info about performance tuning. http://asktom.oracle.com, www.hotsos.com,http://www.jlcomp.demon.co.uk, www.evdbt.com, www.oraperf.com and etc.
My recommendation would be start learning about:
SQL Tuning
Join Methods
tracing event 10046,10053 and reding execution plan & tkprof.
wait events and how to spot the error.

How to do Performance tunning in OBIEE

Hi All,
We are using OBIEE 10.3.4 version on windows envorinment .In our OBIEE project we are using 9 reports my requriment is we need to do performance tunning for OBIEE side.For eace report accessing its taking around 80 sec.We need to decrease these accessing time,is there any possibility to access all the reports with less response time in OBIEE side.
Could you anyone suggest how to do performance tunning in OBIEE side.
Thanks,
Vijay.

Vijay,
Plz refer

http://prolynxuk.com/blog/?p=173
http://businessdecisionsystems.com/blog/?p=486
Here is the section from the BIEE admin guide:
=======================
Usage Examples
This section provides a few examples of how to use Oracle hints in conjunction with the Oracle BI Server. For more information about Oracle hints, refer to the Oracle SQL Reference documentation for the version of the Oracle server that you use.
Index Hint
The Index hint instructs the optimizer to scan a specified index rather than a table. The following hypothetical example explains how you would use the Index hint. You find queries against the ORDER_ITEMS table to be slow. You review the query optimizer's execution plan and find the FAST_INDEX index is not being used. You create an Index hint to force the optimizer to scan the FAST_INDEX index rather than the ORDER_ITEMS table. The syntax for the Index hint is index(table_name, index_name). To add this hint to the repository, navigate to the Administration Tool's Physical Table dialog box and type the following text in the Hint field:
index(ORDER_ITEMS, FAST_INDEX)
Leading Hint
The Leading hint forces the optimizer to build the join order of a query with a specified table. The syntax for the Leading hint is leading(table_name). If you were creating a foreign key join between the Products table and the Sales Fact table and wanted to force the optimizer to begin the join with the Products table, you would navigate to the Administration Tool's Physical Foreign Key dialog box and type the following text in the Hint field:
leading(Products)
So, the table names "order_items" and "products" in the above documentation will not be the same after BIEE puts aliases on them.
============
Hope this is useful..

How to do performance tunning

Hi,
Can any one help me how to do performance tunning.I was given two scripts which contains more UNION clauses.

Hi,
What version of Oracle are you on? If you have Oracle 22S (the S is for "Sentient"), there's one way:
SCOTT@ORA22S> set autotrace traceonly explain
SCOTT@ORA22S> ed
Wrote file afiedt.buf
1 select *
2 from test
3* where test_date > date '2001-01-01'
SCOTT@ORA22S> /
Execution Plan
0    SELECT STATEMENT Optimizer=ALL_ROWS (Cost=40656 Card=1071132 Bytes=163883196)
1 0   TABLE ACCESS (BY INDEX ROWID) OF 'TEST' (TABLE) (Cost=40656 Card=1071132 Bytes=163883196)
2 1     INDEX (FULL SCAN) OF 'TST_CUSTOM_03' (INDEX) (Cost=6785 Card=1071132)
SCOTT@ORA22S> alter session set sql_go_fast = true;
Session altered.
SCOTT@ORA22S> /
Execution Plan
0    SELECT STATEMENT Optimizer=ALL_ROWS (Cost=9979 Card=1071132 Bytes=163883196)
1 0   TABLE ACCESS (FULL) OF 'TEST' (TABLE) (Cost=9979 Card=1071132 Bytes=163883196)Unfortunately Oracle 22S may not be available for a while. Until then you may have to listen to Billy ;-)

BADIs
Business add-ins are enhancements to the standard version of the system.
Business Add-In is a new SAP enhancement technique based on ABAP Objects.
They can be inserted into the SAP system based on specific user requirements.
Each Business Add-In has:
at least one Business Add-In definition
a Business Add-In interface
a Business Add-In class that implements the interface
In order to enhance a program, a Business Add-In must first be defined
Subsequently two classes are automatically generated:
An interface with IF_EX_ inserted between the first and second characters of the BADI name.
An adapter class with CL_EX_ inserted between the first and second characters of the BADI name.
The Application developer creates an interface for this Add-In.
There are multiple ways of searching for BADI.
Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
Finding BADI Using SQL Trace (TCODE-ST05).
Finding BADI Using Repository Information System (TCODE- SE84).
1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for CL_EXITHANDLER=>GET_INSTANCE.
Make sure the radio button In main program is checked. A list of all the programs with call to the BADIs will be listed.
The export parameter EXIT_NAME for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter INSTANCE will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
2. Start transaction ST05 (Performance Analysis).
Set flag field "Buffer trace"
Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)
Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.
Push the button "Deactivate Trace".
Push the button "Display Trace".
The popup screen "Set Restrictions for Displaying Trace" appears.
Now, filter the trace on Objects:
V_EXT_IMP
V_EXT_ACT
Push button "Multiple selections" button behind field Objects
Fill: V_EXT_IMP and V_EXT_ACT
All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.
So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA
3. Go to Maintain Transaction (TCODE- SE93).
Enter the Transaction VD02 for which you want to find BADI.
Click on the Display push buttons.
Get the Package Name. (Package VS in this case)
Go to TCode: SE84->Enhancements->Business Add-inns->Definition
Enter the Package Name and Execute.
Here you get a list of all the Enhancement BADIs for the given package MB.

Tools in Performance Tunning

What are the tools in performance Tunning in ABAP/4
Thanks Regards,
Kumar

Hi kumar,
Tools provided for Performance Analysis
Following are the different tools provided by SAP for performance analysis of an ABAP object
Run time analysis transaction SE30
This transaction gives all the analysis of an ABAP program with respect to the database and the non-database processing.
SQL Trace transaction ST05
The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on the SPFLI table in our test program is mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use.
how to perform sql trace:
Poorly written SQL statements have the greatest impact on application performance. An SQL
statement using which an Oracle database system reads and/or sorts thousands or even millions of
rows of data can bring the database to a standstill. Indexes should be used properly to prevent such
situations from occurring. To analyze such problems you should use the SQL Trace (TCode ST05) to
with database access operations.
CAUTION
Only one person can perform an SQL trace at a time. Remember to turn off the
trace when you are finished. SQL trace slows the system down.
1. Using SQL Trace
1. Open a program that you want to analyze, in the editor, so that it is ready and waiting to be
executed.
2. Open a new session using the menu path System   Create session.
3. Run transaction ST05 (enter /nst05-zero-five, not oh-five in the Command field, or choose
the menu path System Utilities Performance Trace).
4. Then the initial screen of the test tool appears.
The status of the Performance Trace is displayed in the lower part of the screen. This status tells you
three things namely
Whether any of the Performance Traces are switched on
The users for whom Performance Trace is enabled
The user that switched the Performance Trace on
If the trace is switched on you must switch it off before you can proceed. There are two cases in
which the trace needs to be switched off. They are
If the trace was started within the past hour, it is possible that it is still being used. Contact the
indicated user or try again later
If the trace was started hours or days ago, the user probably left it on by mistake and it can be
safely turned off
To turn off the trace, press the Trace Off pushbutton.
5. The initial screen has various trace functions such as SQL Trace, Enqueue Trace, RFC
Trace
6. Select SQL Trace.
7. There are various options under which trace can be switched on. They are
If you want to switch on the trace under your user name, choose Trace on.
If you want to switch on the trace for another user or user group, choose Trace on for user.
To enter a single user, specify the user name.
To enter a user group, specify a search pattern (you can use the normal wildcards).
If you want to change the user or user group, switch off the Performance Trace and then restart it,
entering the new users or user group.
8. Now switch back to the window containing your editor session (the one with your program
waiting to be executed).
9. Press F8 to run your program.
Note Just press F8 and do nothing. Do not even press the Back button.
10. When your program has run and the hourglass is no longer displayed, switch back to the trace
window.
11. Press the Trace Off pushbutton.
12. Once Performance Trace is switched off, you can analyze the data
Using Runtime Analysis Tool (SE30)
1. You can open the Runtime Analysis tool as follows:
To start from Choose
Any screen System   Utilities   Runtime Analysis   Execute
Initial screen of ABAP
Workbench
Test   Runtime Analysis
Initial screen of ABAP Editor Program   Execute Runtime Analysis
ABAP Editor Utilities   More utilities   Runtime Analysis
2. In the simplest case, you would enter a short description and a measurement object
(transaction, program, or function module) to run the analysis in the current session.
3. In the Measurement restrictions group box, you can make more specific restrictions for the
measurement. For example, you may want to include only certain statements or time periods.
(For further information refer section 3. 0).
4. To start the measurement, choose Measure runtime. From the initial screen, you can
specify whether the analysis should run in the same session or in a parallel session using the
Enable/Disable button in the In parallel session group box.
5. Run the transaction, program, or function module as normal.
6. Return to the initial screen of the Runtime Analysis transaction. To do so, either leave
transaction, program, or function module as normal, or start the runtime analysis again.
7. The name of the performance data file that has just been created is displayed at the bottom of
the initial screen. The file created by the system is added to the list of performance data files.
You can now analyze, print, or delete the file, or save it locally. The Performance file group
box contains options for analyzing performance files. (For further information refer sections 4.
0 and 5. 0)

keerthi

Please help me how to improve the performance of this query further.

Hi All,
Please help me how to improve the performance of this query further.
Thanks.

Hi,
this is not your first SQL tuning request in this community -- you really should learn how to obtain performance diagnostics.
The information you posted is not nearly enough to even start troubleshooting the query -- you haven't specified elapsed time, I/O, or the actual number of rows the query returns.
The only piece of information we have is saying that your query executes within a second. If we believe this, then your query doesn't need tuning. If we don't, then we throw it away
and we're left with nothing.
Start by reading this blog post: Kyle Hailey &raquo; Power of DISPLAY_CURSOR
and applying this knowledge to your case.
Best regards,
Nikolay

Query Performance Tunning

Dear Experts,
I am executing a query which is build on a Multiprovider. The execution time is approx. 12 mins, again if I enable a dimension to analyze it takes another 15 mins.
The technical details of the query are:
1) The multiprovider fetches data from three different Cubes.
2) It contains three diff characteristics out of which one is having a 10 level hierarchy and one is having a 2 level hierarchy. Both the hierarchies are externally maintained.
3) It contains KPIs which calculate the sales on diff time lines such as CM MTD, LM MTD, CY YTD, LY YTD with the help of a customer exit.
4) It converts the quatities in alt unit of measures through an exit.
Kindly suggest for performance tunning. How shall i achieve min query execution time??

Can any one tell abt performance in obiee

How to improve the performance of a report
How to improve the performance in UI Level
thx a lot in advance

Hi,
There are multiple other ways to fine tune reports from OBIEE side itself:
1) You can check for your measures granularity in reports and have level base measures created in RPD using OBIEE utility.
http://www.rittmanmead.com/2007/10/using-the-obiee-aggregate-persistence-wizard/
This will pick your aggr tables and not detailed tables.
2) You can use Caching Seeding options. Using ibot or Using NQCMD command utility
http://www.artofbi.com/index.php/2010/03/obiee-ibots-obi-caching-strategy-with-seeding-cache/
OR
http://hiteshbiblog.blogspot.com/2010/08/obiee-schedule-purge-and-re-build-of.html
Using one of the above 2 methods, you can fine tune your reports and reduce the query time.
Also, on a safer side, just take the physical SQL from log and run it directly on DB to see the time taken and check for the explain plan with the help of a DBA.
Hope this is useful...
Thanks

How to improve the performance of adobe forms

Hi,
Please give me some suggestions as to how to improve the performance of adobe form?
Right now when I' am doing user events it is working fine for first 6 or 7 user events. From the next
one it is hanging.
I read about Wizard form design approach, how to use the same here.
Thanks,
Aravind

Hi Otto,
The form is created using HCM forms and processes. I' am performing user events in the form.
User events will doa round trip, in which form data will be sent to backend SAP system. Processing will
happen on the ABAP side and result will appear on the form. First 6 or 7 user events works correctly,
the result is appearing on the form. Around 8 or 9th one, the wait symbol appears and the form is not
re-rendered. The form is of size 6 pages. The issue is not coming with form of size 1 page.
I was reading ways to improve performance during re-rendering given below.
http://www.adobe.com/devnet/livecycle/articles/DynamicInteractiveFormPerformance.pdf
It talks about wizard form design approach. But in SFP transaction, I am not seeing any kind of wizard.
Let me know if you need further details.
Thanks,
Aravind
