How to do Performance tunning in OBIEE RPD level

Hi All,
We are using OBIEE 10.1.3.4 version on Windows envorinment, currently we are facing performance issues for my reports.For fetching one month data its taking around 9 mins ..so we are planning ,how to reduce these response time .Could you pls suggest me what are possiable ways to do performance improvement in OBIEE level..Here for each day we are gettng around 5 lacks feed into our DB.

Hi
first thing is to check the same query int he data base and see the response time. if this is taking the same amount of time as the obiee reporting tool, then that matters to think with dba to create some materiazlied views on the top of the transactional data and maintain the aggreated data.
hope you understand.
Cheers.

    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,

    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..

    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)

    Hi
    At RPD level , can anyone please help on uderstanding how to use the variable manager.
    thank you

    Hi,
    System session variables:
    System session variables have reserved names, that cannot be used for other kinds of variables (such as static or dynamic repository variables and non-system session variables).
    e.x:
    1)
    if u want to get and display user login ID,group,timezone...Date and time...etc... can be done by using session variable
    2) Exteranl application integration ( java -jsp) by using go url.
    here u can specify the session variable and it will passed into Java apps.
    3) setting log level by using session varaible
    4) u can use it report tittle/header..etc
    for more:

  • 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 performance tune this query

    I need some inputs on how to do performance tuning on this query to improve performance.
    It takes around 45 secs to run. Is it possible to make any improvements in this by putting hints or writing in another way?
    select count(*)
    as nCount from A ,
    B ,
    C
    WHERE A.COL1 = B.COL1 AND
    A.COl2 <> 'COM' AND
    B.COL2 = C.COL1 AND
    B.COl3 IS NULL AND
    B.COL4 = 'TEST'
    This is the query plan:
    Operation Object Name Rows Bytes Cost Object Node In/Out PStart PStop
    SELECT STATEMENT Optimizer Mode=CHOOSE 1 51
    SORT AGGREGATE 1 37
    HASH JOIN 48 K 1 M 51
    TABLE ACCESS FULL A 68 K 998 K 32
    NESTED LOOPS 98 K 2 M 5
    TABLE ACCESS BY INDEX ROWID B 142 K 2 M 4
    INDEX SKIP SCAN XIF37B 142 K 6
    INDEX UNIQUE SCAN XPKC 1 5

    Mcka
    As well as EXPLAIN PLAN, let us know what proportion of rows are visited by this query. It may be that it is not using a full table scan when it should (or vice versa).
    And of course we'd need to know what indexes are available, and how selective they are for the predicated you have in this query ...

  • Performance Tuning in OBIEE

    Hi Friends,
    Please share me the techniques we follow to get better performance in OBIEE.

    You would have mention that at first.
    If you read the given links you may not ask the question again. You need to know the difference between before the calculation and after the calculation.
    Anything After the calculation is more cost; we can say any complex or frequent calculations in reports show whole database data in the report etc are come under this.
    More over in OBIEE Performance is starts from RPD.
    Or else follow the best practices from Oracle ;)
    Hope this helps (but nothing)

  • 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)

  • How to create stored procedure directely in RPD

    Hi Gurus,
    I am trying to create stored procedure directly in physical table in rpd level in OBIEE.for this one i have gone through below website.
    http://obiee101.blogspot.com/2011/01/obiee-using-mssql-stored-procedure-as.html
    in that blog they mentioned to write some query which is...........
    EXEC [DATABASE_NAME].[SCHEMA_NAME].[PROCEDURE_NAME]
    in above query i am not getting what is DATABASE_NAME,SCHEMA_NAME,PROCEDURE_NAME
    can any one elobrate this one

    Hi nath,
    Firstly are you using MYSQL or Oracle as the database,if its oracle database then follow this
    http://obiee101.blogspot.com/2008/01/obiee-using-oracle-stored-procedure-to.html
    http://oraclebizint.wordpress.com/2008/02/20/oracle-bi-ee-101332-executing-stored-proceduresfunctions-before-reports-before-report-triggers-and-global-temporary-tables/
    EXEC [DATABASE_NAME].[SCHEMA_NAME].[PROCEDURE_NAME][DATABASE_NAME] --> is the database name your creating your procedure
    [SCHEMA_NAME]-->is the user with which your creating
    [PROCEDURE_NAME] --> the name given to procedure
    You dont know how to get those run this SQL in TOAD and see select sys_context('userenv','db_name'), sys_context('userenv','session_user') from dual
    (OR) open you connection pool properties window in RPD,you will get the DB name and the user name as the schema name
    hope answered your question.
