Init.ora parameters for banking application

hi
i would like know guidelines for setting
init.ora parameters for database, to handle
load of 2 million transactions per day,with
RAC setup for high availability.
thanks

  • Bestpractice init.ora parameters for data warehouse in 10gR2

    Hi,
    We moved our 1Tera data warehouse database to linux 64 bit , 8 cpu , 8GB memory, with ASM (non RAC).
    Could you please recommand best practice setting init.ora parameters in 10g
    DW to achive the best performace ?
    I set the following parameters:
    parallel_adaptive_multi_user=TRUE
    parallel_execution_message_size=2152
    parallel_min_server=0
    parallel_max_server=135
    parallel_threads_per_cpu=2
    db_file_multi_block_read_count=64
    pga=900m
    query_rewrite_enabled=true
    star_transformation_enabled=true
    db_block_size=32k
    sga_target=3g
    statistic_leve=typical
    undo_management=auto
    workarea_aize_policy=auto
    db_cache_advice=on
    disk_async_io=true
    2. What setting would you recommand regrading the following parameters in DW (and ASM):
    -- filesystemio_option :none | setall | directIO | asynch
    Thank You.

  • Evolution of init.ora parameters

    Hi Gurus,
    Can someone name the milestones (or important) in the evolution of parameters in init.ora file. I knew for every release certain parameters are relegated, or replaced and few are introduced as new and ofcourse for some the default values are changed. I want to understand the most important changes Oracle has come up at 8i, 9i, 10g and 11g releases.

  • Setting of init.ora file for 500 users

    how to set diffrents parameters in init.ora file
    for 500 user
    (hybrid system)(oltp+dss)
    thanks

    Yeah, it depends and you will need to adjust thoses parameters during the "life" of the database.
    I give you some of my thoughts (that's just thoughts, not a rule => there is no perfect rule) :
    500 users = Unix box i guess so :
    If MTS (dont think u need MTS for 500 users) => SGA = 75% of the RAM of the server
    If NOT MTS (dedicated processes) => SGA = 50% of the RAM
    Say 2GB of RAM on no MTS :
    buffer cache = 900 MB
    shared pool = 100MB to 200 MB
    sort_area_size = 256KB
    something like 50 to 100 RBS (depends on how many users are connected simultaneously)
    for the users which will not do some OLTP operations, you should make few BIG RBS and assign their transactions to them. for thoses users, you probably need a bigger sort_area_size.
    all the tablespaces LOCALLY MANAGED
    backup with RMAN

  • Are there any init.ora parameters which can't be changed at all ?

    DB version: 11gR2
    We have the following two types of initialization parameters
    Dynamic - Which can be changed without a DB bounce (example CURSOR_SHARING)
    Static  - Which can be changed only with a DB bounce (example MEMORY_MAX_TARGET )
    Both types of init parameters mentioned above can be changed with or without a DB bounce. Are there any initialization parameters which cannot be changed at all  with or without a DB bounce?

    Max wrote:
    Oracle documentation which describes init.ora parameters is 'Oracle Database Reference 11gRelease 2'. It doesn't answer my question
    Maybe it does.
    from DB_BLOCK_SIZE
    The value for DB_BLOCK_SIZE in effect at the time you create the database determines the size of the blocks. The value must remain set to its initial value.

  • Recommended  init.ora values for PROD setup

    Hi All,
    -Assuming that I am using a 64-bit version of Oracle,
    -that there is nothing else running on the server,
    -that there will be no other databases on the server,
    -that I have substantially more data on disk than I have RAM,
    -and that I am using 11g. I want to setup a production database 11g. The server specs is OEL 5.6 with 12Gb Ram and a Quadcore CPU.
    There will be 200 users simultaneously accessing the database. I understand that 10g and 11g are "self-tuning".
    So in this regard do I need to still change values in the default init.ora?
    Can you give me sample PROD template of your init.ora?
    Or maybe since my RAM is 12Gb I will just set the "target SGA = 8Gb" and the database will now be good?
    Thanks,
    Yx

    Adding Justin's assumptions

    I Thank you all :)
    You need to understand what the memory is used for. Please read the documentation on SGA and PGA components and parameters and how they impact performance.Yeah I read it already....but it does not clearly explain like what all you did here ;)
    Hmm interesting....I got lots of tips learned. So If I have 500Gb data (im sure it does not include index right?) Broken into the following:
    Table1 300Gb
    Table2 100Gb
    Table3 50Gb
    Table4 30Gb
    Table5 10Gb
    Table6 5Gb
    Others 5Gb ( comprised of hundreds of tables)
    Do I need to have my memory target SGA equal to 500Gb to attain a maximum performance? supposing memory is not a budget constraint?
    Supposing Table6 is the most frequentlly read/accessed and I want to load/cache it all in the memory so I do not need to index this table, how can I do it?
    What is the rule of thumb of PGA size against the size of the table? Maybe 20% sorting of the most accessed table?
    @Justin
    **10 sessions doing data warehouse queries will probably need more PGA than 1000 sessions doing OLTP queries.
    **I'd probably start with a MEMORY_TARGET of 10 or 11G. How about the approx. PGA size dear? :)
    @Hemant
    It is more the amount of data and some factoring for the number (volume) of changes to the data.
    The number of users matters in terms of sizing memory for server processes, and some allocation of the SHARED_POOL_SIZE, not for the DB_CACHE_SIZE component.
    If more users means more distinct SQL statements, the SHARED_POOL_SIZE usage would be greater.
    However, multiple users accessing the same version of the data will be "sharing" one buffer in memory for each block of data being accessed. It doesn't matter if 1 user is reading a block or 8 or 64 or 128 users are reading the same block -- in either case it is one buffer in memory.
    It is only if the block is frequently being changed and concurrently queried, might there be current and a few consistent versions of the buffer being maintained in the SGA.I think in 11g I do not need to set those because it is "self-tuning" right? All I need is the target SGA size. :)
    Given that I will perform a "benchmark" test/simulation on the DEV server. Is there a tool that will gather the right sizing of init.ora parameters? Can I extract it from AWR report?
    Thanks to all again,
    Yxz

  • Init.ora parameters

    Hi,
    Which init.ora parameters are respond for write data from cache to redo logs files? It is possible to set this parameter as time or rather for cache usage?

    Dear,
    The purpose of redo generation is to ensure recoverability. This is the reason why, Oracle does not give the DBA a lot of control over redo generation. If the instance crashes, then all the changes within SGA will be lost. Oracle will then use the redo entries in the online redo files to bring the database to a consistent state.

  • WD ABAP - Reading the URL Parameters for FPM application

    Hi,
    As per the Custom requirment,
    I want to pass URL parameters for WD ABAP application (sap/bc/webdynpro/dbm/app_veh_cus_search) which uses FPM.
    example: sap/bc/webdynpro/dbm/app_veh_cus_search?Customer=12345&fromExternal=true
    I am facing difficulty in reading the URL parameters.
    How to read/get the URL Parameters for an FPM WD ABAP application????
    Observation:
    I tried reading the parameter in Window --> HANDLEDEFAULT method. But could NOT read the Parameters from here for FPM application whereas if I create a Z Custom application then I could read the URL Parameters. so the issue is in reading the URL Parameters for FPM application.
    Kindly support
    Regards,
    Hussain

    Hi Hussain,
    You can do this either with the methods of interface if_fpm_parameter...
    DATA lo_param TYPE REF TO if_fpm_parameter.
    lo_param = cl_fpm_factory=>get_instance( )->mo_app_parameter.
    CALL METHOD lo_param->get_value
        EXPORTING
            iv_key   = parameter_name
        IMPORTING
            ev_value = parameter_value.
    or a more generic approach using class cl_wd_runtime_services...
    cl_wd_runtime_services=>get_url_parameter
    Cheers,

  • What init.ora parameters needed for RMAN,

    Hi,
    We would like to implement RMAN at our site and like to know what are the parameters required in init.ora for using RMAN, where can I find more info regarding the tuning of these parameters ? Please reply..
    Thanks a lot in advance,
    Sreedhar

    Tammy,
    Thanks for your reply. I didn't post the exact question, let me do it again.
    I need to determine the 'large pool' size to be implemented for using RMAN. (We already have RMAN running).
    I need to know what parameters I need to set in init.ora for large_pool to work efficiently in conjunction with RMAN. How do I calculate the required size.
    I found some material on this, here, but it's confusing.
    By default LARGE POOL = 0, unless PARALLEL_AUTOMATIC_TUNING = TRUE, (in which case LP will be set automatically). Also, set LARGE_POOL_MIN_ALLOC to a non-zero value to enable a minimum allocation with LP.
    When I read document (ID 73079.1) it gets more confusing, as whether to take MULTIBLOCK-READ-COUNT value or db_file_direct_io_count into consideration.
    Any help is appreciated.
    Thanks again, Sreedhar

  • How to establish a single init.ora file for 3 node RAC under ASM

    All,
    Our environment is a combination of several different memory sized SUN machines (V880, V490 & 250R).
    Setting up a single init.ora file that encompasses each of the nodes memory into the SGA sizing is our desired setup.
    Though we have established the file, the question is getting each NODE on the RAC to use that single parameter
    file to start its database instead of taking the default init.ora file in the default (asm/dbs) directory.
    As we have performed fail-over testing, upon the restart of instances they have restarted with wrong memory
    definitions that have hung the nodes when it took more memory then what was available and swap space began
    to grow.
    Steps to configure and enable this process is what I am looking for.
    Thanks
    Gerry

    Gerry,
    Here's what we do. Not sure if it is relevant to your situation ...
    (on each node)
    $ cat $ORACLE_HOME/dbs/initrac11d1.ora
    SPFILE='+DATA/rac11d/spfilerac11d.ora'
    (in ASM)
    $ asmcmd
    ASMCMD> ls -la +data/rac11d
    Type Redund Striped Time Sys Name
    Y CONTROLFILE/
    Y DATAFILE/
    Y ONLINELOG/
    Y PARAMETERFILE/
    Y TEMPFILE/
    N spfilerac11d.ora => +DATA/RAC11D/PARAMETERFILE/spfile.267.685170285
    The spfile has all parameters, qualified by node where applicable. For example :
    $ sqlplus / as sysdba

  • Init ora file for 2000 server oracle

    Hi,
    All oracle parameters registry related can be found in the book for window. If you don't see the init which is pointing to it is going to the default. Look in ORACLE_HOME\database

  • Command Line Parameters for Run Application.vi in the LVWUtil

    I am trying to use the "Run Application.vi" located in the LVWUtil.llb.  I am sending a command line similiar to this:
    "C:\WINXP\system32\msiexec.exe" /i "C:\qc data\ZVMS Program Updates\Application Installer\install.msi"
    this command line works from the Start>Run dialog but the Run Application.vi only sees the beginning of the line "C:\WINXP\system32\msiexec.exe" so it opens the windows installler but does not go to the install.msi file and run it.  Does anyone know the correct command line formats for the Run Application.vi to run the entire command line?
    Thanks,
    BethV

    Hello BethV,
    I downloaded the LVWUtil32.zip file from the Windows API Function Utilities (32-bit) for LabVIEW example program.  In that zip file, is a library entitled Winevent.lib, which includes the Run Application.vi.  When you used this VI, I believe the string you passed in as a input had too many quotation marks.  Namely, you do not need quotes around the msiexec.exe call.  I passed the following string into the Run Application.vi and got the expected results:
    C:\WINDOWS\system32\msiexec.exe /i "C:\mymsi.msi"
    Please let me know if it helps.
