SGA_MAX_SIZE and SGA_TARGET how to set minimum for pools

Hello, we are on 10.2.0.4, Solaris 5.10. We are using ASMM, so SGA_TARGET and SGA_TARGET size are set. Hence, buffer cache, shared pool, large pool and java pool are automatically sized. However, we do not have any minimum values for those. How do I determine what this minimum value should be?
thank you!

HI,
Yes you need size the minimum value for shared pool, buffer cahce tec... else it will start consuming wholeThe documentaion
states:
You need not set the size of any of these components explicitly. By default the parameters for these components will appear to have values of zero. Whenever a component needs memory, it can request that it be transferred from another component by way of the internal automatic tuning mechanism. This transfer of memory occurs transparently, without user intervention.Can you please explain how would it start consuming the entire SGA?

  • Issue creating a database: SGA_MAX_SIZE and SGA_TARGET

    Hello:
    While creating a custom database, I am running into issues with the values I specify for SGA_MAX_SIZE and SGA_TARGET.
    The install manual for the product I am creating the database for says that SGA_MAX_SIZE should be >= SGA_TARGET_SIZE. It also wants a minimum of 1Gig for SGA_Target
    The Database Configuration Assistant defaulted to 0.64GB for SGA_TARGET and 0.168 for SGA_MAX_SIZE (This is clearly against the instruction in the installation manual).
    Who is right? Me or the vendor?
    I read some threads that indicate that the vendor may be wrong.
    venki

    Follow the vendor's instructions.
    DBCA has never in its existence made a correct decision yet. It puts all control files and redo logs into one directory.
    It doesn't create multiple members for the log file groups.
    And its memory management is based on a simple algorithm that has nothing to do with any specific reality.
    DBCA is intended for creating a generic database for generic purposes ... and that it does very very well.

  • How to set password for a zip file and should be checked when reading that

    Hi friends,
    how to set password for a zip file and should be checked when reading that file???
    thanks.
    Praveen Reddy.J

    Heyy man, i think, u did not get my problem.
    all i have to do is:
    i have to create a zip file, and we should secure it with password when creating. and whenever the user wants to open that zip file he should provide correct passowrd otherwise he could not read that file. So, we should check for that also.
    Tanks for reply.

  • How to set value for trim and bleed using jsx script?

    I have tried using bleedoffsetRect but somehow it is not working. Can anybody please help me on how to set value for trim and bleed using jsx script? Any example will be highly appreciated.
    Following is the code I am trying with:
    var _saveName = new File ( root_path +_strFileName+".pdf");
        var _saveOpts = new PDFSaveOptions();
        _saveOpts.printerResolution = 300; 
        var bleedarray = new Array();
         bleedarray[0] =9.00;
         bleedarray[1]=9.00;
         bleedarray[2]=9.00;
         bleedarray[3]=9.00;    
        _saveOpts.bleedOffsetRect = bleedarray;

    I would expect although I've not actually tried this for the bleed off set box to be larger than the artbaord and the first two values to be negative or 0…
    var bleedarray = new Array(-9,-9,artboard.width+9,artboard.height+9);
    Where 'artboard.width' & 'artboard.height' you will have calculated from your file. An Array(9,9,9,9); would not constitute any boxes bounds.

  • Increase SGA_MAX_SIZE and SGA_TARGET

    Hi all,
    I want to increase SGA_MAX_SIZE and SGA_TARGET in 10g. Currently we have
    SQL> sho parameter sga
    NAME TYPE VALUE
    lock_sga boolean FALSE
    pre_page_sga boolean FALSE
    sga_max_size big integer 2384M
    sga_target big integer 2384M
    And we have 16GB RAM in redhat linux 4(32 bit).Oracle 10.2.0.3 DB.
    Because of 32 bit OS, I was not able to increase shmmax more than 4GB.
    In this situation how and how much SGA_MAX_SIZE and SGA_TARGET I can increase?
    Thanks in Advance,
    Sunil

    Hi sunilgln,
    Given the present state of things, you have to take a meassure of how many RAM is used with nothing running but the OS, that will give you the Linux footprint.
    Take note of the amount of physical free memory (using <strong>top</strong> command)
    Later you have to estimate how much swapping are you willing to accept, the SGA you define may be within the ranges of
    FREE MEM*90% and FREE MEM*90+(OS FOOTPRINT*%SWAP MEMORY WILLING TO USE)
    <em>This is a proposal for setting this up, you need to tune and balance load depending on usage.</em>
    Another recommendation, SGA_TARGET is <strong>dynamic</strong>, SGA_MAX_SIZE is not...but you may set SGA_MAX_SIZE to a full allocation and set SGA_TARGET to a percentage that allocation and gradually use it.
    What happens is: the OS will "allocate" a chunk(or chunks) the size given by SGA_MAX_SIZE, but the real usage by the database will be determined by SGA_TARGET.
    Hope this helps you

  • Sga_max_size and sga_target values

    I have an 11g database on windows with 4GB RAM, I have set the MEMORY_MAX_TARGET and MEMORY_TARGET, what should I do with the pre-existing sga_max_size and sga_target values

    memory_target = sga_target + max(pga_aggregate_target, maximum PGA allocated)
    MEMORY_MAX_TARGET = sum of the SGA and instance PGA sizes.
    For Automatic memory management
    set
    ALTER SYSTEM SET SGA_TARGET = 0;
    ALTER SYSTEM SET PGA_AGGREGATE_TARGET = 0;
    Note:
    In a text initialization parameter file, if you omit the line for MEMORY_MAX_TARGET and include a value for MEMORY_TARGET, the database automatically sets MEMORY_MAX_TARGET to the value of MEMORY_TARGET. If you omit the line for MEMORY_TARGET and include a value for MEMORY_MAX_TARGET, the MEMORY_TARGET parameter defaults to zero. After startup, you can then dynamically change MEMORY_TARGET to a nonzero value, provided that it does not exceed the value of MEMORY_MAX_TARGET.
    Note:
    The preceding steps instruct you to set SGA_TARGET and PGA_AGGREGATE_TARGET to zero so that the sizes of the SGA and instance PGA are tuned up and down as required, without restrictions. You can omit the statements that set these parameter values to zero and leave either or both of the values as positive numbers. In this case, the values act as minimum values for the sizes of the SGA or instance PGA.

  • SGA_MAX_SIZE and SGA_TARGET

    DBAs,
    can any one tell me in brief how SGA_MAX_SIZE and SGA_TARGET helps to tune the instance?
    i have gone through with vairous link but still confuse.
    Regards,
    BK

    hi BK,
    SGA_MAX_SIZE is the maximum sizeof the shared global area (system global area), and SGA_TARGET is set when you want to use ASSM (automatic shared memory management) which is a 10g feature.
    You are alos adviced to post oracle version and os.. SGA_TARGET when set, then oracle automatically manages the memory and if not set then you have to set SGA_MAX _SIZE and manually set others memory components accordingly and tune them.
    I hope this helps you in a small manner
    Thanks and Regards

  • How to set View for Completed items inside Tasks?

    How to set button for 'View' and see Completed items or not completed inside Tasks?

    Hi,
    You want to set custom views for Tasks folder so that when we click a view button, it will show all Completed or incomplete tasks, am I correct?
    Which version of Outlook are you using? There are existing views for completed/incomplete tasks in Outlook. In Outlook 2010 and Outlook 2013, we can find the buttons under View tab > Change View. Click Completed button to view all completed
    tasks; Click Active button to view incomplete tasks.
    In Outlook 2007, just click View > Current View to switch between different views.
    If I've misunderstood something, please feel free to let me know.

    How to set sourceURL for MS Access database in other computer?You don't.
    How do you determine the port for the MS Access?You don't.
    Databases like Oracle and MS SQL Server have 'server' software which runs on a server computer. Requests talk to that server software. MS Access does not have a server, so there is nothing to talk to.
    You either must use a DSN or create you own server. For the DSN each client must have a mapped driver to the computer with the database. For your own server search the Sun site for JDBC drivers or use RmiJdbc (http://www.objectweb.org/)

    Hi ,
    I created a survey in CRM Service, in which I added a question with answer as '10 Selection Button Group ('radio button'). And answer has 11 answer options (which means 11 radio buttions).

So, how to set value for radio button in sap crm survey suite???.
