To tune the SGA parameters is something equivalent to knowledges for a complete course. Really the question is so wide to answer and overall for you that you are new to Oracle. Some people does not like to read documents but in this case you will have to do it.

    Please try this link.

    But before doing this, check for all the probabilities as it requires lots of data and traces to do the parameter tuning.

  • How to set query parameters to i5Grid

    Hello Everyone,
    I am working on creating i5Charts.
    I mapped query template and display template to i5Chart template but I need to pass the query parameters dynamically.
    How to set query parameters to i5Grid?
    Pls help with syntax.
    Thanks.
    Regards,
    Minakshi

    Hi Minakshi,
    Yes you can try the first 2 options listed by Rohit, the 3rd one however is not supported.
    The below syntax should work for you:
      1.  gridObject.getQueryObject().setRowCount(<Value>);
      2.  gridObject.getQueryObject().setParameter("RowCount", <Value>);
    You can check the documentation at the following link:
    http|s://<host>:<port>/XMII/JSDOC/i5ChartAllClasses.html
    You could also use the script assistant to check for the JS methods.

  • How to set the POV in WebAnalysis when data source is HFM?

    Hi Every one..
    Could any one tell how to set pov in web analysis when data base is HFM. And hoe to make the report Dynamicall (Current Pov Member like in FR). for this if use Essbase Ican get it it easiliy by using Subtitutional variable but is ti possible fo rHFM.
    Thnaks in advance
    Rao

    yeas agree with sanakar,
    this field which shankar is talking about must be entry date (if u delta timestamp is date, u will also have to mention this table field name in definition of delta), this means that this field will catch last change to the record, so that it will be delta enabled based on the latest change date. This is very important becuase if u use date like posting date to the delta then back dated posting will not captured in to the delta, as delta for this back date is already been done.
    Hope u understand this.

    would you please explain to me what
    String[] tokens = line.trim().split("\\s*,\\s*")"\\s*,\\s*" is a regex where \\s means whitespace and the * means "any number of".
    so \\s* means that it will grab all the whitespace if there is any.
    trim() removes white space from the beginning and end of the string.
    dont put a comma in the name.
    spaces allowed: "jane doe, 12-14-09, 428438, 6, 388473, 7, 187374, 3"
    it was just a recommendation. breaking it into separate lines would be fine.

  • Labview How to specify 1d array of clusters as data types for variant to data

    Hi, I'm new to labview. Can anyone tell me how to specify 1d array of clusters as data types for variant to data?

    First of all, you should be sure that there is such a data type within the variant; otherwise, you will run into errors.
    I recommend you to create the cluster and create a type definition from it. Then drop an array shell from the array palette and drop the cluster type into that array.
    Connect that constant to the data type input of the Variant To Data function.

  • I am thinking of buying a iPad but my main desktop machine uses Windows 7 and MS Office.  How easy or difficult is it to transfer data files between the iPad and Windows?  Are there obvious problems or the need for some form of conversion programs?

    I am thinking of buying a iPad but my main desktop machine uses Windows 7 and MS Office.  How easy or difficult is it to transfer data files between the iPad and Windows?  Are there obvious problems or the need for some form of conversion programs?
    Many thanks for any advice.
    David

    You don't need conversion programs, iTunes can copy most of your content over to the iPad via the file sharing section, and some apps also support Dropbox, email attachments, transfer via your wifi network. There are a number of apps that you can get that support Microsoft office file (microsoft don't make an app versions of their software) e.g. from Apple there are Pages (word support), Numbers (excel) and Keynote (powerpoint), and from third-parties there are apps such as Documents To Go and QuickOffice HD

  • How to set memory size for JRE

    hi all,
    Is there anyone know how to set the JRE memory size?
    My run my applet application onto browser and I want to increase to size of memory. Such as -ms 128m -mx256m.
    please help.
    regards,
    elvis

    The suggestion could be convert applet into WebStart application which is quite similar to applet (at least
    it is distributed similar way, resides within sandbox etc) but allows to specify memory size as you requested.

  • How to set the maximum heap size on a deployed application?

    I�m running a fairly large java application and am getting java.lang.OutOfMemoryError. I could increase the heap size in my development environment to eliminate this error. However, I don�t know how to set this in a deployed application. We are currently using ant to build our software.
    Another question, when I execute a statement such as java �Xmx512M �cp app.jar. Is it correct to say that the application in app.jar will use to a maximum of 512MB of memory when running?
    Thank you everyone for your help!

    But first, when you say "a deployed environment" do you mean an executable .jar file? This is what I'm using.The term "deploy" is commonly used to refer to deploying an ear file or a war file on an application server.
    I would assume that there is some entry you can include in the .jar's
    Manifest.mf file to specify the maximum memory, but I can't find an example of the entry. <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6197671"></a>

  • How to set the default maximum size for java's heap?

    Hi!
    Im trying to set the default max size for the java heap - but not from the command line.
    I would like to set it higher as default on my computer.. how can I do that?
    thanks!

    >
    ...You may increase the memory heap only when you're launching a new JVM.>Much like IWantToBeBig does.
    OTOH, it this is an app. with a GUI, it is easier to launch it using webstart, and request extra memory in the JNLP descriptor (the webstart launch file).
