How to set the heap size in adminstrative console

Hi All,
Please let me know how to increase heap size in weblogic Adminstrative console.
Regards
Madhu

The answer to this depends on whether you're trying to set the heap size for a manager server which is managed by NodeManager, or the admin server.
First click on "Lock and Edit".
If the former, go into "Environment"->"Servers", then click on the server you want to configure. This should start you on the "Configuration"->"General" tab. Now click on the "Server Start" tab. Find the "Arguments" field. Assuming this is blank, put something like the following in the field value:
-Xmx1536m
Then click "Save", then "Activate Changes". When you restart the managed server the next time, it should use those new settings.
If, however, you're trying to set this on the admin server, you can't do this in the admin console at all. In that case, go into $DOMAIN_HOME/bin and edit the "setDomainEnv.{sh,cmd}" script (".sh" if on Unix/Linux, ".cmd" on Windows). Find the line that sets the "MEM_ARGS" variable, like the following on Windows:
set MEM_ARGS=-Xms256m -Xmx512m
Change this line to whatever you want, then restart the admin server.

  • Setting the heap size

    Hi all,
    I wanted to ask you about setting the heap size value.
    How we can calculate the heap size?
    I had problems with the max heap size in my application.
    So I increased the max value to 2048 MB, but I am afraid that
    the same error may come up again some time depending upon the
    usage.
    So how I can find, say for a server having 2 GB RAM,
    how much heap size I should give? I read that there is no defined
    formula to calculate this. But I wanted to get the best way of doing it.
    Please advise,
    Sandeep

    As has already been said, you probably have a leak. However, when trying to gauge the maximum heap you can (not should, but can) use you have to take into account what the server is doing, and its operating system. You do not want your JVM to page. So, for a 2GB server, with no other app on it, I think the "usual" is something like 75% max? Though I really wouldn't take my word for it...it's not my field.

  • Hi, I am using Indesign CS6, How to set the page size in Inches.

    Hi, I am using Indesign CS6, How to set the page size in Inches.

    All fields in InDesign can be entered in any measurement system. So, if you want to make an 8"x10" document and go to File>New Document and the window looks like this:
    …you can type either 8 in or 8" into the Width field like this:
    …and when you move to the next field, it will convert the eight inches into the equivalent number in the unit of measure that it is using at the moment, like this:
    … (203.2 milimeters is the same as 8 inches). You can also enter a different measurement unit into other fields once the file is created, such as the width or height of a frame, or the position of an object in the X and Y coordinates.
    If you would rather just work in inches instead of having to type the inches mark or abbreviation, go to InDesign>Preferences>General and select the Units & Increments tab. There you will see Ruler Units for Horizontal and Vertical at the top of the window. Set them to Inches and all of the fields will display in inches. If you do that to an open document, you will change the unit of measure for that document. If you do it while no documents are open, it will change the unit of measure for any new documents you create. To change the unit of measure for existing documents, you will have to open each and make the change.

  • How to set the frame size?

    Hi,
    Can some one show me how to set the frame size in this program? History: I have created a window and added a button but its to small. So I want to increase the size of the frame to at least 600X400 pixel.
    private static void showGUI() {
            //Create and set up the window.
            JFrame frame = new JFrame("ButtonDemo");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            //Create and set up the content pane.
            Main newContentPane = new Main();
            newContentPane.setOpaque(true); //content panes must be opaque
            frame.setContentPane(newContentPane);
            //Display the window.
            frame.pack();
            frame.setVisible(true);
        }It would be nice if you could show me how to do it.
    Thank you very much for reading this.

    Simply adding
    frame.setSize(new Dimension(600,400));to the end of your code should work perfectly.Or, if you want to do it correctly, .setPreferredSize() on your frame before you .pack() it. The default layout manager for JFrame is BorderLayout, which uses the preferredSize of each component to calculate sizes during the .pack() call.

    But it is not working.....

    That's pretty much all there is, although you could always add a componentlistener and manually not let the size go below your minimum.
    Or you could try overriding setSize...

  • How to set the fix size jframe window

    when I run the jframe ,the jframe window size is very small
    1)how to set the fix size jframe window??
    2)how to set the jframe cannot change the window size??
    thx~~

    1. You can set the size by calling JFrame's method setSize. There are two versions of this method: (1) setSize(int width, int height) and (2) setSize(Dimension d). Note, that when you use this method to set the frame size, you don't have to call JFrame's pack method.
    2. JFrame has a method called setResizable(boolean resizable) which you can call with the argument false.
    Without any ill intent, these questions are regarding something that is very easily answered by looking at the documentation for the JFrame class. I suggest to anyone working with swing to at least look briefly through the base classes they're extending before giving up. In my experience it is always more gratifying to figure things out on my own than asking someone. But please don't take this the wrong way, I respect people who seek out help in order to further their knowledge, instead of just giving up.

  • How to set the stack size for alchemy application?

    Anybody know how to set the stack size for alchemy application?
    If you know, please tell me how to adjust the stack size for alchemy application?

    Hi,
    The stack size is set as public const gstackSize in the alchemy generated code.  You can see this if you build with ACHACKS_TMPS set.  The default is one megabyte.
    One way to change the stack size is to use llvm-dis to disassemble avm2-libc/lib/avm2-libc.l.bc, generating avm2-libc.l.ll, modify the constant, and then use llvm-as to recompile your modified library and overwrite the old one.  These utilities should be in your path if alchemy is set up.

    I think the default heap size is 16MB, as for the GC output:
    these [GC 2598K->2145K(2696K), 0.0035829 secs]
    show the collection of Objects within the eden area of the heap (Short lived Objects),
    the heap size before GC was 2598K and after GC was 2145K and the time taken was
    0.0035829 secs.
    These outputs:
    [Full GC 2713K->2070K(4028K), 0.1933980 secs]
    show the details for a full GC, these are the ones to watch out for, they will
    take longer and the JVM (no mater how many processors) will block during a full
    GC....I.E no server response at all.
    The smaller the heap size the more often a full GC will occur, however the larger
    the heap, the longer the full GC will take.
    One of the new options for jdk 1.3.1 is the -Xincgc option, this will do incremental
    Garbage Collection, overall it will take longer than normal, but the individual
    Full GCs will take less time....so the server is not hung for as long at any one
    time.
    Set -Xms (the minimum heap) to the same as -Xmx (max heap), this increases performance
    as the JVM does not have to repeatedly assign more memory to the heap.

    null. java.lang.OutOfMemoryError
    i'm getting this Error while deploying the application.So wat is the procedure to increase the Heap Size
    Regards,
    Niranjan.D

    Locate opmn.xml on your instance. In file locate section relevant for container you use (i.e. "home"). In next line you can see tags where startup parameters are set. You should add following parameters (this will set heap size on 512Mb)
    -Xms512m -Xmx512m
    For detailed explanation I would recommend you to check following link:

    Hope this help.
