How to increase heap size in java code, not using "java -Xms64m "

Im writing a java programme for loading the german dictionary. my dictionary is very huge(around 300000+ words).
while loading the dictioanry im getting error "OutOfMemoryError" .
I found one solution to increase the heap size, but i want to increase the heap size in java programmer itself, not outside jar file. so i could not use "-Xms64m" option of jvm.
Can anyone tell me how can i do this

Can anyone tell me how can i do thisThat option is a startup option for the JVM. That means if your jar is already loaded then you are already too late to try and call it.

    Hi,
    you don't have to stop your database to increase the file size - it's an online operation. If you are more familiar with SQL code here is what you have to do:
    use <SID> /*Put your database name here, e.g. PRD*/
    go
    select file_id, name, physical_name, size
    from sys.database_files
    where type_desc = 'ROWS'
    In the resultset you will find a column called 'name' - that are the logical file names that we need for the increase. If you have a standard installation the names should look like <SID>DATA{1-4}. Next step ist the actual increase of the files:
    /*Replace <SID> with your DB name*/
    alter database <SID> modify file(name='<SID>DATA1', size=25GB) /*25GB ist just an example*/
    alter database <SID> modify file(name='<SID>DATA2', size=25GB)
    alter database <SID> modify file(name='<SID>DATA2', size=25GB)
    alter database <SID> modify file(name='<SID>DATA4', size=25GB)
    Thats it. If you run the first statement again, you will see that the filesize has been increased. You can also check on  filesystem level.

  • How To Increase heap size in Java Studio Creator 2

    Hi,
    I'd like to know how I can increase the heap size in Java Studio Creator 2.
    I already tried editing creator.conf, but it doesn't seem to work...
    Can anybody help me?
    thanks.

    In the servers window of creator, right-click 'Deployment Server' and choose 'View Admin Console'. A new web page comes up with the web interface to the Sun Application Server 8. Type your username and password that you configured during installation. I think default username is admin and default password either admin or adminadmin. After you're in, click 'Application Server' link in the left window, then click 'JVM Settings' tab, then click 'JVM Options' tab. Add new JVM option -Xms512m to start the server with 512MB. Find the -Xmx option and edit it to something larger, provided you have enough memory on your system.

  • How to increase heap size in Java in detail?

    I am writing an java app in eclipse that do need a lot of memory.
    The default
    java -Xms32m -Xmx128mis not enough.
    I want to change it to
    java -Xms128m -Xmx512mI opened the command line in windows xp and changed the current directory to the installing place of jre and jdk.
    But under either directory after I ran the above command, it returns help information like

        .......Have I changed the heap size successfully?
    How can I verify it? I am using eclipse 3.2 running the application.
    Please offer me some help. Many thanks!

    It is showing you the help message, because you forgot to specify a class. When you call the "java" command, you have to say a class name after the -Xms and -Xmx commands.
    So, do this:
    java -Xms128m -Xmx512m classNameWhere className is the main class of your app.
    Best of luck.

  • JGrasp -- how to increase heap size?

    Hello, can anybody tell me how to increase the max heap size in jGrasp?
    Thank you.

    Thanks.. I tried that, but I'm not sure that it
    increased the heap size. I tried using that method
    to set it to 512MB (-J-Xmx512m), and when I open up
    System Properties within jGrasp, it says:
    Free Heap: 7,805,040
    Total Heap: 19,812,352
    Max Memory: 532,742,144That is what you would expect with a 512MB max heap.
    And then I put the following lines of code in my
    program:
         long max = Runtime.getRuntime().maxMemory();
    System.out.println("Runtime.maxMemory():
    ): "+max/1024/1024+" MB");
    And the output that I got was: "Runtime.maxMemory():
    63 MB"You have set the max heap for jGRASP itself, which you
    might need if you are editing some huge files or
    something and jGRASP is running out of heap. Max
    heap for user programs is a different issue. To change
    that, on the compiler settings for the current workspace
    or project, in the "Flags/Args/Main" tab, add Java flags
    like "-Xmx512m" to "Flags2 or Args2" for the "Run" and
    "Debug" rows.

  • How to increase heap size in OC4J .

    you should be able to pass the java heap options when starting the container:
    -Xmx1024M
    So if you are starting the 10.1.3 container from a Windoz command file you could use:
    setlocal
    @echo off
    set ORACLE_HOME=C:/Programs/oc4j-10.1.3
    set JAVA_HOME=C:/Progra~1/Java/jdk1.5.0_07
    set J2EE_HOME=%ORACLE_HOME%/j2ee/home
    %JAVA_HOME%/bin/java.exe -Xmx1024M -jar %J2EE_HOME%oc4j.jar

  • How to increase Heap size at runtime

    And unless there is no reason to be swapped out
    (plenty of physical memory) then it will be swapped
    out.I don't understand this. If there is no reason to
    swap a page back to the disk - e.g., there is plenty
    of available phyiscal memory for some other process -
    then why would the OS bother to swap that page back
    out to the disk?Ok I don't understand the statement either :)
    So obviously I need to rephrase it.
    Page swapping only occurs when needed. If there is plenty of physical memory to hold everything, then swapping does not occur.
    On the other hand if there is not enough physical memory then pages will be swapped out.
    >
    And application can also tell the OS that it nolonger
    wants to use some memory (pages.) But what doesthis
    gain the application? After all if it kept thememory
    and simply did not use it, it would not affectother
    applications. That is because the memory isswapped
    out to the harddrive until needed. So there is no
    need for an application to return memory to the OS.But since virtual memory is finite and there is a
    performance overhead if there is frequent swapping of
    pages into physical memory and out from the disk
    (thrashing), overall performance/throughput degrades.Some what correct. First virtual memory has a finite limit. But that limit itself does not affect other applications.
    Virtual memory in of it self does not cause swapping. If I allocate 1 gig for my application, when my application runs it will not have 1 gig of physical space. Only the memory that is 'touched' is relevant to the OS. So during a time slice it might be the case that only 16k of actual physical memory is used - say 8k for the small piece of code running and 8k for data (an over simplification but appropriate for this discussion.)
    It is rather unlikely, perhaps even impossible, that the entire 1 gig of memory would be swapped into memory during a single time slice.
    If the process' consumption of memory can not be
    streamlined, then that's typically when people go and
    buy more physical memory, no? Or in some cases,
    increasing the amount of virtual memory available to
    the OS can alleviate the problem.There is a difference between requesting memory and using memory. Memory that is used ('touched') is the only thing that has to be in physical memory. If you do indeed use a lot of memory in your application then more physical memory will help. But simply requesting more memory doesn't impact physical memory.

  • How to Increase textarea size in HTML code in WM05

    Hi All,
    I am working on a project where we used JSP & HTML language for User Interfaces.
    My application running on WM2005. In one of the page is having text area with cols=30 and rows=15.
    Here I increased the number of cols to 50, and checked in PDA(WM2005). There was no change in width of the textarea. It was similar with as it was with cols=30.
    But I can see this effect in my LAPTOP.
    Can any body please tell me how to increase the textarea in Pocket PC.
    Regards,
    Babu.

    Hi Babu,
    perhaps you have used a CSS style and this causes your problems? Anyway, the following line works on my PDA without issues:
    <textarea cols="20" rows="5" style="width:30px;">test</textarea>
    Hope this helps!

  • How to increase photo size whilst viewing on HDTV using Airplay?

    Hello,
    I am using a new Apple iphone 4s with IOS 5.1 etc and I am trying to view photos on my HDTV in widescreen format via Apple TV (3rdGen) ... The video playback mirrored from the iphone in 1080P automatically appears in widesreen using the full screen real estate and is awesome!!.... but the photos only 'mirror' using half the screen? Is this the best I can hope for? The same problem is evident trying to view pics from my ipad 2 .... I did notice on an Apple promotional video that a bunch of guys were sat around scrolling through pics on an iphone .... on their HDTV the pics they were viewing from an iphone were displayed in widescreen format just as the video .... any ideas?
    Thanks
    Jon.

    Are the pictures taken with the iPhone in portrait (home button on bottom) or landscape (home button on right or left)?  If the latter the picture should take the full screen, if the prior it will appear in approximately half the screen to maintain image proportions.

    Oracle does not recommend using the SORT_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. SORT_AREA_SIZE is retained for backward compatibility."
    --How can i know the instance is configured with the shared server option or not?This might be a tough question to answer. A shared server configuration may be enabled, but the clients may still connect using dedicated sessions, in which case PGA_AGGREGATE_TARGET would still apply.
    From
    http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2088.htm
    V$SESSION includes a column named SERVER which will contain one of the following for each of the sessions: DEDICATED, SHARED, PSEUDO, or NONE. As a quick check, you could query V$SESSION to see if any sessions are connected using a shared server connection.
    From:
    http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/manproc.htm
    There are several parameters which are used to configure shared server support, as well as several views to monitor shared server.
    As Robert mentioned, when the WORKAREA_SIZE_POLICY is set to AUTO, the SORT_AREA_SIZE setting is not used, unless a shared server configuration is in use.
    --What default value is WORKAREA_SIZE_POLICY and SORT_AREA_SIZE ?From:
    http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams157.htm
    "Setting PGA_AGGREGATE_TARGET to a nonzero value has the effect of automatically setting the WORKAREA_SIZE_POLICY parameter to AUTO. This means that SQL working areas used by memory-intensive SQL operators (such as sort, group-by, hash-join, bitmap merge, and bitmap create) will be automatically sized. A nonzero value for this parameter is the default since, unless you specify otherwise, Oracle sets it to 20% of the SGA or 10 MB, whichever is greater."
    Actually I am facing performence issue since long time till now i did not get the solution even i have raised SRs but i could not.When the issue occur system seems hang.what i monitored whenever hdisk0 and hdisk1 use 100% the issue occur.
    Regards,
    SajidWhen you say that you have had a performance issue for a long time, is it a performance problem faced by a single SQL statement, a single user, a single application, or everything on the server? If you are able to identify a single user, or SQL statement that is experiencing poor performance, I suggest starting with a 10046 trace at level 8 (wait events) or level 12 (wait events and bind variables) to determine why the execution appears to be slow. If you have not yet determined a specific user or SQL statement that is experiencing performance problems, you might start with either a Statspack Report or an AWR Report (AWR requires a separate license).
    If you believe that temp tablespace usage may be a contributing factor to the performance problem, you may want to periodically run this query, which will indicate currently in use temp tablespace usage:
    {code}
    SELECT /*+ ORDERED */
    TU.USERNAME,
    S.SID,
    S.SERIAL#,
    S.SQL_ID,
    S.SQL_ADDRESS,
    TU.SEGTYPE,
    TU.EXTENTS,
    TU.BLOCKS,
    SQL.SQL_TEXT
    FROM
    V$TEMPSEG_USAGE TU,
    V$SESSION S,
    V$SQL SQL
    WHERE
    TU.SESSION_ADDR=S.SADDR
    AND TU.SESSION_NUM=S.SERIAL#
    AND S.SQL_ID=SQL.SQL_ID
    AND S.SQL_ADDRESS=SQL.ADDRESS;
    {code}
    The SID and SERIAL# returned by the above could then be used to enable a 10046 trace for a session. The SQL_ID (and CHILD_NUMBER from V$SESSION in recent releases) could be used with DBMS_XPLAN.DISPLAY_CURSOR to return the execution plan for the SQL statement.
    You could also take a look in V$SQL_WORKAREA_ACTIVE to determine which, if any, SQL statement are resulting in single-pass, or multi-pass executions, which both access the temp tablespace.

  • Increasing heap size

    Hi,
    I am working on a java program that do parsing of large XML files in the order of 40 - 50 MB and put it in database. when i execute the program it is taking a lot of time to get completed(around 10 hrs)
    I tried to increase the heap size, but could not find a corect heap size for my system.
    Will the problem be solved if i increase the heap size? if so is there any guidelines for setting the heap size?
    Thanks,
    Prasanna

    Are you using the DOM or the SAX parser? For very large files you should always use the latter, then the odds are heap storeage won't be an issue.
    Also, as yawmark says, think about database transactions. You should probably do a commit after every few records are inserted, otherwise the rollback buffer in the database engine can get huge. It could be the bottleneck isn't in the java program at all.

  • How to increase the size (Length and width)  of check box

    Hi All,
    I have to increase the size of ( width and length) of check box, I have revised to check box topic in dev guide but didnt find any clue, i have also tried to use CCStyle class but that is also not working, I would appreciate if some can help me out on this. Thanks in advance , let me know if any clarification required.
    Thanks
    Pratap

    Hi Pratap ,
    I honestly don't know how to increase the size
    But i am giving you an alternate solution : we can create two Images with check box type 1 ) with checked
    2 ) with unchecked . ( you can create image of any size ) and get them displayed on OAF screen dynamically using switcher case .
    Dynamically displaying image will give the illusion of check box being checked and unchecked .
    keep this image moved to following media directory
    eg : /oraapp/mfgtestcomn/java/oracle/apps/media .
    Implement the switcher case , add the fire action to this Image Column , create a transient attribute and attach to this
    column . Depending on the value returned by transient attribute display the image on the column .
    Let me know if its not clear .

  • How to change heap size in control panel

    i've already searches previous post about this problem but still i couldnt get it to work or maybe i'm doing it wrong. i did it a lot of times but still i couldnt get it. can anybody show me how exactly to change the java heap sizes.
    and is it possible to display the current java heap size of my jvm?
    tnx in advance
    nashstanley

    You can change the heap by using an option to to the java command, when Java starts up. If you're starting an applet or a Web Start app(applies only to applets or Web Start) then use the Java Control Panel's Java tab to set a value.
    The syntax (in all cases) is defined in the documetation for the java command.
    There are a number of ways to see the heap size, none of which is "standard" Java, and they vary depending on the specifics of which Java you're running and what you're doing. See:
    http://www.google.com/search?q=display+java+heap+size
