In Japanese locale setVisible(true) consumes large memory

In JAPANESE locale - Swap space/memory usage grows enormously when setVisible(true) method is called.
Problem :
We are developing / converting a product in JAVA built with AWT components in JAPANESE locale. While testing our product, we observed that memory usage (Total VSS column in EnglishResult.txt & JapaneseResult.txt) and Swap space used growing continuously using ?GLANCE? tool, and it was found that setVisible(true) (For any component like Frame, Dialog etc.,) method consumes large amount of memory.
To ensure this problem, the following ?Operation Memory? test was carried out with a sample application in the below mentioned combination of configuration and platforms.
Java Language : JRE 1.3.1 (Hotspot Client) , JRE 1.2.2 , JRE 1.1.8
Locale : Japanese (ja , ja_JP.PCK , ja_JP.UTF-8 , ja_JP.EUCJP , Japanese)
OS          : Solaris 8 ? 256 MB RAM , Swap Space 1 GB
Operation Memory:
1.     Execute the application
2.     Press the ?Show? button
3.     After a dialog is appeared , press the ?Hide? button
4.     Repeat the steps 2 & 3 for 3 times.
5.     Repeat step 4 for 3 times.
The data is collected at the following points using GLANCE tool and the result is shown in EnglishResult.txt (Data of English Locale), JapaneseResult.txt (Data of Japanese locale).
1.     After Step 1
2.     After Step 4 ( 3 times)
In the attached result it is found that for every 3 times of opening and closing the dialog , there is an increase of 1 MB of swap space used & Total VSS , where as in the original product that we have developed , for every opening and closing of dialog there is an increase of 7MB ,
We observed the ?memory growing? behavior in all JRE versions and all Japanese locales .How ever we attaching data collected only in JRE 1.3.1, ja_JP.EUCJP, Solaris 8.
using GLANCE tool.
1)ResultJapanese.Txt ? Data collected in Japanese locale
2)ResultEnglish.Txt - Data collected in English Locale
This behavior is NOT observed if the locale is set to English.
Kindly suggest us to overcome the above said problem in JAPANESE locale.
Sample Java Code (Mem.java)
import java.awt.*;
import java.awt.event.*;
public class mem
     public static void main(String arg[])
          showframe sf = new showframe();
          sf.setSize(300,300);
          sf.show();
class showframe extends Frame implements ActionListener
     Button b1,b2;
     tpframe tpf ;

          tpf = new tpframe();
          b1 = new Button("show");
          b2 = new Button("hide");
          setLayout(new FlowLayout());
          add(b1);     add(b2);
          b1.addActionListener(this);
          b2.addActionListener(this);
     public void actionPerformed(ActionEvent ae)
          if(ae.getSource()==b1)
               tpf = new tpframe();

          tx1 = new TextField("ONEONE");
          tx2 = new TextField("ONEONE");
          tx3 = new TextField("ONEONE");
          tx4 = new TextField("ONEONE");
          p1.setLayout(new FlowLayout());
          p1.add(lb1);
p1.add(tx1);p1.add(tx2);
p1.add(tx3);p1.add(tx4);

I have the same problem!
Our program chews up memory like there is no tomorrow when opening and closing frames....
I will try to start a new thread in this forum explaining our problems a bit more in depth. I have a strange feeling that the garbage collector doesn't do it's job as supposed to.

  • CLOB processing consuming large memory in temp tablespace

    We are having a stored procedure, which is called from a Java process to enqeue a message in to AQ. The input for the procedure is CLOB.
    In some installations where oracle standard editions is used, the temp tablespace is growing in large volumes and the only process accessing the temp tablespace is the procedure. Oracle version is 9i 9.2.0.5.0
    We are doing a trim on the clob variable inside the procedure. Will that cause any issues like this ?
    Procedure is as below
    procedure enq_msg
    (queue_name varchar2, msg_text in clob,p_result out number) as
    queue_options DBMS_AQ.ENQUEUE_OPTIONS_T;
    message_properties DBMS_AQ.MESSAGE_PROPERTIES_T;
    message_id RAW(16);
    v_msg_text               clob default msg_text;
    v_queue_name          varchar2(40) deafult queue_name;
    BEGIN
    v_msg_text := trim(v_msg_text);
    v_queue_name := queue_name;
    DBMS_AQ.ENQUEUE(queue_name => v_queue_name,
                             enqueue_options => queue_options,
                             message_properties => message_properties,
                             payload => v_msg_text,
                             msgid => message_id
         commit;
         p_result := 0;
    exception
    when no_data_found then
    p_result := 1;
         rollback;
    when others then
         rollback;
    p_result := sqlcode;
    END enq_msg;

    Is there a reason you have v_msg_text and v_queue_name defined? You can use queue_name directly in the call to dbms_aq.enqueue and also payload => trim(msg_text)
    This would eliminate the copying of the clob that is currently occurring and may help your space issue.
    Is trim really needed?
    I'm not familiar with any CLOB related bugs in 9i but the above is just some things I would try or question.

  • Exchange 2013 - The Microsoft Exchange Transport service is rejecting message submissions because the service continues to consume more memory than the configured threshold

    Noticed at about noon that no emails had been received all day. Began to investigate and found that the MS Exchange Transport service had been set to deny email submission because it was using too much memory on the server (91%). 
    The error message makes me think that we may have been getting used by malware or something similar.“The Microsoft Exchange Transport service is rejecting message submissions because the service continues to consume more memory than the
    configured threshold.” 
    There are also several warning messages that list particular IP addresses and say that a connection from that IP was denied because there were already the maximum number of connections (20). 
    From what I can tell, all of the IP addresses are from Taiwan. 
    The time period for which some emails may be missing is from close of business yesterday ( 4/3/2014) through about 12:45 today (4/4/2014). 
    From the time I spent reading and trying to figure out the error, I think we may need to readjust our throttling policies to prevent this from happening. 
    The exchange server is currently running at 90%+ CPU and 50%+ memory usage the majority of the time, and I’m not sure how to fix it.
    Also, I cannot get into EMS I get a access denied message from the destination computer. (Exchange server) I want to get into there to change the throttling policy back to default, since we disabled it.
    The Error reads:
    The WinRM client cannot process the request. The WinRM client tried to use Kerberos authentication mechanism, but the destination computer <Exchange> returned an 'access denied' error. Change the configuration to allow Kerberos authentication
    mechanism to be used or specify one of the authentication mechanism supported by the server. (How do I do this?) To use Kerberos, specify the local computer name as the remote destination. (I'm trying to use EMS while logged into the local Exchange server)
    Also verify that the client computer and the destination computer are joined to a domain. (Exchange is on our domain, and the computer trying to connect is the same computer) To use basic, specify the local computer name as the remote destination, specify
    Basic authentication and provide user mane and password. Possible authentication mechanisms reported by server.

    I assumed control of this exchange system already in place and I do not have much experience with exchange 2013 or server 2012. I do know 2008, but that doesn't help very much in this situation.
    Recent changes to the system:
    About three days ago we switch our sessions policy to allow many more connections, and I believe this caused the issue. This is what I changed it to:
    Made the registry DWORD (32-bit) "Maximum Allowed Sessions Per User" and modified the value to 1000. Location of registry change @ HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
    I just changed it to 10 from the 1000. I'm hoping this solves this. So far no.
    Also, I am not the best in the shell or command line interfaces. Any help would be wonderful!

    Hi,
    Yes, could be hardware performance issue. Try recycle the Transport process and see if the issue persists.
    Thanks,

  • Frame.setVisible(true) taking a LONG time

    In displaying a Frame composed of 500 or so Labels,
    setVisible(true) call is taking 20-30 SECONDS to display the Frame.
    This happens on both XP and Suse/Linux.
    With the MSVM, it only takes about ONE second.
    Any theories or suggestions would be greatly appreciated !
    Thanks,
    Mark

    As for me, it takes about 7 seconds.
    3 seconds are for creation of the control peers (an explicit addNotify() call, what is not recomended)
    3 seconds are for the layout (a pack() call).
    I guess your delays are either due to a complicated layout, or due to drastic increase in memory usage, that results in garbage collection been invoked.
    Here is my test program

  • Query is allocating too large memory error in OBIEE 11g

    Hi ,
    We have one pivot table(A) in our dashboard displaying , revenue against a Entity Hierarchy (i.e we have 8 levels under the hierarchy) And we have another pivot table (B) displaying revenue against a customer hierarchy (3 levels under it) .
    Both tables running fine under our OBIEE 11.1.1.6 environment (windows) .
    After deploying the same code (RPD&catalog) in a unix OBIEE 11.1.1.6 server , its throwing the below error ,while populating Pivot table A :

  • Query is allocating too large memory

    I’m building an Analysis in OBIEE against an ASO cube and am seeing the following error:
    Query is allocating too large memory ( > 4GB) and cannot be executed. Query allocation exceeds allocation limits
    The report we’re trying to build is intended to show information from eight dimensions. However, when I try to add just a few of the dimensions we get the “Query is allocating too large memory” error. Even if I filter down the information so that I only have 1 or 2 rows in the Analysis I get the error. It seems like there is something wrong that is causing our queries to become so bloated. We're using OBIEE 11.1.1.6.0.
    Any help would be appreciated.

    This sounds like a known Bug 13331507 : RFA - DEBUGGING 'QUERY IS ALLOCATING TOO LARGE MEMORY ( > 4GB)' FROM ESSBASE.
    Cause:
    A filter has been added in several lines in the 'Data Filters' Tab of the 'Users Permissions' Screen in the Administration Tool (click on Manage and then Identity menu items). This caused the MDX Filter statement to be added several times to the MDX issues to the underlying Database, which in turn caused too much memory to be used in processing the request.
    Refer to Doc ID: 1389873.1 for more information on My Oracle Support.

  • Query is allocating too large memory Error ( 4GB) in Essbase 11.1.2

    Hi All,
    Currently we are preparing dashboards in OBIEE from the Hyperion Essbase ASO (11.1.2) Cubes.When are trying to retrieve data with more attributes we are facing the below error
    "Odbc driver returned an error (SQLExecDirectW).

  • I have a problem with setVisible(true) !!!!!!

    Hi!
    Could you tell me please, how can I use the method
    getSize() before call the method setVisible(true)??
    If I call the method getSize() before setVisible(true)
    then return getSize() only 0 !!!!!
    I must call getSize() before setVisible(true).
    Thank you for your help ;-))
    Code:
    import java.awt.*;
    class Test extends Frame
    Test()
    t.setSize(200, 100);
    Button b=new Button("test");
    t.add(b);
    System.out.println("Size: "+ b.getSize()); //It doesn't work!!!!
    t.setVisible(true); // ohne das haut's ihn raus !
    public static void main(String args[])
    (new Test());
    }

    If you want to get the Button size, then you should set the button size before you called getSize(), otherwise you will get the value of zero just like yours.
    Try the following code.
    import java.awt.*;
    class Test extends Frame
    Test()
    setSize(200, 100);
    Button b=new Button("test");
    b.setSize(70,25);
    add(b);
    System.out.println("Size: "+ b.getSize()); //It doesn't work!!!!
    setVisible(true); // ohne das haut's ihn raus !
    public static void main(String args[])
    new Test();
    In this way, you will get the button size!

  • Displaying English characters on a Japanese locale

    The application I am working is localized for Enlish and Japanese. I need to bring up the application in English on a Japanese locale ( OS ). I tried to use the command line parameters -DLocale.language en -DLocale.country US. Even then, I am not able to bring the application up in English, I comes up in Japanese.Is there some way to bring the app in English on a Japanese locale(OS)?
    I have also read about editing the font.properties file, Does somebody what needs to be added to render the app in English?
    Thanks,

    If you are using a Windows box, try the command
    CHCP 437
    which will change your OS locale to USA, and the command
    CHCP 932
    will revert the OS locale to Japan. It must be better first entering the simple command
    CHCP
    and confirm the current codepage of the OS.
    (Note that this reply is concerned with the OS property, not about Java.)

  • Differences between regular and Japanese localized

    What are the differences between regular JDeveloper 2.0 and
    Japanese localized versions ?
    I received regular JDeveloper 2.0 (Build 343) from the U.S.
    Is there any issue or limitation to use it in order to use
    Oracld RDBMS 8.0.5 & 8.1.5 created with character set JA16EUC
    running on Solaris ?
    I think there is no issue or limitation if we use it with
    NLS-zip.
    Or do we have to use Japanese localized versions ?
    Then what's the benefit of using it ?
    Any information about this would be much appreciated.
    Best regards,
    null

    The US JDeveloper version if used with Japanese fonts , or
    better with a Japanese NT will allow for display and input of
    Japanese text including when interacting with Oracle databases.
    This is the internationalization support and JDeveloper is
    internationalized for Japanese
    The only difference between the versions (other than a couple OS
    dependent bugs in the readme file) is that the Japanese version
    has a UI and documentation in Japanese as opposed to English.
    Hope this helps.

    Can anyone suggest why Oracle consumes 100% Memory? and how do we resolve this?.
    Regards,
    Sabdar Syed.

    Many Unix tools add to each dedicated server process memory the SGA size because under Unix each dedicated server is attaching the SGA shared memory segment to its process address space: so these Unix tools are not so reliable for Oracle.
    To check the Oracle memory usage, it is generally more recommendded to use the V$ views such as V$SGASTAT and V$PGASTAT.

  • Can I use "\" to input "¥" symbol under Japanese locale?

    Hi, I'm a Mac developer and I want to know the standard behavior for Mac when press "\" key under Japanese locale. Should Mac display "\" or "¥" symbol? I notice that Windows will show "¥", but many Mac applications just show "\", so I want to make clear is this is Mac's standard behavior.
    Another question is, how can I input "¥" under Japanese locale? Is "Opt+Y" the only choice I can choose?

    do you mean that binding a key to which character is just defined by the keyboard layout/input method? For example, if I input "\" through Kotoeri Hiragana input, it's that input's thing to decide what should output?
    Yes. The result of pressing a key with a particular symbol printed on it is determined by the .keylayout file or input method which is active at the time. Using the US physical keyboard with the input set to Kotoeri Hiragana, pressing the key marked \ produces へ　in direct Kana mode or \　in the normal mode.

  • Internet explorer consuming huge memory when OBIEE reports Run

    Hi all,
    I am running OBIEE report. But when reports run for displaying results, then Internet Explorer consumes huge memory( can view in Task Manager) and so all other application becomes very slow and dont work. I am using XP operating system and 1 GB Ram. OBIEE is installed at Server and i am running report at other system by accessing URL of the server.
    Please tell me the solution so that Internet Explorer does not consume huge memory.

  • No Japanese locale on a machine with Japanese OS

    I am running a small test application on a Windows box with a Japanese version of XP running on it. The default locale correctly displays as Japanese (Locale.getDefault()). However, when I say Locale.getAvailableLocales() and display the results in a combo box, Japanese is not one of the available locales.
    In addition, when I try to format a date, with something like:
    Calendar c.setTime(new Date(System.currentTimeMillis()));
    DateFormat df = DateFormat.getDateTimeInstance(DateFormat.DEFAULT, DateFormat.DEFAULT, Locale.getDefault());
    String str += df.format(c.getTime());
    the date is still in English.
    How is it possible to be running on a Japanese OS and not have Japanese be one of the available locales in Java?
    Thanks very much.

The JRE installer by default installs a European languages version if it recognizes that the host operating system only supports European languages. If the installer recognizes that any other language is needed, or if the user requests support for non-European languages in a customized installation, a complete international version is installed. "
    and
    "The European languages version of the J2SE Runtime Environment 5.0 supports all locales for the following languages: Albanian, Belorussian, Bulgarian, Catalan, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Icelandic, Italian, Latvian, Lithuanian, Macedonian, Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Slovenian, Spanish, Swedish, Turkish, Ukrainian."
    You might have the European languages version if you didn't use a default method of installing it on that Japanese system (which should have given you the full international version).
