Retrieve Heap size from program
Hi, i searched the foruns with "get heap size" and "retrieve size"
and i also checked the System.getProperty(String key) string keys at
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#getProperty(java.lang.String)
and havent found a method to retrieve the currently set heap size.
Is there a way to do this?
My program needs to initialize something based on how large the
user set the heap size (using the command line -Xms32m -Xmx128m...)
Any info would be appreciated! Thanks alot!
Touche!
Thanks alot you pointed me in exactly the right direction.
When i did research on java.lang.Runtime
i found this post

Hi,
Does anybody know here how to specify the Heap size with JAR.
From command line, I type java -jar -ms128M -mx350M IzoneIDE.jar
My jar file is executable, so how can I specify the heap size in Jar Files.
Please dont comment this as a Cross Post as I dont find any answer in Java Programming forum, thats why I post it here.
Thanks
RaheelCheck here, http://java.sun.com/docs/books/tutorial/jar/
not sure if the right info is there, but If you do find it pls let us know.

Hi all,

Oracle Forms & Reports Service 10.1.2.3.0
Oracle Database 10.2.0.1.0
JDK 1.5
Jinitiator 1.3.1.30
Apache POI 3.5
From forms we are writing to excel files after copying XL template using Apache POI 3.5 and JDK 1.5. This XL template file has got lot of macros.
We have imported the Java class files into form as pl/sql library. We are able to write upto 7Mb size of XL file. Beyond that size it comes with the error Ora-105101.
We tried to increase the JVM Heap Size to 640M by setting values -Xmx640M everywhere in OC4J_BI_FORMS/Server Properties/Java Options, Home/Server Properties/Java Options through Enterprise Manager console. Also manually set the values in OPMN.XML and reloaded the same. Also set -Xmx640M in Jinitiator 1.3.1.30 Java Runtime Parameters. Also set in Java console. All settings have no effect.
We have written a small program to display the run time memory from forms, which displays only maximum memory 63M all the time.

When the size of XL is more than 7Mb, after message(0) it will be display oracle error.
From command prompt if we run the same java class file by passing -Xmx256m parameter we are able to write to big XL file.
Can anyone tell me where I am wrong... Can we increase the JVM Heap Size from forms...I have a simular problem.
Via Forms I call a Java class (import Java class -> PL/SQL class java method).
For this specific process I need to set the Xmx java option...
How do I do this ?
Changing the java option for the Forms-OC4J in the EM doesn't help.
Is there an other level where I can modify this ?
Does the java process of the forms is the single process that exists ? How does he handles such java calls?
Are that separed java processes ? threads ? ....
Thanks !!! -

Hello
i was playing around with websphere and increased the heap size from 3072 to 5072. Now when i tried to restart the server...it wont come back up. I cant getinto the Websphere administrative console either. does any one know a way to set the heap size thru command line back to 3072 for this server?

Modifying heap size allocated to glassfish...
Hello!
I've noticed that by default glassfish uses 512Mb for the heap. I'd like to modify this value.
How can I change it?
Is there any way through the administrative consiole provided (asadmin)?
Thank you
SorinYou can modify the heap size from the admin console.
Login to the admin console, Click on Application Server on the Left Pane.
On the Right Pane, click on JVM Settings -> JVM Options.
Modify -Xmx to whatever value you desire.
Cheers,
Vasanth -
Configure heap size without -Xmx
Is it possible to configure java to always start with 512M head size without use the -Xmx option. In other words, can I change the default heap size from 64M to 512M or do I have to always start my java with -Xmx512M?
Hi,
Are you really asking whether you can change the maximum heap size, programmatically, from within the JVM? If you do, the answer is that you cannot do that. The JVM needs to pre-allocate a few memory spaces (generations, card table, etc.) while it's starting up and, once it's up and running and starts executing bytecodes, at least some of those memory spaces cannot be resized.

Massive memory hemorrhage; heap size to go from about 64mb, to 1.3gb usage
**[SOLVED]**
Note: I posted this on stackoverflow as well, but a solution was not found.
Here's the problem:
[1] http://i.stack.imgur.com/sqqtS.png
As you can see, the memory usage balloons out of control! I've had to add arguments to the JVM to increase the heapsize just to avoid out of memory errors while I figure out what's going on. Not good!
##Basic Application Summary (for context)
This application is (eventually) going to be used for basic on screen CV and template matching type things for automation purposes. I want to achieve as high of a frame rate as possible for watching the screen, and handle all of the processing via a series of separate consumer threads.
I quickly found out that the stock Robot class is really terrible speed wise, so I opened up the source, took out all of the duplicated effort and wasted overhead, and rebuilt it as my own class called FastRobot.
##The Class' Code:
public class FastRobot {
private Rectangle screenRect;
private GraphicsDevice screen;
private final Toolkit toolkit;
private final Robot elRoboto;
private final RobotPeer peer;
private final Point gdloc;
private final DirectColorModel screenCapCM;
private final int[] bandmasks;
public FastRobot() throws HeadlessException, AWTException {
this.screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
this.screen = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
toolkit = Toolkit.getDefaultToolkit();
elRoboto = new Robot();
peer = ((ComponentFactory)toolkit).createRobot(elRoboto, screen);
gdloc = screen.getDefaultConfiguration().getBounds().getLocation();
this.screenRect.translate(gdloc.x, gdloc.y);
screenCapCM = new DirectColorModel(24,
/* red mask */ 0x00FF0000,
/* green mask */ 0x0000FF00,
/* blue mask */ 0x000000FF);
bandmasks = new int[3];
bandmasks[0] = screenCapCM.getRedMask();
bandmasks[1] = screenCapCM.getGreenMask();
bandmasks[2] = screenCapCM.getBlueMask();
Toolkit.getDefaultToolkit().sync();
public void autoResetGraphicsEnv() {
this.screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
this.screen = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
public void manuallySetGraphicsEnv(Rectangle screenRect, GraphicsDevice screen) {
this.screenRect = screenRect;
this.screen = screen;
public BufferedImage createBufferedScreenCapture(int pixels[]) throws HeadlessException, AWTException {
// BufferedImage image;
DataBufferInt buffer;
WritableRaster raster;
pixels = peer.getRGBPixels(screenRect);
buffer = new DataBufferInt(pixels, pixels.length);
raster = Raster.createPackedRaster(buffer, screenRect.width, screenRect.height, screenRect.width, bandmasks, null);
return new BufferedImage(screenCapCM, raster, false, null);
public int[] createArrayScreenCapture() throws HeadlessException, AWTException {
return peer.getRGBPixels(screenRect);
public WritableRaster createRasterScreenCapture(int pixels[]) throws HeadlessException, AWTException {
// BufferedImage image;
DataBufferInt buffer;
WritableRaster raster;
pixels = peer.getRGBPixels(screenRect);
buffer = new DataBufferInt(pixels, pixels.length);
raster = Raster.createPackedRaster(buffer, screenRect.width, screenRect.height, screenRect.width, bandmasks, null);
// SunWritableRaster.makeTrackable(buffer);
return raster;
}In essence, all I've changed from the original is moving many of the allocations from function bodies, and set them as attributes of the class so they're not called every time. Doing this actually had a significant affect on frame rate. Even on my severely under powered laptop, it went from ~4 fps with the stock Robot class, to ~30fps with my FastRobot class.
##First Test:
When I started outofmemory errors in my main program, I set up this very simple test to keep an eye on the FastRobot. Note: this is the code which produced the heap profile above.
public class TestFBot {
public static void main(String[] args) {
try {
FastRobot fbot = new FastRobot();
double startTime = System.currentTimeMillis();
for (int i=0; i < 1000; i++)
fbot.createArrayScreenCapture();
System.out.println("Time taken: " + (System.currentTimeMillis() - startTime)/1000.);
} catch (AWTException e) {
e.printStackTrace();
}##Examined:
It doesn't do this every time, which is really strange (and frustrating!). In fact, it rarely does it at all with the above code. However, the memory issue becomes easily reproducible if I have multiple for loops back to back.
#Test 2
public class TestFBot {
public static void main(String[] args) {
try {
FastRobot fbot = new FastRobot();
double startTime = System.currentTimeMillis();
for (int i=0; i < 1000; i++)
fbot.createArrayScreenCapture();
System.out.println("Time taken: " + (System.currentTimeMillis() - startTime)/1000.);
startTime = System.currentTimeMillis();
for (int i=0; i < 500; i++)
fbot.createArrayScreenCapture();
System.out.println("Time taken: " + (System.currentTimeMillis() - startTime)/1000.);
startTime = System.currentTimeMillis();
for (int i=0; i < 200; i++)
fbot.createArrayScreenCapture();
System.out.println("Time taken: " + (System.currentTimeMillis() - startTime)/1000.);
startTime = System.currentTimeMillis();
for (int i=0; i < 1500; i++)
fbot.createArrayScreenCapture();
System.out.println("Time taken: " + (System.currentTimeMillis() - startTime)/1000.);
} catch (AWTException e) {
e.printStackTrace();
}##Examined
The out of control heap is now reproducible I'd say about 80% of the time. I've looked all though the profiler, and the thing of most note (I think) is that the garbage collector seemingly stops right as the fourth and final loop begins.
The output form the above code gave the following times:
Time taken: 24.282 //Loop1
Time taken: 11.294 //Loop2
Time taken: 7.1 //Loop3
Time taken: 70.739 //Loop4
Now, if you sum the first three loops, it adds up to 42.676, which suspiciously corresponds to the exact time that the garbage collector stops, and the memory spikes.
[2] http://i.stack.imgur.com/fSTOs.png
Now, this is my first rodeo with profiling, not to mention the first time I've ever even thought about garbage collection -- it was always something that just kind of worked magically in the background -- so, I'm unsure what, if anything, I've found out.
##Additional Profile Information
[3] http://i.stack.imgur.com/ENocy.png
Augusto suggested looking at the memory profile. There are 1500+ `int[]` that are listed as "unreachable, but not yet collected." These are surely the `int[]` arrays that the `peer.getRGBPixels()` creates, but for some reason they're not being destroyed. This additional info, unfortunately, only adds to my confusion, as I'm not sure why the GC wouldn't be collecting them
##Profile using small heap argument -Xmx256m:
At irreputable and Hot Licks suggestion I set the max heap size to something significantly smaller. While this does prevent it from making the 1gb jump in memory usage, it still doesn't explain why the program is ballooning to its max heap size upon entering the 4th iteration.
[4] http://i.stack.imgur.com/bR3NP.png
As you can see, the exact issue still exists, it's just been made smaller. ;) The issue with this solution is that the program, for some reason, is still eating through all of the memory it can -- there is also a marked change in fps performance from the first the iterations, which consume very little memory, and the final iteration, which consumes as much memory as it can.
The question remains why is it ballooning at all?
##Results after hitting "Force Garbage Collection" button:
At jtahlborn's suggestion, I hit the Force Garbage Collection button. It worked beautifully. It goes from 1gb of memory usage, down to the basline of 60mb or so.
[5] http://i.stack.imgur.com/x4282.png
So, this seems to be the cure. The question now is, how do I pro grammatically force the GC to do this?
##Results after adding local Peer to function's scope:
At David Waters suggestion, I modified the `createArrayCapture()` function so that it holds a local `Peer` object.
Unfortunately no change in the memory usage pattern.
[6] http://i.stack.imgur.com/Ky5vb.png
Still gets huge on the 3rd or 4th iteration.
#Memory Pool Analysis:
###ScreenShots from the different memory pools
##All pools:
[7] http://i.stack.imgur.com/nXXeo.png
##Eden Pool:
[8] http://i.stack.imgur.com/R4ZHG.png
##Old Gen:
[9] http://i.stack.imgur.com/gmfe2.png
Just about all of the memory usage seems to fall in this pool.
Note: PS Survivor Space had (apparently) 0 usage
##I'm left with several questions:
(a) does the Garbage Profiler graph mean what I think it means? Or am I confusing correlation with causation? As I said, I'm in an unknown area with these issues.
(b) If it is the garbage collector... what do I do about it..? Why is it stopping altogether, and then running at a reduced rate for the remainder of the program?
(c) How do I fix this?
Does anyone have any idea what's going on here?

Turns out this issue was directly related to the garbage collector. The default one, for whatever reason, would get behind on its collection at points, and thus the memory would balloon out of control, which then, once allocated, became the new normal for the GC to operate at.
Manually setting the GC to ConcurrentMarkSweep solved this issue completely. After numerous tests, I have been unable to reproduce the memory issue. The garbage collector does an excellent job of keeping on top of these minor collections. -
How to retrieve the values from a LinkedList
Hello,
I have just put this question in java programming forums by mistake...I think that it should be here ...
I have created a LinkedList to store the results of a query to a database.
These reasults are decimal numbers and then I want to sum all these numbers to be able to make the average.
But when I try to retrieve the values of the Linked List I always receive an incopatible types error..
Here is an extract of my code in a jsp page.
LinkedList Average = new LinkedList();
String Media = rst.getString(10);
Average.add(Media);
int Size = Average.size();
double Sum = 0.0;
for (int i=0; i<=Size; i++)
double Result = Average.get(i)
Sum = Sum + Result;
}If I try to retrieve the value of only one node from the list , I can just putting <%=Average.get(i)%>...but..how can I retrieve all the values (they are decimal numbers) to be able to add them?If you want to sum all the values, is there any reason you just don't retrieve the sum from the database rather than the list of values?
anyway
List average = new LinkedList();
while (rst.next()){
// retrieve the number:
String mediaString = rst.getString(10);
Double media = Double.valueOf(mediaString);
// or maybe like this if it is a number in the database
Double media = new Double(rst.getDouble(10));
average.add(media);
doubleSum = 0.0;
for (Iterator it = average.iterator(); it.hasNext(); ){
Double result= (Double) it.next();
doubleSum += result.doubleValue();

harshalToo much code. It's also not well intented nor formatted. I don't see a question either or it got lost in that heap of unformatted code.
I will only answer the question in the thread's subject:

Any way to retrieve this image from my cache? When saved it only saves as a 1.7KB blank file.
I'm trying to retrieve an image from Firefox's cache but so far have had no luck in doing so. The picture was hosted on imageshack and I had it open in a window but when I refreshed the page several hours later it was gone. I refreshed the page several more times, tried messing with the url to see if that did anything, but no luck. I haven't cleared anything on Firefox so I'm hoping there's some way I can recover it from the cache.
I followed the instructions on this page: http://groups.google.com/group/mozilla.support.firefox/msg/73bab3fb55ac5b42
However, when I right clicked the URL and chose "Save Link As..." it only saved a 1.7KB file that none of my photo editing programs can recognize or open. I've tried going to cache entries for other image links and saving them and when I choose Save Link As for those they save just fine, and in full size, so I'm not sure why this one won't work...I'm using Offline Mode so I'm not sure why the picture no longer being hosted online should make a difference one way or the other. I'm just hoping that my act of refreshing the page and nothing being there didn't overwrite the cache file and thus erase the cache'd image.
So is there any hope of retrieving this picture or is it gone for good?Hi.
Once the image in question is replace with another one, the old one is erased. That is to say, if you open an image, say www.domain.com/image.png, and it's a 200x200 image, then you close it, it's still on cache, and you can access it through the cache. But if the image is changed in the server, that same exact url, and you access it again, at you see a 250x200 image (just an example), then the 200x200 is gone forever.
Your hope is that you never accessed the same URL again, so the old cache wasn't erased. If you know the url of the image, simply select offline mode (File > Work Offline, I think) and access its url. It will load the cached version and not check for the online one. Only if there is a cached version, of course.
I hope this helps. -
REP-0002: Unable to retrieve a string from the Report Builder message file;
Hi,
I've a custom report in which i need to display a large string, of more than 4000 characters. To cater to this requirement i've written a formula column which displays string upto 4k characters and for a string of size beyond 4k i am calling a procedure which uses a temp table having a clob field.
For a small string the report runs fine but whenever a large string requirement comes into the picture, said procedure gets triggered and i get REP-0002: Unable to retrieve a string from the Report Builder message file.
OPP log for the same gives an output as under:
Output type: PDF

Report Builder 10g
BI Publisher's version : 4.5.0
RDBMS Version : 10.2.0.4.0
Oracle Applications Version : 12.0.6
Searched for the same on metalink and found Article ID 862644.1, other than applying patch and upgrading version of BI Publisher is there any other workaround to display a comma seperated string as long as 60k characters, If any please suggest.
Thanks,

Problem Description
When running a *.REP generated report file you get errors:
REP-00002 Unable to retrieve string from message file
REP-01439 Cannot compile program since this is a runtime report
Running the same report using the *.RDF file is successful.
You are running the report with a stored procedure,
OR you are running against an Oracle instance other than the one developed on,
Or, you recently upgraded your Oracle Server.
Solution Description
1) Check that the user running the report has execute permissions on any stored
SQL procedures called. <Note:1049458.6>
2) Run the report as an .RDF not an .REP , that is remove or rename the .REP
version of the report. <Note:1012546.7>
3) Compile the report against the same instance it is being run against.

hi,
I need to set the maximum heap size of the JVM. I know that I can do
it for a single run by saying:
java -Xmx75M example.class
But how do I make the JVM use this maximum heap size for all its
runs, without specifying '-Xmx75M' in every run.
I need this because I am using my system as a server for JSP web
site. For that site if a very simple query is given such as 'a' in title, as many as 6000
records as retrieved from my Filemaker Databases and the java
ResultSet object is not able to handle those records. The system is
then throwing an exception and error message 'Host not found' is
sent back to the client's browser. As far as I know, Filemaker does
not support 'LIMIT' keyword in queries.
So please tell me how can I rectify that problem.
Thanks in advance,
niranjan maturihi,
I tried setting TOMCAT_OPTS. The maximum I could go in my system is 1300M
i.e. set TOMCAT_OPTS="-DXmx=1300m".
Still I am having the problem that when some 5000 records are fetched from the database, the ResultSet object is not able to handle them. It is able to handle upto 2000 records. I am using windows2000, jdk1.3.2 and Filemaker Pro 5.0 databases.
I tried to set the maximum number of records that can be retrieved to 2000 so that the problem will be solved. But I am not able to set that as well. I did:
Class.forName("com.fmi.jdbc.JdbcDriver").newInstance();
Connection con = DriverManager.getConnection("standard statement");
PreparedStatement pstmt = con.prepareStatement("select id, pubyear, Checkedoutby, >>callnumber from mprrc_materials");
pstmt.setFetchSize(2000);
ResultSet rs3 = pstmt.executeQuery();Its giving the error:
java.lang.AbstractMethodError at that setFetchSize() statement.
I guess the JDBC driver provided by Filemaker Pro does not support that. So what can be done to solve the problem.
Thanks,
Niranjan Maturi -
How to increase heap size in OC4J .
Hi Friends ,
I am getting out of memory exception,so i need to increase the heap size , so kindly provide me the information where and how could I increase the heap size in OC4J ?.
Yrs
Jeyaprakashyou 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 -
I'm trying to write a program using NetBeans and I keep getting OutOfMemoryErrors. I have 2GB of RAM and I've attempted to modify the netbeans.conf file to increase the heap size at startup. The changes I've made aren't being reflected in the memory manager tool (it still indicates a maximum size of ~50MB). The pertinent code from the config file is as follows:
netbeans_default_options="-J-Xms512m -J-Xmx1024m -J-XX:PermSize=128m -J-XX:MaxPermSize=512m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true -J-XX:NewSize256m"
Assuming my memory usage won't exceed these limits, any suggestions as to how to make sure the changes are being implemented?I would subscribe to the netbeans user mail list, and pose your question to that list. The Sun Netbeans gurus live there.
I would also use a seperate email account to subscribe to the list as it generates alot of messages daily. If thats not an option, definatly try to set up a rule that seperates messages from the list from your regular email.
The main netbeans top level mail list web page is here with all the instructions to subscribe and unsubscribe.
Good luck,
JJ
