Heap space out of memory in weblogic

Hi,
I am using weblogic server 10.3.2,Actually i am facing heap space error because lot of data is there is the database approx 50lacs Data.
And my system configuration is 8GB RAM and 64bit machine.
but after 5 minutes heap space error...
Note:I have already configured in the setDomainEnv.cmd File
if "%JAVA_VENDOR%"=="Sun" (
set WLS_MEM_ARGS_64BIT=-Xms256m -Xmx2048m
set WLS_MEM_ARGS_32BIT=-Xms256m -Xmx512m
) else (
set WLS_MEM_ARGS_64BIT=-Xms512m -Xmx2048m
set WLS_MEM_ARGS_32BIT=-Xms512m -Xmx512m
set MEM_PERM_SIZE_64BIT=-XX:PermSize=256m
when i start the weblogic server ,below is the details but i have already changed then why

Game Heap Space - Out Of Memory Error

Hi there,
Ive completed my pacman/space invaders hybrid game- which has a main game and two playable videos. Its all fine, but when I go to run it it says;
Exception in thread "Image Fetcher 1" java.lang.OutOfMemoryError: Java heap space
Exception in thread "Image Fetcher 2" java.lang.OutOfMemoryError: Java heap space
Ive come to realise that this error is from the amount of data used to make up the game/video with there being around 150 images for the videos. Ive temporarily corrected this problem by making each video 26 images long (2.6secs each) but to get the full experience the user need to see around 75images.
After a bit of research I found that i needed to increase my 'heap space'- and I attempted to do this thru cmd, attemptin to increase it to 512mb.
The problem is the game doesnt have a main, or at least not one that I nor the computer can locate. And to get the heap space to increase it needs a main?!
I honestly dont know what I am doing here- but could anyone tell me how I can increase my heap space or locate a main? Im really confused!
Any help appreciated

Thats the whole code for the applet- preloadin the image (and also everything that doesnt relate to this problem lol). Ive asked around and the answer I was given I wasnt satisfied with- make the files smaller/delete some- the files are already at their smallest about 10kb each. And also apparently (I didnt know this...) but due to security restirictions I wouldnt be able to increase the heap size anyway (this is to run the applet on my own... and others computers).
So Im really too sure what to do at the minute. Anymore help would be appreciated though.
Thank you!

Once you get to the state where you're out of memory, you'll get any number of possible variations on the error message. These variations will give you absolutely zero help for why you've run out of memory. Without more information, it's impossible to tell whether you have a memory leak, or whether you simply have too small a value for "maxmem" in the JVM.
Typically, I would assume that if the server has been running for a "while" (whatever that means) without error, then it probably isn't a simple issue with setting the "maxmem" value high enough. If it does fail pretty quickly after startup (and processing of initial messages), then it very well could be a maxmem problem. This is done by adding or changing the "-Xmxnnn" command-line parameter to the JVM. For instance, if you wanted to give it 2g of max heap, you would put "-Xmx2048m" on the command line. That value won't work on Windows (not sure about Vista or 64-bit), but it will work perfectly well on Unix/Linux.
If you have a memory leak, it's good to first verify this by sitting on the "Server"->"Performance" page in the WebLogic console. If you watch the "memory free" (or "memory inuse") percentage, you'll see that it varies by a wide margin over time. What you want to do is to be able to force a GC (there should still be a button there to do that) and then note the percent free immediately after that. You should do this every few minutes while the server is actively working. If the percent free value (after the GC) is consistently going down, even slowly, then you likely have a memory leak. This is where it gets a little more difficult. You could look at the free VisualVM tool which provides some memory debugging features, but they are somewhat limited (I only know this from reading some literature, I haven't tried it), or you could look at the commercial tools JProfiler, JProbe, or YourKit (in decreasing order of my personal preference).

Hi, I have been having the same problem for about 2weeks, keep deleting the app and reinstalling but this does not help. I even deleted it from Facebook as that's where u play thru, but that doesn't help either!!!!!! Its driving me mad. Any luck and I'll let u know

Java Heap Space Issues

Greetings. I hope this is the right forum
I have a project, a chess program, that makes use of some very large static arrays. As I experiment with increasing the size of the arrays, I eventually run into heap space out of memory errors when instantiating these arrays.
My research has suggested various ways of adjusting the amount of memory available to the Java Runtime Environment. I am pretty sure I can deal with that.
My comment is that there does not appear to be a way to deal with this programmatically, from within my program. I'd like to make my program available on the web in applet form. If I do so it appears that I have to either limit the size of my arrays, or else instruct any potential user to adjust JVM settings themselves, outside of my program. Do I have this right?
Thanks.

ok I know nothing about jnlp but this looks promising. The following quote from that page suggests to me a way to package my program, with a minimum of modification, so that resources are allocated to the JVM before the application is loaded. The point being that the end user doesn't need to manually adjust the settings. Thanks, I'll give it a try.
By default, jar and nativelib resources will be downloaded eagerly, i.e., they are downloaded and available locally to the JVM running the application before the application is launched. The jar and nativelib elements also allow a resource to be specified as lazy. This means the resource does not have to be downloaded onto the client system before the application is launched.

Out of memory error for large recordings:

Hi,
My workflow process takes input as a list. It loops through the workflow for all the items in the list. If my list contain 4 items, there will be 3*7= 21 steps when I invoke the process. I can able to check my recordings for debugging.
If I give 5 inputs, It takes around 5*7 = 35 steps in the workflow. If I try to play the recording, i see the error: java heap space: Out of memory exception. I changed my space to Xmx1024m in workbench.ini. I also did: java -Xms<initial heap size> -Xmx<maximum heap size> (Q1: do we need to restart the JBoss after we do the second step? ).
Q2: My system is Windows7 with 4GB RAM. I have liveCycle 8.2 with SP2. JBoss & MySql. Do I need to set this java RAM size in any of our JBoss server files?
Q3: Is there any file to set the maximum permissible steps for a process recording? If so, please let me know. It would be a great help.
Thanks,
Chaitanya

If the size of the documents you are adding as input are very large this could result in OOM errors so that is something to consider.
Some other things to try are as follows:
1. Increase memory allocated by JBoss by another 200 - 300 M as per the following documentation on the web:
http://help.adobe.com/en_US/livecycle/9.0/workbenchHelp/help.html?topic=000097&topic=00183 7
2. Read the following sections of the Workbench Help which can be found on the web and describes how to limit your recording storage space used: http://help.adobe.com/en_US/livecycle/9.0/workbenchHelp/help.html?topic=000097&topic=00106 0
I would suggest increasing your maxNumberOfRecordingEntries to about 200.

Out of memory: Java heap space

Hello,
I am working on a project, that simulates large populations, with each individual being a separate Objecta(a couple of kilobytes in size each).
Once i reach a bug enough number of those Objects (stored in a Vector), i get Out of memory: Java heap space exception.
Am i having a memory leak in Java? Or am i really reaching the maximal JVM limit and i need to reconfigure it, to support larger heap size?
:)

Am i having a memory leak in Java?Because of garbage collection there, by far and large, aren't memory leaks in java. However, there certainly is memory waste.
If each of these objects you make room for are unnecessarily laden with references to other large objects creating huge networks of objects that never free their memory, and then you allocate 1 million of them, then, while not a leak, you are wasting your memory space.
Look through your class and inspect each field to see if any of them could be holding more data than you intend. If so, multiply the amount of that data by 1,000,000 or however many objects you are going to instantiate to determine if this produces and absurd amount of memory. You should be able to predict ~how much storage your data will need...each char is 2bytes, each int is 4 bytes, doubles are 8 etc

I think this can't be issue with following variables:As I hv set them from 64m to 256, still issue coming.
WLS_MEM_ARGS_32BIT=-Xms200m -Xmx256m
MEM_PERM_SIZE_32BIT=-XX:PermSize=200m
MEM_MAX_PERM_SIZE_32BIT=-XX:MaxPermSize=256m
Any suggestion.
Thanks,
Nitin.

making it 512 temporarily working fine, but my concern was something must have been eating all the memory.
I did run bcc with 128 MB and deployed lots of initial data too, didn't face the issue in recent past with same versions and same build size.
ATG:10.2
Weblogic: 10.3.5
JDK:1.6.0_25
One more info:
my build size is around 200 MB
I m not running productionAgent,But I didn't make that essential while setting agent.
Can that be issue that some Manager trying to hit the server continuously and eating the memory.
Can not running the agent server, eat substantial memory?

Out of HEAP vs. out of NATIVE memory

I'm working on a document to help our support team classify our customers' out-of-memory errors and know whether it is due to HEAP or NATIVE MEMORY. I've pulled some errors we've seen in domain logs from customers and tried to classify them. Can someone tell me if I got these right?
These are the ones I think are out of heap errors:
1) Allocation of … bytes failed for heap
TLA bailout requested
TLA unwind thread links
2) java.lang.OutOfMemoryError
3) Throwing OutOfMemory: nativeGetNewTLA
Throwing OutOfMemory: allocLargeObjectOrArray
These are the ones I think are out of native memory:
4) Throwing OutOfMemory
Unable to equeue element
JRockit aborted: Out of memory (68)
5) JRockit aborted: Out of memory (68)
Failed to acquire native memory. Try reducing Java heap size
I'm not sure if we've seen this one yet after upgrading to WebLogic 10 from WebLogic 8
Thanks,

Hi,
I have some similar problem.
I have have the Maximum heap size set to 4GB, but the total java process takes up to 40GB or 64GB memory. I had this problem in September last year, and it came back yesterday.
I would like to know what in the code of my application can make JRockit behave this way; I get no OutOfMemorError which means that my application does not use too much memory, so what does ??
Any ideas are really welcome :)

Out of heap space erorr

Hi guys,
My app is mainly a wordlist crunching program. Its a swing app.
There are two flat files about 10 MB each. The first part of the app is supposed to read all that data from the two sperate flatfiles and put them into two seperate Hashtables.
The first first file get loaded fine into the Hashtable. But during the loading of the second file, the program crashes giving a "out of Heap space" error.
Is this due to a memory leak? ( But thats not supposed to happen in Java) or the JVM with its default memory allocation cannot support processing such huge flat files?
I dont want to use the -Xmx option cuz thats what I am gonna use as a programmer. But when i deploy the application. nobody is going to use this option to run the program each time.
What do you think guys? How can this be solved?

Hi , all objects in java live on Heap..As objects grow on the heap ,available space on heap will be decreased , In such cases you will get that error..
to solve the problem,unreachable objects needs to be deleted from the heap..
I hope the following can solve yr problem.
1) make null all unuseful object references ( all unused object refrences related to your first file..
obj=null;
2)Call System.gc() method before loading your second file or at end of the first file.
Consider this Example
import java.util.Date;
public class CheckGC {
public static void main(String [] args) {
Runtime rt = Runtime.getRuntime();
System.out.println("Total JVM memory: " + rt.totalMemory());
System.out.println("Before Memory = " + rt.freeMemory());
Date d = null;
for(int i = 0;i<10000;i++) {
d = new Date();
d = null;
System.out.println("After Memory = " + rt.freeMemory());
rt.gc(); // an alternate to System.gc()
System.out.println("After GC Memory = " + rt.freeMemory());
Thanks

Weblogic 6.1 deployment out of memory error - please help

I am getting an out of memory error when deploying an ear to a weblogic 6.1 server. I tried increasing heap size with the startup param. I also tried upgrading the jdk to 1.3.1_02. Here is how I am starting weblogic -
"%JAVA_HOME%\bin\java" -hotspot -XX:MaxPermSize=256m -ms64m -mx64m -classpath "%CLASSPATH%" -Dweblogic.Domain=mydomain -Dweblogic.management.discover=false -Dweblogic.Name=myserver "-Dbea.home=C:\bea" -Dweblogic.management.password=%WLS_PW% -Dweblogic.ProductionModeEnabled=%STARTMODE% "-Djava.security.policy==C:\bea\wlserver6.1/lib/weblogic.policy" weblogic.Server
I tried 64, 128, and 256 for the MaxPermSize param and the larger I make this number, the longer the deploy takes. I also tried lowering the session timeout to 1 min from 30. Now, when I deploy to the weblogic connection, jdev writes the war, then hangs. The rest of my desktop is slow but responsive, but I let jdev go for up to 1hr when running this deploy, and it never even starts the weblogic.deploy call. I end up killing it. This ear is not very big and is a simple servlet.
Any thoughts?

Consequences of out of heap space errors

Hello,
I'm curious what are the consequences of an out of heap space error. If my application is running and I get a heap space error does this corrupt my application? If I had some variable x = 123 can a out of heap space error corrupt x to make it -123?
Thanks

No.
Corrupt is to harsh of a word.
However where you run out of space can make your application unusable. For example you might run out of space when loading a new class. Or when creating a new thread. Does your code account for that? If not then that could be a problem.
On the other hand if you are creating a large data structure and at some point you run out of memory then if you just go back to where you started the creation and remove all references then it shouldn't impact your application.

Weblogic generating out of memory error when commandline run doesn't

Hello,
I am just beginning to use weblogic. I have a jar file which runs fine if run from command line with the options
"C:\Program Files (x86)\Java\jre6\bin\java" -jar -Xms1024m -Xmx1024m Report.jarIt connects to oracle and selects some data around (500k records) and writes it to a csv.
When I run the same jar from within a web application (I mean obvoiusly a servlet calling the jar's main method) the webapp generates
out of memory error after 80k records itself.
I tried changing the configuration the server Startup arguments from the console (Server Start and then Arguments) and then restart.
I just wrote the same thing there -Xms1024m -Xmx1024m
I guess I am missing something. Please share your answers.
Environment :
Win2k8, weblogic 10gR3, jdk 1.5. The application is installed as a service.
Thanks,
Neetesh

If you are not using NodeManager, then I don't think those server settings actually control anything. If you are just exploring WLS, then I suspect you are simply starting an AdminServer in a basic domain and don't have a cluster/nodemanager based environment. I could be wrong, please correct as needed!
If you are simply starting your WebLogic Server instance using the startWebLogic.sh|cnd script, you can set an environment variable on the command shell that will be picked up and used when the server starts.
set USER_MEM_ARGS=-Xmx1024 -Xms1024m
* apply appropriate *nix changes as appropriate.
Then use the startWebLogic.sh|cmd script to start the server and test your application.
It may very well be the case that your particular application consumes > 1GB heap so you may need more. Remember that you now have a server environment running over your "main" class, so there is bound to be more memory used that could be just sneaking your heap use over 1GB. For example.

WEBLOGIC - java.lang.OutOfMemoryError: Java heap space

hi,
i am using Weblogic 10.3 in production mode
We are getting error " java.lang.OutOfMemoryError: Java heap space " frequently , and
we are using the default args
JAVA Memory arguments: -Xms256m -Xmx512m -XX:MaxPermSize=512m
OS - > Windows Server 2003
please help
Regards
Jeethi George

Hi George,
The Setting you have provided is wrong ...that is the reason you are getting OutOfMemory in Heap.
Your Setting is (As you have mentioned in your very first post): JAVA Memory arguments: -Xms256m -Xmx512m -XX:MaxPermSize=512m
Just a Bit Explaination:
Formula:
(OS Level)Process Size = [ Java Heap (+) Native Space (+) (2-3% OS related Memory) ]
PermSize : It's a Netive Memory Area Outside of the Heap, Where ClassLoading kind of things happens. In an operating System like Windows Default Process Size is 2GB (2048MB) default (It doesnt matter How much RAM do u have 2GB or 4GB or more)...until we dont change it by setting OS level parameter to increase the process size..Usually in OS like Solaris/Linux we get 4GB process size as well.
Now Lets take the default Process Size=2GB (Windows), Now As you have set the -Xmx512M, we can assume that rest of the memory 1536 Mb is available for Native codes.
(ProcessSize - HeapSize) = [Native (+) (2-3% OS related Memory)]
2048 MB - 512 MB = 1536 MB
THUMB RULES:+
MaxPermSize = (MaxHeapSize/3) ----Very Special Cases
MaxPermSize = (MaxHeapSize/4) ----Recommended
In your Case -Xmx and -XX:MaxPermSize bith are same ....That is the reason you are getting the OutOfMemory Error in Heap.
We should increase/tune the MaxPermSize when we deploy a very large application (like a WebApplication which uses many JSPs, or PageFlows/Portal framework etc.) in our Server.
What should be the exact setting of these parameters depends on the Environment /Applications etc...
But Just try -Xmx1024m -Xms1024m -XX:MaxPermSize256m
Another recommendation for fine tuning always keep (Xmx MaxHeapSize & Xms InitialHeapSize same).
Thanks
