Java.lang.OutOfMemoryError -- Is there a way to limit BPEL instances number
Hi All,
My BPEL process is using JMS adapter to read the JMS queue. Whenever a new message arrives, a new BPEL instance is created. However, when the message gets bigger and multiple messages arrive at queue at the same time, the OC4J gets java OutOfMemory (heap space) error and was forced shutdown. I'm wondering if there's any way to limit the BPEL instance created, say, only one at a time, and the messages would be processed in sequence. Would this be a good way to not use so much heap at one time? Is there a way to limit the BPEL instance created?
Thanks for your help!

Take a look at how to configure Jms polling interval (talks about a property that you can set to introduce a delay in between dequeues). That might be of some help to start with.
It is supposed to work exactly the way you want it i.e the activation agent does a dequeue and hand off to bpel engine (which creates an instance and uses the same thread to run as much of that instance as possible i.e till the first dehydration point). So, if your process has a dehydration point right at the beginning (which could be due to invocation of another async process, or wait or ...), you could very well see this thread go right back and process the next available message.
I believe this is a generic problem that is not necessarily jms adapter specific. One way would be to split up your process into three processes:
1. "Kickoff" process which contains just a "receive" associated with the activation agent followed by an invocation of a "Controller" process
2. "Controller" process which checks for the provided input as to which process it needs to invoke, and then goes on to check how many instances of that process are currently running; if this number is below a certain threshold, kick off the main process providing it the necessary payload gotten from the "KickOff" process
3. "Main" process which is same as your current process except that it is a typical async process without the adapter "receive" partner link
So, the idea being that for any process where you want to introduce a control-flow mechanism, you would split it into #1 and #3 above. Have one generic Controller process, which caters to all of the processes.
Would be interested in learning if others have solved this in a generic way.

but when I change it to

<partitionBlobTranslator>oracle.spatial.network.lod.PartitionBlobTranslator11gR2</partitionBlobTranslator>
The application starts without the obove mentioned error. -

I am using Router from 11g. The web.xml from 10g does not have logs_id parameter and servlet mapping.... May I add logs_id parameter in web.xml?
Here we have contract with oracle. But I could NOT find any thing about patchs for routeserver... I am downloading "configuration manager" to update my metalink. Could you tell me tip about where are routeserver patchs?
Tks a lot,
Daniel

Serious system error while executing the query: java.lang.OutOfMemoryError
From ALSB, we are trying to insert records in a table, by calling the ALDSP webservice. It is working fine when the xml (ie., given as input to the ALDSP webservice) is small. But facing the following error when the input xml size is large.
<ALDSP> <BEA-000000> <Product> <Serious system error while executing the query:
{ld:ABC/Test}createTest:1
java.lang.OutOfMemoryError: Java heap space
We do not want to increase the heap size. Is there any other way we can solve this problem?In logical dataservice of ALDSP we have created a procedure called createTest, which is used to insert mulitple rows in the table. We have created a webservice for that logical DataService.
Using the ALSB, we are calling the webservice -> createTest Operation and we are passing xml as input to that createTest function.
Input xml:
<ns1:createTest>
<ns1:createTemps>
<ns0:createTemp>
<ns0:field1>1</ns0:field1>
<ns0:field10>test1</ns0:field10>

<ns0:field10>test2</ns0:field10>
</ns0:createTemp>
</ns1:createTemps>
</ns1:createTest>
each ns0:createTemp represent a row that need to be inserted in the table.
When the number of ns0:createTemp is less ( when the number of rows that need to be inserted is less) then no problem occurs, it is getting inserted properly. But when there are more number of ns0:createTemp then we are getting the following error

Trouble with "java.lang.OutOfMemoryError: Java heap space"
Hello,
I use a Java-based modeling tool that very few out there are probably familiar with. This tool allows me to run models (program) from within the development environment, to create Applets or create jar files that can be executed in a stand-alone fashion.
I am using a database on my local harddrive to read in some data using JDBC, so am not using the Applet option with certificates. The development environment is expensive, so can't be distributed. That leaves the stand-alone option.
The model (program) I've written runs perfectly fine in the development environment and, previously, has worked fine as a stand-alone program. However, the stand-alone option isn't working anymore, because I keep getting this error.
I am not much of a Java programmer; I'm learning as I go along. If anyone can help me solve this, I'll be most appreciative

Hi All
here my java class trying to read a txt file(which is having size of 60MB).and putting each line into a Vector class. problem is ,upto certain number of line it is reading properly and putting into vector..after that it is giving error like Exception in thread "main" java.lang.OutOfMemoryError..what is the problem and how to rectify this one..anybody help me on this.
actual situation is one txt is there in that 80 lakhs of lines of content is there..java file trying to read each line and put it into vector or stringbuffer and split it into two lines like key=value and put it into hashmap object.then finally iam creating new file(.properties) and writing these hashmap data on it. if you want clearly..please look into below code..

System.out.println("Closing asset.properties:" + new Date(System.currentTimeMillis()));Theres a number of ways you can improve your memory usage:
1) Build you map as you read in your file.
2) Use StringBuffers in your map - do not use "asshaj" + "ashaskj" This is very memory intensive
If you still run out of memory try running the JVM using -Xms128m -Xmx512m or higher -
Binary conversion of a big image leads to "java.lang.OutOfMemoryError"?
Hi,
My program loads a black and white 1 bit depth image of around 20 - 30mb. When I try to convert it to binary image, it gives the following error: java.lang.OutOfMemoryError: Java heap spaceI am converting a bufferedimage to binaryimage. I used the following conversion method:
// This method converts an image to a binary image:
public static BufferedImage convert (BufferedImage src, int type)
int w = src.getWidth ();
int h = src.getHeight ();
BufferedImage dst = new BufferedImage (w, h, type);
Graphics2D g = dst.createGraphics ();
g.drawRenderedImage (src, null);
g.dispose ();
return dst;
}The program was working well before but now it keeps giving the heap memory error which is really weird. Is there any way I can fix this? Can anybody suggest a better way to convert a black and white image to binary data. Thanks.You could increase maximum memory (-Xmx): [http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html]

I have also changed the JAVA_OPTS to -Xms128m -Xmx512m but this didnt solve the issue.

at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source)Check your code where u set the connection query; there's a procedure in my DBConnection class, looks like this:
public void setQuery(String query) throws SQLException {
this.query = conn.prepareStatement(query);
Should look the same for u, at least similar.
I set the query this way: dbConn.setQuery("insert into groups (id, code, sectionID, languageID, year, no_students) values (?,?,?,?,?,?)");
I had to insert 24,827 records into a table, and it throws the heap space exception u mentioned when it reaches 12,667. So what i did was to put dbConn.setQuery(...) outside the loop, and inside the loop it remains to set the parameters and execute the query from connection. It works for me. Hope will help u save some memory space. -
Big ANE causes java.lang.OutOfMemoryError when packaging Air application
Hi,
I'm working on an Air mobile game that uses ANE on iOS and Android. I'm in the process of creating a new ANE and face a problem on the Android side.
My ANE requires an external framework (Burstly, http://burstly.com). If I just link the Android project to Burstly's .jar file, I get errors in "adb logcat", like:
I/dalvikvm(16074): Could not find method com.burstly.lib.BurstlySdk.init, referenced from method com.freshplanet.burstly.functions.InitBurstlyFunction.call
In order to include Burstly's files in my own .jar, I unzip Burstly's .jar file and repackage them with my compiled code in a unique .jar (following advice on http://stackoverflow.com/questions/7732742/air-3-native-extensions-for-android-can-i-how-t o-include-3rd-party-libraries).
Problem: Burstly's SDK includes thousands of files. It doesn't create any trouble when packaging the ANE, but when I try to package the Air application, I get the following error:
dx tool failed:

I read that the solution to eliminate this error is to give Java the parameters "-Xms...M -Xmx...M", with "..." being a high-enough number. Note that I'm working on a machine with 8GB of RAM. I tried to package the app in command line to be able to pass these parameters:
/usr/bin/java -Xms512M -Xmx4096M -jar "/Applications/Adobe Flash Builder 4.6/sdks/4.6.0air31/lib/adt.jar" -package -target apk -storetype pkcs12 -keystore [...].p12 Main.apk Main-app.xml Main.swf -extdir "/Users/alex/Documents/Adobe Flash Builder 4.6/.metadata/.plugins/com.adobe.flexbuilder.project.ui/ANEFiles/front-end-mobile/com.ado be.flexide.multiplatform.ios.platform"
But when I run a "ps -ef | grep java", I can see that adt runs another Java program (dx) without transmitting my -Xms -Xmx parameters:
/usr/bin/java -jar /Applications/Adobe Flash Builder 4.6/sdks/4.6.0air31/lib/android/bin/dx.jar --dex --output=/private/var/folders/t9/3kw74cx14nv2xg9tgmx9m1jc0000gp/T/b5757d93-1e93-439c-8f6d -c93e4933f6f1/outputDEX.dex [... bunch of jars]
Any idea to solve this issue?
Thanks
AlexI solved my issue by setting the _JAVA_OPTIONS environment variable. (Note: there are two underscores)
I added the following line to my .bash_profile:
export _JAVA_OPTIONS="-Xms1024m -Xmx4096m -XX:MaxPermSize=512m"
Now everytime a Java program is launched from the command line, I see the following message:
Picked up _JAVA_OPTIONS: -Xms1024m -Xmx4096m -XX:MaxPermSize=512m
And my application packaging runs just fine now.
I still have an issue though: this trick solved the problem for packaging the app from the command line, but the _JAVA_OPTIONS are not picked up when packaging from Flash Builder, so it still crashes there.
Note that my Adobe Flash Builder 4.6.ini contains the following options:
-Xms512m
-Xmx1676m
-XX:MaxPermSize=512m
-XX:PermSize=64m
1676m is the highest number I can put before Flash Builder refuses to launch. I'm not sure if these parameters are actually passed to the VM that runs de dx.jar program, or if it's just for the ActionScript compiler. But anyway my app packaging still crashes in Flash Builder.
If someone knows a way to force Flash Builder to pickup the _JAVA_OPTIONS set in the command line, let me know :-)
Thanks

Java.lang.OutOfMemoryError: Perm Space in Weblogic10.3
Hi Friends
I installed an weblogic server on my machine with 1GB RAM, windows XP sp2.
I made simple application and deployed it on the server just after few sec of usage the weblogic server is giving this error
java.lang.OutOfMemoryError: Perm Space
i deployed the application in new domain that i created and the application is using the jdbc connection in weblogic rather then the urlI am also getting the error
Weblogic 10.3 gives out of memory
Followings thing I have done
1) Increased the -Xms512m
2) Increased the -Xmx1024m
3) Increased the max perm size in setdomainenv.bat
Is there any other way to resolve this issue I have a 2 GB system .
It is a production machine and the size of the log is around 4 GB .When analysed the log I found many connection refused error

Getting java.lang.OutOfMemoryError: PermGen space
Hi,
In JCAPS5.1.1 after deploying my project, i am getting following error.
#|2007-02-20T16:38:48.319+0530|SEVERE|IS5.1.1|STC.eWay.batch.com.stc.connector.batchadapter.system.BatchInboundWork|_ThreadID=50; ThreadName=Worker: 140;stacktrace-id=13;|Exception in BatchInboundWork, BatchInboundWork terminated, e=java.lang.OutOfMemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space
|#]
Earlier also i have deployed projects but never
faced this type of error.
Please let me know Is there any work around to
rectify this kind of OutOf memory error.
Thanks

VenkateshSampoornamHi moonsit !
Yes, currently our PermSize is set to 384mb (-XX:MaxPermSize=384m).
Hi Alan !
Yes, we get the same conclusion, after deploy or redeploy projects we get the OOME, but I was expecting that SUN support resolve this issue and not use the stop/start as a way to fix that, since sometimes it will impact our production environment.
I searched over internet and discover that some thirdpart libraries version has memory leaks. It's the case of apache commons-logging 1.0.6 and apache commons-beanutils 1.6. I found them in the lib directory of Integration Server in JCAPS 5.1.3 and may be there is more thinks like that. Both libraries has newer version with this issue fixed. Maybe SUN need to be adviced about that.
Does anyone else found a way to fix that ? Or a workaround that we can do to avoid the restart of LH ?
Thanks !

Diagnosing java.lang.OutOfMemoryError: PermGen space
I am getting this error on our test instance:
Exception in thread "Thread-96425" java.lang.OutOfMemoryError: PermGen space
(We are using JDK 1.5.0_03)
What tools can I use to inspect the contents of PermGen? In particular, is there a way to see all the interned String objects?
I tried jmap -permstat, but it only shows perm gen usage based on classloader. I wasn't sure how to check the intern Strings.
Thanks
SamHi All,
We just to add few things before i go into deep as to what is the root cause that might cause Out Of Memory due to Permanant Generation.
Well recently i had faced this issue in one of the biggest application used in UK.I faced this issue and the resoultion for this took to almost 3 months.Now the issue is resolved.The reason for this was in the application itself.
Well to diagnose this, please add the following parameter into the JVM Options of the instance you are using it.DON'T use parallelGC.
-verbose:gc
-XX:+PrintClassHistogram
-XX:+PrintGCDetails
After this JVM options are added, restart you instance and then check the server.log file.You will see lots of classes.Please do a analysis of this classes.You will observe that some of the classes keeps on growing even after the FULLGC is done.It means that there is some problem you need to check either at the application layer as to which classes are creating this problem.Normally classes or sometimes API's being used by the application can caused PermGen issue.
Well String.intern method normally being used by XML api's .
Please drop me a mail for any further information you require.My id is

What is the exact tuning I need to start up a simple managedserver in Weblogic 10.3.2, Linux Ubuntu ?Hi,
I doubt that the following USER_MEM_ARGS which u have mentioned in the *"setDomainEnv.sh"* is not taking effect....
USER_MEM_ARGS="-Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m"
Can u check the STDOUT of the Server or first few lines of Server Log....there u will be able to see that what value it is taking actually to startup. Sometimes it happens if we set the MEM_ARGS values in if---else block then mistakenly it takes the default values....
Because 512M Memory for PermGen is enough for most of the Applications and Servers.
One more thing .... How r u starting your Servers ...Using StartScripts or using NodeManager (through AdminConsole)? Because there are different ways of setting the Memory Arguments for these two scenarios. Like mentioned in the following link: http://weblogic-wonders.com/weblogic/2010/03/26/nodemanager-based-managedservers-setting-mem_args/
Thanks

Java.lang.OutOfMemoryError: PermGen space - help pl

csbHello YoGee
Thank you for the info.
In fact its an applet-servlet comm appl that i am
running. The servlet creates the object and is send
to the applet where it is displayed. That is an instance of a class not the class itself.
The applet then
creates an object and is sent back to servlet for
updating the database. So its objects being sent back
and forth. Do i need to give the command in the
prompt? Can you be a bit more specific?
Again if the object created at the applet is set to
null ..ie.
sub s = new sub(id,add,zip) ;
s = null;
Is object s a candidate for garbage collection?This has nothing to do with the original question.
If there are no active references then it is available for collection.
What i mean is, if i no longer want the object s , is
there any way to completely(explicitly) remove it
from the memory?No.
Maybe you are looking for
