I'd say that the message is too big for your currently configured Java heap --> increase it.

Getting 'java.lang.OutOfMemoryError' while importing process flows.

Hello,
We are getting 'java.lang.OutOfMemoryError' error while importing process flows in our QA environment. This environment is not new. The same process flows were working perfectly fine till last week.
This week we had to delete the project in QA and reimport all the objects. Import went fine for all, except process flows. We could deploy all other objects as well.
We have tried increasing JVM in run_service.sh and owbclient.sh files by increasing -Xmx, -Xmx and Dlimit. We increased as far as 2048M ( This is the max memory available on our server)
We are using OWB version 10.2.0.2 and Oracle 10G over Linux. Did anyone of you face the same issue ? Please le us know the solution.
Thanks
Madhavi

Hi Madhavi,
Which locale language is shown in your OWB client configuration? We had this issue in previous versions (I haven't found it in this version, but I'm used to work with English since these previous versions) So we always adjust Preferences (Tools -> Preferences...) to see Appearance -> Locale -> English.
Try to change the locale language if it's your case.

Java.lang.OutofmemoryError while loading message in mapping

Hi,
I encountered a Strange problem while performing message mapping.
I have to transform Orders05 message into another message format(the size of the XSD file is 17 KB) which has got 100 elements(approx count) in it.
After selecting the source message(Orders05) when i tried to select the target message (whihc was imported into XI as external definations), the system hangs up and i get below error message.
Display Problem
java.lang.OutofmemoryError
Internal problem occurred (INTERNAL_PROBLEM)
MESSAGE ID: com.sap.aii.utilxi.swing.framework.rb_exceptions.INTERNAL_PROBLEM
The system i tried this was a P4-processor512 MB RAM. so i used my laptop(1 GB RAM Intel centrino) to perform the same. But no change in message mapping, but the only thing i noticed was the system did not hangup.
Later i went to perform the same mapping on the server 3 GB RAM, dual processor. Initially the message could be selected as target field. But after performing 2-3 field level mapping, the Design time hanged up. I had to close the session and open up again to perform 2-3 field mappings again. This went on for over 20 times and only then i could finish the entire mapping.
I have never encountered such a problem earlier. Is there any solution to rectify this. My problem is, i have to perform 10 such mappings :-((
Here is the complete errror i got .

Error in PI mapping "nested exception is: java.lang.OutOfMemoryError "

Hi Experts ,
I encounter an error in the PI mapping while calling a Java Mapping (Mercator Map)
Error Message as ::-
java.lang.RuntimeException: RemoteException in setMercGeneral: Error occurred in server thread; nested exception is: java.lang.OutOfMemoryError at com.philips.xi.mercator.MercatorCall.execute(MercatorCall.java:90) at
Could anyone suggest , how we can overcome this error message
I have also tried to restart the RMI Server , but that was not not helpful.
Regards,
Shweta

Sweta,
Is this a java mapping or Graphical, If Java, you should not run into this issue as you dont load the nested XSD`s.
Also the error message indicates outofMemory in mercator side when posting your Large message.

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:createTemp>
<ns0:createTemp>
 <ns0:field1>2</ns0:field1>
 <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
<ALDSP> <BEA-000000> <Product> <Serious system error while executing the query:

Could you please share your knowledge in this regard,

Well, if you're getting an out of memory exception then your memory settings are too low. Odds are there's a period of activity where the memory usage spikes above what you've configured for the VM.

HOW did you increase the heap space? As that is the only solution you have in this case really.
It is a known fact that POI can use up a lot of memory for big spreadsheets. If at all possible, I would try to switch to plain text comma separated files / tab delimited files. If you cannot do that, I would try to put a size restriction on the sheets that your application will process to get rid of the heap space risk. A sheet can contain 20000 records, or four sheets can contain 5000 records; in both cases you process the exact same data, but at only 25% of the total memory usage.

Java.lang.OutOfMemoryError: PermGen space error while creat weblogic domain

Hi,
OBIEE 11g installing in Linux server now. domain creation is in progress for about an hour and in log I can see below error.
Creating a new AdminServer Object ...
AdminServer port is 7001
Starting the domain ...
java.lang.OutOfMemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space
domain creation is still running and looks like it is struck to start domain no idea how to solve the issue. waiting to see whether domain creation successful.
I was searching on web and found below solution but no idea how to do it in Linux server. Please provide detail instructions to do it.
* java.lang.OutOfMemoryError: PermGen space
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Unknown Source)
at java.lang.Class.getConstructor0(Unknown Source)
at java.lang.Class.getConstructor(Unknown Source)
Solution: Increase the max permgen space -XX:MaxPermSize=256m
There can be a leak in the permgen objects. If tuning parameters do not resolve the issue, we need to use the memory leak detector tools and find out which instances in the permgen space are not getting cleared.
Refer: http://weblogic-wonders.com/weblogic/2010/12/30/different-out-of-memory-issues/
Appreciate for your help.
Thanks
Jay.

Hi,
The script that configures the domain $DOMAIN_HOME/bin/setDomainEnv.sh... it should detect you are using JDK from Sun (JAVA_VENDOR="Sun") and add -XX:MaxPermSize=512m automatically...
Simple solution, use JRockit... This problem only occurs with Sun JDK...
Alternatively, add manually -XX:MaxPermSize=512m to the last JAVA_PROPERTIES in setDomainEnv.sh then you will be sure it is there...
Cheers,

I am trying to config application in Sun One Portal server 3.0 SP5 , (Sun Solaris 8)during configuration I was trying to import some xml files however during the process I got the error :
Exception in thread "main" java.lang.OutOfMemoryError.
I tried increasing the size of the heap in jvm12.conf to 512 MB and even tried to run the command -Xms512M, but this didn't help.
Pls respond as asap.

Hi gimbal2,
yeah, its streaming the particular data (ie CUSTOMER) from input xml file and generate the txt file.
I tried like below . But this is also not working. Getting the same error.
java -Xmx2048m -mx2048m -Xss1024k -Xoss1024m
Any other possible solution on this?

Hi,
Yes,René van Wijk has said rite..
Just open the Weblogic console,
expand Environment-->Server-->(ur managed server)-->Server Start tab
Just enter the below lines in Arguments:
-Xms1024m -Xmx1024m -XX:MaxPermSize=256m
Then bounce your managed server
This should solve your problem

Exception in thread "main" java.lang.OutOfMemoryError(please help me )

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..
package test.utf8; import java.io.*; import java.util.*; public class AssetUtils
//static StringBuffer stringbuffer = new StringBuffer();
public AssetUtils()

do

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

FB 4.7 AIR 3.6 Flex 4.9 iOS packing - Exception in thread "main" java.lang.OutOfMemoryError'

I've got an error similar to Isaac_Sunkes' 'FB 4.7 iOS packaging - Exception in thread "main" java.lang.OutOfMemoryError',
but the causes are not related to what he discovered, corrupt image or other files, I'd exclude bad archive contents in my project.
I'm using Flash Builder 4.7 with Adobe AIR 3.6 set into an Apache Flex 4.9.1 SDK;
HW system is:
iMac,    2,7 GHz Intel Core i5,    8 GB 1600 MHz DDR3,    NVIDIA GeForce GT 640M 512 MB,    OS X 10.8.2 (12C3103)
The Flash project consists in an application with a main SWF file which loads, via ActionScript methods, other SWF in cascade.
I've formerly compiled and run the application on an iPad 1, IOS 5.0.1 (9A405), but got on the device the error alert:
"Uncompiled ActionScript
Your application is attempitng to run
uncompiled ActionScript, probably
due to the use of an embedded
SWF. This is unsupported on iOS.
See the Adobe Developer
Connection website for more info."
Then I changed the FB compiler switches, now are set to:
-locale en_US
-swf-version=19
Please note that without the switch    -swf-version=19     the application is compiled correctly and the IPA is sent to the device
and I can debug it, but iOS traps secondary SWF files and blocke the app usage, as previously told.
they work on deploy of small applications,
but, when I try to build a big IPA file either for an ad-hoc distribution, either for an debug on device, after some minutes long waiting, I get a Java stuck, with this trace:
Error occurred while packaging the application:

I've tried to change the Java settings on FB's eclipse.ini in MacOS folder,
-vmargs
-Xms(various settings up to)1024m
-Xmx(various settings up to)1024m
-XX:MaxPermSize=(various settings up to)512m
-XX:PermSize=(various settings up to)256m
but results are the same.
Now settings are back as recommended:
-vmargs
-Xms256m
-Xmx512m
-XX:MaxPermSize=256m
-XX:PermSize=64m
I've changed the Flex build.properties
jvm.args = ${local.d32} -Xms64m -Xmx1024m -ea -Dapple.awt.UIElement=true
with no results; now I'n get back to the standard:
jvm.args = ${local.d32} -Xms64m -Xmx384m -ea -Dapple.awt.UIElement=true
and now I truely have no more ideas;
could anyone give an help?
many thanks in advance.

I solved this. It turns out the app icons were corrupt. After removing them and replacing them with new files this error went away.

Error: java.lang.OutOfMemoryError when uploading CSV files to web server

Hi experts,
I have made a JSP page from which clients load csv files to web server. I am using Tomca 4.1 as my web server and JDK 1.3.1_09.
The system works fine when uploadiing small csv files, but it crashes when uploading large CSV files.
It gives me the following error:
java.lang.OutOfMemoryError
 <<no stack trace available>>
This is the code that I used to load files....
<%
String saveFile = "";
String contentType = request.getContentType();
if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0))
 DataInputStream in = new DataInputStream(request.getInputStream());
 int formDataLength = request.getContentLength();
 byte dataBytes[] = new byte[formDataLength];
 int byteRead = 0;
 int totalBytesRead = 0;
 while (totalBytesRead < formDataLength)
 byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
 totalBytesRead += byteRead;
 String file = new String(dataBytes);
 saveFile = file.substring(file.indexOf("filename=\"") + 10);
 saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
 saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1,saveFile.indexOf("\""));
 int lastIndex = contentType.lastIndexOf("=");
 String boundary = contentType.substring(lastIndex + 1,contentType.length());
 int pos;
 pos = file.indexOf("filename=\"");
 pos = file.indexOf("\n", pos) + 1;
 pos = file.indexOf("\n", pos) + 1;
 pos = file.indexOf("\n", pos) + 1;
 int boundaryLocation = file.indexOf(boundary, pos) - 4;
 int startPos = ((file.substring(0, pos)).getBytes()).length;
 int endPos = ((file.substring(0, boundaryLocation)).getBytes()).length;
 String folder = "f:/Program Files/Apache Group/Tomcat 4.1/webapps/broadcast/file/";
 //String folder = "10.28.12.58/bulksms/";
 FileOutputStream fileOut = new FileOutputStream(folder + saveFile);
 //out.print("Saved here: " + saveFile);
 //fileOut.write(dataBytes);
 fileOut.write(dataBytes, startPos, (endPos - startPos));
 fileOut.flush();
 fileOut.close();
 out.println("File loaded successfully");
//f:/Program Files/Apache Group/Tomcat 4.1/webapps/sms/file/
%>
Please can anyone help me solve this problem for me...
Thanx...
Deepak

I know it may be hard to throw away all this code, but consider using the jakarta fileupload component.
I think it would simplify your code down to
// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Parse the request
List /* FileItem */ items = upload.parseRequest(request);
// Process the uploaded items
Iterator iter = items.iterator();
while (iter.hasNext()) {
 FileItem item = (FileItem) iter.next();
 if (item.isFormField()) {
 processFormField(item);
 } else {
 // item is a file. write it
 File saveFolder = application.getRealPath("/file");
 File uploadedFile = new File(saveFolder, item.getName());
 item.write(uploadedFile);
}Most of this code was hijacked from http://jakarta.apache.org/commons/fileupload/using.html
Check it out. It will solve your memory problem by writing the file to disk temporarily if necessary.
