[Java6] OutOfMemoryError after java 6 deployment.

Hello.
We have developed an applet the works with no problems on Java 5.
Since we deployed Java 6 JRE, I have a lot of OutOfMemoryError randomly.
That's the stack trace :

Using exceptions for normal processing flow is a bad idea. Far as I know bad idea in every language that does exceptions.
Does anyone know why it would be slower in Java 6?You could look through the release notes.

MDB TimerManager Error after updating a deployment

We are running weblogic 10.3
After updating a deployment, our app is consistently getting the following error:
java.lang.IllegalArgumentException: Existing timer manager has different work manager.
TimerManager requested: JMSPoller-TestMessageBean
When we perform the update, we first stop the deployment (selecting when work completes) - then update the deployment.
The only way to clear the error is to bounce the server - which we can't always do without interrupting other applications.
We have not configured any special workManagers - the weblogic configuration is quite vanilla.
the following is an exerpt from the weblogic-ejb-jar.xml for the bean:

Issue with Default Variable in WAD after Java Patch 7.01.7.31

Hello all,
I'm running into an issue with the Web Application Designer Template execution for a particular default variable. This started occuring after Java Patch 7.01.7.31 we had implented over the weekend.
The issue is when Executing the WAD Template, we have a selection screen with a variable with default values assigned to it. When leaving the default values and hitting Ok to execute through the screen does not register and stays as is and I get a message at the top with the following: Characteristic Prob % Number has no master data for "1.00" or you do not have authorization.
This only seems to occur for this default variable on info object Prob % Number, the other default variables seem to work fine. Also another note when clearing out the values it returns data and executes through. The value 1.00 is also a valid value in the cube and also in the output display. If we run this report in the BEx analyzer, the selection screen executes through with the default variable perfectly fine, this is only an issue with the Web Application Designer Template.
Has anyone ran into this? I've searched and have not found any notes as of yet.
Thank you,
-Andy

Dear Andy,
Please raise this to SAP, seems like a strange problem this needs to be addressed by OSS note only.
Close this thread once you get a solution.
Regards.

Is it possible to edit a MDT Task Sequence after starting a deployment, between Hyper-V snapshots?

Using a Hyper-V VM, I take snapshots of my base image build between major sections (automatic updates, application installation, scripts and extras, etc.) with the intention of being able to go back to that area and look at it for troubleshooting's sake.
Each of these snapshots is manually taken during a pause in my MDT task sequence (using LTISuspend). I would like to be able to roll back to these snaphots make edits to the task sequence (obviously to sections that haven't yet run), then resume and
see the changes implemented - but I don't know where the task sequence file(s) resides on VM being imaged, or if that can be changed after kicking it off at the very start of the build.
Is it possible to replace the task sequence file (and any other necessary files) that are cached locally on the VM during the imaging process? Where are those files located? Or any other way to implement changes to my task sequence so I wouldn't
have to start the image build completely from scratch?
This build takes about 6 hours. Having to make even the slightest modification causes me to lose an entire day, so this would be golden even if I have to manually edit certain files!

Hi,
Based on my known, you cannot edit the task sequence after starting the deployment.
However, I suggest you ask this issue in MDT forum for more professional solution:

Sort order in Java Application (deploy in Oracle oc4j container)

I have a Java application deploy in Oracle OC4J container (EAR file).
In my Java application (jsp), I have a SQL statement who return data but the
sort order is wrong. The letters "é" and all characters with accents
appears at the end of the result.
I tried many things to change the sort order (NLS parameters in database
and OAS10g parameter files).
When I use SQL*plus on database server, that's working.
The sort order is wrong when I use the java application.
Somebody can tell me what and where is the NLS parameters to change ?
Thanks
Robin

Robin,
I'm only guessing, but it could either be related to the java locale or the CHARSET attribute of the HTML header -- and nothing to do with the NLS parameters.
Maybe you should try the Globalization Support forum?
Good Luck,
Avi.

After Java patch 1.7.0_07 ENable applet plug-in and Web start checkbox is gone!

Hello all,
Using ML 10.8.1 and Safair 6.0
After Java patch 1.7.0_07 ENable applet plug-in and Web start checkbox is gone! The check box to enable Safari to load Java pages is 100% gone, missing, just not there anymore.
When I go to the Java test page it shows that I have Java 7 loaded. Has anyone else run into this problem or have a solution to enable true load loading in Safari and bring back the Enable applet plug-in and Web Start application check box in ML...
Thanks

I found out something very interesting. I noticed that another page would show up for less than have a second before the ML Java Preference would show up. I did a video recording of this and moved frame by frame. I show that the page / pane showing up had the following option:
Run applets: in their own process
within their browser process
Both boxes for the two are unchecked.
Then this page would disappear and nother would show up without the option / check box
Enable applet plugin and Web Start applications

Java application deployment tool

Hey everyone, i'm having some serious difficulty deploying an ejb application on bea weblogic.
I cannot find the java application deployment tool, or any concise documentation for that matter.
I have experience writing jsps, javabeans, servlets etc. and deploying them with ant.
Thanks for any help on this tool and or deployment techniques for ejb.
/jeff

You may want to direct your query to one of the web forums run by BEA. Most folks here are familiar with the j2ee specs and the Sun implementations of those specs.

OutOfMemoryError in Java ME SDK 3.0, 3.2, 3.3 and 3.4 emulator

Hello together,
sorry for restarting this topic again, but the original discussion
OutOfMemoryError in Java ME SDK 3.0 and 3.2 emulator
has been archived while I was concerned with different things in the meantime. Now returning to Java ME programming again, I find that the problem still persists, at least for the most recently released emulator 3.4. Also the suggestion to increase the heap size via command line parameter is not working. Any further ideas are still appreciated!
Regards,
Oliver Pfeiffer

Try to adjust the heap size by starting the emulator from the command line
and add the parameter "-Xheapsize=10M" this will give you a heap size of 10 Meg.

Windows Image Deployment - WinPE - Execute Command After Server Image Deployment but Before WinPE Reboot

Simplified version: Execute command in WinPE after server image deployment but before WinPE reboots.
I have a custom ISO with a boot.wim and install.wim for deploying Windows Server to our environment. Our environment does not allow DHCP and we have no static IPs available at build time so this will all be done with no internet connection during all phases
of deployment.
We have a custom HTA form that generates an XML file based on user input and stores it on the RAMDisk during WinPE. How can we move this XML file from the RAMDisk to the deployed Windows Server image?
Thanks in advance, Tim

I believe you should be able to do this during the offlineServicing configuration pass. You would just need to add into your answer file a command or script to copy from the XML file over to the newly created C:\ drive.
I don't have System Image Manager installed on the computer I'm using but if I recall there is a spot during the offlineServicing pass to execute custom commands. You would just add your script path there, the WinPE system drive letter is
X:\ , and I think the target drive letter Windows is installed to might change depending on how many devices you have hooked up so do a test install and hit SHIFT-F10 , from there you can run diskpart > list volume to see where the new Windows
install is located.
Another alternative could be using a USB drive as your install media, then you can run a script during offlineServicing to copy that XML over to the USB drive.

Java webstart after java 2012 006

Hi,
I updated last week my OSX Mountain Lion with the java for 2012-006 which disables the java web start and plugins.
I need however both web start (for starting .jnlp files) and plugins (vpn access).
Was able to restore some stuff from timemachine, currently my system is showing having java 1.6.0_37, my java preferences are showing Java Web start enabled (also the /Users/$USER/Library/Preferences/ByHost/com.apple.java.JavaPreferences.${MAC_UU ID}.plist shows this), but starting a .jnlp file, asks me every time to enable Web Start Applications and the launch fails.
Using java7 doesn't solve my problem either, the application itself does not run yep in an java7 environment.
Ramón
java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

Did find the fix myself, besides the restore from timemachine, the correct definition of de symbolic link to /usr/bin/javaws was the fix.
The complete solution:
Restore from timemachine
/System/Library/Java/Support/CoreDeploy.bundle
and /Applications/Utilities/Java Preferences.app

OutOfMemoryError after many redeployment on Integrated WebLogic Server

Hello everyone.
I noticed that deploying many times the same web application on the Integrated WebLogic Server I have the following message:
<Critical> <Health> <BEA-310003> <Free memory in the server is 4.087.912 bytes. There is danger of OutOfMemoryError>
Typically, shortly after this message, the application crashes and the following error appears:
<Error> <Kernel> <BEA-000802> <ExecuteRequest failed java.lang.OutOfMemoryError: Java heap space. java.lang.OutOfMemoryError: Java heap space>
This behavior happens when I redeploy many times the same application (around 15 / 20 times) using the start function from the index page or the adfc-config task-flow. This behavior doesn't happen if I undeploy first the application.
It happens with different applications and also in different JDev versions (e.g. 11.1.1.3, 11.1.1.6, 11.1.2.3).
Please also notice that the time of deployment increases with the number of redeployment. It seems that each redeployment fills a quantity of memory, that terminates after many redeployments.
There is some shrewdness to take for redeploy applications?
Thanks in advance.
Manuel

Timo,
thanks for your response. Yes, currently restart the Integrated WebLogic Server is the action that I perform. I could prevent the error stopping the server after 5 / 10 redeployments, but this could happen often, especially if I'm working on back-end side.
My question is only to avoid to lost time for any restart of the server. If there is no solution to prevent this, patience.
Manuel

OutOfMemoryErrors after migrating WLS 6.1 to 8.1

I work on a project that has been running on Weblogic 6.1 SP4, using Sun JDK 1.3.1_04
on Solaris 8 for well over a year. We recently migrated to Weblogic 8.1 SP2 using
Sun JDK 1.4.1_05. We did have to make minor changes to our application (deployment
descriptors and what-not), but nothing substantial.
Since the migration, I have seen numerous OutOfMemoryErrors on production, and
I've been unable to determine the cause. I am currently fighting to make JProbe
to do something useful, but in the meantime I am instrumenting the garbage collector.
Below are our memory and garbage collector settings:
MEM_ARGS="-ms512m -mx512m -XX:NewSize=128m -XX:MaxNewSize=128m -XX:MaxPermSize=192m
-XX:SurvivorRatio=8"
JAVA_OPTIONS="-verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC
$JAVA_OPTIONS"
When we get OutOfMemoryErrors, it appears that the VM has plenty of space. For
instance, this is the last message logged before the first OutOfMemoryError this
morning:

As you can see, there's plenty of room in the tenured generation (71% of total
in use), and the perm gen has only grown to 63M of its allocated 192M. Yes, 192M
seems huge but we're trying to overshoot Java's needs to get the VM to stop crashing!
The perm size can grow beyond that, as is shown by the most recent OutOfMemoryError
today:

} , 2.4384700 secs]
Are there any suggestions on how to proceed from here? As I said, I'm trying
to get JProbe to detect a memory leak, but I've found nothing so far.
Thanks,
Andy

When we get OutOfMemoryErrors, it appears that the VM has plenty of space.
For
instance, this is the last message logged before the first OutOfMemoryError
this
morning:

As you can see, there's plenty of room in the tenured generation (71%
of total
in use), and the perm gen has only grown to 63M of its allocated 192M.
Yes, 192M
seems huge but we're trying to overshoot Java's needs to get the VM to
stop crashing!
The perm size can grow beyond that, as is shown by the most recent OutOfMemoryError
today:

Are there any suggestions on how to proceed from here? As I said, I'm
trying
to get JProbe to detect a memory leak, but I've found nothing so far.
Thanks,
AndySometimes it is related to the OS having problems with things like the number
of files open etc conurrently at any one time. With the new SP, perhaps there
is an additional overhead that has caused a problem.
I have spend weeks and weeks before working on Out of Memory errors with multiple
instances of Weblogic, Wepshpere or Dynamo and they have all been related to the
Kernel limits.
Look at the following docs and ensure you have your OS limits to set to the Solaris/Windows/AIX
or HP Unix recommendations:
