After starting the server when i see administrator console and get log-in it throws below exception. Root cause of ServletException. java.lang.OutOfMemoryError: PermGen space at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:791) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at weblogic.utils.classloaders.GenericClassLoader.defineClass(GenericClassLoader.java:335) at weblogic.utils.classloaders.GenericClassLoader.findLocalClass(GenericClassLoader.java:288) Truncated. see log file for complete stacktrace I did lot of google and found some solution to initialize JAVA_OPTIONS like -XX:xmx and etc. I tried to set this in startdomainenv.cmd file but with no luck. Please help. Any pointers will be highly appreciated.

Regarding Weblogic, set the JAVA_OPTIONS and see if these options are properly passed in as parameters into your Java process. You can also directly set these parameters in the startWeblogic.cmd script. To check that your JAVA_OPTIONS are set properly, add echo %JAVA_OPTIONS% into the startWeblogic.cmd script and see the output. Also, you can use e.g. jConsole, jstat, or jmap to monitor Heap usage of the Weblogic process at runtime. This will show you the sizes and occupation of the PermGen. share|improve this answer edited Feb 19 '13 at 5:39 answered Feb 19 '13 at 0:58 Ales Plsek 5,43433173 thank you.It is working now –nakul Feb 19 '13 at 19:17 This works, just be careful as the JAVA_OPTIONS will effect all of java on your machine that may utilize this system variable. If the problem is specific to Weblogic, alter the setDomainEnv.cmd as D

I am a newbie working with WLS I keep facing an issue where the machine(16gb ram and 500gb HDD ) were weblogic is deployed keep getting out of memory .. I only used the default configuration for the weblogic deployment that came with the weblogic installation . There is only one adf application running on https://community.oracle.com/thread/2456383 the weblogic which is accessed by around two to three people .. What additional changes needs to be done? Second question is that is there a way to find how many DB connections are open currently in the weblogic and how long its been open? What debug option can be used to find the reason for out of memory erro?

Re: Problem with weblogic 11g out of memory Kalyan Pasupuleti-Oracle Oct 19, 2012 2:07 PM (in response to 998899-Oracle) Hi Sam, By default weblogic will give min heap as -Xms256m and max heap as -Xmx512m and if you are using Sun JDK it will use MaxPermsize as 128m. Now to avoid such OOOM (Out of Memory) issue try to increase these parameters. If you are using 64 bit I would suggest to use 2GB Minimum or 8Gb
Looking for JDevelop... » Solving PermGem Errors with the Integrated WLS in JDeveloper By Shay Shmeltzer-Oracle on Mar 04, 2009 One bug that we are aware of in JDeveloper 11g is that there is a memory leak if you do many repeat runs of an application.However there is https://blogs.oracle.com/shay/entry/solving_permgem_errors_with_th an easy way to eliminate most of those by changing the a setting in the specs for the integrated server.Locate the file: setDomainEnv.cmd which should be at: [JDev Install Dir]\jdeveloper\system\system11.1.1.0.31.51.88\DefaultDomain\binThere find the line: set MEM_MAX_PERM_SIZE=-XX:MaxPermSize=128m and change it to: set https://coderanch.com/t/429424/Performance/java/PermGen-Memory-WebLogic MEM_MAX_PERM_SIZE=-XX:MaxPermSize=512mNow try and run your projects again.

I have external WLS server and I'm deploying my applications to that external server. And it happens there too. After three or maybe four deployments I get PermGen Error. Server settings are JAVA Memory arguments: -Xms256m -Xmx512m -XX:CompileThreshold=8000 -XX:PermSize=48m -XX:MaxPermSize=128m . WLS Start Mode=Development I will change this, I just wanted to say that maybe this error is not JDevelopers deployment process issue. ADF on! out of memory Janez Posted by jlavric on March 04, 2009 at 09:54 PM PST # Shay thanks for this - it solved my problem - it was getting very annoying but this setting seems to have done the trick. Darragh Posted by Darragh Duffy on March 06, 2009 at 10:01 PM PST # I used such settings before, but it seems the solution for me was to clean "drs" directory if application runs to slow or cached previous deployment. MEM_MAX_PERM_SIZE=-XX:MaxPermSize=512m i think is to much for Perm memmory - even for big applications. Probably the problem is not in this settings. Posted by Pavel on March 08, 2009 at 05:34 PM PDT # drs directory is the deployment dir of weblogic and has NOTHING to do with mem. You clean drs to remove old redeployments. 512MB might be too much but this is cos weblogic has a mem leak. So eventually you will run out of mem. So, the > the permsize the > the time you get with no out of mem error. Savvy? PS: Yes the problem is in the mem leak if that is what you mean, but untill then that is a damn good workaround. Posted by Jerome on March 09, 2009 at 11:27 PM PDT # It got better when configuring these settings, but I still get PermGen error after like 10 runs of my application. Before I configured WLS, it happened about every 3rd time I r
This Site Careers Other all forums Forum: Performance PermGen Memory issue in WebLogic 10 Deon lim Greenhorn Posts: 8 posted 7 years ago I have issue on the permanent generation space which will increase until it hit Java.lang.OutOfMemoryError: PermGen space. 1. The Java.lang.OutOfMemoryError: PermGen space can be solved by increase the MaxPermSize. Is it same if just increase the PermSize without MaxPermSize? 2. Where can get the gc log file if -verbosegc -XX:+PrintGCDetails parameters was added? 3. How to trace unloading of classes by adding parameter -XX:+TraceClassUnloading? 4. What action can be taken if the issue still happen after increasing of MaxPermSize? Below are some info for the server.

It links to an article on how to fix them. In my experience, third-party libraries can be the cause (I'm looking at you, Struts 2), so you may be left with no alternative than an occasional shutdown-startup cycle. [How To Ask Questions On JavaRanch] Deon lim Greenhorn Posts: 8 posted 7 years ago Hi, Anyone can help on question below? Is it mean that the maximum permanent generation size can up to 512MB if we set -XX:PermSize=512m even we did not set the *MaxPermSize*? Deon lim Greenhorn Posts: 8 posted 7 years ago Hi Joe Ess, Can give some example of what kind of third-party libraries can cause this issue?

Is it mean that the maximum permanent generation size can up to 512MB if we set -XX:PermSize=512m even we did not set the *MaxPermSize*? PermSize is the initial permanent generation size. Maximum size is by default 32m for client machines and 64 for servers. In this case, I *think* since you are not defining it, it would be taken equal to PermSize. In my opinion, it is better to give MaxPermSize instead of PermSize so that you do not take the memory if not required.
