Oracle JRockit R28.2.2. OutOfMemoryError: classblock allocation

Hi Folks,
Well, we have a production Weblogic environment over Oracle JRockit Virtual Machine. The problem is that we are trying to avoid an " OutOfMemoryError" that is thrown everyday by a SOA Managed Server and causes a failure and stop of the managed server which then has to be restarted, causing applications downtime.
Platform:
Windows 64bits Server 2008 R2 Standard. 32GB RAM
Products:
Oracle JRockit R28.2.2
Oracle Weblogic Server 10.3.2
Oracle SOA and BPM Suite 11g R1 11.1.1.5 Features Pack
Oracle Services Bus 11g 11.1.1.5
The message error is the following:
java.lang.OutOfMemoryError: classblock allocation, 110787528 loaded, 84224K footprint, in check_alloc (src/jvm/model/classload/classalloc.c:215).
Attempting to allocate 7G bytes
There is insufficient native memory for the Java
Runtime Environment to continue.
Possible reasons:
The system is out of physical RAM or swap space
In 32 bit mode, the process size limit was hit
Possible solutions:
Reduce memory load on the system
Increase physical memory or swap space
Check if swap backing store is full
Use 64 bit Java on a 64 bit OS
Decrease Java heap size (-Xmx/-Xms)
Decrease number of Java threads
Decrease Java thread stack sizes (-Xss)
Disable compressed references (-XXcompressedRefs=false)
The following are the conclusions I have made about this problem:
- It is clear in the message error that this is not a Java Heap Size issue since those kind of errors usually look like: (Java Heap Space, getNewTLA, etc...) and the message clearly states: "There is insufficient native memory for the Java Runtime Environment to continue". Besides, the MissionControl recordings show that the heap is constantly being garbage collected and there are not memory leaks.
- The process size is about 10GB (7GB Heap Size and 4GB Native memory) but the platform consists of a 64 bit Windows 2008 Server with 32GB, so this is neither a "process size limit issue".
-According to this, it could be clear that the problem is that "The system is out of physical RAM or swap space" but this isn't true either, since the system has a 48GB max paging file (wich in fact is not being used) and most importantly, the system has a total of 16GB RAM being used by all processes, leaving 16GB memory free for use.
I have come to think that either JRockit is failing and throwing the exception without a good reason, or the message displayed is wrong and it is not letting me find the right cause of the issue we are facing.
Any kind of advice will be appreciated.

Hello,
I am running into a similar issue with Jrockit 28.2.3. Following is the stacktrace:

  • Issue in Deploying application in Weblogic 10 3 3 + Oracle JRockit(R) R28.1

    Hi
    I have Weblogic 10 3 3 with Oracle JRockit(R) R28.1.0-123-138454-1.6.0_20-20101014-1350-linux-ia32 as my JVM on my Linux box.
    When I deploy my application and starts it, app goes to New state and my Managed servers (on which I deploy my app) are forcefully shutdown.
    I am building my application using Oracle JRockit(R) (build R28.1.0-123-138454-1.6.0_20-20101014-1351-windows-ia32
    Below is the complete dump I get once my servers are forcefully shutdown
    It will great if any one could throw light on what is happening

    Hi
    I have Weblogic 10 3 3 with Oracle JRockit(R) R28.1.0-123-138454-1.6.0_20-20101014-1350-linux-ia32 as my JVM on my Linux box.
    When I deploy my application and starts it, app goes to New state and my Managed servers (on which I deploy my app) are forcefully shutdown.
    I am building my application using Oracle JRockit(R) (build R28.1.0-123-138454-1.6.0_20-20101014-1351-windows-ia32
    Below is the complete dump I get once my servers are forcefully shutdown
    It will great if any one could throw light on what is happening

  • Remote Connection Issue in Oracle JRockit

    Hi,
    I Tried configuring Jrockit and integrating weblogic server with it.
    I was successfull in monitoring the locally deployed app through integrated weblogic in JRMC 4.0.
    Please suggest if the following steps mentioned are proper or not.
    1) Installed JRMC 4.0 .
    2. Configured in default domain/bin folder of Weblogic server setDomainEnv.cmd as follows:-(Configuring oracle Jrockit in Weblogic since i have to use Jrockit JVM instead of Sun JDK Hot Spot)
    set BEA_JAVA_HOME=C:\Program Files\Java\jrmc-4.0.0-1.6.0
    set SUN_JAVA_HOME=D:\Oracle\Middleware\jdk160_18
    if "%JAVA_VENDOR%"=="Oracle" (
    set JAVA_HOME=%BEA_JAVA_HOME%
    ) else (
    if "%JAVA_VENDOR%"=="Sun" (
    set JAVA_HOME=%SUN_JAVA_HOME%
    ) else (
    set JAVA_VENDOR=Oracle
    set JAVA_HOME=C:\Program Files\Java\jrmc-4.0.0-1.6.0
    3.Inturn i modified Java_Options in my local weblogic server startWebLogic.cmd and Remote weblogic server startWebLogic.cmd as follows:-
    Local weblogic server startWebLogic.cmd :-
    set SAVE_JAVA_OPTIONS="-Djava.rmi.server.hostname=ZSLW521 -Xmanagement:ssl=false,authenticate=false,port=7091,autodiscovery=true"
    export JAVA_OPTIONS
    Remote weblogic server startWebLogic.cmd :-
    set SAVE_JAVA_OPTIONS="-Djava.rmi.server.hostname=ZSLW577 -Xmanagement:ssl=false,authenticate=false,port=7091,autodiscovery=true"
    export JAVA_OPTIONS
    4. My Oracle Jrockit Start parameters are as follows:-
    C:\Program Files\Java\jrmc-4.0.0-1.6.0\bin>java -Xmanagement:port=7091,ssl=false,authenticate=false,autodiscovery=true
    and even i am getting the status as follows in command prompt:
    [INFO ][mgmnt ] Remote JMX connector started at address zslw577:7091
    [INFO ][mgmnt ] Local JMX connector started
    [INFO ][mgmnt ] JDP autodiscovery started at address 232.192.1.212:7095
    Iin jrmc4.0 UI i am getting JDP (JRockit Discovered protocal)as follows:-
    1. Discovered --> JDP --> zslw577:zsl.local and
    zslw51
    2.But the Problem is that in the tabbed menu
    Discovered-->LOACL-->Getting Local JRockit Weblogic server Instance and Not Remote Server Weblogic Server Instance
    is when i am trying to establish a connection :-
    HOST:zslw521
    PORT:7091
    1.And testing the connection giving me : Unable to Connect
    Even If I want To test The JDP of Remote and Local JVM Instances by right clicking and selecting the option of START CONSOLE
    Could not open Management Console for zslw577.zsl.local.

    I had the same problem, but adding:
    -Djava.rmi.server.hostname=my_hostname
    to the remote WebLogic Server start script that I want to monitor solves the problem.
    In my case, my WLS runs on OEL 5, and I monitor it via JRMC (R28.0.0-679) on Windows XP):
    # Start JRockit MngSrv to enable JRMC monitoring:
    JR_XMNG="-Xmanagement:ssl=false,authenticate=false,port=7091,autodiscovery=true"
    export JR_XMNG
    JAVA_OPTIONS="-Djava.rmi.server.hostname=your_hostname ${JAVA_OPTIONS}"
    export JAVA_OPTIONS
    JAVA_OPTIONS="${JAVA_OPTIONS} ${JR_XMNG}"
    export JAVA_OPTIONS

  • JRockit R28 and XStream

    Hi,
    fyi: testing JRockit R28 we ran into a small compatibility issue - in R28 vendor name has change from BEA to Oracle and out xstream-based code will not work anymore.
    This patch "http://jira.codehaus.org/browse/XSTR-618" is solving this issue. Both, xstream 1.3 and 1.3.1 are affected.
    regards,
    makiey

    I opened an SR and got this clarified. There are separate downloads for the Java5 and Java6 versions of R27 and R28. If you have a support contract, log in, select "Patches & Updates" at the top of the screen, then select the "Product or Family (Advanced)" link. Product is "Oracle JRockit." Then select your desired release and platform.

  • The Oracle JRockit JVM is not supported by SAP JCo 3.0.5.

    Hello all,
    I am preparing our new Oracle Fusion Middleware platforms. So far we have been running BPEL 10.1.3.4.0 and we are going to build the 11g platform (WLS and SOA suite) in parallel.
    I have already installed WLS Server 10.3.3 and then SOA Suite + the SOA patchset bu selecting always Jrockit_160_17_R28.0.0-679.
    Now I am abaout to install the adapters and I red in the documentation
    http://download.oracle.com/docs/cd/E14571_01/doc.1111/e17054/intro.htm
    For supported JVM information that corresponds to each operating system, see the SAP Note #1077727 in the SAP Service Marketplace.
    Note:
    The Oracle JRockit JVM is not supported by SAP JCo 3.0.5.
    Is anybody aware of this? If it is valid, how could I achieve not to re-installa everything from scratch and select SUN JVM?
    Could I for example create a new Managed Server where I will explicity select SUN JVM to be installed for this instance?
    Best Regards,
    Loukas Rougkalas

    Please post your question to SOA forum. This forum is about WebLogic Connector Container.

  • Oracle JRockit Real Time 3.1.2 and weblogic?

    http://www.oracle.com/technology/software/products/jrockit/index.html". I go to the website, and find a software called: Oracle JRockit Real Time 3.1.2 for windows 64 bit. My question is: In order to let weblogic 9.2 works in windows 2003 R2 64 bit machine, SHOULD I MUST DOWNLOAD "Oracle JRockit Real Time 3.1.2 for windows 64 bit"? Or I don't need to download anything? Actually, I just download a file called jdk-6u18-windows-x64.exe. Please clear my question, thanks! One more thing, what is the functionality for Oracle JRockit Real Time 3.1.2? Is it a kind of JRE ?

    Hi,
    For more information on JRocket Real Time have a read of :- http://www.oracle.com/technology/products/jrockit/jrrt/index.html
    As far as I am aware you don't have to install the real time product you can installl the JRockit JVM and use that with Weblogic, I think newer version of JRocket come bundled with Real Time which is the JVM and monitoring and analysis tools. There are still standalone JRocket JVM installs available, you can get them from oracle edelivery.
    JRocket is a JVM but optimized for use with Weblogic, so you should get better overall performance.
    Cheers

    You are trying to receive a Datagram with an enormous byte array. The maximum size of a UDP datagram is 65535-28=65507 bytes, and the maximum practical size is 534 bytes.
    Best practice with UDP is to use a byte array one larger than the largest expected datagram, so you can detect truncations: if the size of the received datagram = the size of the byte array, you received an unexpectedly large message and it has probably been truncated.

    The Kerberos tools (kinit, klist, ktab) are not available in JREs on Linux and Solaris anymore. You can install a native kinit tool using the packaging manager on your system.

  • Welcome to the Oracle JRockit Real Time forum

    Bonjour "Etudiant from Tunisia",
    I'm not sure what you mean with "please give me the user/password".
    As far as I know there is no online OWB available where you could try out the product (if that is what you mean).
    If you would like to learn more about OWB, read online documentation or for instance the link that is provided in an earlier post in this thread.
    Otherwise simply install OWB and try it yourself. The Installation and Configuration Guide is clear enough even without much experience installing Oracle software, and the OWB User Guide provides some basic insight on working with OWB itself.
    Good luck, Patrick
    ps If people are still expecting what Igor mentioned when he started this forum ("Oracle Warehouse Builder (OWB) product management and development will monitor the discussion forum on regular basis"), don't count on it; fortunately the product itself has been around long enough now, there are quite some users that can share usable insights and/or drop some useful lines on the new threads... ;-)

    Should I need to increase -XX:MaxClassBlockMemory to 75M. If so, how should I do it, I am unaware of how I can set the values? My Planning server has 136GB Ram and 18 Cores.
    Thanks,
    hyperionEPM

    The issue was related to the heap size being too much and as a result the Class block memory was not getting enough memory. I think we can make a use of -XXCompressedRefs:32 parameter in the Java start up to allow the heap size to increase till 32 Gb.

  • Excesive CPU usage - java process OBI related

    Hola a todos,
    We have installed OBIEE 11.1.1.5 in a virtual machine (a clean one, just DB and OBI) and since a few weeks we've noticed perfomance issues. There is a java.exe process running with 30 - 50% CPU usage and if we stop it, OBIEE stops working as well, so we think it may be related, but we dont have any further clues.
    Has anybody dealt with something liket his before or does anyone know if there's a log where we could check this?
    Thanks in advance.

    Tuning
    Whether its a 64 bit or 32 bit of SUN or Jrocket ,
    Please increase the heap size parameters to Xms & Xmx to atleast2048 (min and max to atleast) 2GB
    Below were the comments from Oracle Support
    Best Practices Guide for Tuning Oracle® Business Intelligence Enterprise Edition
    In JRockit JVM (R28), the heap grows faster than before. The JVM also ensures that the heap size grows up to the maximum Java heap size (-Xmx) before an OutOfMemory error is thrown. In addition, the default value of the -Xmx option is changed from 1 GB to 3 GB on 64-bit OS. Note the JRockit JVM auto shrinks the heap if it is unused or if other applications require more physical memory.
    Note: It is recommended to use the default garbage collection mode i.e. -Xgc:throughput. Also
    large heap reduces the garbage collection frequency and fragmentation, improving the throughput
    of the application; however, a large heap increases the memory footprint of the Java process.
    *Warning: Make sure you have enough physical memory allocated / available on 64bit servers and then use the above settings as a starting point, and after load testing, adjust as needed. For a stable / an even performance over time, you should set the initial heap size (- Xms) to the same value as the maximum heap size (-Xmx).
    Common JRockit JVM issues seen with BI (i.e. bi_server1) managed
    servers:
    Startup Times Take Longer When Using JRockit JVM Versus Sun JVM: The Oracle® JRockit JVM is by default optimized for server use, which means that the startup times can be longer in favor of high performance as soon as the application is up and running. Moreover, as the application runs, the JRockit JVM optimizes frequently called methods, improving the performance further.
    When you run the JRockit JVM on a 64-bit system with a heap size less than 4 GB, if native OutOfMemory errors occurs despite memory being available only then add the parameter -XXcompressedRefs:size=32GB in JVM startup options to enable heap to grow up to 32 GB heap (practical limit of 25 GB). This will fix the issue native OutOfMemory errors. Moreover heap size still be restricted till the limits defined using -Xmx only benefit would be your heap will get the capability to grow beyond 4 GB up to 25 GB due to increase in size of pointer to
    32 bit address.
    On Oracle Solaris SPARC, due to the way classblock memory is reserved,Oracle® JRockit (R28) might occasionally run out of memory when a large number of classes are loaded (in the order of 100000).Workaround: The default value of -XX:MaxClassBlockMemory=50 MB, and a reasonable value is around 75 MB.
    By design Oracle® JRockit will often use more memory than Sun JVM because JRockit compiles everything and is optimized for being a server-side JVM. So if
    your customer have limited resources (i.e. CPU, memory) then it is recommended to experiment with switching to the Sun JVM which should save some system resources, but customer really should consider to do a performance tuning and sizing exercise, and determine if they have sufficient memory / CPU’s to support their requirements.
    It is important to keep Oracle® JRockit R28.1.x up to date with latest fix release because the latest release provide fixes for security vulnerabilities, performance,
    and other improvements of the Oracle® JRockit R28.1.x
    Tuning 64bit Sun JVM
    suggested
    Minimum heap -Xms2048m Maximum heap -Xmx2048m
    Minimum permanent generation heap -XX:PermSize=512m Maximum permanent generation heap -XX:MaxPermSize=512m
    I'm not sure from where I've copied but save the same in text file.

    what's wrong in my configuration ?
    Edited by: 944618 on 2012-7-5 上午4:26

    I would add the jvm flag -showversion next to the -Xgc:pausetime flag, so you will see which JVM you're actually running.
    Also, the following part of your post is a bit inconsistent, which jvm flag are you actally using?
    "but,but,i use -Xgc:pausetime in my tomcat7;tomcat startup error:
    The configuration of the JVM attributes in Tomcat in catalina.sh

    the error info:
    [ERROR] Argument error: -Xgc:pausetime"
    The error output you posted looks like the error you would get from a R27 version of JRockit.
