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.

  • 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.

  • Kinit not found in JRockit R28

    Hi,
    I am following the documentation on setting up Kerberos authentication for WebLogic (http://download.oracle.com/docs/cd/E14571_01/web.1111/e13707/sso.htm#i1101993).
    In the documentation, it mentions kinit is available in JRE. But in my environment, I could not find it. Does anyone have any idea?
    I am using JRockit version jrockit-jdk1.6.0_26-R28.1.4-4.0.1 (linux x86_64).
    Thank you very much.
    Regards,
    tim

    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.

  • Coherence and XStream

    Is there any built in way to use XStream when serializing pojo's that are not serializable?
         Thanks,
         Zach

    Hi Zach,
         the problem lies in XStream relying on the serialized class not implementing java.io.Externalizable, but using the default serialization algorithm to be able to name child elements properly.
         XmlBean on the other hand implements Externalizable, and uses a serialization format which does not store field names at all (which would not be suppliable at all).
         There are good and bad things in this.
         XStream would most probably be able to serialize and deserialize XmlBean instances, only they would not be pretty printed when in XML format.
         Bad thing is if you rely on the attribute names being there, then you are out of luck. Also using Externalizable ties you to one specific version of the class, since the Externalizable implementation does not cater for different versions (different serialization formats for the same class). Stock Java serialization covers this problem to some degree.
         A possible solution would be to use a super class which does not implement Externalizable but implements ExternalizableLite (this would be used by Coherence but would not be used by xstream). Of course you would have to implement ExternalizableLite as you want.
         You can possibly implement it as delegating to xstream, although it would be much slower then implemented with a binary serialization format.
         Best regards,
         Robert

  • Looking for Performance Comparisons Between JRockit 6 and Sun Java SE 6

    Hello,
    Can someone point me to some performance comparisons (benchmarks, etc.) between the JRockit and Sun JVMs?
    Thanks in advance.

    Hi Ben.
    Before I send to to the SPEC sites (which can be a tad hard to parse) I must ask - What application or type of application are you interested in? The answer will vary a bit depending on what you need.

  • Difference betweeb JRockit JDK and SDK?

    Can somebody enlighten me the diff. above.
    Can the SDK be used together with the JBuilder SDK or Netbeans SDK?
    Thanks
    Francis

    Hi Francis,
    There is no difference between JDK and SDK in this context. SDK was used by Sun up to and including Java 1.4.2 to denominate the package consisting of the Java runtime (i.e. the JVM and the native libraries) and the developer tools (javac etc). They later switched to using JDK instead. JRockit follows the same convention.
    JRockit should work fine with any Java application, including IDEs like JBuilder or Netbeans. In the unlikely event that you run into problems, please contact us through the JRockit user forums here:

  • Daylight Savings Time 2007 and Jrockit JVM 1.4.2_04

    If I have applications running on WLS 8.1 SP2 with Jrockit JVM 1.4.2_04 on AS3, would the NEW Energy act of 2007 which resets the DST in march insteadt of April affect my JVM? If yes is there a patch?

    This fix is included in JRockit release R27.1 1.4.2_12 publically available from the download site.
    Read more: http://java.sun.com/developer/technicalArticles/Intl/USDST/
    BEA JRockit ports and includes the JDK from the Sun Java distribution, so things fixed in a Sun JDK is fixed in the corresponding BEA JDK.

  • 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

    Many bugs were reported for JVM crast at acGetOperand in JRockit R27.x
    But no bugs are reported exactly with the same stack trace.
    Regarding a workaround, the below stack is actually misleading us. It does not give us a clue about the reasons for the crash (whether it is happening due to concurrent GC or parallel GC or Compaction etc.), so we cannot really say what GC settings would avoid it.
    I recommend that we collect another textual dump if the crash occurs again and hope that the stack trace generated the next time will give us better insight into the root cause.
    Another suggestion would be to upgrade to R28.x

  • JRockit Installation fails on Redhat ES 4

    Hello there,
    I'm trying to install JRockit 1.4.2_05 on a Redhat ES4 system. I'm aware that this is a very new distribution, based on Fedora Core 3 which I see someone else has had problems with from a previous post.
    How can I tell the difference between an 8.1 SP5 and 8.1 SP4 release? I assume it's the _05 tag.
    I've seen a posting suggesting disabling the prelink facility, but is there a way to do that before the product is installed.

    The two cases I know about where running on RHES4 should be problematic are:
    1. You have prelink enabled.
    2. You are running a 64 bit RHES4 on AMD64. There are a couple of
    kernel bugs that makes JRockit crash and burn on this configuration, of
    which the known and identified ones are:

    Prelink is not a JRockit feature, it's a feature of the OS so it should be
    disabled before installing JRockit.
    There is no 8.1SP5 release of JRockit available. 8.1SP4 and J2SE 1.4.2_05
    is the same release. There is also a J2SE 5.0 release.

  • Why does JRockit updates lag behind Sun's?

    If I understand correctly, JRockit's class libraries are exactly the same as Sun's.
    Sun has already released update 8 for their 1.5.0 JRE, and JRockit is still at update 6, which means that the class library bugs fixed in update 7 and 8 are still present in JRockit.
    Why does JRockit updates lag behind Sun's? Judging by [url http://forums.bea.com/bea/message.jspa?messageID=600038245&tstart=0]this post, this lag is measured in months!
    Doesn't the VM development happen separate from the class libraries? It should be possible to release a new JRE with the "stable", QA'd JRockit VM and the newest class library (with all its bug fixes) within a week or so, instead of months.

    The class libraries are almost identical, correct. But a JDK update from Sun almost always contains changes in other components than just the class libraries. Some of these affect JRockit, in particular the native libraries (AWT, I/O, etc). Changes in the class libraries may cause performance or stability regressions.
    With every release of JRockit we certify our JDK (Sun classes + JRockit JVM + other components) on a large number of platforms. We did a count earlier this year and came up with around 80 different combinations of JDK level, OS and hardware that we have to test in every release by the end of this year.
    On these platforms we run a huge set of tests, including performance and stress tests. Even though a large part of our QA is automated, it is simply not possible to run everything in parallel so there is a certain minimum amount of time this certification takes. On top of that we have a set of time-consuming tests that have to be run manually.
    To summarize it is simply not possible to do this without some lag. And JRockit has a much quicker uptake than almost all other 3rd party JDK providers (many of them with JVMs based on Sun HotSpot). One example is that it took IBM almost 18 months to get their first J2SE 5.0 implementation out of the door.

  • How Can I get a HeapDump file in JRockit R26.3 or latter version

    I had tried "-Djrockit.oomdiagnostics.filename=oom.txt" arg,but it didn't work.
    how can i get a heapdump file in JRockit R26.3 or latter version ?
    I can only get the under infomation by using a ctrlhandler.act file.
