• Oracle JRockit R28.2.2. OutOfMemoryError: classblock award

  Hi people,
  
  Well, we have a production Weblogic on Oracle JRockit Virtual Machine environment. The problem is that we are trying to avoid an 'exception' OutOfMemoryError is thrown every day by a SOA managed server, which causes a failure and stop the managed server that must then be restarted, causing interruptions of service applications.
  
  Platform:
  64 bit of Windows Server 2008 R2 Standard. 32 GB OF RAM
  
  Products:
  Oracle JRockit R28.2.2
  Oracle Weblogic Server 10.3.2
  Oracle SOA and BPM Suite 11 g R1 11.1.1.5 offers Pack
  Oracle 11g 11.1.1.5 bus services
  
  
  The error message is the following:
  
  means: classblock award, 110787528 load, 84224K footprint, in check_alloc (src/jvm/model/classload/classalloc.c:215).
  
  Attempt to allocate 7G bytes
  
  It is not enough native memory for the Java
  Execution environment to continue.
  
  Possible reasons:
  The system is out of physical space RAM or swap
  In 32-bit mode, the process size limit has been hit
  
  Possible solutions:
  Reduce the memory load on the system
  Increase the physical space of memory or swap
  Check if the swap backing store is full
  Use Java 64-bit on a 64 bit OS
  Decrease the Java heap size (-Xmx /-Xms)
  Reduce the number of Java threads
  Decrease for the Java thread stack size (-Xss)
  Disable the compressed references (-XXcompressedRefs = false)
  
  
  Here are the conclusions that I made on this problem:
  
  -It is clearly indicated in the error message that is not a matter of size of the Java heap since this kind of errors usually look like: (Java Heap Space, getNewTLA, etc...) and the message makes clear: "memory is insufficient native to Java runtime environment continue. In addition, the MissionControl records show that the heap is constantly collected garbage and there is no memory leaks.
  -The size of the process is about 10 GB (7 GB Heap Size and 4 GB) memory native platform consists of a 64-bit Windows Server 2008 with 32GB, so it is neither a "process size limit question."
  -According to this, it would be clear that the problem is that "the system is out of space RAM or physical swap", but this is not true either, because the system has a paging file max 48 GB (this is actually useful) and above all, the system has 16 GB of RAM used by all processes leaving the 16 GB of free memory for use.
  I came to think that either JRockit is default and throw the exception without good reason, or the message displayed is wrong and is not let me find the right the cause of the issue we face.
  
  Any kind of advice is appreciated.

  Hi Alain,

  As Mike mentioned earlier, try to increase

  -XX: MaxClassBlockMemory 75 m.

  Use the following option.

  -XX: + UnlockDiagnosticVMOptions - XX: MaxClassBlockMemory = 75M

• Oracle abandons JRockit?

  In the JRockit download page, I noticed that he was moved to the section archives

  Family JRockit download page

  Does this mean that oracle JRockit abandon?

  There is no more public releases JRockit, R28.2.7 is the last (accessible from the page of archive) public. Access to later versions is subject to support contract.

  (It wouldn't hurt if the JRockit download page mentioned this, I think)

• JRockit Mission Control (jrmc) - access Web

  Hi experts,
  
  I JRockit installed on GNU / Linux (Suse SLES10 Linux) x 86-64. The demand must be able to provide a url outside no Linux users who can access jrmc via Internet Explorer on their laptops. My questions are:
  
  1 is it possible?
  2. If so, is there a special configuration that I need to do? If Yes, can someone please provide highleve steps
  
  Thank you

  External users must install JRMC in order to connect.

  They have to download the same version of the JRockit JDK you are using (or a newer version)
  Run \bin\jrmc

• How to use - XexitOnOutOfMemory?

  Hello

  I build new WebLogic for ADF running servers on "jrockit - jdk1.6.0_45 - R28.2.7 - 4.1.0. We have a problem in which we work on where we get OutOfMemory errors. Nevertheless,.

  Based on this document: Command-Line Options-XX , there is a parameter to say jrockit jvm to shutdown when there is an OutOfMemory error ('-XXexitOnOutOfMemory"). This setting would be perfect, because instead leave WebLogic in a State of suspension, he would stop and Manager of the nodes it will boot just straight up.

  However, when I add the setting to my WebLogic startup settings ("-XXexitOnOutOfMemory"), JRockit said that this argument is an invalid argument.

  How can I implement this?

  Thank you

  Gavin

  I found this quite amusing question because there are oracle documentation contradictory on this point - however the correct documentation has helped

  JRockit R28 documentation: http://docs.oracle.com/cd/E15289_01/doc.40/e15062/optionxx.htm#BABCDAIB

  By the documentation it says to put "-XX: + ExitOnOutOfMemoryError. To implement in my scripts worked like a charm.

• Interpret the hot methods table

  Hi all

  TL; DR: What are the causes some methods appear more frequently than others in the table in point hot method?

  I use the Mission control with JDK 64 bit for Linux 1.7.0_40.  Sorry, it's a bit long.

  I have a problem of unusual performance where some lots turns very quickly (< 10 minutes) after an app server restart but almost always of 80-90 minutes on the following nights.  The work of copying the data from Teradata to Oracle by running a single JDBC query against Teradata, read the records of ~ 50 k and engraving to Oracle in batches of ~ 2000 in parallel with the consistency of work Manager and repeating up to about 15 m rows have been processed.  This used to run constantly fast under 32-bit JRockit R28.x (Java 5).

  I realized many recordings of flight of the lots.  What jumps out at me is the gaps between the read the events of Teradata.  The event log shows this sequence for the main batch job thread:

  socket read Teradata event (15-20 ms constantly)

  method of profiling of events read the result set (total duration varies from night to night)

  socket read Teradata event (15-20 ms constantly)

  method of profiling of events read the result set (total duration varies from night to night)

  socket read Teradata event (15-20 ms constantly)

  method of profiling of events read the result set (total duration varies from night to night)

  events pending for the job manager complete queue Java monitor (< 500 ms constantly)

  repeat...

  There are usually 3 socket read groups events between calls to the job manager.  If the batch is running quickly, there are very small gaps between the readings of socket with the method very little profiling events (100ms).  If it works in the range of 30 minutes (rarely), these gaps are about 1 second.  If it works in the range of 90 minutes (often), these gaps are about 3 seconds.  In other words, it takes more time to read the results out of the resultset buffer it does for them to insert Oracle!  The only thing attracted my attention since the recording of the flight, is that there are a lot of events in this profiling method.  It seems that the methods of reading data from the result set, resultSet.getString (int) for example, take more time on some nights than others.  How would that be?

  I've already spent the result based on the name of the calls defined as resultSet.getString (name) of calls based on the post as resultSet.getString (int) based on what previous records (and my analysis of the decompiled Teradata driver) showed.  Methods hot look a little different now, but the performance is the same.

  The server has 4 modern processors, its use is about 20 to 30%, debit GC is far superior to 99%.

  Thank you

  John

  This proved be caused by the cache code to fill.  Once we have activated PrintCompilation and had Wily monitor the size of the cache in code, it was obvious.  We have quadrupled our cache of code size and now actually use about 80-90 MB.  25 k methods are compiled.  This particular step of our lots went from 90 minutes to 7.  Overall, the CPU usage has been reduced by half.  Not bad.

• Newbie: What version of WL is required to use the experimental WL plugins?

  I managed 10.3.5 installed and connected on jrockit r28, but get with 10.3.2 on r28. The WLDFDiagnosticVolume property is not available on the managed nodes, for example. I am able to connect to 10.3.2 and see the JRockit JMX counters very well, but I'm looking for WebLogic JDBC WLDF counters in particular. They are not there. Is there a workaround for different versions of WL?
  
  And for kickers, my installation of Mission JR control seems to have developed some bits of rust, too. I was able to run "Help\Install Plug-ins.... (Not supported) "once and installed all sorts of things. Now, however, it will not work. He complains, he does not feature on the selected site and told me to choose another.
  
  Thank you for any advice, including links to work to help the docs. :-)

  WLDFDiagnosticVolume is available from WLS10.3.3, this is the reason why you can't find this property in WLS10.3.2
  We have not all similar to WLS10.3.2 properties as JFR (registration of flight JRockit) is not integrated into the framework of WebLogic WLDF before WLS10.3.2
  The property and features that use this property are all only introduced in WLS10.3.3, that is, this property is a similar property will not help (don't not mandatory) in WLS10.3.2 like no collection will use

  In addition, in order to use JRockitR28.0 for versions older than WLS10.3.3, that is, WLS10.3.2, WLS9.2MP4, etc., we would need to apply patch #9884941
  Please do understand that this patch is only to fix some known issues with JRockitR28 only product WLS. This patch will not present the features of integration with JFR WLDF (WLDFDiagnosticVolume still is not available with this patch). Integration with JFR WLDF is a new feature that is available from WLS10.3.3.
  Once again, it is only necessary if you want to run using JRockitR28.x WLS10.3.2

  About plug-ins, I have personally not tried.
  But it seems that you have installed all the plug-ins that were available on the test site. I think that you are not any other plug-ins that are available for to install you.

• JDK for P6v8

  In the documentation, it is said that the necessary version of JRockit is "JRockit to Java SE6 (1.6.0_20) R20
  
  The JRockit version that comes in the V20499-01 is:
  
  JRockit R28, build 1.6.0.17 - b04
  
  Is this the right version? I have problems with my installation. The PB is improved and the Windows client works very well. I installed WebLogic 11 GR 1 material.
  
  When I run the wizard from the Configuration of Weblogic and go through the steps to set up the new field of P6, quite well, and then at the end I get the message:
  
  "A fatal error has occurred. This application will end."
  
  
  In the newspapers, I see this:
  
  2010-11-18 11:11:46, 243 ERROR [Thread-4] com.oracle.cie.common.util.CreateShortcut - CreateShortcut: ERROR: creation: start the Server Admin for Weblogic Server Domain.lnk
  java.lang.UnsatisfiedLinkError: expects an absolute path to the library: jni_winx64
  at java.lang.Runtime.load0(Runtime.java:767)
  
  I'm guessing it could have to do with the version of java, but am not sure. Note that domain records are created very well, but there is no shortcuts to my user P6 project in Weblogic.
  
  All this experience? It was going so well...
  
  See you soon,.

  I worked through this. The version of JRockit communicated in the x 64 Windows media pack is not correct. I got Sun Javsa 1.6.0_22 and re-installed Weblogic. Now I can add domains without problem. I also downloaded JRockit R28 1.6.0_22. But the Sun downloaded and installed first version, that's what I used.

  Like Daniel, I also used the Sun JDK 1.6.0_22 and had no problems.

• IOM works on jrockit - jdk1.6.0_45 - R28.2.7 - 4.1.0 - ssl_error_no_cypher_overlap

  Hello

  We have IOM works on jrockit - jdk1.6.0_45 - R28.2.7 - 4.1.0

  when trying to connect to http://Server:14000 / identity -it works well

  When you try to connect tos-http: //server:14001/identity

  with the latest version of Firefox

  We get error

  "no common encryption algorithm. "Error code: ssl_error_no_cypher_overlap.

  This means that we must again JDK? kind of 1.7 or 1.8?

  Firefox and other browsers are now apply the strictest encryption which means TLS1.1 +.

  There are solutions to allow browsers to use the old protocols less secure, but workaround solutions will be only temporary, as the next versions browsers is likely to have these disabled compatibility modes.

  Unfortunately, jrockit is abandoned, so it will be not updated for more secure implementations of TLS.

  Finally, you must update the IOM to make JDK supported TLS1.1 and TLS1.2, then you will want to get that rather sooner than later.

  Default JDK 1.8 is TLS1.2, but its not yet supported for IOM, the best you can do right now is upgrading to JDK 1.7 which is supported and who can do TLS 1.1 and TLS 1.2

• No javaw in jrockit - jdk1.6.0_33 - R28.2.4 - 4.1.0

  Hi I am using for my eclipse jrockit jvm. The documentation tells me I must point to javaw as the jvm in the eclipse.ini file. I installed jrockit - jdk1.6.0_33 - R28.2.4 - 4.1.0 and jrockit - jdk1.6.0_37 - R28.2.5 - 4.1.0 on my linux 5u7 64 bit installation of oracle, but it is not javaw in installation of jrockit bin.
  The two 64-bit JDK, I tested it with java-version.
  Any idea what goes wrong?
  
  Concerning
  Edmund

  Hello

  This javaw.exe is used to for Java Web start.

  If you see clearly in the doc to use use the option - vm as javaw under jre/bin folder.

  If you can't find them, you can use java.exe.

  This reference is only to the JVM option to use for the IDE.

  So we can check for the why this javaw.exe is not exists by means of Oracle support so that you can use java.exe to run your IDE.

  Hope that if responds to your request.

  Kind regards

• Why JRockit Realtime does not appear in jrockit - jdk1.6.0_33 - R28.2.4 - 4.1.0

  I can't find the new version 4.0/4.1 of JRockit RealTime in the Installation of JRockit or separated anywhere. Anyone know where it is?

  Kalyan is correct, you must use

  It's all in the same JDK (and thus had time real JRockit is just a product name for JDK with a certain indicator of JRockit jvm)

  Any idea what goes wrong?

  It looks like your user settings might cause problems for some reason any. Try to rename your file from c:\users\aagashe\.jrmc to old.jrmc (or something else if you want), then start JRMC and see if it works better.
