How should I interpret java thread dumps?

• How to get lots of thread dump without killing-3?

  I am trying to solve a problem of thread blocked involving multiple threads external middleware, it blocks what locks being help in the middleware client libraries. Unfortunately in the environment, most people (including those available at 2:00 when offshore is testing) have access to Linux for the JVM WebLogic user ID, so they cannot issue a kill-3.
  
  Thread through the console (and WLST) dumps are not enough, because they are not full thread dumps, that is, they do not show what threads hold locks (they show only what are threads waiting for locks) - that is, they contain no lines like:
  
  -locked (an oracle.jdbc.driver.T4CConnection) < 0x0000000798fc9e88 >
  
  Is it possible to achieve this programmatically or otherwise, far from being able to issue a sigquit (kill-3) to the same user WebLogic runs under?
  
  WebLogic 10.3.5, Sun/Oracle Java 1.6.0_33 (64-bit) 5.6 RHEL. And, FWIW, SonicMQ 8.5 - our threads WebLogic are apparently stuck trying to write off of a TX of XA.

  Hi Steve,.

  There is a WebLogic Admin command to take dump thread. It is obsolete, but you can still use it.

• How to call javafx scene for a pure java thread

  I have a server as a thread that starts when the application is running, it will listen to a client, when TI receives a message from the client a scene to appear alongside server.
  
  I get error not a fx thread when I call pure java thread.
  
  need help as soon as possible.

  I think that what you are looking for is the Platform.runLater () function.

  This will allow you to give a Runnable which is scheduled on the thread of FX. Put the code to display the scene and it should work.

  For example:

  Platform.runLater(new Runnable() {
    public void run() {
      // the code here to show the Scene
    }
  });
  

• Collect the Thread Dump using Script and live in the separate log file

  Legends of dear,
  
  I ask you to provide me with a few lines of useful guide to collect the Thread Dump using script on linux and redirect the output to a separate log file, but not the STDOUT file. If it is redirect to STDOUT then how to extract only the thread stack to a separate log file.
  
  I used
  ps - ef | grep java
  kill - 3 < pid > > > ss1_td.log
  
  but it does not provide the thread stack to the log file.
  
  Any aid operation would be appreciated a lot.

• Is there a way to see the files opened by java threads

  -environment-
  Java for 64-bit Server VM (build 1.5.0_19 - b02, mixed mode)
  Linux 2.6.9 - 78.0.5.ELsmp #1 SMP Wed Sep 24 12:40:24 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
  Xeon of Intel (r) CPU
  --------------------------
  
  Hi all
  
  I would like to know if, in the course of an outOfMemory, there are ways to:
  1. do you have a list of thread for the time (basically a thread dump)
  2. know the thread which lead to the OOM (even if the thread could well be the 'drop' leading to OOM)
  3. get a summary of the brief files on track to open by thread (basically a dump of the heap) use java.
  4. get a list of files opened by my thread
  
  Our application is regularly faced with outOfMemory (OOM) and I know that this sometimes load important file, so now I'm testing is the use of hprof (-agentlib:hprof = heap = sites, thread = y, depth = 2). Send "kill-3" on my java process creates a file containing a thread dump + memory usage. But it can't help me for question 2.
  
  Regarding question 4, I tried to establish a correlation between the hprof output + pstack + jstack, pmap, but I'm not the info I'm looking for (pstack, jstack do not show the address of open files)
  
  Finally, if this isn't the right forum for my question, please tell me where to post it.
  
  Thank you

  Have you tried - XX: + HeapDumpOnOutOfMemoryError?

  I would use a recent version of Java as Java 6 update 25.

  You can get a list of files opened by looking at/proc / {pid} /fd/ however you should never be allowed to open as many files as you run out of memory.

  If you use a Profiler, you can see that the son made at some point, and where objects are allocated.

  I don't think you can associate files with a wire.

• How can I add Java SE 8 of my browser

  I have a www.runthemodel.com/models/2006 application which requires Java to run 8. I have Java 8 is installed on my desktop. When can I access the site, I get a message 'a plugin is required to run the content. When can I access the site on my laptop, I am able to connect to the program without problem.
  Any suggestions

  To test whether Java is installed and enabled in Firefox, visit one of these Java test pages:

     Verify Java Version
     Verify Java Version (alternate)
  

  When you visit these pages, you will normally have to activate Java. How to enable Java on trusted sites, explains how. You can also see a prompt asking you to confirm that you want to run Java to Java security. This safety message isn't Java, Firefox. For more information, see the Java help page what should I do when I see a security prompt from Java?
  Activation of Java

  If Java doesn't work, make sure that the Java plugin is enabled in the Add-ons Manager tab:

     Click the menu button New Fx Menu and choose Add-ons. The Add-ons Manager tab will open.
     In the Add-ons Manager tab, select the Plugins panel.
     Click on the Java(TM) Platform plugin to select it.
     If Java is disabled, click on Never Activate to open its drop-down menu and select the option to activate Java. The recommended (default) option is Ask to Activate, which lets you run Java when prompted.
  

  Note: You only need to activate the "Java (TM) Platform" plugin, if it is disabled. The plugin "Java Deployment Toolkit" is used by Java developers to detect your version of Java and deploy their Java applications and does not need to be enabled for Java to work.
  Troubleshooting

  If Java is installed but does not work, try these solutions:
  Java plugin does not appear in the Add-ons Manager

  If the Java plugin does not appear in the add-on Manager, even if Java is installed, try each of the following values, one at a time and then reopen Firefox to see if that solves the problem:
  Delete the pluginreg.dat file

  With completely closed Firefox, delete (or rename) the file pluginreg.dat is located in the Firefox profile folder (it will be regenerated once you restart Firefox, but other plug-ins that you can have turned off will be activated). See re - initialize the plugins database to get detailed instructions.
  Ensure that Java is enabled in the Java Control Panel

  From Java 7, Java Control Panel includes the security option, 'Enable Java content in the browser', which is selected by default. If this option will prevent Java applets from running in any browser and the Java plugin will no longer appear in the Firefox Add-ons Manager. Make sure that the content for activate Java in the browser is selected in the Security tab of the Panel control Java. See this Java help page for more details.
  Make sure that the 32-bit version of Java is installed

  On 64-bit Windows, if you have the 64-bit version of Java installed, the Java plugin is available. Releases current Firefox are a 32-bit browser, and you need to install the 32-bit version of Java.
  Make sure that the plugin scanning is not disabled

  Mozilla browsers use the plugin scan to locate the plugins installed, so you must ensure that the preference of plugin.scan.plid.all has not been disabled:

     In the Location bar, type about:config and press Enter.
         The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise! to continue to the about:config page.
     Search for the preference plugin.scan.plid.all
     If it's been set to false, right-click on it and select "Reset".
  

  Uninstall if installed JavaFX

  In some cases, after upgrading from a version earlier than Java Java 7 Update 10 or higher, the plugin java (TM) Platform is no more detected. This can be caused by a conflict with Java and a stand-alone JavaFX installation that prevents the Java plugin to be properly registered. To solve the problem, uninstall JavaFX. For more information, see the java.com help page.
  Other solutions

  If Java is installed and enabled (see above) but does not work properly, try the following:
  Remove outdated Java plugin files

  Ensure that multiple versions of the java plugin (TM) Platform are not detected. For example, if 51 Java 7 update is installed, the java plugin (TM) Platform in the tab of the Add-ons Manager should be among the Java (TM) Platform SE 7 U51. If you see other versions of "Java (TM) Platform" listed, uninstall the older versions (see how can I uninstall Java on my Windows computer?) or otherwise remove manually (see manually uninstalling a plugin).
  Check for other software that may block Java

  Even if Java is installed and enabled in Firefox, it may be blocked by other software or Firefox Add-ons, for example:

     The ZoneAlarm Pro software firewall can block Java. For more information on enabling Java through this program, see the ZoneAlarm Pro forum.
  

     The NoScript extension for Firefox will block Java. For more information, see the NoScript FAQ.

• How should I prepare for El Capitan 10.11.2?

  Hi all

  As the title asks, how should I prepare for this upgrade?

  I had already installed El Capitan 10.11.0, but quickly returned to 10.10.5 after discovering several problems:

  1 (2 x 1 x POP, IMAP) e-mail accounts - problems with lack of mailboxes, mail lost, unable to send mail, etc.

  2. Time Machine backups were not held as scheduled when my iMac end of 2013 has been plugged into my ups APC.

  3. casual does not recognize my USB Superdrive.

  After the restoration of my old system of Time Machine, I followed several thread on these forums to see what others have experienced with the 10.11.2 release.

  My iMac does not have any third-party software with the exception of my HP ENVY 4502 print utility.

  How should other ensuring that Time Machine backs up current, I prepare for this facility to ensure that I do not lose important emails from my accounts {2 x iCould (IMAP) and Comcast (POP3) 1 x}?

  You know, honestly until that Apple's software team act together and reflection on the QUALITY rather than pretty flowers I'd wait for a few weeks to a month.  Or, at least until more people have put to date to see if there are problems.

  So, to answer your question, make sure you have at least 2 strong BACKUPS before you update.

  Hello

  Sign on support.oracle.com and look for:
  (1) problem: 100% use of the processor because of blocked Threads observed with Apache Xml beans [ID 1307201.1]
  (2) NOTE: 977591.1 -Thread blocked problem in Oracle WebLogic Server using Apache XMLBeans v2.3

  These two looks like your problem. You probably need to update the library XMLBeans.

• What ' s a weblogic thread dump format?

  Hello
  
  I have a question for thread dump in Weblogic.
  
  When I see this message; java.lang.Thread.State: EXECUTABLE; my understanding is that the thread is running.
  Example:
  "Connection TCP RMI 3025 - 10.30.73.39"-wire t@278
  java.lang.Thread.State: EXECUTABLE
  at java.net.SocketInputStream.socketRead0 (Native Method)
  at java.net.SocketInputStream.read(SocketInputStream.java:129)
  at java.io.BufferedInputStream.fill(BufferedInputStream.java:218)
  at java.io.BufferedInputStream.read(BufferedInputStream.java:237)
  -locked < 235738ef > (a java.io.BufferedInputStream)
  == > this thread runs and reads data...
  
  Now, what is a '[ACTIVE]' thread in Weblogic? my opinion is that it is also a running thread. Am I wrong?
  
  If both threads are running, why one is not also maraked as "[ACTIVE] '?
  
  Another question, what ' s the difference between these two threads?

  Thanks for your help

  Hello

  [ACTIVE] [EVE] are States that Weblogic assigns to its internal nets.

  Most of the time, you will see discussions (waitForRequest) pending pending because they do nothing.

  Discussions in the way ASSETS Weblogic kernel assigned a request and that request is in progress.

  I saw in some Threads in Thread dump in ACTIVE State, even if they expect a request so not 100% compatible. I worry too much on this subject.

  The part of the key to analysis is to analyze the Stack Trace of the Thread and the native state of Thread (RUNNABLE, WAITING), those are your real indicators if the Thread is waiting for a query or really stuck a request for treatment.

  -The first line will also give you the current Thread action (waiting to be warned, blocked / stuck on a monitor, computer science etc..)
  -The Stack Trace will also give you specify if the Thread is waiting to process a query (free Thread) or a real application or the task of Weblogic internal treatment

  Kind regards

• How to get the Java instance variable in JSP custom

  Hello
  
  I decided to list some simple Java classes to use as instance variables. This should make it easier to do things with them in a JSP page since I know exactly what kind they are.
  
  My question is how to get my Java instance in the JSP page variable - I a screenflow with an Interactive component in what I would normally choose BPM interactive object call, but this allows BPM object instance variables not Java ones. So how can I associate my JSP custom?
  
  Thank you
  
  Neil

  In my view, that there must be a BPMObject that is passed into a JSP page. My suggestion would be to build a BPMObject as a "viewObject" with only the values you need and in the BPMObject constructor, load the java class data. And then possibly have a 'storeToJavaObj' method, you call after the JSP, which then stores the data to your java class if you wish.

  HTH...

  This is very unusual.  Two thoughts come to mind.

  1. Your storage space is too full?  Check the settings > general > storage & use iCloud > manage storage (in storage).  Make sure you have at least 10% (hopefully more than 15%) of total storage of your iPhone for free.
  2. Use iTunes (you must use the current version - 12.5.1, as this is the only version supporting iOS 10) to upgrade.  See 'Your device via iTunes update' here: update the iOS on your iPhone, iPad or iPod touch - Apple Support software

• How can I allow Java 7.55 on Firefox 29?

  In collaboration with a training site that requires Java. I have the latest version of Java Runtime (55-7), Firefox blocks seem to note specifically on built 25 to 44, but maybe later built as well. My build is blocked.
  I tried a section which describes the release on a trusted site, but can't find how to get the Java icon in the access address bar unlock options.
  Compaq Presario running XP, 2.2 GB of memory, 500 GB disk space, connection ADSL2 + provider.
  The basic problem is the delay and distortion of sounds in games designed to measure the speed of reflex, and blocked Java is the only incompatibility that I can find the published requirements.

  Thank you, Alice. I've been chasing the wrong Hare. In view of the Java plugin platform, it is allowed, and so my core of sound distortion problem is not to do with plugins and maybe not Mozilla. Big step forward.
