Error in a replicated Cache object

Hello
I'm under a single node for consistency with replicated cache. But when I try to add an object to it, I get the exception below. However, I get this error while doing the same thing in a distributed cache. Can someone please tell me what I do wrong here.

By default, it should have used FIXED unit-calculator. But look at the track seems that your replicated cache used BINARY as unit-calculator.

Could you try add FIXED in your configuration of cache for the cache to replicate.
Or try just insert an object (the key and value) that implement binary.

Check the part of the unit calculator on this link

    Hi Eric,.

    the replicated cache maintains the Java objects and returns them as they are, until a code changes the cache entry.

    What you see is the result of retrievalOne and retrievalTwo is the same object, if there is no change after the first call to the get() method.

    In addition, it is not only your thread may have a reference to this object but the other wires in the same JVM, too.

    This is why the objects returned by a replicated cache, near cache or local cache are not safe to be changed, you should put new objects in the cache of the key even with cache.put ().

  • Failed to get the objects displayed in the 3d element when I select the form replicator &gt; 3D object

    I was watching a tutorial on how to use the replicator forms to make a 3d object outside slot a particular form. I selects two primitive shapes and set one on the table Replicator and other particles of the atom. When I open my scene and change my form replicator 3D object disappear all my forms. I couldn't find anything on the internet about this problem yet and this is the only mistake (if it is not a user error) that I have ever met in the 3d element. Thanks in advance.

    If you have any questions about element plugin 3D video Copilot, I recommend to ask on the video Copilot site in forum 3D of the element:

  • Replicated Caches and POF not yet fully established in 3.4.1 / 3.4p2

    Hello

    Replicated systems with separate PofSerializers still do not work for us in line 3.4.1b407 or 3.4b405p2.

    We use a system replicated with a custom serializer component (a ConfigurablePofContext). At startup, the associated replicated plan service seems to load the ConfigurablePofContext but there is no attempt to use the PofSerializers specified in the XML configuration. Of course change our business objects to implement PortableObject directly not work around the problem.

    Anyone have any better ideas? Everyone's bored with PofSerializers?

    Thank you
    Tim

    Hi Tim,.

    Could you tell me how you run your test? ... how many knots, etc...

    If I don't just have your TestMain so I don't see your called PofSerializer. This is because the data takes place locally in the form of the object in the replicated cache and should never be serialized unless it needs to be replicated to another node. If I start several knots then I see your called TestValueSerializer. Could this be what you see?

    "The ' java.lang.IllegalArgumentException: resource is not serializable" is certainly an issue and I will open a topic for it. Of course, you can work around this by making your Serializable object.

    Let me know...

    Thank you
    Tom

  • I get a JavaScript Application error: "setTimeout" called on an object that does not implement the interface Window for Firefox.

    I get a pop up box with the message: Application JavaScript error: "setTimeout" called on an object that does not implement the interface Window for Firefox.

    But it seems to appear when I go to Amazon.com. Then he opens with this message and the OK option? But as fast as I can click OK, another box appears. After all a half dozen, she disappears - until what I move to another part of Amazon! I uninstalled - reinstalled and then - Firefox and BA. I do not understand this!

    (And of course, there is always the possibility that it is not only attacking me on Amazon... There may be a lot of other sites that also trigger, and I just haven't been there yet.)

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • In Firefox 29,0 and above, click on the menu button

      click Help

      then select restart with disabled modules.

    • In previous versions of Firefox, click on the Firefox button in the upper left of the Firefox window and click help (or click on help in the Menu bar, if you do not have a Firefox button) and click on restart with disabled modules.

    If Firefox is not running, you can start Firefox in Mode safe mode as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • Permission error - impossible to enumerate the objects in the container. Access is denied.

    I'm changing my library to my current user permissions and although some of my files are fine, a bunch of them throw the error message: "Permission error - impossible to enumerate the objects in the container. Access is denied. "When I try to change them. I can go in files and folders manually and edit them correctly, but it's a pain in the buttocks seen there are literally the * hundreds * of files that it is coming on.

    Any ideas on how to fix?

    I'm having the same problem, but try to include a file folder on a hard drive support separate than where I had installed windows 8. There are literally thousands of files. To your question:

    1 Yes

    2. Yes, and any other folder on the drive.

    3. to access the folder, I need permission!

    Thanks for your help, it is very frustrating.

    Here's how I solved my problem-
    1. on the root folder, right click, select Properties, select Security tab.
    2. click on advanced
    3. the window that opens should indicate to the current owner. Click on 'change '. Him "select user or group" pop up box appears.
    4. in the text box, type your user name (you should be an admin) and click the button "check names". Your name is replaced by the name of 'official' system (i.e., preceded by the name of the computer and the backslash).
    5. click on OK
    6. the box disappears, sending you back to the advanced security settings window.
    7. a new box appears under ownership, with the text 'Replace the owner of subcontainers and objects' check this box.
    8. I also selected the checkbox "Replace all entries authorization child object with entries permissions inheritable from this object", but I think that I had to run this twice - once with this checked and one without.
    9. make sure that 'everyone' appears in the Permission entries, if not, click Add. The same box that is displayed in step 4 appears again. Type everyone, click on "Check names", then "OK".
    9 valve apply

    I see also folder property can be changed to "everyone" - I have not tried to change all owners of my file to this, but doing so may eliminate the problem altogether if the drive is moved to another computer.

    I hope this helps someone, this problem and the lack of documentation has been quite aggravating.

    Today when I check one of the database alert log file, I get the message below

    Notification of memory: Cache object library loaded in SGA

    2607K heap size exceed the threshold of notification (2048K)


    I think it is the informational message and does not affect the database

    Please correct me if I'm wrong
