Has no recovery and OutOfMemory when using JMS with persistent JDBC Store

Hi again,

I fell right on the following problem:

My JMS queue works very well with a persistent store of JDBC. For a stress test, I stop the consumer and blocks the queue with lots of messages, each one about 1 MB. During the test, I can show messages in the console and I can check the amount of persistent messages by using command line access to the mysql db I currently use.

After about 3000 if they are sent to the queue of messages and the client was still running I stop the mysqld. Of course WLS began to throw exceptions and errors and the client stops with an exception that the message could not be persistet. Everything as expected so far.

As I restarted the mysqld WLS DID stop complaining, but when after a few minutes, I restarted my client to test to place messages in the queue, he immediately took the same exception as before, like the JDBC store was always down. I'm using WLS 9.2 MP3, I am aware that with MP1, there was a problem with that, but I was told that this has been fixed in MP3. Unfortunately I found no documentation to confirm this.

So I tried to restart the WLS instance to see if I could use the queue again after the start. When the reached the status server to START the boot process stopped. I thought that it was due to reading the messages in the persistent store and kept waiting. After awhile, I got classes OutOfMemoryErrors in MySQL-JConnector. It seems that WLS trying to load all messages ENTIRELY in memory when loading of the persistent store. This may not work when there are a lot of messages or a few very large companies in the store. So far, I wasn't able to access stored messages again. Can someone tell me why this happens and how I can prevent this? It is absolutely necessary to retrieve all messages after a closed server, even if the total size exceeds the available memory. After all, before, it was possible to see a few thousand messages to 1 MB each in the WLS console. I'm doing something wrong?

Cheers, Chris

Hi Chris,

WL JMS does load all messages at startup - but I'm pretty sure that it does not attempt to load them into memory at the same time. For the JDBC store, he travels a standard SQL cursor when it reads data. If MySQL is throwing an exception, it seems to me that there could be a problem with MySQL, or maybe the JDBC data source and/or the driver can be configured to make it less aggressive about filling the cursor with too many records at one time.

The JDBC store and services which are layers above it is not may not recover automatically from failures for a long time. Once they are low, they remain low. If you need bringing him upwards automatically, a way to proceed is to use the ability "reboot-in-place" of the automatic migration feature. The steps to enable this feature must target the JMS server and store a migratable target and configure migratable target. I think that the server can be part of a cluster for the migration of service feature (even if the cluster has only one server).

Also, if you happen to work for Oracle, you can email me directly (Tom Barnes).

Kind regards

Tom

  • Phone has stopped hanging and vibrating when I receive new e-mail

    My 6s phone hung recently arrested and vibrating when I get my new messages. I have reset all settings and also saved and restored the phone without success. All other apps work like alert messages, only problem with the mail application.

    Any help would be greatly appreciated.

    If your sounds and notifications are defined correctly and do not disturb is not on then try to reset the mail application.

    First close your Mail application completely from the window of the selector app by double clicking the Home button and drag the email preview pane up until it disappears from the display. You may need to search the mail pane covering scribbles to the left. Then go to settings > Mail, Contacts, calendar > find your e-mail provider and click on the account. On the next page, delete the account. Then perform a forced reboot. Hold down the home and Sleep/Wake buttons simultaneously for about 15-20 seconds , until the Apple logo appears. Then go to settings > mail... and to add the account.

  • Published Web site has components shift and disappear when the browser annotation scale.

    Hello world

    I am including a link to the published Web site, as well as including some screenshots of what looks like the question from my point of view. Just like a pre-emptive note: I had this problem before, and it was resolved by publishing a completely new site. I have saved the file under a new name, but also published the site under a new name and continue to encounter this problem. In addition, nothing is extended to the edge (for this thing of infinite width/length of browser).

    Thanks for any advice or assistance!

  • How can I change the default setting of font size and type when using e-mail?

    When sending an email, I have a default setting of the Arial font to 10 points. If I change what it comes down to Arial next time I use it. I don't know how to change the default setting.

    Hi Robin,

    What e-mail program you are using (name and version)? Windows Mail, Windows Live Mail, Outlook, a program that you access through your browser (and if yes, what name and version of the browser?) something else (and what version and/or year of this product)?

    What Version of Vista you are using (for example, 32-bit Vista Home Premium SP2 or other)?

    Thank you!

    P.S. I am pretty sure that the procedure is simple and can be done-, but it varies depending on whether you use, so I want to provide the information that is applicable to you.

    **********************************************************

    EDIT: Just a few alternatives which may help:

    If Windows Mail, go to Tools / Options / compose / font settings (ditto for fonts Signature if you use signatures) and change it to anything you want.  Save the changes and close Windows Mail, and then reopen it.  Your default sending policy should now be what you set with this configuration.

  • Picture in picture book uses white between photos and filling when using "Adapt to the chassis" instead of the border color of page like in iPhoto

    I used the book of images to create a book in iPhoto several times because the line between the pictures and the filling when I use 'Adapt to the chassis', is the same color as the color chosen for the borders of homepage and text boxes.  It is seamless.

    I just tried to use the book of images in pictures but the line between the pictures and the fill to 'Adapt to the chassis' is white, and not same color I chose for the page border.  It is, therefore, very ugly.

    Is it possible to remedy this situation?

    first get a glimpse of your p = book - Preview a print project in Photos, iPhoto or Aperture to avoid problems - Apple Support - so you can see exactly what will be printed

    You cannot change how the program works so if the problem persists in the overview say Apple about the bug - http://www.apple.com/feedback/photos.html

  • Host of character is very slow and glitchy when using my own character design

    Therefore, do not misunderstand with this post - animator of the character is such a fun and effective tool in my opinion, and it works oddly when you use the preset/pre-made characters that comes with it.

    However, when I created my own character design in Illustrator from the shell that host character gives you, it seems to make the application run very slowly. I see still some movements with my character design, but a lot of times, it's whole body moves and the edges will become wobbly. I chose 'New puppet in Illustrator' and you just copy all the elements of my design in the layers that it already provided and maintained the same naming conventions. My character is not too advanced either (certainly not as detailed as the wendigo), and if I could get it works, it would save me an extreme amount of time in my animated film!

    I am running the character animation (Preview) on an iMac (OS X 10.9.5).) I enclose below my character design.

    Expert.jpg

    Hi Shane. We currently have a behavior for illustration Illustrator which is called "earthquake." If your work HAVE a lot of paths, it will move each of them and which can really slow things down. You can disable the Wiggler behavior by selecting the track of puppet, then pressing the red button next to the behavior of Wiggler.

    If it is a common problem, we will probably default this OFF. We also plan to eventually offer a similar look with Photoshop illustrations.

  • RoboHelp 6 and 7 when used on Windows 2003.

    Hello:

    I read that the latest version of RoboHelp (RH7) does not work on Windows 2003. See http://www.adobe.com/products/robohelp/productinfo/systemreqs/ for the purposes of OS of RH7. RH7 is certified for Vista, XP and 2000; but not 2003. Isn't that surprising? Anyone know what are the issues using Windows 2003 and RH7?

    Surprisingly, the online help for says-RH6 RH6 is certified on OS Windows 2000 SP4 and later Windows 2003 which means must be supported. In this case, why a later version (RH7) drop support for it?

    I ask because we are faced with several problems of performance using RH6 on Windows 2003 (we just upgraded from Windows 2000). It takes a long time to do anything in WebHelp (for RH6). Our project is huge and uses Visual SourceSafe for version control. We had no such problems with RH6 on Windows 2000.

    Thank you

    Kutra. Do you mean Windows Server 2003? If so, you may not use RH6 or any other version of a server.

  • Very slow muse and lag when using the assets of Photoshop

    Hi all

    I have a high spec machine with a SSD - my hardware is fine, but Muse is incredibly slow. Resize the width of the page to test the reactivity takes 2-5 seconds every time. It is not good either.

    I imported a lot of assets of a model on a page PSD - it is what is causing the problem? I have Photoshop generating assets, but this does not yet fix the performance lag / slow.

    Need a fix!

    Have you tried to work on a new expenses file, similar behavior?

    You can try to uninstall and reinstall Muse- Uninstall/reinstall Adobe Muse CC completely
