Any way to communicate a message to all cluster members?

Is there any way I can communicate a message to all cluster members?
          In my case I do some data caching within each cluster member. I'm trying to
          implement a mechanism that will enable me to have every server flush their
          cache. I was hoping that I could send the request to a servlet (on any
          machine) that in-turn would send a 'multicast' message to all app servers
          that would request a cache refresh.
          Any ideas?
          Thanks.
          Marko.
          

JMS topics are great for multi-server synchronization.

  • I just bought an new ipad mini with wifi and cellular. Is there any way to send text messages to people and contacts that do not have iphones such as friends with blackberrys or a samsung galaxy smartphone.

    I just bought an new ipad mini with wifi and cellular. Is there any way to send text messages to people and contacts that do not have iphones such as friends with blackberrys or a samsung galaxy smartphone from this ipad. Everytime I try to send a message to a person that does not have an Apple product ( Iphone or Ipad ) it comes up saying contact is not registered for iMessage and wont send it. I can only send them a message from my iPhone 4 instead. Do I have to install a new App from the App store to send these non iMessage cell users a message?

  • Any way to display a message when Flash is not found on the iPad?

    Apple is obviously rejecting Flash to protect it's 'App' revenue.  I've  been on Android phones that run Flash and display all my content  perfectly smooth.  It can be quite frustrating how they are trying to  bury it when I still have yet to see HTML5 replicate the type of  interactive content Flash is capable of producing. 
    Is there any way to display a message on the iPad when the Flash player is not found?
    I'd like it to says something along the lines of:
    "Unfortunately the Apple iPad does not support the Flash player  because their business interests do not want it taking away from their  App revenue.
    Did you know that the Dell Streak, HTC Flyer, Blackberry Playbook,  Motorola Xoom, Samsung Galaxy Tab, Toshiba Thrive, and HP Touchpad all  support the Flash player?"
    My HTML code looks something like this...
    <html>
    <head>
    <title>My Page</title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    </head>
    <body bgcolor="#ECECEC" leftmargin="0" topmargin="0" marginwidth="0" marginheight="0">
    <body onresize="setFlashSize()">
    <div id="flashid" style="width:100%; height:100%;">
    <script type="text/javascript" language="JavaScript">
    function setFlashSize(){
    var viewportheight = document.body.clientHeight;
    var viewportwidth = document.body.clientWidth;
    var mydiv = document.getElementById("flashid");
    var styleheight = parseInt(mydiv.style.height);
    var stylewidth = parseInt(mydiv.style.width);
    if (viewportwidth<880){
    document.getElementById("flashid").style.width = 880+"px"; }
    else {
    document.getElementById("flashid").style.width = 100+"%";}
    if (viewportheight<760){
    document.getElementById("flashid").style.height = 760+"px"; }
    else {
    document.getElementById("flashid").style.height = 100+"%";}
    setFlashSize();
    document.write('<object data="index1.swf" width="100%" height="100%" type="application/x-shockwave-flash">');
    document.write('<param name="movie" value="index1.swf" />');                      
    document.write('<param name="allowScriptAccess" value="always" />');       
    document.write('</object>');
    </script>
    <noscript>Javascript must be enabled to view Flash movie</noscript>
    </div>
    </body>
    </html>

    Use swfobject for Flash detection and you can provide all kinds of alternate content... simple text, images, links, .js slideshow, a mov or mp4 video just for the iPhone... ANYTHING this is regular HTML. Your imagination is the only limit.
    And YES, HTML5 is a far cry from replicating Flash... so give them the best of both worlds.
    http://code.google.com/p/swfobject/
    Review this article which deals with Flash and SEO for more ideas:
    If you think that Flash is somehow bad for SEO, it's time to dispell that MYTH!
    If fact, in some circumstances I'll use Flash INSTEAD of just HTML because then I'll have better SEO than with just HTML alone.
    http://www.worldbarefootcenter.com/
    The link to World Barefoot Center in the above post is just one example. View the source code and you see a couple paragraphs of text along with regular HTML links.... but what displays is the Flash version of the image and Flash links.
    The client provided the artwork for the page... and that's what they wanted to use a .jpg image. Well yes, that could be done in HTML but it would be virtually invisible to Google. So Instead I converted the image into a Flash .swf and used swfobject to display the Flash. swfobject allows you to create alternate content inside the <div> which also holds the Flash .swf, then when the page is loaded it detects if the browser has the Flash pluggin. If it does, it displays just the Flash content, if not, it displays the alternate content. Since almost everyone has the Flash pluggin, for most people the Flash version of the <div> will display.
    The alternate content for that <div> can be any regular HTML text, images, media player, links, etc., anything that you would use if you were not using the Flash. Now the best part is that the alternate content can be "over the top" as far as optimizing for SEO, since it will not be seen by most viewers.
    Here's another example of SEO with Flash.. again, the page is just a single image provided by the client:
    http://www.ksowetsuits.com/
    View the source code. The alt content is paragraph after paragraph of information about the site, including lists and links. If it was just the HTML, it might be kind of a boring Home page. But for SEO I can go "over the top" in promoting the site, since most viewers will never see that part... but it's all indexed by search engines. The end result is BETTER SEO using Flash than just HTML.
    On another Web site, a Flash video is displayed, the alt content is the complete text narration of the video. Now how many people would take the time to read that if they could just watch the video instead?? again, better SEO with Flash than without. In fact in one case we had first page search result from that video narration within 4 hours of posting the page.
    On still another site with a Flash video, the alt content is another video, but a .mov version, which will, in effect play Flash video on the iPhone (not possible you say??). Well since the iPhone does not have Flash pluggin, it simply displays the .mov version of the video, while everyione else sees the Flash version.
    So anyway, if Flash is a part of your Web development, you should look into using swfobject and alternate content.

  • Is there any way to prioritize the Messages in ALSB?

    Hi all,
    Is there any way to prioritize the messages based on some property of the message in ALSB. For example the messages from a specific sender is to have higher priorty.

    You can configure thread pools on your different proxy/business service (dispatch policy). Therefore prioritizing client requests based on the service invoked.
    In ALSB 3.0 you will also be able to control service throughput, for example you don't want to overload your back-end system with requests from ALSB.

  • Is there any way to delete saved messages from IPhone 4 memory?

    Is there any way to delete saved messages from IPhone 4 memory?

    Firstly you DO NOT have to do a factory reset / wipe device, it is simply not required to get the space back!!
    Mine had 3GB and I just got rid of it all, here is how:
    Make a backup in iTunes
    open iBackupBot (Google it)
    Go to the relevant backup
    Click on Multimedia File Manager and click on the other Multimedia files tab
    Sort by filename by clicking the Filename tab
    Find MediaDomain/Library/SMS/Attachments and highlight all of them, then press delete.  You can also click to export to a folder of your choice, if you want to save them that is. 
    Then go to System Files>MediaDomain>Library>SMS>Attachments
    They will be all listed here, highlight them all and press delete
    Then just restore that backup using iTunes! 
    Tadaa! Space recovered, your messages are still there but without the attachments! 
    P.S You may want to make two backups in case you get any of the above steps wrong, but it is simple to follow the above and not do anything wrong!

  • Any way to retrieve old messages to Mail after reinstalling OS?

    Hi,
    My hard drive crashed and I had to buy a new drive, so I lost the 20,000 messages that had been saved in my inbox. I use gmail and another local server (optonline). Is there any way to pull these messages off the server and into my mail program so I can have them in my new mail? I really need to be able to access these messages from my hard drive. Thanks!

    did you use gmail IMAP or gmail POP? if you used gmail IMAP then all your messages are on the server and all you need to do is set up your gmail IMAP account in Mail. it will sync with the server and you'll get all your messages. If you used gmail POP then it depends on whether you kept the messages on server after retrieving them. if you didn't they are gone. if you did then you have two options
    1. set up gmail IMAP.
    2. set up gmail POP, then go to webmail gmail->settings->forwarding & POP/IMAP and check the option to allow POP downloading ALL messages.

    Is there any way to print text messages from an iPhone 3GS?

    The only ways to print any text messages from any of the iOS devices is to either do a print screen and then print those photos, or you could look for a program called TouchCopy that will allow you to download the SMS to the computer and you can handle them from there.

    How do I get a refund?  I have tried to use this converter to change a PDF to a word document or excel document three of four times and it always fails..  I want my money back but don't see any way to communicate with Adobe.  i really just want my money back.  Very disappointed.  Also disappointed that it is so hard to find a way to communicate with Adobe that I have to resort to asking this question in this forum. 

    You need to use the CHAT link in support to reach Adobe staff. Be sure you know the product name you are trying to cancel, Adobe have lots of products, several converters etc. I think it is ExportPDF you have, most likely.
