Deployig to a Cluster without losing session.

Hi,
          We have a cluster setup with 4 servers. We use HttpSession and
          StatefulSessionBeans in the cluster with in-memory replication. Is it
          possible to redeploy the application to a cluster without losing
          session ?.
          Thanks,
          -Senthil.

          Not with WebLogic session replication. The session replication is "lazy"
          (only when something happens) so the best approach is to make sure there are
          no imcompatibilities and then cycle the cluster one server at a time, maybe
          one server every hour (or whatever your session timeout is).

  • How to open multiple report windows on button click without losing session?

    Hi,
    JDev : 11.1.1.2.0
    I am trying to open multiple discoverer plus report windows using my ADF application.
    My requirement is that user has to select multiple reports from the screen and by clicking on submit button all the reports should be opened in different windows.
    1) Below link provided me the the first solution but I can't go with it because my page is jsff and in jsff it doesn't support form tag.
    http://andrejusb.blogspot.com/2007/07/opening-report-window-in-adf-faces.html
    2) RichGoButton also provide targetFrame property but there is not action property in it so I can't call backing bean method with RichGoButton
    3) I have tried to open report windows using javascript window.open with ExtendedRenderKitService but on discoverer side it giving error message that Discoverer Plus cannot attach same session to multiple request.
    4) I have created one jsp page in the same folder where my jsff is kept in my ADF application and on submit button click I have launch this jsp page using afConetxt.launchDialog and in jsp scriplet I have written response.sendRedirect to report url but here all report are getting open properly to seperate windwos but my ADF application session is getting timeout so after clicking on submit button it will automatically goes to login page it cann't stay with the current page.
    Hoe you have understnad my problem and please provide me if you know any other solution aprart from above mentioned 4 solutions
    Regards,
    DevD

    sURL is query parameter value that I want to pass on jsp page. It is used to set some value on jsp page.
    If this is not a right approach then let me know how to pass the parameter in jsp page.

  • Losing session with WLS 7.02 in cluster env

              PROBLEM: We are losing our session when running in our app in a clustered environment.
              The user can use the app for a while, but then weird stuff starts happening. In
              some cases, the login check that we do at the begining of each request fails,
              because it tries to check for a login token in the session, and the session has
              been wiped out. The user gets forwarded to the login page.
              Our configuration is:
              WLS 7.0.2 (OS = Windows 2000)
              Admin Server and a managed server A at APP1 (physical machine), another managed
              server B
              at APP2 (physical machine), A and B is in one cluster. We had 6 Apache Servers
              2.0.45 (OS = Linux) and each works together with Weblogic Plugin. The weblogic
              plugin has the following configuration:
              <Location /sample>
              SetHandler weblogic-handler
              WeblogicCluster 10.1.1.11:7010,10.1.1.12:7010
              Idempotent ON
              CookieName JSESSIONID
              </Location>
              The server A and B use round-robin loadblancing, and we have a hardware loadblancer
              infront of Apache to do loadblancing for our 6 web servers.
              In weblogic.xml we config our application to use replicated for session failover.
              Losing session is randomly happened.
              Anyone of you have any idea?
              Thanks in advance.
              Harry
              

    To verify that it is WL and not your app logic, try using a different
              session replication implementation for testing, such as the one that comes
              with Coherence for Servlet 2.3 containers:

    The advice on version numbers given above is quite generic. While JDK 1.4 may work, if you want to run a supported configuration the answer to this question depends on what OS you're running. Further, BEA supports different JDK versions for running the server and for client applications. Here is the whole chart:
    http://e-docs.bea.com/platform/suppconfigs/configs70/70_over/overview.html
    Be sure to click on your operating system to get the specific information about what JDK is "fully-supported" and what is "client-only".
    Hope that helps,

  • How do I sync iPhone to new Macbook without losing data?

    Been searching the internet for several weeks now, and haven't managed to find anything that helps, so here's the deal: I've had an iPhone 4 for a bout a year or so now, and I just got a new Macbook Pro a few weeks ago. I had previously been syncing my iPhone to a shared computer, so obviously I couldn't just set up my new computer using the data of the old one. I wasn't too concerned about this, until I discovered that I couldn't sync my iPhone to the new computer without losing all of the data on it! So I'm trying to figure out how I can save my iPhone's data in such a way that I can restore it upon syncing to the new computer. To clarify, I don't need to save all of the data—I've already gotten my purchases and music transferred over, and I'm in the process of transferring my contacts and notes over, but I have no way of saving the other data. Most of it is superfluous, such as call records or web history—but I do care about game data and iMessage data. So it comes down to this: I need a way to be able to store save files for all my games AND all of the text messages in my iMessage app. I've seen lots of people recommend various file transfer programs, which I assume work for game data, but as far as I've been able to tell from the demos versions, all they'll do for iMessage is export conversations as pdf or text files. I'm not looking to save a hard copy of my text messages, I want to be able to upload them to my iPhone again as text messages (both sent and received). In other words, I'd like my phone to be pretty much exactly the same after syncing it as it is now. At least, as far as the iMessage/game apps are concerned. Maybe I didn't know how to use the file transfer programs, maybe I didn't download the right one, maybe there's another way to do it, I don't know. If anyone can help me solve this problem, I would greatly appreciate it.
    BTW, My iPhone is running iOS 7.1.2, my Macbook is running OSX 10.9.4. Also, I do still have access to the computer my iPhone is currently synced to, as well as an iPod Touch 4 that's also got most of the data I want on it, if that will help at all.

    So, just in case anyone with the same problem happens to run into this post, I managed to find a solution to this problem. There's a $35 program called iBackupbot, which works for both Windows and Macintosh. It's basically an iTunes backup service, except that it functions independently. You can also do partial restores with the program. Anyway, it's a very useful program, and it can sync data from one device synced to one computer to another device synced to another computer (or to a restored device synced to a new computer). If you're willing to shell out $35 for the program, here are the steps to restore your iPhone's data:
    Transfer all of your purchases from your old computer to your new computer, including music and videos. This program is good, but it only syncs data files, so music and apps cannot be synced over (that I can tell).
    Download and register iBackupbot on your NEW computer (http://www.icopybot.com/buy.htm)
    Plug in your iPhone
    When you iPhone appears in iBackupbot, click on its name and then click 'backup now' on the information screen. It will take at least five minutes.Once the backup is complete, you might want to test it out. I'd recommend deleting a few pictures or messages, and then restoring from a backup, to ensure that the backup worked properly.
    Quit iBackupbot. (It's a good program, but I've noticed that it's kind of glitchy, and it works best on the first action of each session)
    Wipe your iPhone and set it up as a new one. Make sure you link it to the same Apple ID that your new computer is associated with.
    Once your iPhone has been set up, sync it to your new computer and re-download all of your music, apps, and other purchases.
    Change your iPhone's name (this is to check and make sure that iBackupbot recognizes your iPhone)
    Reopen iBackupbot, and click on your iPhone's name when it appears.
    Right-click the name and select 'restore from backup.'
    Leave the settings alone, and check 'full restore'
    This will take quite a while, and your iPhone will probably be glitchy when the restore is finished. Quit iBackupbot again, and then power your iPhone off and then back on.
    Check all of your apps (including the system apps) to make sure that all of your desired data has been put back on your iPhone.For me, out of about 70 downloaded apps, 4 did not have any data when I had finished the restore. If this is the case, you can can try another full restore or do a partial restore this time, selecting only the apps that did not have data.
    Once you're satisfied that your iPhone has all of the data you want, sync it to you computer to make sure that it will still sync to your new computer (you never know)
    Change your iPhone's name to what you want it to be, then reopen iBackupbot.
    Do a final backup of your iPhone in iBackupbot.
    Sync your iPhone with your new computer one last time, and do a backup of it using iTunes.
    You're done!
    I hope this helps. Good luck to anyone who decides to try this method!

  • In LabVIEW6i, is there a way to make particular elements of an array invisible while the others stay visible (without losing any element's info.)?

    I have an array of clusters. Each cluster pertains to a certain oscilloscope I am controlling. There is another control which specifies which oscilloscopes I have "on".
    If a particular oscilloscope is "on" I want its cluster to be VISIBLE in the array. If a particular oscilloscope is "off" I want its cluster to be INVISIBLE in the array.
    How can I implement this in my program without losing ANY of the info. in my array?

    I suggest to use two arrays; one for user interface holding the ON clusters,
    and one for internal use holding all clusters. The diagram periodically
    updates the internal array with user interface array data.
    By INVISIBLE do you mean "skipped from the array" or displayed as an empty
    placeholder? To hide an OFF cluster you could put in the cluster a flat
    button boolean that is small and transparent when ON and large enough to
    cover the whole cluster area (and other controls) when OFF.

    My wife and I have made many purchases over several years on seperate accounts, how could we join them into one account, without losing everything? We both use Iphone 5's and share an Imac at home.

    Purchases using one Apple ID cannot be merged or transferred to another Apple ID. Purchases are forever tied to that Apple ID used. You have to decide which Apple you want to use for purchases and stick to that Apple ID so that you can share: Settings > iTunes & App Stores > Apple ID : > use the same Apple ID here to share purchases.

  • What other methods are there to re-install Win 8.1 pro without losing files & programs, if I am unable to update my Recovery image?

    So I am thinking my Windows 8.1 Pro needs a refresh, but I have not ran "recimg /createimage C:\*" for a while and because of the problems I have. I cannot create a new one, it just wont work and I've had a post on here about that issue for a while
    now and nothing has worked.  So I know I need to re-install windows but I really want to be able to keep my Programs & files.
    So my question is, are there any other methods to re-install Windows 8.1 pro without losing my programs?
    That's the reason I have not just done a reinstall, because of the time and effort needed to do this in a timely manner.  Also I need to keep my programs APPDATA intact so that my applications still work as they do now, some programs have got months
    of history and data.  Also I am not certain I still have the installers for some of my applications, I know I can get them but again its the time it would take.
    This is why I run a separate backup of my APPDATA DIR, am I right in thinking that If I did have to reinstall that I could just restore the old APPDATA data to the new Install and my programs would automatically have all there normal settings?
    So what are my options?
    Thanks peeps.

    You are talking about the menu bar of Itunes, right?
    Yes. With iTunes open the menu bar is at the top of your screen.
    where exactly is the Store/synck you iphone option?
    After you authorize the computer connect your iPhone then follow the instructions here > iOS: How to transfer or sync content to your computer
    When you are done transferring the data to the desktop, right or control click the iPhone under Devices left side of the iTunes window then click Back Up.
    That way you will have a backup just in case you need to restore your iPhone.

    Basically long story short my laptop just died, I can't get it past the start up screen and have subsequently lost all my music, files and iTunes Libary - and yes I know it's dumb of me not have a back up and I will not be making that mistake again - I have purchased a new laptop running windows 8 however as my iPhone is synced with my old laptop it will not allow me to sync with the new one without losing all of my data. Now I manually managed everything bar my apps on my old laptop but when I check to manually manage eveerything on the new laptop I obviously get the error message I will lose data when it syncs to the new laptop and I don't know what to do.
    I've lost all my music before and when I don't have my old files to back up what I lose I'm at a loss... can anyone help?
    If I click to manually manage will I just lose my apps as this was the onlyu thing synced with my old laptop? I can cope losing these....
