NetWeaver App with JCO

Hi,
We have a custom J2EE application running on the NetWeaver 7.0 WAS that uses JCo to connect to the backend R/3 system. We have noticed that when the R/3 system goes down or is restarted the front-end JCo app is not able to reestablish the connectivity till the app or the server is restarted. Any clue why?
Thanks in advance…

Hi Sunil, something similar happened to me, I configured the JCos to use ESS, didn't have the SSO working at that time, then cause I new I was going to configure the SSO, changed the JCos to "ticket" authentication, then configured the JCos and when tried to use, was receiving authentication errors, later, I edited the JCos, set them to user/pass and back to ticket and it worked.
It comes to my mind that Webdynbpro console might have a cache or something like that, and probably there is a place to flush it or set timeout to refresh it.
I will also try to make some research.
Regards!

  • How do I use iTunes shar to share apps with in my household

    I heard that sharing apps with in a household is ok. So I wanna co it but not sure how to do it with I tunes share. Help please

    The apps that you share will be associated with your Apple ID, even if you share them with family members. So if an app needs to be updated, then you shall have to sign into your Apple ID on the computers or iOS devices which have the apps installed in order to update them.
    Probably the easiest way to share the apps is to copy them from your computer to the other computers in your family and then authorize those computers with your Apple ID. You can authorize up to five (5) computers, including your own, to use your iTunes stuff. On a Mac the apps are stored at this location; ~/Music/iTunes/iTunes Media/Mobile Applications/ (I have no idea where they are on a Windows box!) Drag & drop the apps that you wish to share from that location onto the iTunes app on the other Macs or PCs over your LAN or other direct connection. Or copy them from that location onto a USB stick and then drag & drop them onto iTunes on the other computers. After you authorize those computers for your iTunes stuff, the apps can be synced to iOS devices. You authorize the computer to use your iTunes stuff in the computer's iTunes app's Store menu.
    There are other more complicated methods of moving the apps around to share.

    how to config the hot deploy?
    thxSorry, for this delay in responding. I had set notify me with email option in Watch This topic; but I never did get any email notification.
    I use wls6.1; I think the process may be very similar to this in wls8.x. In wls6.1 (sp5), this is done via the -
    Dweblogic.ProductionModeEnabled=False or
    Dweblogic.ProductionModeEnabled=True
    in the startup cmd/sh script. Out of the box, wls6.1 is set to Dweblogic.ProductionModeEnabled=False which automatically enables hot deploys.

  • Unable to sync some apps with my ipod

    I am unable to sync some apps with my ipod touch

    See:
    Identifying iPod models
    The iPod touch (3rd generation) can be distinguished from iPod touch (2nd generation) by looking at the back of the device. In the text below the engraving, look for the model number. iPod touch (2nd generation) is model A1288, and iPod touch (3rd generation) is model A1318.

  • Remote app with Apple TV

    I use the Remote app with both an iPad and iPhone to control my first gen Apple TV. This works fine except for one thing. When I select "Apple TV" as the library, using an iPhone I have access to all my library including Podcasts. When I run the same app on my Ipad, still selecting "Apple TV" as the library, no Podcasts come up on the iPad to select - the category is completely missing.
    Has anyone else seen this issue ? Are they still there but hidden somewhere else ? Bear in mind I keep no content on the Apple TV - it is effectively just acting as a wireless device to get the signal to my TV.

    Literally nothing happens. I click the done button and hear a beep. Over and over again.
    On the phone, the passcode is still displayed.
    Thank you for your help.

  • HT203433 I downloaded apps with one appleid on my iphone.  When my account was disabled I set up a new appleid & account.  Now I cannot update apps on my iphone that were downloaded with original appleid when I login with my new apple id.  What do I need

    I downloaded apps with one appleid on my iphone.  When my account was disabled I set up a new appleid & account.  Now I cannot update apps on my iphone that were downloaded with original appleid when I login with my new apple id.  What do I need to do?

    You can write into support and ask for help reenabling the account through this link here:
    http://www.apple.com/support/itunes/contact/
    Since the applications were purchased on the older account, you will need to log into that account to update them. The newer account will not recognize the purchases because they are not a part of the purchase history for the specific account.

    It's so annoying!! I have created a new Apple ID but after I click verify it just goes back to the previous page!!!

I restarted my iPad, I logged in and out of the apple ID in the store, AND YET IT STILL WON'T WORK, PLEASE HELP!

  • When i go to sync my apps with my computer it tells me  ''are you sure you want to sync apps ? all exsisting apps and there data on (iphone) will be replaced with the apps on this itunes library'' does this mean all my data will be lost if i continue ?

    when i go to sync my apps with my computer it tells me  ''are you sure you want to sync apps ? all exsisting apps and there data on (iphone) will be replaced with the apps on this itunes library'' does this mean all my data will be lost if i continue ?

    Regarding your broken, previously authorized computer, here's how that works:
    You would authorize your new computer -- maybe you've done that already.  Then you will have two computers authorized.  Apple allows you to have up to five computers authorized at any time.  If you get to five, you can then go to your account details in iTunes and remove all authorizations.
    Bear in mind this is not saying you can synch to more tham one library.  Razmee209 and gdgmacguy's comments above are correct.  But if Apple only allowed you to authorize one computer at a time, then having a broken computer would mean you could no longer use your Apple ID with iTunes.

  • Full page prints from iPhone but not from iPad using photo app with AirPrint ?

    Full page prints from iPhone but not from iPad using photo app with AirPrint ? iPad only prints 4x6 on full size paper. It's an HP 8600.

    I also have this problem printing photos from an iPad to an Epson WF-2540 printer. It prints only 4x6 and without border (so print starts at extreme top left corner of paper). Borderless printing is not selected on printer. Printing a square photo just crops to 4x6 size.

    It's a Magic Mouse question. I have set this up in Preferences by ticking Swipe between pages with one finger and also Swipe between full-screen apps with two fingers,  however when I try to do the latter, the 2 finger swipe will take me from the app that I am on to the dashboard only and not to my other open apps.
    I also find that Smart zoom only works with some apps, for instance not with Word docs or email.
    How can I correct this please?

    Just figured out it also does not work with the Mail app.

  • Unable to close open apps with double clicking the button and when I tap screen does not respond?

    Cannot not close open apps with double clicking the button Since downloading iOS8.

    What happens when you try? Does double clicking the ?home button bring up the Task Bar of recently used apps? If so what happens when you flick up on the preview screen for the app you want to close?
    To quit an app double click the Home button to reveal the row of recently used apps. Flick up on the page preview and it will fly away and disappear. That quits the app.
