Synchronisation with 9i Lite

Hi,
We are planning an application that will access a couple
of corporate Oracle databases. The users will on occasion
go out on-the-road and will require a small subset of the
data on their laptop.
Is it going to be practical to use Oracle 9i 'Lite' with
snapshots to synchronise ?
The laptops have a mixture of Windows versions
(98/NT/2000/XP). Is this going to be a problem ?
Also, what triggers the sychronisation ? Is it just done
automatically as soon as the user logs into the corporate
db or does the user have some control of the process ?
Sorry for asking basic questions. We are working against
a very tight time schedule at the moment and I don't have
the luxury of being able to test the process.
Thanks,

Hi Peter,
First up, you can access data in 8.1.7 databases via 9i Lite synchronisation.
It would be practical to use 9i Lite to synchronise this data.
A mixed population of Windows 98/NT/2000/XP shouldn't be a problem - I've used 9i Lite on all of these except 98, but knowing how the client works, I don't think that'd be an issue.
Synchronisation is triggered at the client end, either by running a progream (msync.exe) provided with the 9i Lite client, or by API calls from a C++, Visual BASIC, or Java application.
The user can control the process in terms of what sort of sync is performed (send/receive, send only, receive only) and also which snapshots are synchronised - you'll need to write code to allow the user to control this but it's all in the API.
Once you have the data in the 9i Lite DB on the laptop it will be accessible via ODBC or JDBC.
Hope this helps,
Simon.

  • Bfile functionality with oracle lite for Synchronization

    Hi there,
    In my project requirement, We need to design a standalone version of the applciation which will be used by the marketing people around the globe.
    Plan is to use oracle Lite database with this application, as it synchronises with the main server on demand. During our testing we found that Oracle lite do the data transfer /synchronization perfectly but have problem with bfile type data. Precisely, the only problem we are facing is how to synchronize the file which are there on the server as bfile type. As per my info Bfile is not supported by the oracle Lite.
    Any clue will be appreciated.

    Junius,
    Greetings,
    Thanks for the reply speedy reply... I took more time in replying as we busy in evaluating the Oracle Lite version 10g.
    Well Yeah! you are right and thru packaging, we can have the files downloaded but for me its a work around. Let em explain my situation again.
    I have user specific set of files for each of its client which again gets updated quarterly. If I keep this data in the package I'll have to keep 'n' number of files in the package as about 300 odd user will be on field maintaining number of user. Another problem would be to publish and package every quarter. Thired problem would be of downloading this application as size will be too high and relevant data for each of the user would be hardly 10% of the size of the application for each user.
    I hope I have clarified the situation. Pl. let me know if you need any more info.
    Regards,

    i have already try the copy/paste thing with the ID of the file "iTunes Music Library.xml" it didn't change a thing. each time I relaunched Itunes, the ID is the first I have in the MAC.
    I have more than 5 000 files of music. I don't want to recreate one by one all my playlits.
    Many thnaks for your answers.

    You can sync iphone with one and only one computer at a time.  If you sync to another, it will erase the current content and replace with content form the new computer.  There is no way around this.
    Put everything on one computer and sync from there.
    BTW, you posted in the Home Share forum.  Your question seems to have nothing to do with home share.

  • How can I find out which .pst or .ost file itunes referres to when synchronising with outlook

    I´ve switched to iphone 4S from my 3Gs and would like to "clean" my itunes Sync before I use the new phone. Problem is, that the synchronisation with Outlook 2003 doesn´t work anymore. I guess the reason is that itunes refers to an old .ost or .pst file on my computer. I ve got several outlook profiles and changed from exchange to pop3. My question: How can I find out which .pst or .ost file itunes referres to?
    Thanks a lot in advance :-)

    Select the tune and then - Get Info - in the dialog box is a note of the Apple ID used to purchase.

  • I just updated my iPod touch to IOS 5.0.1...but after that my iPod touch cannot synchronise with Itunes. the iTunes do detect the iPod and synchronize it but for examples a new song or aplication that i just download does not appear on my iPod...

    i just updated my iPod touch 4G to IOS 5.0.1. after that my ipod cannot synchronise with itunes. during connecting to itunes my ipod seem to be synchronised with itunes but the song or application that i just downloaded did not appear in my ipod.

    - First try a rset. Nothing will be lost.
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Next try restoring from backup

    How can I save the settings of my iPhone 4 before resetting the phone in addition to saving the apps etc. by synchronisation with i-tunes

    All the phone settings are save in the backup which is automatically created when you sync the phone.

    Please clarify what you mean by "resetting" the phone. When you reset the phone, no data is deleted.  Do you actually mean Restore the phone?  See the User Guide, Appendix B for the correct terminology,

  • ICal no longer synchronising with MobileMe

    My wife has an iMac and a MacBook both synchronising with (and via) MobileMe. Both Intel machines are running Snow Leopard.
    All were synchronising perfectly, including iCal, until as requested by MobileMe, I upgraded to the New Calendar.
    Now only the Imac synchronises correctly. TheMacBook returns a pop-up stating that the iCal has "either wrong ID login OR wrong Password" !
    (Le serveur n’a pas reconnu votre nom d’utilisateur ou votre mot de passe pour le compte « [email protected] ». Assurez-vous de les avoir correctement saisis.)
    I have stopped the synchronisation and cancelled the iDisk synchronising.
    Then connected again at the level of MacBook and logged again to the account. And synchronised again. It states first login for the calander.
    The MacBook synchronises but the calendar returns the error.
    My wife's account is sub (family) account of my main MobileMe account.
    Help me please as I really don't understand nor do I know what to do !
    Regards,
    Kevin in France

    Thanks for the effort and response. I was able to contact Apple Help and I downgraded back to the old mobileme iCal. The new mobileme iCal is very inflexible. The Month header takes a huge font. Fonts on appointments can't be changed and, as a result, appointments can be seen in their entirety. There are other very irritating things about the new iCal and my conclusion is that it's just a very weak attempt at Outlook and has a long way to go before it's usable. I just hope Apple doesn't cut us off the "old" calendar which works very well (and has for some time now)

  • How to restore data (contacts mainly) after synchronising with wrong options

    Hi I hope someone can help me?
    It seems I must have changed the settings of synchronisation with PC Suite, because it suddenly deleted quite a bunch of contacts from my phone!
    Before (unfortunately long ago) I know I synchronised by combining both the PC content and the Phone content.
    Is there a detailed report to get anywhere in the depths of either phone or PC showing not only names, but also the numbers of the contacts deleted?
    I am totally frustrated and could like to eat my phone .....
    PLEASE anyone - is there any help?
    Thanks a lot for your support!
    Kind regards
    derklenepunker

    If you search on the web, there are software programmes which claim to recover deleted data from the phone memory.The extent of success of this recovery will depend on the amount of data saved on your phone after deletion, which gradually ovewrite deleted data and become permanently deleted.You can always contact SE for more information and advice. I don't know about recovering deleted data from PC suite.

  • N95 8GB synchronisation with Outlook 2007

    Cannot get N95 to synchronise with Outlook 2007 Calendar. Do I need new software download? Is it available?

    no u donot require any additional software. This can be done using PC Suite with no additional software.
    Go to PC Suite, start Synchronize. In Synchronize (Nokia PC Sync), goto Settings. In Settings, under the General tab, click on Advanced. Under "Automatic Synchronization", select either synchronize everytime I connect my mobile or Sychronize periodically and select 15min/30min/hourly. Check the checkbox "Launch Nokia PC Sync automatically on Startup"
    Click OK and voila...auto syncing of calendar and contacts with Outlook.

  • Mail constantly is synchronising with server and updating cache directory!

    Mail constantly is synchronising with server (sent messages) and updating cache directory making everything slow.
    I have a .mac account. I understand the concept of IMAP and that it information is stored on the server therefore it needs to update but surely not constantly and besides the blue bar sticks halfway through without completing. Please help.

    I have had the same issue. Rebuilding fixes it temporarily, but it comes back....Also have an issue where Mail will not download attachments automatically. They show up in grey until they are clicked...have Mail set to download all messages and their attachments, but it doesn't want to. Very frustrating. I have begun the switch to Entourage, which is unfortunate, as I like Mail more.

  • Notes from my iPad won't synchronise with my iPhone and my iCloud portal, Why?

    I use icloud on all my IOS device and on my icloud portal from every computer I work with.
    All apps I see on the iCloud portal are very useful. I have begin to work with them and they are very useful because it is suppose to synchronise with my iPhone and my iPad as well. All exept for the Notes app. The information I wrote in stopped to synchronise a few months ago, I use to have the same information everywhere  but now some information I wrote on my iPad are not synchro with my iPhone and my "iPortal".
    Is there a way to force the synchronisation between all iCloud devices and portal?
    Where is the button?

    I have solved my problem...
    Thanks anyway

  • My iMac doesn't synchronise with I Cloud. I have activated iCloud and followed all previous instructions

    I have the following problems with i Cloud:
    1.- It seems that my iMac is not synchronising with iCloud. The Dock icon for Mail shows a number of "unread" messages that is wrong.
    2.- The server at iCloud appears to be down quite often and therefore mails don't go out or in.
    3.- I have problems in sending/receving mails above certain sizes, However Gmail or Yahoo accomodate them well.

    On your Mac go to System Preferences>iCloud
    Verify the iCloud account address at the top matches that of the iCloud address on your iPhone.
    Verify on the Mac that Calendars has a check in the box.
    Now (this is probably what's wrong) In iCal on your Mac click the Calendars button (top, left) and verify the Calendar name is checked that you expect to be syncing.

  • How can I get Aperture to re- synchronise with an external folder

    Does anyone know how to get Aperture to re- synchronise with an external folder?
    I reference my images on an external hard-drive.
    I often will move images or add them via other programs. I would like to then re-sync and have Aperture add the new images to its library.
    Lightroom does this very well but no joy in Aperture.
    Joe Barrett

    OK I know understand your question
    I do this as part of my workflow - I put all images into folders on the hard drive and then import them into Aperture as Referenced Masters
    I select the Library Inspector and select the higher levelProject I want to store the images in (or create a New one)
    Then I go to the
    File
    Import
    Folders as Projects
    Then select the folder tree that you wish to import - BUT ENSURE that you select where you want to store the files.
    I keep them in the current location as I prefer to have referenced files
    also adjust the other import controls as required.
    Then run the import - it may take a while to create the library records ad Thumbnails.
    Use the Aperture Preferences window to switch off Faces.
    Hope this solves your problem

  • Help on Palm replicating with 9i Lite

    Please help!!
    I've been strugling with Oracle Lite and palm for over 3 weeks
    with little success.
    My actual status:
    - Oracle 8i as database server on Windows NT
    - Oracle 9iLite 5.0 server on a Windows 2000 machine
    - Palm OS 3.5 with Emulator
    - I'm using webtogo.exe, not any application servers.
    - I found out that there are inumerous errors that the Packaging
    wizard doesn't show, so now I only run the webtogo in debug mode
    (-d)
    - Looking at those errors, I have been able to create some
    snapshots with success.
    - When I sincronize with the palm, either by hotsync or by
    mSync, I get some nonsense errors:
    On Palm:
    - Emulator memory errors
    - Errors after mSync consolidates that don't have any reference
    anywhere else, like -9025:0
    On the webtogo console:
    - I get the error ORA-00942 (view or table doesn't exist) quite
    often
    - I get the java null pointer exception quite oftenly
    For 2 times, my replication process seemed to work. I tried some
    very simple examples (1 table with 1 column). After replication,
    the database was created and I could access the table data on
    palm through mSQL and even see my data. When that happenned I
    can replicate as many times as I want without a problem. After
    that I removed the application and tried to recreate it with the
    same parameters and it didn't work any more!!!
    I had some conclusions of which I'm not so sure anymore:
    1 - After publicating an application with the publication
    wizard, I should wait until MGP completes a cycle before trying
    to replicate
    2 - I should include all fields of my snapshot, one by one,
    instead of using *
    3 - All the tables I'll replicate must be created with the
    system user !!!
    4 - After I delete an application, I'd better create a new
    emulator session (in a palm that would mean a hard reset),
    instead of believing that the sync process will erase the old
    database properly.
    5 - The Database name on the cliente must be filled, although
    the webtogo server log doesn't say anything about it when I
    publish the application.
    My instincts tell me I should wait because there must be a patch
    on the way. My problem is that I must deliver a project that's
    complete, only lacking the replication part.
    Any ( I really mean any ) kind of help would be very welcome,
    Eduardo Thuler

    It is a Palm OS issue. v5.1 is not supported until Olite 5.0.2.2.

  • Synchronisation with iPod

    hello
    just a little question...
    I've got an iPod 5th Generation, with color display and so on. I really like to have a comfortable and easy synchronisation with my PC, however, the problem's I can't activate the "automatically snychronisation", because if you do that iTunes will suddenly delete all your songs you have on the iPod and not on PC... Why there isn't sort of a function with I can only put the songs on iPod who aren't still on the iPod?! Nothing others, just put them autmatically on iPod...
    I lost the half of my complete library last time I tried a few things out with this ******' "synchronisation-function"! As it works now, I can't need it at all
    I just like to use my 30GB iPod as a second Harddisk, especially for saving music of course...
    Is there something I haven't seen? Otherwise I really have to invest so much time in this **** synchronisation?!?
    How do you do that?
