    If you don't have a backup then the only possible solution is to go back to the store and see if they can get your old phone and create a backup of that. I know very often that Apple employees will wipe the returned iPhones clean before shipping them back to wherever they ship them.
    When you say your old phone was "broken" does this mean it is dead and won't turn on?
    Do you have a Time Machine backup of your computer, or a clone that might have this info on it?
    Other than that I hate to say you may be out of luck. Time Machine and/or a cloning program performed regularily will inevitably save your a** in situations like this.
    Good luck

  • How to recover data if one datafile was lost

    if i have a tablespace with 5 datafiles 9i or 10g...
    it's a fictional scenario :)
    one was lost during db start up
    and other 4 was still thre
    if no backup avail for restore and no archivelog for recreating the datafile
    how do i recovery data in this tablesapce ??
    thanks in advance!!
    br/ricky

    i know it's against my own statements
    just saying that i'm lazy , and don't want to write those PL/SQL to recovery the data
    alright , here is the story of why i asked this :
    Data source ------- Regional DB ------- Global DB----people
    i'm manaing regional DB which fetchs data from it's source
    and global db fetch's some key data from regional every hour
    so if one datafile in regional db was broken ,
    i don't really care about the data , most of them was already in global db ,
    and people only views report from global db
    and i can just as easy get the lost data from data source ( keeps 3 days )
    so basically what i care most is let the tables back to work ASAP ,
    and not those historical data , it does not matter that much , i only keep 2 weeks of them anyway
    it might appear strange to many DBA that protect the data as treasure....
    as a second thought , this is a somewhat silly question ;)
    thanks anyway ...

  • Rman backup with no archivelog mode

    Hi Friend,
    I did this backup many times before, to backup a test db which is not in archivelog mode.
    My procedure are the following:
    $ rman target /
    rman> run {
    shutdown immediate;
    startup mount;
    backup format '/u02/RMAN/%d_LVL0_%T_%u_s%s_p%p' database;
    delete obsolete;
    But strange I got now error:
    ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode
    Thanks a lot

    Hi,
    Paste the snap shot of what you actually doing and what error messages are coming. That will help to analyze the problem.
    This basically happens when your shutdown is not normal or clean.
    One way is to again startup the database and then issue shutdown Normal.

  • System datafile block corruption - no backups and database in NOARCHIVELOG mode

    Dear All,
    Database version - oracle 11.1 Enterprise
    OS - RHELinux 5.8
    What are the options of recovering from physical block corruption when there are no backup available to perform block media recovery?
    V$DATABASE_BLOCK_CORRUPTION reports two segments corrupted (please see attached image for details).
    1 table in system datafile - sys_fba_barrierscn
    1 index - (applicaiton index)
    What are my options?
    I know there is a possibility that the database will not restart after a shutdown due to corruption in system tablespace.
    Database is in noarchivelog mode. So online backups are not possible and there aren't any full backups either.
    I am thinking of below,
    1. Run dbms_repair with fix_block_corruption. - Still database startup might fail?
    2. Shutdown the database and take offline full backup with RMAN MAXCorrupt option.
    Appreciate your suggestions and advises.
    Thanks
    Stefan

    Thanks Sybrand,
    Agree with your first two suggestions .
    Also scheduled a expdp job tonight. (Only backup like thing they had was a expdp cron, but until today all the large tables were failing due to small undo_retention).
    Yes. Flashback is not used. So hopefully it will not affect the a database restart i guess?
    Related to dbms_repair, I was referring to - http://askdba.org/weblog/2010/08/physical-corruption-ora-1578-part-3/.
    Where DBMS_REPAIR.FIX_CORRUPT_BLOCKS and DBMS_REPAIR.SKIP_CORRUPT_BLOCKS used.
    Which i think will not use any redo.
    Thanks

  • My TEMPORARY TABLESPACE DATAFILE was lost

    I completely lost temporary tablespace datafile,

    (there is no backup)

    It is just a temporary tablespace, who cares. Just drop the tablespace and re-create it.

  • My iPhone 5 was restored from backup, and while it was restoring everything else all my pictures slowly went from 900 to none. where did they go and how do I get them back?

    My iPhone has been acting very strange lately and the only way to get it to turn on and function is to restore it. I restored it from a backup of my phone before I restored it. I was mostly worried about my pictures. I was relieved to see them all there,
    until the number of photos in my camera roll and other albums began to go down. soon enough, all the pictures I had restored were deleted. where did they go and how can I get them back?

    Hi bluegrandpanash,
    Thanks for visiting Apple Support Communities.
    If you backed up your iPhone to iCloud before updating the software, first try the steps under "Restore from an iCloud backup" in this article to recover your data:
    iOS: Back up and restore your iOS device with iCloud or iTunes

  • Ios 5 upgrade lost my backup and i no longer have any purchased apps help?

    did the upgrade to the new ios 5 and found it that it could not find my backup that it had made just before the installation...and now that the upgrade is done i have no idea where all my purchased apps went?

    Apps are not included in the backup, nor is any itunes content.
    You should always make sure that everything is on your computer before updating.
    If you have failed to do this, then you will have to redownload.  Open itunes store, click Purchased under Quick Links

  • My ipad was running a backup and it was interrupted and now I can't get it to sync

    I can't even do a restore.  All I get is that there was an error when backing up

    Try a force-restore:
    1. Launch iTunes but do not connect the iPad.
    2. Hold down the iPad's Home and Sleep buttons at the same time. This will force the screen to fade and the Apple Logo to reappear. KEEP holding the two buttons down until the screen goes black.
    3. Once the screen is black, release the Sleep button but keep holding down the Home button while you plug the cable into the iPad.  Contunue holding the Home button until the you see the iTunes logo and the picture of the cable on the screen. This may take up to 30 seconds.
    4. iTunes should now detect the iPad and you can perform a Restore.

  • During update Itunes lost all backup and phone deactivated

    Please, please help me. I'm sitting in an airport with a phone that is deactivated. I dont have another way to call for support and I've tried to do it on line and it's not working. I am really terrible with iphone/itunes/macs/computers, etc. It's really sad. I need help from a patient and kind soul and fast. Otherwise I'll be stuck at the airport forever...

        That doesn't sound like fun mawhinneylisa! Are you still having difficulties? *228 option 1 is a great recommendation if the keypad would respond. I would also try a soft reset by holding the power and home keys down. If the device still doesnt respond, restoring with iTunes would be the best option. Here's a helpful link for future reference. bit.ly/dldlU6

  • Backup and delete archivelogs on primary

    Hi,
    I have a primary db ( 11.2) and physical standby
    I understand that I should backup archive logs on primary once a while in case the logs doesn’t get shipped on time and I loss the primary db including logs that have not been shipped.. !is that’s correct?
    I want to configure rman to run couple of times a day but my concern is that I don’t want rman to remove those archivelogs ( delete input ) unless they have been shipped an applied to standby. How can I configure rman so it only deletes if logs are applied to standby?
    Thanks

    Set RMAN setting on Primary DB :
    RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
    follow this forum discussion.hope this helps.

  • Lost iPhoto, iMovie, and Microsoft Office

    I recently got my macbook pro fixed because of a system error. When I got it back all the memory was lost, including iPhoto and iMovie which I thought was weird. I tried searching for them on my spotlight but I couldn't find them. Also my microsoft office disappeared. I had Word, Exel and Powerpoint and I can't find them. I tried going on the microsoft site to insert my product key again but it won't let me download it again because I already previously had it. How do I retrieve these things?

    So what happened is they reinstall OS X and maybe changed the hard drive.
    You can get the iLife apps from the Mac App Store in your Purchases area.
    As for MS Office do you have a license key code for it? If you do you can download it from MS and apply that key code to authenticate it. If you do not have the license key code you will need to buy it again. And if you have to buy it again make sure you save the license key code for it so if you ever need to reinstall it you can reuse that key code.
