    Hi,
    usually when you upgrade, it should not delete your files, but if it happens, than you should have a backup.
    Unfortunately it is very common, that people don't know, what exactly is in the backup.
    The question is, what files exactly you are missing? Own pictures, or taken with the device? Purchased music form the iTunes Store, or own? ....
    Documents and files are mostly up to the developer of the app, if they are part of the backup, usually not and you need to transfer them before.
    In the backup you will find just pictures from the Camera Rolle folder, everything else you should have on the PC, if you had it on the device.
    Same then for music, you can transfer purchased music from the device, but your own works just one direction, from PC to device, from device to PC it doesn't work.
    In future I recomand you to be sure how the backup works or use a 3rd party app (iExplorer) where you have a little bit more "freedome" than with iTunes.
    Or you maybe just restored from the worng backup

  • How will sql certification be helpful for a datamining career

    Hi,

    Thanks in advance

    How can we know how many processors are enough to buy?
    I know that each SQL Server edition and version has it's different limitation of the number of processors it can support, for example SQL Server 2012 Standard Edition can support up to 4 sockets or 16 cores per SQL Server Instance, but this does not mean
    that I have to buy 4 physical CPUs. two could be enough. how can I know? 
    This is off topic question how can we answer it. We even dont have any knowledge about your application.
    Please speak to licensing specialist about servers and cores below link will give you more information.

  • SQL Gurus : Need Help in building SQL query

    SQL Gurus,
    Need your expertise to solve my below problem:
    - I have a column that had comma separated data, basically there are the levels in a hierarchy. eg The same column could have the following data:
    Row 1: R1L1, R1L2, R1L3
    Row 2: R2L1, R2L2
    Row 3: R3L1, R3L2, R3L3, R3L4
    For assumption purpose lets assume that there are maximum 5 Levels
    I want to put this data from this column into another table which holds the levels. I am expecting the output in another table as follows:
    Col1____Col2 ____Col3____Col4____Col5
    Row 1: R1L1___R1L2____R1L3____null_____null
    Row 2: R2L1___R2L2____null_____null_____null
    Row 3: R3L1___R3L2____R3L3____R3L4___null
    How do i achieve this ? ie coverting the comma separated values in a column to separate columns. The # of values in each columns could be different as I have showb above

  • When I open up photo booth, it just freezes and then lags. Need Help!!

    Ever since I upgraded to Lion, my photobooth freezes upon opening. It's begining to really annoying. Is there anything I can do to fix this?

    (1) First, restart your Mac and test again.  If the problem remains:
    • Use the  > Software Update... menu command to be sure
        your Apple software is up to date.  Then test PB again. 
        If your Mac still does not work correctly, continue.
    • Use Disk Utility to repair permissions and then
       download and apply the 10.7.2 Combo Update:
         http://support.apple.com/kb/DL1459
    • Repair permissions again immediately following the system restart
       that completes the Combo update.
    Properly applying the Combo version of updates sometimes
    corrects strange problems.  If not, try (2) below.
    (2) This takes longer, but it may be necessary to correct the problem.
    Start here if you need help with this step: http://support.apple.com/kb/HT4718
    • First try using Lion Recovery to repair your disk.  Then test again. 
    • If repair does not correct the trouble, your initial Lion install may have
      been faulty.  You will need to reinstall Lion to correct a faulty installation.
    When the reinstall is complete, if your  > About this Mac menu command
    does not show version 10.7.2, Mac apply the Combo update again as above.
    After you have reinstalled and updated Lion, do NOT reinstall any third party
    software, at least until you have tested PB and have it working properly.

  • HT201441 i cant find a way to contact my iphone previous owner and its locked i need help

    hi i cant find a way to contact my iphone previous owner and its locked i need help

    There is nothing anyone can do for you.
    You need the previous owners password to unlock the phone. If you can't get that, then your phone is useless.
    Nobody, not even Apple, can unlock it for you.

  • Oracle SQL Newbie need help with OE Demo Schema Installation

    Hello everybody !
    I'm hoping some kind soul can help out this SQL newbie.
    First of all i've installed 10g R2 database on a PC running XP SP2.
    Oracle is installed on the root C: drive
    I'm using the SQL Fundamentals I Exam Guide and DBA Handbook (Both Oracle Press)
    as my reference.
    My problem is this.
    I installed the DB and created the demo HR schema without too much problem
    but it's the demo OE schema i'm having problems getting running and cannot
    find anywhere on the net that outlines a step by step SQL process.
    I am using SQL Plus to execute these commands.
    My questions are these:
    -For the default tablespace i specify "users" ?
    -What do i specify for the temporary tablespace ? "temp" ?
    -what directory path do i put for the data files as parameter 6 ?
    I put down "C:\oracle\product\10.2.0\db_1\demo\schema\order_entry" but i suspect it's
    the wrong thing ?
    -What do i specify for the writable directory path for the log files ?
    Is it C:\oracle\product\10.2.0\RDBMS\log
    -And what is "Specify version as parameter 8:" line ?
    I assumed it was the db version but i believe it's wrong.
    Could somebody please help me ? I've already done my CCNA and i wanted to add oracle under my belt.
    I know if i had these few things cleared up for me it would pave the way to actually enjoying learning Oracle :)
    Thank you for any assistance :)

    I installed the DB products from the companion disk and there was no specific mention of the demo schemas. Regardless... They're all there within the demo subfolder and have already created the hr schema.. I just need somebody (I'll pay if necessary) to PLEASE just answer (what would be easy to you guys my questions so i can move on.
    this is a cap from my sql plus..

    Neethu Mohan

    Hi Neethu,
    It gives you an overwiew of blocking Oracle sessions.
    1. In general, the SQL checks Oracle sessions (SID's) that were requirering a DML lock ('TM') and now holding row locks (TX)  to prevent destructive interference of simultaneous conflicting DML or DDL operations. DML statements automatically acquire both table-level locks and row-level locks ('TX')  => holders
    It joins these with the sessions that are waiting of releasing the lock by the holders  => waiters.
    2. it retrieves the detail information wich  Oracle process , the object (table) , it's row , block  and file
    are affected by the locks.
    3. Normally, the locks are only hold for a short period of time. If you have blocking sessions it may be of a log running task (i.e. mass data update of a table) ; but it could also be a application bug due to improper handling of concurrent updates of the same object.
    4. Tuning
    V$tables are expensive to query: Why?
    v$ tables are generally Oracle memory structures.
    v$ tables are not read consistent.
    v$ tables require latches to access -- cannot modify and read memory at the same
    time.
    heavy access to v$ tables like this may cause some serious heavy duty contention.
    Especially if you self join V$lock several times.
    So the best would be to save the contents of V$LOCK in some table:
    Create table mylocks as select * from v$lock;
    Use that table for self-joining and joins to the other tables.
    You can also CTAS the other v$ tables to bypass the performance bottleneck while retrieving
    v$ directly.
    You can empty or drop the created tables any time for new data.
    Because you want to investigate only lock hold for a longert time  to copy the v$ memory structures into
    physical tables is not a disadvantage. You certainly will wait longer on finishing your query
    instead of copy them into the tables.
    Hope this helped
