How can I recover a data file if it drop without backup!

Dear friends,

I have a request.

In oracle database 10g, I created a database of test name 'medium '. I created a tablespace "support_ts" here.
In my absent mind, I deleted the data file that is associated with "support_ts" physically. Logically the tablespace information is in the database, but physically the data file is deleted.

'SUPPORT' database has no backup (export and rman), also the database is in noarchivelog mode.

Now, is it possible to recover or do I focely delete the tablespace for database information? While, in the next database startup search information tablespace "support_ts"?

Hello

Recover the data file is not possible without the backup of the data file.

You can re-create the control file and the startup of the database.

Steps to recrete the control file.

1. change controlfile backup of database to trace in the "";
2. open the control file and remove the entry from tablespace and datafile support partly noreset newspapers.
3. connect sys as sysdba
4 cancel immediately / closed stop
5 startup nomount
6. paste balls noreset controlfile content
7. After you have created the mount controlfile and open the database.

Kind regards
Prasanna

    Help!  How can I recover all my files that I lost?  I was answering an e-mail message when I heard a couple of clicks then my computer off.

    I thought that my computer was destroyed.  Nothing I tried would bring it to the top, so I decided to use the system recovery disc that

    came with my computer.  I've also downloaded all the drivers for the application.  My computer is back on, but I lost everything.

    It's like putting into service with a new computer.  I had a lot of important information in the files that I lost.  I've tried everything I know to do

    without success.  Is it still possible to recover these lost files?  Thank you very much for your help!

    Hi jamesc15546086,

    Have you deleted the PDF of the Document cloud or your system?

    If you deleted it out of the cloud of Document it will be possible to recover the file unless you have a backup for this on the system or elsewhere.

    Otherwise if you have deleted the file from your system, then you can recover it forms the trash (if its there in the Recycle bin).

  • How can I dynamically load swc files using as3? (without relying on the Flash IDE).

    How can I dynamically load swc files using as3? (without relying on the Flash IDE).

    The SWF file can be used in the same way as the CFC, which means that you don't need to "visually show" anything when it is loaded. Your code can use the classes and assets incorporated into the SWF, just as a SWC file. So if someone just to load the SWF file to see what was in it that they see nothing. They could however access programmatically to what anyone on the inside just like you, if they went to that level. But it is not as easy as just racing as SWF to see what is inside.

    I hope that all packaging several separate sovereigns will allow you to load and unload only what you need to keep the RAM usage as low as possible with a minimum load SWF.

    If you are ready, please mark all useful/correct so we can filter without response. You're welcome and good luck!

  • I have lost my EFS (ENCRYPTING File System) to change my OS. How can I recover my data.

    Some time ago I encrypt my jpeg with password file. I changed the operating system yesterday. by the operating system to format I lost my certificate EFS (ENCRYPTING File System) and at the moment I have no backup certificates. so please help me, can I recover my data. If yes how?

    Hello

    Thanks for posting the request in the Microsoft community forums!

    If your encryption key is lost or damaged and you don't have a way to recover your data, the data is lost. Also, you will lose data if you store your encryption key on a smart card and the smart card is damaged or lost. To make sure you can always access your encrypted data, you should back up your encryption certificate and key.

    You can check the links for more information.

  • How can I recover my data from the address book?

    I have an old Palm V.  My hotsync cable is bad, it synchronizes more.  And it does not load the Palm, who was fresh off for, oh, maybe a year.

    So I have always used the Palm Desktop program, to keep track of my phone numbers, etc.   Well, my cat has sprayed the pc, and I had to get a new one.  Meanwhile, with the short circuits happened, the program opens not right.  I copied what I thought, it was user files, reinstalled Palm Desktop and am open program, HOWEVER, the user box comes back as it is a brand new user and does not recognize when I paste the files in the directory!

    How can I recover my address book?  I don't like on all other data, but I NEED something like that!

    Thanks in advance.

    You have a backup file called address.dat or address.bak. If this isn't the case, then your data are most likely missing. Search your PC or the other of these two files.

  • How can I create a data file?

    I am back. I found the CFA & PEF files and I'm about to go to work and remove all these on all my drives.

    What I need to know now is how to create a single data file on a DVD for the back upward.  I have burned successfully a DVD in Encore, but I don't want to use it as a return to the top

    I think it would be deteriorating a bit. In addition, it's a file again.

    What I want is a Premiere CS4 file. This way I can always go back and make any changes or modifications in the original time line.

    If I can do this, I was planning on using a DVD - RW so I could make changes later.

    I also want to do a transfer DVD to install my project on another computer. It is a single computer video without an internet connection to mess with my OS and slow things down.

    Thanks again

    For projects, the trick will be the files of components. If they will be fit on DVD DL discs, you're OK. If they are too big (DV - AVI is ~ 13 GB per hour), then you will need a type of backup or covering the software, who will write the files on multiple disks. A better choice, IMO, would be an external to 1 to 2 to, where you can use the project manager, or just Windows Explorer and copy, to see the entire project with assets folder. I do not recommend a USB key and go at least for FW - 400. FW - 800 would be better, but you will need FW 800 connections on your computer. eSATA would be the best, but then you will need eSATA connectors.

    Good luck

  • How can I recover my old files?

    If my profile has a virus and I deleted it, but before I did I chose to save the files to a different profile. When I went to click on it, the folder was empty, but he says that the folder had files it contains. When I'm on the new profile and tried to copy that I couldn't. Does anyone know how I can get ALL my old files (photos, music, documents, Favorites, passwords, etc.)? Or at least some of them? Help, please!

    Hi samanthaswigert,


    Method 1:
    run the fixit available in the links below and check if that makes a difference-Worth to try
    Diagnose and repair Windows files and folders problems automatically

    Note: FixIt would attempt to recover bad sectors on the hard disk, in the course of this process there are chances of DATA loss from that particular area.

    Method 2: Start the computer in safe mode and then try to access the Folder. To do this, follow the steps below:

    Access Advanced Startup menu options by turning on your computer and pressing the button F8 continuously until Windows starts. In the advanced startup options select Safe Mode

    Method 3: Run an online scan to remove any threat remains on the computer.

  • How can I recover my data of user account after a Hadsruda! Bit Trojan horse destroyed a little bit it?

    So I recently discovered a hadsruda! little Trojan on my laptop. I have it removed but I was too late. The virus has corrupted somehow my user account and I can access is no longer any data associated with this account. It's mostly because my account that was destroyed was the only administrator account on my laptop (there is another standard user, but I can't access or do something about it).

    Is there a way to retrieve the data from this account? I see that it's there when I'm looking for specific files, but when I try to open the location of the file, it gives a message that the location does not exist. The data are still too much space on my hard drive so I guess that it is not completely lost. Help would be very appreciated.

    As it can be user accounts data has been corrupted, or the system files, which results in the account being unusable, you can try to repair corrupted data or system files and see if you can access the account again later.

    To perform an action of repair on possible corrupt system files, follow these steps:

    1: Make sure that the computer is connected to the internet. If you can not access the Wifi connections, plug in ethernet cable.

    2: run a commandprompt, to write and run this command: sfc/scannow

    Let it finish, then restart your computer.

    How you can run this command on command prompt (start > run > "cmd" or start > search for cmd) depends on how accessible your OS windows is still, for example you can always use the other user account?

    If not, maybe try to run the sfc/scannow command by using the safe mode (see http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7 for instructions) commandprompt from there, like safe mode can still be able to boot. If you use the SafeMode however, verify that you use the additional option to "Safe Mode with command prompt" instead of regular safe mode.

    These steps can recover your user account to the service. If those who do not resolve it, you cannot run or you're just looking for files / important data recovery, try using a recovery software tool or boot-level file Explorer. It may be in the form of a disk or CD containing the software to explore all the files from hard drive, so you can move or copy them to the user account or the Windows installation corrupted.

    I always use 1 multifunctional tool to do this called Hiren Boot CD, this software package contains a lot of explorers of disk or file. Tie just a backup drive or media to your PC, burn this CD Hiren after downloading http://www.hirensbootcd.org/download/ and then choose a (temporary) boot option or a CD at startup, and before the Windows logo comes. You will see tools contained on the boot CD, in the categories; Use either to programs back, drive hard/storage, backup, restore to find a file Explorer/mover in there and run.

  • How can I recover a lost file bookmark and content and add to my current boolmarks?

    I tried to access a folder with several subfolders with important favorite Web sites. It's not in my favorites and I searched the entire library. I need to recover this file and add it to my folders of bookmarks existing without change or disrupt the rest of the structure of Web sites or bookmarks. I guess I can get bookmarked all the value of an earlier date, but I need just to this folder. I unfortunately did not a recent backup so I don't have the ability to recover from my backup. In that case, might do the same to my backup copy of my favorites?

    If you did a lot of re-organization of your files since your last backup, then you could try the following steps to restore only the missing folder you need (providing that it existed at your last backup).

    1. Save what you have now in a new format JSON backup file;
    2. Restore the previous backup;
    3. Turn off everything except the missing records;
    4. Export to a HTML file.
    5. Restore the backup that you created in step #1; then finally
    6. Import the HTML file created in step #4.

    It is not the most elegant solution, but it will accomplish I hope that what you need, if I understand you correctly.
