How can I recover this database?

The computer that hosts my Oracle 10 g XE Server finally broke down... Luckily I have a backup of the system files, including my Oraclexe folder. I bought a new system and need to reinstall 10gXE oracle database again. I have an urgent need to convert the facility to resemble the database in the system, I lost. How can I achieve this?
Thanks in advance for your help

Best way to recover the database from my own experience is to generate and keep your DOF of the database and the table of backup data using the export utility!

And what happens when you lose your database business 6 hours after taking this export? You've lost only 6 hours of transactions.

No, the best way to recover a database must follow the procedures documented in the Guide of the backup and recovery at http://docs.oracle.com/cd/E11882_01/backup.112/e10642/toc.htm
And that starts with the use of rman to back up the database AND the archivelogs.

  • Oh, MUSE.  How can I recover this icon to my site that I built in MUSE?  I hosted it on Adobe Business Catalyst.

    If anyone knows just how to get reconnected to the MUSE for my site I've built faithfully for Adobe Business Catalyst.  What a site of the art, even if I want to change MUSE and not Business Catalyst.

    Here the guide of a Muse there in Adobe-land.

    Hi John

    Yes, you can create multiple sites in a similar way.

    But I wouldn't say you to remove the site, you should be able to connect to the admin of the site, less than some problem with Adobe ID used.

    What is the error you get when connecting to your site? have you tried to contact live chat team? If this is not the case, then please contact the support team where they will help you with your connection problem and then you can save the contents of this site.

    Thank you

    Hello

    • What were the changes made before the problem occurred?

    I recommend you perform the clean boot.
     
    Configuration of your system in a clean boot state helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

  • my old account synchronization does not work on 'forgot my password link', how can I recover my account?

    Hello
    2 minutes ago I reset my fire Fox, because I had a few Add-ons unnecessary on my fire Fox, before rebooting, I had my sync on fire fox 34 v. account after reset now I can't use my account because I forgot my password, I used this link : https://account.services.mozilla.com/forgot to retrieve my password but to pop every time this error: "unable to locate your account. Please check your user name.
    so, how can I recover my password?

    more info: I used my email inbox to find my account name and password, I found a subject of the e-mail: "Verify your account" I clicked on [Verify] and fire fox sent to this address: [email protected], > > please confirm your firefox help question!
    [click here to check your e-mail] after clicking on I visited the link, arises in fact!

    What do?

    Please help me I have so many important saved passwords and history on my latest data.

    Thank you very much.

    "before the reset, I had my account for synchronization on fire fox 34 v."

    Why do you use Firefox 15.0 now? It uses an older version of Sync - 29 Firefox and later versions use a different, more recent synchronization version that uses another type of account - https://accounts.firefox.com/signup
    The old and the new version are not compatible with each other. Users can update one account of synchronization for the new version, but there is no way to "go back"; as it appears, you can try to do it with this old version of Firefox 15.

    In addition, you absolutely need your password, without it you can not connect on Sync and if you happen to change your password - your data is erased from the sync server. The password is used for data encryption method. Without the password entered, data is useless - no way to decrypt your data when it is retrieved from the server.

    Upgrade to Firefox 35 mentioned guigs2 and try to open a session for synchronization through this version. Forget about 'update' from your account. If you were using Firefox 34 before, you already have the new account Sync. But you better have your password, because if you "reset" this account with a new password to your data will be gone.
