sqL. ALTER database open resetlogs;

Note: datafile header SNA will be stamped to controlfile one

If no backup of the file available trace control, then perform the Ridge below the action plan

Any other database
sqL > ALTER DATABASE BACKUP CONTROLFILE TO trace;
SQL > show dump

check in udump

now, you must modify the controlfile and do file parameter etc... You can use alerts to the same log

  • How to open encrypted, if the key has been lost in XP?

    I reinstall my Windows xp, but I can not open my encrypted data. My encrypt key has been lost

    There is no backdoor to EFS encryption.  This is why it is so important to backup your encryption certificates when using EFS.  Refer to the following article, paying special attention to the paragraph "why you should back up your certificates"

    "Best Practices for encrypting file system"
      <>http://support.Microsoft.com/kb/223316 >

    That said, if some important remains of your old system must still exist on your hard drive and have not been crushed in your new installation, there are a few programs that widening this information and try to rebuild your key.  Such a program is AEFSDR, but, frankly, it's a long shot at this point.

  • iPod touch will not got to some Web sites - "Safari cannot open the page because the network connection has been lost."

    Safari refuses to go to certain websites (facebook.com, youtube.com) on my iPod Touch and instead displays this error:

    S afari cannot open the page because the network connection has been lost.

    The bubble at the top where I typed in the URL doesn't change, it always says "facebook.com" or something else.

    No matter where I am, so it won't get fixed by resetting my home Wi - Fi router. Other sites load fine. I have reset the iPod, too, by pressing the sleep button and one on the front (whatever it's called) until I see the apple logo. I also did 'Story clear and data Web site' in the Safari settings.

    I searched the web and found a number of threads that start with similar complaints, but I can't find one where the problem has been resolved in fact.

    Thank you!

    Not "no matter where I am," means, it happens with all networks?

    If so:

    Try:

    -Reset the device iOS. Nothing will be lost

    Device iOS Reset: Hold down the On / Off button and the Home button at the same time for to

    ten seconds, until the Apple logo appears.

    -Reset all settings

    Go to settings > general > Reset and tap reset all settings.

    All your preferences and settings are reset. Information (such as your contacts and calendars) and media (such as songs and videos) are not affected.

    -Restore from backup. See:

  • The connection to the remote host has been lost.

    Seriously, almost every time I save a file and try to download it I get this error:

    The connection to the remote host has been lost. Click Refresh to reconnect.

    So I have to start again to download the file again... but no, I get this error again... until about 7 times then it will finally through. After that happening by once I have on a window of 2 minutes where I can download files without errors... then the cycle continues.

    This is driving me CRAZY! It happened for about 2 weeks. I have not recently changed all the server info. I used to download files on the same server from dreamweaver all the time with ease. My partner with the same configuration works always with ease. So why am I having so much trouble?

    I often have to troubleshoot PHP where I upload to the server to run it to see if it works, and I could have several times to download a file in the few minutes that becomes incredibly tedious task with this ongoing issue.

    Someone please help.

    Thank you!

  • How to make back to Firefox as it was a few weeks before a large number of features has been lost

    Firefox functioned very well at some point. After several upgrades he lost the feature so much that I need to go back to IE. However, I have added dozens of bookmarks, which are not in IE, so I need to switch back.

    I'm fed up with it now.

    A feature that has been lost:
    1, interactive for weather radar on websites as graphs (but not limited to) weather.com
    2. interactive graphics for graphs of trend of prices on the Google and Yahoo Finance websites
    3. cannot play videos on You Tube and other sites where they have embedded videos.
    4 were not able to right click to download videos on Real Player for a while.

    All of these features are always on IE.

    We will try to correct Real Player Downloader and Flash issues first. Read this article and see if it helps: 11.3 Flash does not load video in Firefox.

  • Wallpaper base of Windows Vista has been lost

    My Red Cardinal bird Desktop background has been lost and I want to. I don't know what happened to this wallpaper.

    Hi CU Agent,.

    If this comes to pass, try a restore of the system to a point BEFORE the problem started.  Here is the procedure: http://www.vistax64.com/tutorials/76905-system-restore-how.html.  Don't forget to check the box to show more than 5 days of restore points.  If the first attempt fails, then try an earlier point or two.  NOTE: You will need to re-install any software and updates that you have installed and uninstall any software that you have removed between now and the point of restoration, but you can use Windows Update for updates.

    I hope this helps.

    Good luck!

  • How to restore a file that has been lost and partially restored?

    I have it has not deleted, but when I started my computer a scan of indexing was performed for a deleted file.  What was restored was an older version of the deleted file.  There were parts of other files deleted also.  Or old version have been restored instead of the current version.

    I have it has not deleted, but when I started my computer a scan of indexing was performed for a deleted file.  What was restored was an older version of the deleted file.  There were parts of other files deleted also.  Or old version have been restored instead of the current version.

    It should be a little clearer, at least for me.

    What do you mean by "a scan of indexing was performed?

    What do you mean by "shares of other files deleted also?

    How the file was restored?

    Do you mean that you have run a chkdsk and it detected disk errors and attempted to remedy and that you are now looking to the files created by chkdsk (*.chk files)?

    The computer is configured to automatically perform a disk check.  He said this morning it was running a check disk and restore one of my files.  This file has been restored to a version much sooner, as well as several other files when I checked later.  I ran a check of the index that says he would restore the files, but that did not help.  It will only run chkdsk.  I think I'll have my paid gurus do.  Thanks for your help.
