9.2.0.6 moving database files and redologs using the dd command.

Hi all,

I need to know if someone have take a cold copy of database (data file and redologs) using the unix dd command.
The problem is related to the value to be assigned to "bs" in the DD.

For the data file, I know to do the same thing of block_size for the tablespace. I'm not sure of the value to assign to "bs" to the redologs.

Any suggestions are appreciated.
Thanks in advance

Adriano

PS. I'm pass raw partitions of the data files and of redologs from HP - UX 11.11 RISC on SYMM8830 for HP-IA64 using lvm on HP XP24000 with veritas.

as to the "bs" to command "dd"?

DD if = of = bs = 1000M

If your raw device is in GBs, you can give a higher as 1024M... Sometimes the operating system does not have higher values as 1 GB... in this case, you can give all the values as 1024 K, 100 M, 500 M... Like this...

    You can contact your computer manufacturer and ask them to send you a set of recovery disks.

    They should do this for a small fee.

    To reinstall Vista using their recovery disk/s, you start from the 1st recovery disk they provide and follow the manufacturer's instructions to reinstall:

    The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

    Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

    Some manufacturers have more available Vista recovery disks.

    If this happens, you may need to try this instead:

    Other manufacturers recovery DVDs are should not be used for this purpose.

  • Unable to find files and folders using Windows Search

    Original title: Windows search returns no results, but only for a single user - another user works very well - Windows 7

    All of a sudden windows search of files and folders (from windows Explorer) do not return results - even if I'm looking for in a folder with a file name that I know is in there.  However, it works for the other user on this system.

    The things that I tried or looked at who did not work:

    • Configuration of the default folder options.
    • reconstruction of the index
    • sfc/scannow - said "windows Resource Protection found corrupt files but was unable to solve some of them.  I have the CBS. If necessary log file.
    • research done that windows has been archived 'Tour of the windows features turn on or off.
    • Ran the registry of Windows Search - he said that he fixed two things (cannot tell you what they were now), but still, it does not solve the problem. When I run it says once again that there are no errors.
    • I checked this registry key:
      HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced\\\ and key Start_SearchFiles - which was set to 2, the default
    • Under Customize Start Menu - search with public folders is selected under search for other files and libraries.

    It still does not work.  The search box in the start menu seems to work, but not for anything I get.

    Frustrated!
