Backup/restore tablespaces in noarchivelog mode

In our office, there is a box of oracle 10g that is used for testing purposes.
He got only 1 database, but each user has its own tablespace.
As it is not a 'live' box, archivelog and flashrecovery have been disabled by the dba likely in favor of speed.

I have a suit of NUnit test that crosses a tablespace, and I'm trying to restore the tablespace before each race.
In noarchivelog mode, RMAN allows me to take the tablespace offline and create a backup - well.
Later, I'm capable of taking the tablespace offline again and issue a command to "RESTORE the TABLESPACE.
But then I can't bring the tablespace online without issuance of an order to 'RECOVER '.
I tried the NOREDO option but it still says that the file has a media recovery before it can be brought online.

Is there a way to bring the tablespace online without applying REDO logs?
Backup/restore of tablespace or not possible because of noarchivelog?

Thank you.

He asks for any newspaper archive, when you turn the fire 'recover' command?

When you take a tablespace offline, the tablespace is not updated with the oracle's internal clock. So when you try to bring the tablespace online, oracle estimated that the tablespace is not in harmony with the other storage spaces. That is why it requires recovery. If you turn the fire back the command simply updates the tablespace and brings online storage space after applying the data available in the online redo log.

But if the data has been flushed to redo, then it is difficult to synchronize the tablespace.

Kind regards
S.K.

  • Backup hot NOARCHIVELOG mode?

    Why is it not possible to make a backup in NOARCHIVELOG mode hot? What role archived redo log files from a backup hot?

    When you take a backup of database, you make a copy of the data file. You want to archive and back up the log as well with it! Playback is required if you restore. If you do not restore, you didn't need a replay. If you do not restore, your online redo log size is not a problem.

  • put the offline data file when the database is in NOARCHIVELOG mode

    My question is when the database is in log mode Archive No. I am not able to take the database offline.

    When I tried in my computer I noticed set-aside.

    CASES1:

    SYS > alter database datafile 5 offline;

    ERROR at line 1;

    ORA-01145: offline immediately rejected at least media recovery enabled.

    case 2:

    SYS > alter database datafile 5 immediate offline;

    ERROR at line 1;

    ORA - 00933:SQL not correctly completed order

    CASE3:

    I tried the command drop alter database datafile offline 6; (in NOARCHIVELOG mode) and it is to show the same effect that alter database datafile offline 6; (in ARCHIVELOG mode).

    * In NOARCHIVELOG mode are we really drop the data file to use the offline data file? You please tell me the effect of the dropkeyword.

    Oracle protects you. Please review ARCHIVELOG and NOARCHIVELOG mode.

    When you take the database offline in NOARCHIVELOG mode:

    (1) the file is offline

    (2) the RCS in which you took the database offline will be is more to be in the online redo logs

    (3) at this point, you need to perform a media recovery to enable again the file online (ie. restore the database)

    So you can see why you shouldn't do that.

    The DROP Offline command does not actually remove the data file. It removes the control file file details and updates the offline data file. It can be used for purposes of recovery or when you actually plan on deleting data files.

  • iPhone 6 s - 100% carbon copy backup/restore to iTunes - is that possible?

    Hello

    I am trying to find a way to save/restore an iPhone via iTunes installation so that the restoration of places any return on the phone with the same configuration (essentially, an exact clone of the original installation that is being backed up).

    Questions that I met with attempts to use iTunes for backup/restore:

    • Passwords and other security information do not restore.
    • Applications not getting restored
    • WIFI networks not get restored
    • attached randomly do not restore (some, not all).

    iCloud backups solve this problem (sort of).

    • It takes an internet connection takes too long and medium, and you are left without a phone can be used for a period of time, so that the restore process is complete. I'd rather do it via iTunes.
    • Passwords and other security information do not restore.

    Any help please? In the end, I'm looking for a way to backup my phone to a PC and restore it so it looks identical to how it did before the backup.

    For a long time (perhaps in the iPhone 4/5 days?) this process described above works, 100%. Apple changed something in recent years.

    Thank you

    Bob

    The backup does not contain music or apps, because they should be in the media library iTunes on your computer, and if you synchronize right after that the restoration of the backup is then reinstalled. Normally this is done automatically when you perform a restore if you not to interrupt.

    Passwords and health data are only saved if you choose encrypted backup.

    There is no way to make a backup "image" of the phone, but if you use Encrypted and let run until the end, that it will restore everything the way it was.

  • backup/restore problems

    So, recently, my iPhone 6 had a lot of questions (most applications would be closed from the opening, I couldn't update apps, all the texts and iMessages disappeared, Messages turns uses a lot of storage despite the removal of all, etc.) and a person on one of these forums recommended to back up the phone, restore factory settings and then restore the backup to the phone. I got no problem with that, until I tried to restore the iTunes backup. When I try to do, I get the following message: "iTunes can't restore iPhone «...»» "because the backup was corrupt or not compatible with the iPhone, which is being restored. "I read that to solve this problem, I just need to delete the backup but the problem is that it's the only backup I had to restore my phone. Is there a way to recover this backup or is my only option again?

    Thank you in advance.

    It seems that the backup could have caused all the problems you had. Backup, restore factory settings and then restore the backup are a standard troubleshooting step, but if the backup is corrupt, you can not use and you can not get corrupted.

    You can restart all and try again, but I think that the results will be the same. You need to restore as new.

  • Restore iPhone 3gs Recovery mode 1015 failed

    I have an iPhone 3G, bought when it was marketed in Australia. It was sold as unlocked network, I discovered a year or later when he suffered an iOS update, means that it was jailbroken. With the network lock in place and the prospect of my partner do not have a functional phone the next day, the jailbreak process again to operate the back on the network. The process was a success, and the phone has been kept out iOS updates more by fear to make the phone unusable again.

    But software eventually became too large for the phone and he entered retirement.

    Now we must once again, but for someone else and the architecture of phone iOS them would be nice, and they haven't needed to edge cutting.

    According to the riches of the internet, the phone can be restored from the recovery mode, which is the State I found it trying to get it back in service, plugging it into iTunes and by performing a restore. The restore process fails however.

    Occur in the following steps, as listed on iTunes.

    Restore iPhone software: iTunes progress bar ends. iPhone progress bar, about 1/3

    Check the iPhone software: iTunes progress bar ends. iPhone progress bar, about 3/5

    Restore iPhone Firmware: iTunes progress bar ends. iPhone progress bar, about 2/3

    Check iPhone Firmware: error 1015. iPhone goes back to recovery mode.

    I suspect that he has problems with the restoration of the firmware.

    So are the relevant issues;

    1. the iPhone 3 G can be recovered in a usable state?

    2. even if it is recovered, the locking system can be removed?

    Error 1015 is a result of jailbreaking the device in the past. If the connection in recovery mode and install the firmware do not work, the jailbreak done the phone useless, sorry.

    Error: 1015. You can also see the message "the requested resource is not found."

    These errors may appear if one of the situations below are fulfilled:

    • Your version of iTunes is obsolete. Download the latest version of iTunes, and then try to update or restore again.
    • Your device has a beta version of the iOS.
    • You try to install an older version of iOS (decommissioning).
    • Your device includes unauthorized changes in iOS, also known as "jailbreaking."

    Use the recovery mode to restore your device to the latest version of iOS.

    copied from help with iOS update and restore errors - Apple Support

    Only the provider that the phone had been locked can unlock the device, if it is an option, not the carrier has offered to unlocking the device back at the time of the 3G.

    I just got an iPhone 6 and when I plugged in my laptop, he asked if I wanted to restore my new phone. I said yes! But unfortunately chose the wrong backup restore with. Is there a way I can go back to how my phone was before?

    Yes, you can as long as you understand that you will lose everything that is currently on the phone.

    (1) settings > General > reset > erase content and settings

    That will make the iPhone as new.  Then, during the installation process it again once will ask you if you want to restore from an existing backup.  You can then restore the scheduled backup.

  • change the backup/restore disc

    can I change this disk will my backup/restore point to? He uses my external drive now even if I didn't change it. I have a laptop & cannot bet that the external drive connects or is connected.

    HI RJHinSA,
    You can go there. This is guidance on how to change to the high places.
    If you need more information, simply open help, support and type "how to make the backup.
    Change when you save your files

    When you configure your computer to automatically back up files, you specify a location where the files will be stored. You can change this location if you run out of space in the current location or you want to change the type of storage location (for example, a DVD, a hard disk on your computer or a shared folder on another computer on a network).

    1. Click to open the backup center and restoration.

    2. Click on change settings.

    3. Click on modify backup settings and follow the steps in the wizard. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

  • Backup/restore problem: some files not restored

    My hard drive died.  Fortunately, I had a recent backup.  I managed to restore most of my files and also finally got access to my file of Microsoft Outlook data (due to gurus on these forums).

    I'm now trying to recover the data for my financial program.  I checked the files in the backup folder, and they understand the data I want to restore.  However, when I go through the restored files, I don't find them.  I try to avoid having to enter again about 1 1/2 years of data.

    The backup was performed on a laptop Dell running Vista Ultimate and was stored on a USB external drive.  It was made using the backup/restore program that comes with Vista.

    Any suggestions?

    Thank you in advance.

    I'm now moving extra files on my USB key for added security.

    I would like to know if there is an easy way to remove duplicate files that take up more space on my hard drive.
