Piecemeal restore cold sauvegardΘ

Hello

I want to create a copy of our dev database to another server.
We have Oracle 10.2.0.4 server running on the Solaris 10 operating system.

This database has a @ 120 GB and had a lot of application data.

Now, I want to create a copy of the DB without having the application data.

If I can do the following?

1. take cold backup of this database.
2 copy the binary oracle controlfile, the log to the target server.
3. copy the data for the UNDO, TEMP, SYSTEM tablespace files and SYSAUX target.
4 restore / create the new database? -will you please give me the steps to do this?

Thank you
DR

Technically, you can do this. For steps 1 through 3, you need to do is to
CREATE CONTROLFILE without files tablespace data that you want to exclude.
OR
b. ALTER DATABASE DATAFILE DROP... at the stage of the MOUNT, later followed a DROP TABLESPACE

However, consider that your data dictionary contains definitions of all the objects in the application (Tables, indexes, procedures, views etc.) but no data. You would not be able to use objects. You may be able to extract definitions (I don't know if DBMS_METADATA fails if the object does not exist). However, you could easily do that with an export with LINES = COMPRESS N = N of the Production database.

Therefore, you could create an empty database using DBCA and then import the norows, nocompress export of Production, if you need the application object definitions in your development / test database.

  • How to restore R12 cold sauvegardΘ

    A I missed something? Please give your suggestions and the best strategy to do this task. It would be great if you can show the precise document with me.

    Kind regards
    Leopold

    Leopold,

    If you want to restore to a new server, then you definitely need to have all the OS pre - req packages. installed. If you already have an instance running on this server, the restore process will be sufficient (assuming you have the same host name, domain name, IP address, OS users,... etc).

    I suggest that you run AutoConfig, once you are done with the restore and ensure that database/application services have started successfully.

    Kind regards

  • Need help with Oracle Database Backup & Restore Cold

    Environment:

    Oracle Version: 11.2.0.4

    Platform: AIX

    A few weeks ago, I had updated my Oracle 10.2.0.1 to 11.2.0.4 database. The customer changed his mind and now I downgrade to 10.2.0.1. Unfortunately, the compatibility setting is set to 11.2.0.4. So I can't use the lower upgrade scripts.

    I had taken a cold backup of the database before the upgrade. Unfortunately, I missed save logs for recovery.

    Is there a way I can always downgrade / recovery 10.2.0.1 with cold back? or is it simply not possible without the backup of redo logs.

    Thanks in advance.

    rogers42

    I had taken a cold backup of the database before the upgrade. Unfortunately, I missed save logs for recovery.

    And what do YOU mean by "had taken a cold backup"?

    Because in addition to what John said, you also need the correct initialization file.

    Do you have a return of this init file which was taken at the same time as the backup?

    I had updated my Oracle 10.2.0.1 to 11.2.0.4 database.

    I suggest that you first reinstall the 10.2.0.1 version or Oracle before recovering your cold backup.

    You must use the EXACT name of the folder structure and file that have been used originally.

    See my response in this thread a few years ago:

    Re: Restore incompatible cold backup

    You will be able to simplify this process, some given that your backup is consistent, but the steps should help you to understand what to do.

    One of my answers in THIS thread has real details for each of the steps in the other thread

  • Is it possible to do the restore DB sauvegardΘ FS?

    Hi all

    I would like to share the question I recently confronted... Here's the scenario

    We took cold backup dB (calibration to 900 GB) of disk, via RMAN. We took FS (file system) backup of this backup disk to tape using Legato MML. There is demand to restore the DB using the same backup and be hosted on another server. We had two options:

    (1) do a restore of FS to the target (in the same directory structure) and to restore with RMAN

    (2) PCS of all backup sets to the target (in the same directory structure) and to restore with RMAN

    We chose the first, but it was a lot of time... I believe that another time demanding.

    I doubt if its possible do DB restore directly from (FS backup disk to tape backup) tape rather than do restore FS and do restore DB?

    I thank you for your answer as soon as possible, we expect several of these applications in the near future

    Concerning
    Jils

    Hi Jils,

    Temporarily your san migration will be (much) faster compared to the tape backup and restore.
    Anyway after you configure rman, the fra and the NBM (coldbackup) procedure would be:

    Make a backup of the fra:
    connection target;
    Connect the catalog rman/define_pwd@define_rcv;
    stop immediately;
    bootable media;
    backup database;
    ALTER database open;

    The fra to tape backup:
    connection target;
    Connect the catalog rman/define_pwd@define_rcv;
    run
    {
    allocate channels c1 type 'SBT_TAPE ';
    allocate channel c2 type 'SBT_TAPE ';
    backup recovery area;
    output channel c1;
    output channel c2.

    }

    On the second server

    connection target;
    Connect the catalog rman/define_pwd@define_rcv;
    # could be that you must set the dbid
    # set dbid = define_dbid;
    STARTUP NOMOUNT;
    run
    {
    allocate channels c1 type 'SBT_TAPE ';
    allocate channel c2 type 'SBT_TAPE ';
    Restore controlfile;
    SQL 'edit the editing of the database';
    restore the database;
    SQL ' alter database open resetlogs;
    output channel c1;
    output channel c2.

    }

  • Restore iOS sauvegardΘ

    I have a complete backup of encrypted to an iPhone5 via iTunes when the device was on iOS 9.3.2.

    I'll be able to install this backup on an iPhone 6 (or 7) running 9.3.3 or even 10 (when that comes out)? Thus, the backup just a backup of data and parameters or is limited by the version of the OS that my 'old' backup does not install on a device running a newer operating system?

    This is the backup of the data and settings. The iOS is not part of the backup. You can restore the backup of a unit on an older iOS to a device that has an equal or more recent iOS, but you cannot restore the backup of a unit with a latest iOS on a device with an older iOS. In other words, you can restore the backup of the iPhone 5 is with iOS 9.3.2 to a device with iOS 9.3.2 or 9.3.3 iOS or if you wait until the public version of iOS 10.

    Hope that explains it.

  • Migrate Oracle RAC 10 g 32-bit to 64-bit machine cold sauvegardΘ

    Hi people,

    For the moment I list possible migration strategies and one of the options I'm considering is to stop the Oracle 10 g 32-bit RAC on the 32-bit computer and copy data files to another machine 64-bit (oracle 10 g 64 bit RAC installed). Given that I have currently is the test installation available (will) be available later on this month, I would like to know if it is interesting to explore this method was further.

    The documentation I've found is to a single node (http://docs.oracle.com/html/B13831_01/ap_64bit.htm#CHDCDAGE) - someone has already tried this for a cluster of more?

    Thank you...

    Even if it of the CAR or not RAC, in my view, the tasks of database are same

    (1) set cluster_database = false
    (2) upgrade start
    (3) $ORACLE_HOME/rdbms/admin/utlirp.sql
    (4) start normally
    (5) run ORACLE_HOME/rdbms/admin/utlrp.sql

  • Sounds of Notification IPhone 6s on the LockScreen with IOS 9.3.5

    I have 6 s IPhone with IOS 9.3.5 and I am facing problem Sound Notifications on the lock screen. Message appears, but there is no sound. In the unlocked mode, notification sounds work as usual. I checked the following:

    1. Activating/Deactivating the mute button
    2. Maximizing the notification ringtone.
    3. Donot bother is set to normal, but it is an option that is to activate by default I guess, but I think that could cause the problem either "only when IPhone is locked.

    Please help with this problem or a bug. Thank you.

    Hi there, saadmustafa!

    Thank you for using communities Support from Apple. After reading your post, I understand that notification sounds do not play while the screen of your iPhone is locked. This happens even if do not disturb is not on the side switch is not engaged and the ring volume turned all the way to the top. I rely on my iPhone every day to stay in touch, so I know that it is important to be able to hear notifications when they are received; I'd be happy to help you!

    The "Silence: only while the iPhone is locked ' feature will only apply when do not disturb is activated. If you do not do not disturb, I can see on your screen is the case, this feature will not affect your notification sounds. There could be a number of other things that affect it, however, so I have a few troubleshooting steps you can try to help fix this problem. Give a try at each step, test your notification on the lock screen sounds once each is completed.

    1. Restart your iPhone. You can get instructions on powering the unit turned off and then back on here:
      Restart your iPad, iPhone or iPod touch
    2. Reset the settings of your iPhone under settings > general > reset > reset all settings. This will not delete your personal data (contacts, photos, calendar of events, etc.), but he'll be back customizable settings (as your ringtone and a notification alert sounds, wallpapers and view the settings of Date and time, brightness, etc.) to their default values. It will also remove saved network Wi - Fi and passwords, as well as previously used VPN or APN settings.
    3. Back up your iPhone and then restore it to the factory settings. You can find instructions for the backup on iTunes here or iCloud: How to backup your iPhone, iPad and iPod touch

      Once you have a backup, you can get the instructions to restore the iPhone here: use iTunes on your Mac or PC to restore the iPhone, iPad or iPod to factory settings

      Once the restore is complete, configure the iPhone as a new device (i.e. without putting your backup on it, at least temporarily). You can register in iCloud, iMessage, FaceTime, iTunes and App Store using your Apple ID. Then test the notification sounds.

    4. If notifications of play while the screen is locked after you set up as new iPhone, you can restore your sauvegardΘ following these instructions: restore your iPhone, iPad or iPod touch from a backup

  • What version of my file I respond Time machine?

  • Question about the recovery of the incarnation.


    Hi all

    We tried to restore and recover a database and everything by doing this, we got the error RMAN-20207: until the RECOVERY WINDOW, which was before the RESETLOGS...
