Confusion about restoring controlfile without backup

• File to restore data without backup - how it works?

  Hello
  
  I have a 10.2 database runs on Linux without a recovery catalog archivelog mode.
  I created backup current controlfile.
  Then, I created tablespace 'data' and a table with a few lines inside.
  Then I deleted all the controlfiles and the data file from the tablespace 'data '.
  I did the restore and recovery:
  RMAN > restore controlfile from autobackupp
  RMAN > restore data from the tablespace.
  creating data fno = 6 name file = /...
  restore not made; all files readonly, offline, or already restored
  
  RMAN > restore database;
  (...)
  
  It's good, but I wonder how it works: I've restored a backup controlfile and does not know this controlfile tablespace 'data '. I have no current controlfiles (they were all lost), so there is no RMAN Repository.
  Can someone explain this to me?
  
  Thanks in advance,
  Sousou

  Sousou,

  There is a complete recovery (which means your controlfile is up-to-date, and you get so far) and incomplete recovery.

  If you do not issue
  until the logseq | Yvert | date
  Before you restore and recover
  RMAN will review the latest situation.
  In this situation, there is no data of tablespace, RMAN is unnecessary restore this tablespace.
  Restore the controlfile doesn't help here, such as structural changes in the database result in an automatic backup of the controlfile.
  You restore the most recent backup, so in this automatic backup tablespace has also disappeared.

• confusion about rman restore

  Hello world
  I have some confusion about rman restore and recover procedures. I read doc available in this regard and google as well. A few more questions unanswered in my mind.
  1. do the restore backup command restore controlfile also alongwith datafiles.
  2 database is running in noarchivelog mode. Suppose one of say users.dbf data files has been removed. control files intact. the same seq # is available since the last log backup. Now to restore the database, I use the following steps.
  1 rman > shutdown immediate
  2 rman > startup mount
  3 rman > restore database
  4 rman > restore database
  5 rman > alter database open;
  
  I'm wrong. This is the one. In this scenario, the steps above can be used.
  
  3. even when logseq is not available when the database is saved, I take the following steps.
  1 rman > startup nomount;
  2 rman > restore controlfile autobackup.
  3 rman > change the editing of the database;
  4 rman > restore database;
  5 rman > recover noredo db;
  6 rman > alter database open resetlogs;
  It is a right. can I adopt this procedure in my scenario.
  
  Please do not give all the links I want some explanation of your minds.

  If after the last COLD backup is there not get command of newspaper (this means journal seq number is the same), so you can restore your database since the last backup and can retrieve it. And if thi does not need perform full restoration/recovery. At instead step 3 with DATA RESTORE (or RESTORE TABLESPACE USERS) file and step 4 instead with RECOVER DATAFILE (or RECOVER TABLESPACE USERS) and after that you can open the database by using ALTER DATABASE OPEN. If you have lost datafile users.dbf it means that this (tablespace) datafie has been automatically disconnected.

  3. even when logseq is not available when the database is saved, I take the following steps.
  1 rman > startup nomount;
  2 rman > restore controlfile autobackup.
  3.RMAN > change the editing of the database;
  4 rman > restore database;

  6 rman > alter database open resetlogs;
  It is a right. can I adopt this procedure in my scenario.

  Yes you are right in this case. There, you have to restore/recovery complete database, because of your database running in NOARCHIVELOG mode. But after database restore (step4) you can just issue RESTORE database and can open with RESETLOGS options also. Also if you have incremental backups can run NOARCHIVELOG mode even RETRIEVE the NOREDO of DATABASE then you can open the database.

• backup set is over 7 days - DB status NOMOUNT - RESTORE CONTROLFILE

  I'm doing a restore a control file with RMAN.
  
  After a STARTUP NOMOUNT from the database, I try:
  
  SET DBID = [all]
  RESTORE AUTOMATIC BACKUP CONTROLFILE;
  
  The error I get is:
  channel ORA_DISK_1: found no AUTOBACKUP in 7 days
  
  And it's true. I'm trying to restore from the backup set is more than 7 days old.
  
  I tried
  CONTROLFILE AUTOMATICALLY UP TO THE HOUR BACKUP RESTORE ' TO_DATE (17 DECEMBER 08 18:00 ',' MM/DD/YY HH24:MI:SS').
  
  and I get the same error.
  
  All the examples I've seen up to that TIME seem to assume that the status of the database is MOUNT not in NOMOUNT, which is necessary if you do not have a file of control in the first place.
  
  How to work around this problem?

  Try using restore backupset rather than Autobackup Controlfile. See if it works.

• A question about the restoration of cold backup (backup of control file is not clear)

  Hello
  
  I had another question about restoring from backup to cold. My database is in noarchivelog mode and after that take a consistent backup of cold, all I have to do is restore the backup right? -Why I got this question is because: when I save my control to trace file, I see statements like this: -.
  -Orders to recreate the table of the incarnation
  -Under journal names MUST be replaced by names of existing files
  -disc. The log files from each branch can be used for
  -re - create the folders of the incarnation.
  -LOGFILE of REGISTRY ALTER DATABASE ' / uo1/app1/arch1_1_647102958.dbf';
  -Recovery is required if any of the data files are restored backups.
  - or if the last shutdown was not normal or immediate.
  RECOVER THE DATABASE
  -Database can now be opened normally.
  ALTER DATABASE OPEN;
  -----
  My database is in noarchivelog mode now so don't know why these statements (of the registry the logfile) is there in the backup of the control file? so when I restore the cold backup of this database, it will still work OK? (there is no log file I only have the CRD files in cold don't backup - no log file archive.)
  
  Thank you
  Cedric

  It is a generic message in trace control file. It's not affect you.

• Restore from old backup in 11 g

  Hello
  
  I wonder about the process of restoring a database to an old backup rman in GR 11, 2. As I understand it, the concept is based on an incomplete recovery using a + until time + or + YVERT + clause. For example:
  
  {code}
  target of $ rman / catalog rman/rman@rcat
  
  (a) RMAN > list incarnation;
  (b) RMAN > reset in the incarnation 4 database;
  (c) RMAN > strength of startup nomount;
  (d) RMAN > run {}
  (e) RMAN > set up to that time "to_date('2010-10-05:12:00:00','YYYY-MM-DD:HH24:MI:SS')";
  (f) RMAN > restore controlfile;
  (g) RMAN > change the editing of the database;
  (h) RMAN > restore database;
  (i) RMAN > restore database;
  (j) RMAN > alter database open resetlogs;
  {code}
  
  Why do I need to reset the incarnation of the database when I restore an old controlfile?
  
  Clause of apparently OF backup AUTOMATIC is not necessary when you use the recovery catalog.
  
  How can I know that a restoration of the controlfile is necessary - I still have need to restore the controlfile if there were changes to the database structure?
  
  Thank you
  Markus

  Does this mean a RESET DATABASE is intended to be valued using the current controlfile?

  Yes

  That's why when you are using a backup controlfile a REST DATABASE is obsolete?

  Do not reset.

  What confuses me, is http://download.oracle.com/docs/cd/B12037_01/server.101/b10734/rcmrecov.htm

  Recovery point-in-time to a previous Incarnation

  In this case, you want return of database of State passed, according to time, that this time located before the resetlogs, so you need to ressetting, otherwise you will get an error.

  The following example performs a DATABASE RESET, followed of a CONTROLFILE RESTORE of backup inside a command "set tile view deleted time" running - is the RESET DATABASE needed?

  In this case, you have the recovery catalog, and if your backup controlfile location current incarnation so yes then reset the database.
  This case, you use a backup controlfile, you use a recovery catalog, because of this, you need to reset database.

• HP TouchSmart 4-1223tu Ul ENVY: restore data from backup

  Dear all,

  yesterday I was accidentally reset my laptop at the base. because I accidentally push the F11 key.

  and I just klik next and next and next. When the recovery menu came, I choose recovery for this portable partition recovery (without flashdisk or external hard drive).

  and now I get confused how to restore my data backup in the recovery partition in this laptop.

  Please help me.

  Thank you

  Irma

  @vaniarahma,

  Hello and thanks for the display on the HP support forums.  After what you've done, you'll need to order the HP support recovery media.  Regarding your data, it is gone as soon as you start the process.  You want to keep all the data should be stored on an external drive.

  Here is the link so that you reach your recovery media for your system.

  HP computers - get HP recovery disks or HP USB recovery disc

  Thanks again for posting and have a great day.

• Confusion about the requirements for the 2015 CC software

  I currently have Windows 8.0 (64 bit) which is so satisfactory and stable.  I have not upgraded to 8.1 Windows because I can't install same normal updates for Windows 8.0 without experiencing freezes system that only restore points can heal.  So for now, I would stick with what I have.  But the problem is the confusing requirements for various programs within the pile of creative cloud applications:

  Premiere Pro: Microsoft Windows 7 Service Pack 1 (64-bit) or Windows 8 (64-bit)
  Photoshop: Microsoft Windows 7 with Service Pack 1 or Windows 8.1

  Illustrator: Microsoft Windows 7 with Service Pack 1, Windows 8 or 8.1 Windows

  Dreamweaver: Microsoft Windows 7, Windows 8 or 8.1 Windows

  Hearing: Microsoft® Windows® 7 with Service Pack 1 (64-bit), Windows 8 (64-bit) or Windows 8.1 (64-bit)

  So what I'm confused about is the fact that Windows 8.0 is not listed for Photoshop, but Windows 7 and Windows 8.1 are.  Does this mean Photoshop CC 2015 is not compatible with Windows 8?  And that means that Premiere Pro is not compatible with Windows 8.1 since only 7.0 (SP1) and 8.0 are listed, I would have preferred the upgrade of software CC WITHOUT update Windows since I am picky on my installation of Windows 8 stable pipes now solid as a rock.  Fortunately, Illustrator, Dreamweaver, and hearing are compatible with all three, it seems.

  Can someone clear up the confusion, please?

  I think that my hardware is OK for this.

• Cannot restore from a backup

  I cannot restore from a backup and don't know why.

  I have a Crucial SSD of BX100 in my mid 2010 MacBook Pro. It is divided into two partitions. I got Snow Leopard on a partition and Yosemite on the other. For some reason any I've never understood the Snow Leopard guarded beachballing partition. This happened if often that I decided to wipe the disk and reinstall from my backup, do it before the beachballing began to occur.

  But I can't restore. I wiped the drive of a Snow Leopard system, repaired and reformatted. The drive is not Core Storage, this is Mac OS extended (journaled). When I try to restore the restore on it works for about two minutes and then stops. Finally, I get a message saying that the disc has been ejected incorrectly.

  I noticed that when I receive information on the drive, an element appears different from other readers and which corresponds to the element, owners enabled: no each other drive I've seen says owners enabled: Yes. Is it all just because there is no system on the partition?

  Also "ignore ownership on this Volume" must be checked or unchecked?

  Suggestions welcomed, I am baffled by this.

  Snow Leopard erase and install

  1. Insert the Snow Leopard DVD in the optical drive and restart the computer.
  2. Immediately after hearing the chime hold down the C key.
  3. Release the button when the Apple logo appears and wait for loading to complete.
  4. After the installer loads, choose your language and click on the continue button. When the menu bar appears select utility drive in the Utilities menu.  After disk utility charges select the entry out-bumpy in the list aside (mfgr. size ID and disc drive.)  In the right side of the disk utility window, click the Partition tab.  Set the number of sheets to (1) on the menu drop down. Click the Options button and select GUID, click on OK, the value of the Mac OS Extended journaled format type. Finally, click on the apply button.
  5. Once the format is complete, quit disk utility.  Continue with the installation of OS X and follow the directions.
  6. Once installation is complete, the computer will restart in the installation wizard. After completing the Setup Wizard, you will use a new installation of Snow Leopard. Open the software update and install updates recommended.
  7. If you plan to sell or to give to your remote computer, then proceed as follows: once you reformat your hard disk and reinstall Snow Leopard, the computer restarts with a welcome screen. To leave the Mac in a State OOTB (Out Of The Box), do not continue with the Setup program. Instead, press the command and Q keys to stop the computer. The installation wizard will guide you the new owner through the installation procedure, after that it turns on the computer.
  8. Download and install Mac OS X 10.6.8 v1.1 updated Combo. If necessary. It is not necessary if you are selling or giving your computer away.

• How to restore a previous backup on a new install of XP Pro and HARD disk?

  I have experienced HARD drive failure last week and has spent a lot of time trying to retrieve the data. I have a previous backup on an external drive, but when I try to restore the files to a new HARD disk with a new installation of XP Pro - files copy them all, but none of the programs or features network work?

  I was going to just to reinstall everything from scratch and just use the recovered data and log files after all the programs I use for my business back... Is there an easier way? Why Windows does not support a backup feature when it does not replicate the system on a new HARD drive correctly or I do something wrong? I can access is no longer the disc HARD death after that I got everything I could out of it (2 x backup and a copy of all important files) before it just completely fried.

  I bought a new HARD drive and installed XP then tried restoring the system to a new HARD disk and all the files are there, but not where they all should be (My Documents is empty and aka 'Of Joe Documents' are stored in a separate folder elsewhere in the new HARD drive) and none of my programs work properly - my antivirus software (CA Security Suite 2009) is , but continues to tell me that none of this is installed. Microsoft Office does not work - tells me that it's just a trial - and Outlook will not retrieve my emails, Outlook looks like not even the same. None of my networks will work with other office machines, but somehow, I have access to the internet through the network...!

  I have to format the new HARD drive in the same directory that the backup was of? (he's currently: / instead of C: / for some reason any) And the name of the account PC should be accurate? (he is currently Documents of Pete Peter's Documents instead).

  I feel blurred by microsoft because I myself prepared for something as it happens and now my company is still paralyzed because the backup does not restore the functionality of my system. Please tell me if I did something wrong and I don't have to buy all my software licenses again after reinstalling ALL my software that has already been restored from a backup. I spent the last few days to Google search without result.

• I used the backup and restore of the backup C on pc. Then tried to open saved files with IE and started acting weird.

  zip files

  I used the backup and restore of the backup C on pc.  Then tried to open the files saved with IE.  IE went into free fall.  ???

  I have no idea what opened the backup files when you have double-clicked, or if you will not quote you took after doing this...  However, the official way to 'Browse' the content of the backup...

  You can view the contents of your backup by opening the wizard to restore files.

  1. Open backup and restore by clicking on the button start , clicking Control Panel, clicking system and Maintenance and then click Backup and restore.

  2. Do one of the following:

     • To view your files, click Restore my files.

     • To display files all the, click on restore files for all users. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

  3. Do one of the following:

     • To browse the contents of the backup, click Browse for files or click Browse for folders.

       When you browse folders, you will not be able to see the files in a folder. To view individual files, use her browse for files option.

     • To search the contents of the backup, click search, type all or part of a file name, and then click search.

  If you back up to the top PC (VHD) integer then you mifght consider this trick:
  http://www.Petri.co.il/mounting-Vista-backups-using-Windows-complete-PC-Backup.htm

  According to the edition of Windows Vista that you have (and how useful, you will find the possibility to look at old versions of a given file and possibly restore), this could be useful to you:
  http://www.ShadowExplorer.com/
  (not a replacement of relief.)

  With regard to the rate of success vs. failure rate of backup - it is difficult to measure.  Indeed most of the people backs up incorrectly.  It's really * not * enough to set a backup and forget about it.  If you test ever that your backups work/glance to see if you are backing up the good thing - it's just not wise.  Although most people expect that it is essential that the backups were working properly (not a test, a real emergency) to be discovered.  Most individuals who report failures, unfortunately, fall into this category "when my aircraft crashed and I went to my backups - it turns out _ backup _ does not and never told me...» ».

  A question... If you manually create a ZIP file (not a backup) - can you still Explorer in it as a folder?

  To test... Create a folder on your desktop.  Copy some files into it - of different types.  I say COPY and not MOVE on the goal here - because you can just blow this folder and all that results from this folder later if it was all fair copies of things.

  Make a right click on this folder and choose "send to" and "compress (ZIP) file and give a name to the new 'folder '.  (It's really a file.)  On your desktop, you should have the original folder you created and copied some stuff in, and a new "folder" with the name you just gave.  If you open the 'new' folder - you should see the name of the folder that is still on the desktop and go to this folder, you should see the files.  You literally use Windows Vista to the 'discovery' inside a ZIP file as if it were a folder.

• Restore from a backup

  Hello

  I'm new to UCS and I currently see how to restore a Cluster FI from a full-State backup.

  After that I have clear the configuration on both primary and secondary, I import the configuration of my file backup successfully.

  But now, I wan´t to add the secondary FI. After start of the console configuration and answered to the question if I have wan´t at the END added to the cluster with Yes, nothing happens. She takes one our to complete the installation of the second home. It seems that there is a timer or something like that.

  Is there any command that I can use on my primary FI to reconnect to the secondary or do restore much faster?

  Thanks for your help

  Frank

  Hi Frank,.

  You do well, the process to add a second FI after the restore of a backup can take time sometimes.

  The last time I have made I've waited almost an hour without any message until finally complete the process. Unfortunately, there is no command to display a progress bar or status messages.

• Restoring an incremental backup Windows 7

  This may seem a stupid question, but it's confusing in the interface.  I want to restore my backup files of the Windows (from the control panel).  There are two dates when I did a backup of Windows.  When I go through the Restore Wizard, he mentions the 'backup period' and makes it sound as if the restoration will contain only the difference between these two dates.

  This means that if I want to restore all my files, I must first restore the previous backup and then restore it later, so that I can get those files that changed between two backups?

  Or if I just restore the most recent backup, Windows automatically give me all files that have been backed up?

  Hello

  1. have you deleted all the files between two backups?

  2. what kind of backup do you have?

  If you deleted all the files between old and recent backup, this file is not there in the recent backup. If you have a full backup of the system, all files on the computer that the precise date will be there in the backup.

  See the article and check if that helps.
