Recover using backup controlfile

• Database ALTER DATABASE RECOVER using backup controlfile with AUTO option

  Hello. I was recovering a database today and had a little blip.

  I have published the following:

  Database ALTER DATABASE RECOVER using backup controlfile

  I then chose the AUTO option, allowing Oracle to select all available log files so that it would recover to the last log found in the destination of archive

  However... has performed the following:

  ORA-00289: suggestion:

  Two messages above that I expected. However, I made then this:

  *

  ERROR on line 1:

  This is not what I expected. What I've done wrong? Should I once received the message "cannot open archived log", launched to CANCEL?

  I then recovered again, but used

• New added file how to recover using backup controlfile

  Hi all

  From a complete backup direct (extra number 0) I cloned a new dev server database. The next day a new data file added in Live and I took a cumulative incremental backup in Live. Live and Dev server have not even mount point. While the restoration itself I gave the name of the new set for the control of data file to remap all the data files in the new location on the dev server. Now, I want to know how to get back with cumm incr backup when a new data added live file.

  Concerning

  Jennifer

  DBA CTS team

  I restored a backup of incr 0 in dev server with the set new name command. and after that I got the database with the archives transferred to live. and then I opened the database with reset logs... now the database is open... the next day I took differential bkp live to contain the new datafile... How can you apply that backup incr 1 cumm in my dev server.

  You must restart level 0, i.e.

  1. After the level 1 backup archivelogs
  2. backup controlfile
  3. have all the backups on the dev server (level 0, 1, archivelogs and controlfile)
  4. Restore controlfile (from #2)
  5. restore the backup of level 0 (with set newname, including the new data file)
  6. recover the database
  7. Open the database with the resetlogs option.

• doubts in the database using backup controlfile recovery.

  Hi gurus,

  I have a doubt in database recovery using backup controlfile.

  I do not speak of "ORA-01207: file is newer than the control file - old control file.

  Here, any of our files archive / redo log have been lost and the problem of lack of update in the control file.

  So why open the database in resetlogs option, after recovering the database by using a backup controlfile. ?

  Thanks in advance

  Mahi

  In order to maintain the consistency of the data, the RCS should be the same in all the files of the controlfile & file REDO data current.

  By definition when you use 'backup controlfile' there a SNA expired in it.

  RESETLOG requires the RCS to 1 in order to get consistency across all files in the database.

  CREATE CONTROLFILE fills this new file with the most recent SNA that exist in the data files.

  It's just the way Oracle has been implemented.

• Recovery using backup Controlfile...

  Hi all
  
  I have a little doubt about the recovery process...
  
  Suppose I took a cold backup (after immediate stop).
  After that, I started the database, made a newspaper change and delete the control file.
  
  In this case when I try to recover the database by using a backup controlfile (recover database using backup controlfile), I need to provide the name of the log file manually
  to ensure no loss of data during the recovery process.
  After that, I need start the database with the RESET LOGS.
  
  
  But my question is why the database will force you to RESETLOGS even if you haven't lost all the data or you haven't made an incomplete recovery.
  
  
  Thank you...

  A control file "backup" is a copy and is supposed to be an older file so it needs to be synchronized with the redo log using RESETLOGS files.

• ORA-01194 and ORA-00604 when using backup controlfile set #2

  Oracle 11.2.0.1 database version
  Enterprise Linux 5.4
  Database is in archivelog mode.
  
  I'm trying to recover a database according to a backup controlfile to trace #2. Create the controlfile works very well, but recover the database fails.
  
  From what I understand, the recovery fails because it cannot roll forward - 39 sequence is in the online missing redo log file. However, the database opens with the restlogs option and I understand that it should use the archivelogs in order to roll back. Since it is a new controlfile he does not know the archivelogs, but he does not accept to register or use archivelog files.
  
  The recovery as shown in set #2 doesn't seem to work as expected. Any ideas?

  I think that I am aware and do not suggest to use the hidden setting.

  What worries me is that the value #2 of the controlfile to trace the contours of the database backup can be recovered even with the lack of recovery online newspapers, but apparently this is not the case. What I also don't understand, is why he simply not restore using the information of the archivelogs. The database was not shut down properly, but isn't always the case when you lose again-online newspapers?

  Here is the text of the controlfile.sql

  You are right. But it is especially the case.perform, create the new database and will stop immediately (without demolition) and remove newspapers online OS level. And try to recover the database using backup controlfile until cancel or just recover database until cancel then enter Word Cancel and resetlogs option database open. It will work. Because it actually do not need any recovery operation. But your case you need to recover the database. You consider backup restore las and perform incomplete recovery. I think you can do the first test.

  I see you are using ASM. In this case, I strongly suggest forgetting all about giving orders for recovery of any kind in SQL * more and make sure that you have completely mastered RMAN. RMAN is the only reliable tool that can be used to do anything in ASM. In general, it is a very bad idea to mix managed by users and managed by RMAN recovery mechanisms: you ask just for confusion all round!

  Also, I see someone suggesting 'Restoration until the 122114 seq archivelog', but it is false. If you run the syntax in this way, eventually you recovery until the end of the log 122113 and not enforce a 122114 again, that seems to exist. Numbers you put in an rman command "set until" are not exhaustive, so if you are missing journal 115, it's that you defined up to the number. You do not go around off delimbing a 1 or so just in case where, unless you plan to perform a recovery more incomplete than you can actually go out with.

  Overall, the most appropriate RMAN recovery command in this case would be, I would say:

  crosscheck archivelog all;
  crosscheck backup;
  run {
  set until logseq 122115;
  restore database;
  recover database;}
  

  More seriously: I have no idea why you are trying to recover with a bit of 'backup controlfile' in your syntax. It is only necessary if you have actually lost the original control file and have restored a backup. But since I don't see you do that ('Restore automatic backup controlfile' would be the usual thing to do with RMAN), then there is no need to specify that little bit of syntax in your orders. Now that you once asked Oracle to think he's working with a backup controlfile, however, all bets are off, so if I were you, in view of this is that a test system, I put things in a working state, and then start your recovery from scratch test. Just say 'using backup controlfile' If you actually are. If you simply mount the original controlfile that has not been lost by the disaster, so there no need to mention and the above commands should work properly.

• Why cant the controlfile be synchronized, when you use the backup controlfile

  Hi all
  
  I understand a little... .to leave a DBA of my friends...
  
  you need a resetlog to synchronize the data file headers and the controlfiles
  
  (1) you need a resetlog when you perform incomplete recovery
  (2) you can complete recovery using a backup controlfile as long as you have all the necessary archived logs and online redo logs.
  (3) but not to do resetlog after 2), you must re-create the controlfile
  
  my questions are
  
  T1) are the next point above true?
  
  (* q2) why update slope the controlfile to oracle during recovery using backup controlfile? in this case, I do not need to recreate a controlfile, isn't?

  Hi Alex and the guys,.

  Thanks for comfirming my questions.
  I wonder what...

  -resetlog was designed to synchronize the control and the data headers file isn't it?
  -When I get back, even if I am using backup controlfile, I'm actually synchronization data is not?

  Yes it's true. But also during resetlogs you get new redologs and PAPER SEQUENCE NUMBER will be 1 and the database will has new incarnation.

  so, the only reason why I need resetlog even if I finished syncing correctly to the point of failure, is simply because I am using a BACKUP controlfile?.

  Yes quite right.

• Backup controlfile to trace as 'c:\prod_ctl.txt '.

  Hi all

  11.2.0.1

  I review the output of the trace file, because I want to simulate or test this process.

  This file has two (2) sets of command. one (1) for online newspapers intact and one (1) to damage newspapers online.

  Issues related to the:

  1. What do you mean by damage, newspapers online. does that mean I lost all these redo files:

  LOGFILE

  GROUP 1 ' D:\APP\PROD\ORADATA\ORCL\REDO01. NEWSPAPER "SIZE 50 M 512 BLOCKSIZE,

  GROUP 2 ' D:\APP\PROD\ORADATA\ORCL\REDO02. NEWSPAPER "SIZE 50 M 512 BLOCKSIZE,

  GROUP 3 ' D:\APP\PROD\ORADATA\ORCL\REDO03. NEWSPAPER "SIZE 50 M BLOCKSIZE 512

  
  

  2. Why is that the two (2) are still set up orders? with the exception of the backup controlfile and open resetlogs?

  3. should I backup RMAN to perform this recovery statements?

  ===============,

  Hello

  According to the Oracle Documentation:

  RESETLOGS specify RESETLOGS if you want Oracle database to ignore the content of the files listed in the LOGFILE clause. These files do not have to exist. Each redo_log_file_spec in the LOGFILE clause must specify the SIZE parameter. The database assigns redo all online log file groups to thread 1 and enables this thread for public use by any instance. After using this clause, you must open the database by using the ALTER DATABASE statement RESETLOGS clause.

  NORESETLOGS NORESETLOGS to specify if you want the Oracle server to use all files in the LOGFILE clause as they were when the database was last open. These files must exist and must be the online redo logs rather that restore backups. The database reassigns log files groups redo the nets to which they were previously assigned and re-active threads as they authorized beforehand.

  With RESETLOGS you're going to have a new incarnation of the database and are used when you perform incomplete recovery when you do not have full recovery stack to perform a full restore.

  Do I need a backup RMAN to test this statement?

  No, 'must' use RMAN. You can perform a recovery by the managed user. Personally its always preferable to use RMAN, but if you aren't aware of the working RMAN you can go forward with the managed user.

  When I start my database is to show that the use ' MUST USE RESETLOGS or NORESETLOGS option of database open, then I used the command
  
  SQL > ALTER DATABASE OPEN RESETLOGS;
  ALTER DATABASE OPEN RESETLOGS
  *

  now, I don't have the log archiving with 819 sequence, I recover from 818. Please tell me how to do?

  Hello

  1. select * from v$log and see which log file is current. Query v$logfile to check physical file location belonging to current log group.
  2. Take bacup of your curent control file using copy/paste of your OS
  3. Issue following command in mount state
  recover database until cancel using backup controlfile
  4. When it finishes applying available archived logs, still it will ask for the location of archived logs which have not been applied, here provide path of current redo log file you got in first step. Here your recovery will finish after applying current redo log
  5.alter database open resetlogs.

• Backup Controlfile RMAN

  Hello

  If I configured the RMAN for using backup controlfile option:

  RMAN > configure controlfile autobackup on;

  I always have to do this:

  SQL ' ALTER DATABASE BACKUP CONTROLFILE TO "${CTRLBKP}" ";

  I have a script to backup RMAN (written by someone else) who issues the SQL above once the backup is complete.

  My understanding is that if the controlfile is automatically RMAN backup, there is no need to run the SQL above.

  Please notify.

  Hello

  no need to take backup using sql.

  You can also read this if you have the slightest doubt:configuration of RMAN environment

• Cannot retrieve automatic backup controlfile

  Hallo! I am a newbie to oracle studying for certification in Database Administration OCP Oracle 10 g.
  During his studies, I proposed using the instructions below for the resumption of the controlfiles
  
  SQL > ALTER DATABASE BACKUP CONTROLFILE to TRACE;
  
  RMAN > CONFIGURE CONTROLFILE AUTOBACKUP ON;
  
  To see if I could pick up the controlfiles once lost, I deleted all instances of the controlfiles, and then I ran the statement that caused the errors below
  
  RMAN > restore controlfile autobackup.
  
  From restoration to October 23, 10

  How is that possible when I had already created the AutoSave?
  
  Please help me.
  
  Thank you.

  Here is the procedure.

  # controlfile recovering using RMAN and no FRA and nocatalog

  RMAN target /.
  Set the DBID = 1188930158
  startup nomount;
  Restore automatic backup controlfile;
  change the editing of the database;
  recover the database;
  ALTER database open resetlogs;

  Have you taken the RMAN backup after you configure controlfile autobackup

  RMAN > backup database archivelog;

• How can I recover my backup disks backup after a computer crash? My HP laptop is a CMS (Windows7)

  So, recently, I had to "reset" my computer to its factory settings and I for her backup disks but when I put them in, the only options that appears is 'open folder to view files '. When I open the folder, there is another folder called "backup files", when I opened that there are files that say 0.wim, 1.wim, 2.wim, (or something similar when same) and so on. I click on and it just say "choose the program you want to use to open this file" or "Browse programs." You can also choose to watch online for a program and I did and I downloaded one that he said would work (7 - Zip). I also learned what a WIM file. I have very important documents, photos and music on my backup DVD. If anyone would know how to recover my backup on my computer, please let me know and if there are questions about the problem at hand, ask and I will do my best to respond. Thank you for your help!

  On one of the drives, probably the first one, there was also a file with the .exe extension. Restore.exe or Recover.exe. If you find it double click to run it and it will extract the aDossier on the laptop .wim files.
