• incomplete recovery of a data file.

  I'm performing incomplete recovery of a data file that uses the following scenario.
  SQL > select * v log$;
  shows current journal seq is 10;
  
  I perform dml as follows:
  SQL > update hr.emp set salary = 1000;
  SQL > commit;
  
  Now, I've deleted log archiving with sequence # 9 alongwith users.dbf datafile.
  Now to perform an incomplete recovery of the datafile, users.dbf. I followed the following steps.
  RMAN > the judgment;
  RMAN > bootable media.
  RMAN > run
  {
  until the sequence 9;
  restore data file 4;
  recover datafile 4;
  }
  RMAN > alter database open;
  Now, when I ask about hr. EMP, it shows the updated lines, i.e., salary column has been updated with 1000;
  I want to know that after the incomplete rcovrry until the seq, what other newspapers is applied. My example shows that this newspaper seq 10 has also been applied. Pls help me to improve my understanding.
  I can't understand the reason to get updated when the incomplete recovery lines.

  Hello.

  You cannot perform incomplete recovery of a single data file. After recovery, before opening the database, all SNA must be synchronized between controlfiles, redo logs and data files. A single data file must be restored and recovered to the last SCN for the database to open. If you want / need to do incomplete recovery, always restore ALL data files, recover their until the desired point in time and then open the database with resetlogs synchronize all data with controlfiles and redo logs files.

  In your case, you have made a complete recovery of the data file. Very probably data repeat still available in the online redo logs were used to recover the data at the last CSS file (since you said that you have removed the archiving log - which, incidentally, makes your online backup no need for a full recovery, after the redo logs switch line and crushes with sequence #9 redo log and beyond).

  When experimented with incomplete recovery, until the RCS or at least up to the time, it allows you to specify the point in time recovery with much more accurately and without guessing, what happened in whatever sequence of journal. You must manually remove the files of data or archivelog files before playing with incomplete/complete recovery. In fact, it is a good practice not to delete the database of linked files: o)

• incomplete recovery until error

  I want to perform incomplete recovery with RMAN using up to that time, I performed the following tasks
  
  stop immediately;
  bootable media;
  ALTER session set nls_date_format ='YYYY-MM - DD:HH24:MI:SS';
  
  RMAN target sys/sys@alvis
  
  Run {}
  until the time ='2011 - 02 - 10:15:25:00';
  restore the database;
  recover the database;
  ALTER database open resetlogs;
  }
  
  
  but it shows the following error
  
  RMAN-03002: failure of the command set to 10/02/2011 16:41:31
  ORA-01861: literal does not match the format string
  
  
  Wat could be the problem?
  
  
  Thanks in advance

  You set your NLS_DATE_FORMAT in a database session, however, your RMAN connection is for another session.

  Try setting NLS_DATE_FORMAT as an environment variable in your OS BEFORE connecting to RMAN command-line.

  Something like:

  C:\>SET NLS_DATE_FORMAT=YYYY-MM-DD:HH24:MI:SS
  C:\>RMAN sys/sys@alvis
  

  or

  $ NLS_DATE_FORMAT=YYYY-MM-DD:HH24:MI:SS
  $ export NLS_DATE_FORMAT
  $ RMAN sys/sys@alvis
  

• ORA-01830 during an attempt of incomplete recovery

  Hi guys,.
  
  I practice the incomplete recovery but my RMAN script fails with the following error:
  ORA-01830: date format picture ends before converting all of the input string
  
  Here's the RMAN script
  
  RUN
  {
  May 7, 2010 until 05:00 ";
  restore the database;
  recover the database;
  ALTER database open resetlogs;
  }
  
  My NLS_DATE_FORMAT has the value
  * # env | grep-i nls *.
  * # NLS_DATE_FORMAT = HH24:MI:SS * MON-DD-YYYY
  
  Linux x 86, Oracle 10.2.0.4

  In your case, case issues (my output is in windows, but should be the same on linux)

  SQL> alter session set nls_date_format='DD-MON-YYYY HH24:MI:SS';  -- sqlplus can handle uppercase
  
  Session altered.

  4> }
  
  executing command: SET until clause
  using target database control file instead of recovery catalog
  

  Now, usually when I write RMAN scripts I'll put the nls_date_format there it will always be good for the rman session:

  run {
  set until time "to_date('07-MAY-2010 05:00:00','dd-mm-yyyy hh24:mi:ss')";
  }
  

• difference between complete and incomplete recovery

  someone can explain the difference between incomplete recovery and full

  Hello

  I think everyone had given enough information the subject.
  Always add some info might be useful: -.

  Complete the recovery: -.

  Basically completely recovered, as the word says full, why must the files (I mean that Backup should persist)
  Backups of data files, logs needed archiving, online redo logs and the controlfile are available.
  The DB can undergo or experience of damage with losing them any information. This case led to a complete recovery.

  The usual process of recovery will be (user managed)

  Make files of data performed in offline mode
  Restore data files
  Recover data files
  Make data files online

  Complete healing is possible, while the database is OPEN and until or unless that important storage spaces get made that SYSTEM or UNDO tablespaces.

  Incomplete recovery: -.

  That the specified name to lose data on purpose, it is said when a complete recovery is impossible or you want to lose some information which has been recorded by mistake or due to corruption of the files. This leads to the incomplete recovery
  Some time its effects in reason lost some files as file control and current control file does not know the current state of the DB. These cases causes too incomplete recovery.

  Incomplete recovery steps:

  Mound the DB
  Restore files
  Recover the database (up to time, cancel or change the number or number of SNA)
  Finally open the DB with newspapers to reset

  Please keep in mind that RESETLOGS Initializes the redo online files, and this is a new incarnation of the database.

  You can also use the RMAN to achieve things.

• RMAN BACKUP/RECOVERY OF DATA

  Hi friendz,.
  
  I have a legacy of or copied from earlier sources, RMAN backup scripts, which is the ff:
  
  (on the PROD server)

  No, recovery average is you have to restore before database/data file according to this time/SNA and
  need to recover this database/data file

  How do I know exact time/scn? where rman can perform recovery...

  You can use rman back catalogue or views of performance Dynamics controlfiles(v$backup_*).

  RMAN wasn't able to restore automatic backup controlfile;
  I had to restore controlfile from "c-2568036611-20100912-13.

  When you try to restore controlfile what error do you have?
  Or have you tried restore controlfile to 'your_controlfile_backup' command via rman

  run
  {
  until the time = 2010 - 09 - 12 18:30 ';
  restore the database;
  recover the database;
  ALTER database open resetlogs;
  }

  RMAN recovery ends with this error

  It seems that this error occur because of you actually restored controlfile sauvegardΘ but in controlfile are not
  any information on your logs archiving offer you have to catalogue start with "archive_log_location" through rman. After you run this command, please perform recover database and alter database open resetlogs

• Oracle - Incomplete recovery

  Dear,
  
  Database running in a - mode Archive
  
  I have a table that contains 2 million records at the time (07:00) and the inserted rows of 1 million Swiss francs to (07:02) and committed my only.
  Now, I took a backup hot all the time base (07:02).
  and by 07:05 I have deleted 1 record million and pledged my transaction.
  
  Now I need my all 3 million rear lines, then thought to perform a
  time based incomplete recovery.
  
  Here are the steps I've done...
  
  (1) I stop the database.
  (2) copied all the hot of all data files backup and restored to its original location.
  (3) has started the instance and mounted.
  3) issued the command of recovery
  > recover database until time '2010-08-27 07:02.
  
  Now I get the below error.
  
  ORA-01547: WARNING: RECOVER succeeded but OPEN RESETLOGS would get below error
  ORA-01195: online backup of file 1 needs a recovery more match
  ORA-01110: data file 1: ' D:\ORACLE\PRODUCT\10.2.0\ORADATA\FIRSTDB\SYSTEM01. DBF'
  
  What is the missing step here / what am doing wrong here?

  is not that if data that are needed to make the comparable database is in the log file during recovery and not not been archived?

  Yes. When you are prompted for the ArchiveLog, provide the name of the Redo Log file.

  Note that an incomplete recovery requires an OPEN RESETLOGS and your online redo logs will be overwritten. So, once you issue an OPEN RESETLOGS, you you not a second chance to RECOVER the database. So, I recommend that you stop the instance and take cold backups online Redo Logs.

• RMAN backup - incomplete recovery

  Hi guys,.
  
  just a test scenario.
  
  For example, I have a daily rman full backup at 20:00 yesterday. the database is in archiveloj... However we do not backup the archivelogs.
  
  This morning at 10:00, all databases, controlfile, redologs, archivelogs files are deleted from the system accidentally.
  
  
  the database can still be restore?
  
  1. create the controlfile to trace
  2. restoring the database
  3. restore database until cancel (it will be prompt will be the next newspaper which is not available)
  4. alter database open resetlogs
  
  open resetlogs will work without even a log available to apply to the rman backup archiving?
  
  Thank you

  The question is: "what is the definition of a FULL BACKUP?"

  What you have is a database backup that did not include the ArchiveLogs.
  You cannot recover the database with only a database backup unless the database backup was in State of MOUNT-no is not OPEN.

  A "backup of the closed base" is a FULL database backup.
  A "hot Database backup' is not COMPLETE unless ArchiveLogs are included.
  The command 'BACKUP of DATA PLUS ARCHIVELOG' RMAN; could meet the requirement of a full backup (although it does not include the ORACLE_HOME, EM/GridConsole tnsnames.ora, listener.ora files, etc).

• Incomplete recovery of 17 HP envy touchsmart

  I have a laptop HP Envy Touchsmart product model E1P14AV 17 t-j100 number 17.

  I'm trying to restore to the factory via a USB port, but get incomplete restoration. I tried all the methods of the HP recovery method and all three gave the same answer. It runs through everything and reload the software but gives this answer. If I click on try again it tells me to insert the recovery media.

  Try changing the date in the BIOS to 01/01/2012. Save & Exit. Boot from recovery and to run the process-, but on the first reboot, it initiates enter the BIOS to ensure the update is still. If so let recovery resume - if not change again, then restart.

• urgent server won't boot up, how rman restore/recovery?

  Hello

  Reboot server SA will not start server.

  s/n cannot access server.

  the worst case:

  If SA want to rebuild a new server, reinstall the oracle database, is there docs to show me how to restore/recovery of database using rman of rman backup files in the old server records.

  (we do not catalog rman, just the control file)

  Thank you very much!

  If SA want to rebuild a new server, reinstall the oracle database, is there docs to show me how to restore/recovery of database using rman of rman backup files in the old server records.

  Yes - there are a LOT of docs on the web. Just use your favorite search engine and the search for them. They are EASY to find.

  But the SMARTEST thing would be to find the problem with the original database and fix it.

  Another concern is that the backup of the database doesn't do 'check logical' before doing the backup. Does it mean that the recovery from backup might not work ?

  No, you need to do both.
