• Recovery of database of old backup and archive log file complete

  Hi expert Oracle!
  I encountered the problem where my oracle database restore.
  
  In my case:
  -My version of the database: 10.2.0.2
  -J' have a full database backup (01 - Nov)
  -J' have all the archived since (01 - Nov-> 05 - Nov) log file
  -My database down to 05 - Nov with disk error (no data file, not again...).
  -I have no backup RMAN (01 - Nov-> 05 - Nov)
  
  How to restore my database to 05 - Nov?
  
  Thank you

  After you RESTORE the DATABASE,

  Use the VALUE UNTIL to set the Point of recovery to 05 - Nov, and then RECOVER the DATABASE
  OR
  Use the SQL command "RECOVER database with the HELP of BACKUP CONTROLFILE until CANCEL" that will keep asking 'future' ArchiveLogs backup.

• Deletion of backups of level 1 and archive logs

  Hello
  
  Everyone knows that "the retention policy would be applicable on level 0 backups or only full backups.
  
  So how will be reported what backups and level 1 backup of archive logs are no longer needed for recovery?
  
  And after that as the command "remove obsolete", y at - it a command to remove these unwanted 1 level and archiving logs backups?
  
  Any suggestion?
  
  Thank you
  Nitesh.

  So how will be reported what backups and level 1 backup of archive logs are no longer needed for recovery?

  If you have the revoery retention strategy window 1 day and you take backup of level 0 Sat and then consecutive level until Friday 1 daily backup, again on backup sat level 0 will be obsolete previous level 0 backup sat and its seven consecutive level 1 so is found in the archived log alls before this level 0 current backup will be marked.

  Obsolete report will show you alls backup piece and the archivelogs that are marked as obsolete.

  And after that as the command "remove obsolete", y at - it a command to remove these unwanted 1 level and archiving logs backups?

  What do you mean by backups, undesirable level 1, on what basis you say that backup of level 1 are undesirable?

• Backups and Archives

  I have a doubt about the backups and archives.
  
  My database is in archivelog mode. Then I do a full backup of the database.
  
  RMAN > backup tag = "bk_level0_200809" effective additional 0 database;
  
  What happens with the generated archives the earliest before the backup of the database, I can remove them? or I just need to have the archives generated after the backup?

  After the first full backup, you must only archives.

  Kind regards

• Backup of archive logs

  I have a cron job that backs up complete zero on Sunday.  I have an another cron job beginning level 1 backups, Monday to Saturday.  I have a 3rd cron that runs every 2 hours for each day of the week in order to safeguard the archive logs.
  
  I have concerns with the 3rd cron job.  Lets say the data in the database has not changed in the last 2 hours.  This cron job would always run this script, create another backup rman (taking more space on the server).  Is my understanding correct that rman is not smart enough to know what data has changed during backup of the Archives of newspapers so that the two components of backup are not store duplicate information? The reason why I think it's because the size of the pieces cackup for this archive log backups stop a lot of the time very similar (but not the same) in size.

  Lets say the data in the database has not changed in the last 2 hours

  That you have taken backup the archivelog at 07:00 and the next execution of the annex is at 09:00. Say that there are about 100 archives that have been backed up at 07:00. And from 07:00 until 09:00, there was that no transactions took place, in other words, that the data in the database has not changed in the last 2 hours.

  In this case, RMAN wouldn't be backup archives that have been backed up at 07:00. If there is no generated archives between 07:00 and 09:00, RMAN wouldn't save anything.

  If the archived log was not saved, it will be.
  If the archive log was not saved and is missing, you will get an error.
  If the archived log was backed up, RMAN will not back up again.

• difference between online redolog files and archived log files

  What is the fundamental difference between archived log files and online redo log files? .. .plz keep things simple as m a newbie

  Online redo log:

  Redo online Oracle log files are filled with records of restoration by progression. A record of remake, also called entrance to roll forward, is composed of a group of agents of change, each of which is a description of a change to a single block in the database. Each instance of an Oracle database has an associated online redo log to protect data in case of failure of the instance.

  See here,
  http://download.Oracle.com/docs/CD/B10500_01/server.920/a96521/onlineredo.htm

  Archived redo log:

  Oracle Database allows you to save files to one or more destinations offline newspapers filled with repeat groups, known collectively as the archived redo log. An archived redo log file is a copy of one of the members of a group of redo log filled.

• Standy of database backup and restore help to duplicate a database

  OK, here's my situation. I save my 11.1.0.6 database from the backup server (primary backup not suitable, who ruled out a double asset) using a recovery catalog. My goal is to restore this database under another name called (TEST) on another server using the duplicate database command. My questions are:
  
  (1) I know that I can save my sleep using RMAN database, but what should I back up the control file and the spfile of the primary database as well?
  
  (2) I use a recovery catalog (who I am already registered in the primary database only with), I have to save the elements of backup of the backup above with the recovery catalog (or are they already registered since I have connected to the catalog when you take the backup of the standby database?)
  
  (3) if I need backup upward the primary controlfile, can I manually copy the file to the new server or should I create by issuing a 'backup controlfile to trace' command on the primary database server and re-create it.
  
  I guess my points of friction would be how to publish the duplicate database command, once I have all the parts. If I'm missing something please let me know. This is a database of 1.5 TB and I only have one (1) time to get this right. Lucky me... Thank you all

  (1) I know that I can save my sleep using RMAN database, but what should I back up the control file and the spfile of the primary database as well?

  * ==> spfile must be static most of the time, so that you can make a copy whenever you make changes and save it to your backup location. In regards to your controlfiles, you can back up the database your intelligence and your backups.* database

  (2) I use a recovery catalog (who I am already registered in the primary database only with), I have to save the elements of backup of the backup above with the recovery catalog (or are they already registered since I have connected to the catalog when you take the backup of the standby database?)

  * ==> Oracle documents Oracle® Data Guard Concepts and Administration 11 g Release 2 (11.2) part number E17022-05 not shows you how this.*

  (3) if I need backup upward the primary controlfile, can I manually copy the file to the new server or should I create by issuing a 'backup controlfile to trace' command on the primary database server and re-create it.

• backup and archiving of difference b/w

  I am a new user of fast food.
  Is there a difference in the protection and exploitation of archives.

  Hi akhilms:

  The short answer is that archiving is intended for storage of the previously saved data.

  Simplified data protection process is:

  Base server (with volumes arranged into protection groups)-> RapidRecovery-> backup (organized in recovery points)-> various operations of backup validation (mountability, mimicry, checksum verification, recovery points check etc.) -> Consolidation according to the retention policy planning (i.e. keep all 3 days recovery points, an hour for 2 days, then 1 a day for a week to 1 per month for 3 months then 1 per year for 5 years etc.).

  In addition, you can configure replication by using a different kernel of fast food. The cumulative process would be 'copy' the recovery points from the base of the source to the marrow of replication target. These recovery point would be consolidated as well (most of the time on a different schedule from the retention policy).

  If you feel it necessary to keep one or more strings of recovery (recovery points channels begins with a base image) altered by the cumulative process (consolidation) you can archive them. Archiving does NOT require another nucleus of RapidRecovery. Do that enough space with enough available memory (local, network, clouds) to complete the internal procedures Ops ARE / s a reasonable period of time.

• [RMAN BEGINNER] Backup and recovery

  Hi all

  Can I ask a question?

  1. they are the same ARCHIVELOG = newspapers archived DB log?

  2. can I use the tracking order cross server

  #Server 1

  RMAN > run {}

  immediate stop

  Startup mount

  allocate channels disk1 disk format='d:\backup\ora_d%_%T.bak'

  backup current controlfile

  database backup and archiving log

  }

  # Server 2

  RMAN > run {}

  allocate channels disk1 disk format='d:\backup\ora_d%_%T.bak'

  restore database

  output channel disk1

  }

  I have to create before catalog?

  (1) logs archiving is essentially a copy of your recovery logs, once it is filled.  Archivelog and db archivelog terms can be used interchangeably, but essentially in a database there is a redo log, then a newspaper archive.

  Archives Redo Log Management

  (2) what do you mean cross server?  Tell you backup a database on a server and then restore to another?

  If so then Yes, you can back up a database on a single server and restore to another.  If your database is in archivelog mode, then you don't need to stop the database first.

  http://docs.Oracle.com/CD/B19306_01/backup.102/b14191/rcmrecov.htm#i1007814

  Before you launch your start command to restore your database in nomount mode, restore the controlfile, set up the database and then do your restore, recover and then open resetlogs:

  SQL > startup nomount

  RMAN > restore controlfile from "xyz";

  SQL > bootable media.

  RMAN:

  Run {}

  restore the database;

  recover the database;

  ALTER database open resetlogs;

  }

  (3) you do not need a catalog of recovery, RMAN will use the controlfile.  However, if you have several database in your environment, you can use a recovery catalog.

• What was this last 9i database backup?

  Hi experts.
  
  I inherited a 9i database and I can't find the backup files to the local disk.
  
  I suspect that it is saved daily or weekly (a full backup), but how can I know for sure?
  
  Can I run a script or command to return some info?
  
  Thanks for your ideas.
  John

  Check the backup$ v. He can tell you when the database was finally out of backup mode hot - db backup if user managed backup hot. Ask your server sysadmin, he can know if the backups were put on tape - like via Veritas. Look for a crontab entry for a backup script. Is the database log mode archive - if not then...

  Or just forget and start again to make appropriate backups and archived logs recovery backups.

• Backup the database with archiving logs lost

  How can I get a backup of the database when all archive logs have been lost?

  So, it looks that you use RMAN to back up, since all the archivelog went. You can do

  RMAN> crosscheck archivelog all;
  
  RMAN> delete archivelog all;
  

  then make a backup.

• Recovery window retention policy removes the archive logs before backup?

  Hi all

  Oracle 11G on Windows 2008 R2

  This afternoon, I've changed my retention policy RMAN "RETENTION POLICY 3 REDUNDANCY"on RECOVERY WINDOW OF 3 DAYS RETENTION POLICY

  However, I checked tonight and after that my daily backup, all the archive before backup logs had been removed! So that means I don't think I can restore to any point in time, before my daily backup. All newspapers .arc were there after the backup. Then I tried another test and began the daily backup again. During the backup process, archive logs were deleted again! Now, I don't have any archives of newspapers...

  Is this good behavior OF RETENTION POLICY RECOVERY WINDOW? I thought that she would keep all the files needed for to restore me to any point in time for the previous 3 days. When I used a REDUNDANCY, with my daily backups, he kept 3 days of backups + archiving logs so that I could restore point-in-time at any point. How can I use WINDOW RECOVERY so that I can actually restore to any point in time for the 3 days?

  I wanted to change WINDOW of recovery, since I read that using the REDUNDANCY, it keeps only X copy a backup (so if I ran the backup 3 times a day, I would have only these 3).

  Thanks in advance.

  After a database RESTORE, Oracle tries to RECOVER a DATABASE.  He tries to 'find' the archivelogs for this phase in the location expected archivelog.  If they are NOT present in the location expected archivelog, it attempts to restore backups before applying them.

  Since your BACKUP... DELETE ENTRY deletes the archivelogs after that that they are saved, Oracle will have to use backups to recover the archivelogs.

• Archive log deletion with no backup of the archive logs

  I suffer from enormous size archive of the newspaper. In my previous post, I asked for help. I almost 480 GB archive log every day in our database of 11 2 under redhat linux 5.8 GR. Now, if you please help me in another case.
  
  If I take backup of archive logs and run delete archivelog everything until ' sysdate-1' with each backup database of day how it affects. " In my opinion there should be no problem in that I have the last incremental backup and recovery 1 days archive log in archivelog destination. If I do not archive log backups to how it will be different. Help, please.

  >

  Hello

  Sir, I know how to remove. But in my opinion delete up to sysdate-1 and taking no backup of the Archives of newspapers will
  no effect. Is in my opinion is right or wrong, that is the question.

  What I read in your original post, is that you take a daily incremental backup - Yes? I'm assuming that you also take
  a full backup on a regular basis (Sunday?).

  I was working on the assumption that the foregoing is available? I worked on a project where installation has been similar. We
  tested regularly backups - I hope that you do the same thing?

  What we used to do was FTP (script Unix - cron job - if you Google you will find Python or Perl to do the same thing - that is)
  what I wanted to, but was cancelled - very 1980, anyway) the archived redo logs on to a specific computer that holds only these files.
  After FTP "d - they have been removed from the server, freeing up space.

  Now, you say you have TB 0.5 per day - while more than a week, you will need a machine with ~ 3 TB of disk - if you can get a kind
  the scenario as this place and running, then you will have both your incremental backup and your archived redo logs for the last
  24 hours and the full backup with recovery archived records dating back to this full backup. You can also always archive on tape if
  suits. So, you will have redundant coverage - 'belt and braces' as the Americans say.

  But, to answer your question directly, "take no backup of archive logs have no effect" - that is true - it
  will not affect the operation of the database server, but if I were you, I would hang on to enough archived redo log to return to the
  last backup. That's just my humble OPINION.

  HTH,

  Paul...

• Archiving log backup RMAN

  Hi guys,.
  
  Can advise you on the syntax for the rman backup of archive logs generated in the last 2 days?
  
  Wouldn't be 1 or 2?
  
  Thank you!
  
  1 BACKUP ARCHIVELOG UNTIL ' SYSDATE-2';
  
  2 BACKUP ARCHIVELOG FROM TIME ' SYSDATE-2';

  Run the commands and see what is RMAN - it will show you what files it runs a backup of!
