Full backup with no archivelog

• full backup with archivelogs

  I tried to do an incremental backup of level 0 with archivelogs, it failed with the error messages says that cannot recognize the file C:\ARCHIVE\ORCL\4_1_684433700.ARC, the error code was ORA-19625. So I added "overlap archivelog all;" to the backup script and do it again.
  This time, he succeeded, but there is always something I'm confused. I created two folders to store the archivelogs, during the process, the archivelogs in the files were not deleted synchronously, for example arhivelog one has been removed from a file, while the same file in the other folder remained. Here is my backup script
  RUN {}
  ALLOCATE CHANNEL ch00 TYPE DISK;
  ALLOCATE CHANNEL ch01 TYPE DISK;
  BACKUP
  extra strength 0
  SKIP INACCESSIBLE
  TAG hot_db_bk_level0
  FILESPERSET 5

  FORMAT '\\dell090121\rman_hotbackup\bk_full_%s_%p_%t '.
  DATABASE;
  SQL 'alter system archive log current';

  # Note: During the backup of the database, RMAN backup process also the

  }

  Even if you have directories of archivelog destination two (or more), the clause of "DELETE ENTRY" in "BACKUP ARCHIVELOG."... "would be to remove only the archivelogs that he plays for backup. So, because the backup might read of dest_1 (for example), it would be archivelogs dest_1 but not dest_2. The backup is free to backup files in each position of dest and remove only what he has saved by default with 'REMOVE ENTRY'.

  However if you specify DELETE all THE ENTRIES, then Oracle removes all copies of the ArchiveLogs.

  Your backup command would be

  BACKUP ARCHIVELOG ALL DELETE ALL INPUT;
  

  where the first 'ALL' is ' all logs archived available sequences, but only 1 copy of each ' while the second 'ALL' is 'all copies of each archived log, supported by the BACKUP.

• RMAN backup with no archivelog mode

  Hi friend
  
  I made this backup several times before, to save a test database that is not in archivelog mode.
  My procedure are:
  
  
  rman target $ /.
  
  RMAN > run {}
  stop immediately;
  bootable media;
  backup format ' / u02/RMAN/%d_LVL0_%T_%u_s%s_p%p' database;
  remove obsolete;
  }
  
  But strange, now I have error:
  ORA-19602: no backup or copy of current file in NOARCHIVELOG mode
  
  
  Thank you very much

• full backup

  Hello
  I have create this shell script for rman for Oracle version 8i for full backup (database + controlfile archivelog):

  rman nocatalog <<EOF >> $LOG 2>&1
  connect target sys/password@sid
  run {
  allocate channel c1 type disk format '/backup_full/backup%d_DB_%u_%s_%p';
  backup database;
   sql 'alter system archive log current';
  backup format 'backup%d_CL_%u_%s_%p' current controlfile;
  backup format 'backup%d_AR_%u_%s_%p' archivelog all delete input;
  release channel c1;
      }

  Now I need rman script to Oracle 10.2.0.5 for full backup (database + controlfile archivelog).
  
  Is this right? Should I change?
  
  
  Thanks in advance!

  Hello

  Your script above looks perfect with the exception of '$LOG' which is not defined. But I prefer to add ORACLE_HOME and ORACLE_SID in your script and also change the format specifier "%u" "%U" while RMAN generates the uniqueness in the backup files. Here's the updated script for you.

  ORACLE_HOME=
  export ORACLE_HOME
  ORACLE_SID=
  export ORACLE_SID
  MY_PATH="/backup_rman_full/"
  export MY_PATH
  
  rman nocatalog <

• backup with rman

  Hello, I have several questions about rman.
  
  I have an Oracle RAC with 3 knots in Suse Linux Enterprise Server 10 on IBM's PowerPC, and I want a script for the backup of this database.
  
  My database is in archivelog and I multiplex that it again online connects two diferent locations
  Location 1 = >/u01/redo_log
  Site 2 = >/u02/redo_log
  
  Also, I have MUX logs oracle archived in two different places:
  
  Location 1 = >/u01/archive_log
  Site 2 = >/u02/archive_log
  
  I want a full backup of my database, for that, I think I have to configure somethings in Oracle rman like this:
  
  
  -Configure the backup to a disc (AREA of RECOVERY FLASH)
  DATABASE BACKUP AS BACKUPSET DEVICE TYPE DISK;
  
  -Backup of database and archivelog and delete all archive logs after backup. is true?
  DATABASE BACKUP AS BACKUPSET MORE ARCHIVELOG DELETE ALL ENTRIES;
  
  -Implementation of a strategy for retention of 7 days (I'm going to recovery all data from my database in 7 days)
  CONFIGURE RETENTION POLICY TO RECOVERY OF 7-DAY WINDOW;
  
  -Save our backup controlfile
  CONFIGURE CONTROLFILE AUTOBACKUP ON;
  
  OK, I want archivelogs auto removal in slot 1 (/ u01/archive_log) and 2 (archive_log/u02 /) when I have a backup of it, because I don't have a lot of space on the disk.
  
  My AREA of RECOVERY FLASH did not have a lot of space and I put a 7 day recovery window, then oracle delete backups obsolete or expired, IS TRUE?
  
  Well, I have the peripheral band but connect directly to any of my 3 knots, because I do not have the drivers for IBM PowePC, so I want to periodically copy to another server, and then copy the FRA in this new server Ribbon. I need before Oracle removes the obsolete backupset, is true?
  
  If I save all my backupsets to Ribbon I will be can restore all data to 3 months ago?
  
  Thank you very much
  
  PD: Excuseme, but I'm Spanish and my English is terrible, horrible!

  The RECOVERY WINDOW is part of the RETENTION STRATEGY.

  If you have defined a RECOVERY WINDOW of 5 days and you daily full backups or full backups every 2/3 days, over 5 days of backups would be OBSOLETE.
  However, if you perform only full weekly backups, full backup of last Sunday is not obsolete (even if it seems to be beyond the 5 day window). Oracle expects that the backup is available.
  However, if you moved it off disc then you have to manually restore this backup to disk first before the DATABASE RESTORE is on it.

  Therefore, to answer your question: even if the RECOVERY WINDOW is 5 days, if my last (or 'later') full backup is 6 or 7 days ago, that the backup is NOT deprecated by Oracle and is used for the RESTORATION. Of course, Oracle then, in my example above, apply to an incremental backup on Friday and then updated by ArchiveLogs on Friday has left.

  (Similarly for the full backup being restrained, ArchiveLogs are also retained by Oracle and not obsolete, because they are needed for the revival of this full backup)

• BlackBerry software how full is a full backup?

  Finally, I will send my Dev Alpha return and I want to back up all data on the device to restore it once I get my THE Z10, but now I wonder how full a full backup with BB Link is actually. BlackBerry links speaks only of Application data, media and settings, this includes contacts and text messages? I know that the micro-sim card can store messages and contacts, but how can I be sure that they are on the sim card and how can I save them with link BlackBerry (just to be sure)?

  I got my THE Z10 now, and I can confirm that after loggingin with my BB ID all my contacht have been synchronized live, no backup necessary! For other stuff, you obviously still need to restore the backup.

• RMAN full backup - size SPFile Total 0.00 K

  Hello, I do some tests and I need help to understand if there is something wrong in what I'm trying to do (a full backup with RMAN, DB is 11 GR 2).
  
  If I perform a simple full DB Backup, all past file and it completes successfully. No errors.
  
  Controlfile Autobackup is enabled, so I expect to find the control file and SPFile included in the backup, too.
  
  But if I go to Console 'EM-> availability-> backup reports

  Looks SPFile size on backup is '0' and not what I was expecting (SPFile is actually being used and it is not empty).
  
  Should what kind of verification I do to see if everything is OK? Maybe a non-destructive.
  
  Thank you very much!

  Hello R,

  (1) the SPFile will be restored in a custom location / name of my choice ("spfile_restore.ora")
  which may be different from the ACTIVE SPFile

  I would say that must be different from the current spfile...

  (2) the SPFile ACTIVE will always be in place and will always be that "in use" even after restoring

  Correct the restored spfile will not be part of any oracle process.

• RMAN how to handle simple full backups every day with the archivelogs

  
  

  
  

  Hello

  My use of Oracle DB is about 200 GB on a file system 1 TB from a NetApp file server. (i.e. 20% currently use)

  I'm not so attracted to use the RMAN catalog for the love of simplicity.

  Also, I have an affinity to run a full backup "Instant NetApp" every day, without running all the incremental backups.

  My snapshots of NetApp have a framework for the retention of 7 days.

  I think to implement a RMAN full backup script that includes the following to run every night:

  Run {}

  delete archivelog all;                    (to clean up the archive logs that are accumulated for each day)

  backup database;                          (for a full backup every night)

  }

  This will be a good idea?

  Will this coverage to back up all that I could restore if there is a problem.

  
  

  Part of the great mystery for me is on the restoration of the data that is generated during the execution of the "backup database" command in the RMAN.

  Any advice would be appreciated.

  Thank you!

  -Steve

  If you perform the backup in this order, you will get in big trouble.

  It is preferable to run the backup as follows:

  (1) the following parameters, you have to do only once:

  configure backup optimization

  Configure retention policy to recovery of 7-day window;

  Configure controlfile autobackup on;

  (2) backup every day:

  backup database more entered archivelog delete;

  delete noprompt obsolete;

  unrecoverable report;

  RMAN automatically takes care of cleaning the old backups<7 days="" and="" saved="">

• My 2 TB TC is full and will not back up. Yet, I have only 1 TB of data on my laptop. Note that I've reformatted the laptop since the last backup with a clean installation of El Capitan.

  My 2 TB Time Capsule is full and will not save. Yet, I have only 1 TB of data on my laptop. Note that I've reformatted the laptop since the last backup with a clean installation of El Capitan.

  I bought a 2 TB external hard and have used Time Machine to back up. But I also use my time Capsule, which I save wireless.

  Any suggestions on getting my TC back up?

  One suggestion would be to copy all existing backups that are now on the Time Capsule 2 TB hard disk. Then, clear the TC and start over again with new backups.

  A more expensive option... assuming you want to keep all old backups on the TC... would be to add a new TC and start backups goes in this direction.

  Another option... If you do not need to keep all old backups now on the TC... would be to erase the TC and start over again with new backups. The benefit of doing this would be that no new material will be necessary, but the downside would be that you lose your old backup history.

• RMAN backup with a missing archivelog.

  Hello
  
  I backed up my database yesterday after that you guys helped me to solve some problems I've had on this subject. I have used RMAN with the following command in an execution block:
  
  * run {*}
  allocate channel t1 type disk;
  backup current controlfile;
  backup database;
  delete any backup archivelog entry;
  output channel c1;
  *}*
  
  At the end of the operation, RMAN indicates that archivelog is missing, and he couldn't find it. Therefore, recover the operation may be compromised. Now am confused because I don't know if the command executed successfully or not and how to fix the missing archivelog.
  
  Here are all of the output of the operation with the error message:

  Thanks in advance.

  Adomi,

  It is sad to see that you are still RMAN in 8i mode where you are on 10g.

  The script is bs, sorry

  Run {}
  allocate channel t1 type disk; -not required
  backup current controlfile; -not necessary, as this is already done backup of database
  backup database;
  delete any backup archivelog entry;
  output channel c1; -not required.
  }

  If you have autobackup controlfile, you might just

  backup database archivelog

  and be done with it.

  Like you didn't made a RMAN backup from the start, should have read your archivelog backup statement

  ARCHIVELOG backup all Skip inaccessible delete entry.

  Once successful Oracle shouldn't the archivelog has more need, and you should make a second backup without the skip inaccessible clause.

• Full backup to optimize backup RMAN

  Hi gurus,

  I wanted to implement the functionality of rman backup optimization. I did a little test to verify its use and not found helpful whenever I do a full backup to backup all data files and nothing is ignored.

  According to the ORACLE notes as below, ideally, once I backup the database, the backup else should jump not all files.

  
  

  If you enable Backup Optimization and then the BACKUP command ignores backup files when the identical file has already been saved on the specified device type.

  
  

  Please note that it's my test server and no connections are on the DB. Listener is broken. If no point of change Yvert. I'm missing here something?

  Hi Tom,

  Well well, then that contradicts what oracle mentioned in the docs?

  Not at all.  It does that contradict your understanding of what constitutes a data file "changed."

  Also, I pulled data backup and not backup tablespace.

  Is not serious. The principle is the same.

  Also check your statement my understand that if there are 100 files of data and rarely used, Yvert will be updated for each of them?

  If they are not unalterable, then Yes.  That's how oracle ensures consistency between the data files.

  Kind regards

• Archive newspaper vs. Full Backup Concept

  Hello
  
  I just need some clarification on how backups and Archives Records work. Lets say from 13:00 I have archive records 1,2,3,4,5 and then I perform a full backup at 18:00.
  
  I take then generate logs archiving at 18:00 to get newspapers 6,7,8,9,10. Then, I stop at 23:00.
  
  If my interpretation is correct, the archive logs should allow me to restore oracle to a point in time anywhere between 13:00 and 23:00. But if I have only the full backup, then I can only restore to a single point, which is from 18:00. My understanding is correct?
  
  Archive logs only applied to data files during backup or only during a restore? There is no archive newspaper applied on the fly.
  
  Thanks in advance.

  Thanks for the great explanation! If I can do a restore time to any time point since the data changed files have been written (or when I have the last set of data files backed up more archive logs). What you say, I can force the data files to write about recovery logs (by a control point with 'alter set archive current log' or 'backup database more archivelog'), and then I can delete all archive logs have an SCN less than the SNA control point on the data files. Is this true? It would be for the purpose of preservation of disk space.

  Hello

  See this example. I hope this explains your doubt.

  Given the 10.5.8 to 10.6 Snow Leopard upgrade.  Meet the Intel/memory minimum requirments.  After a full backup of course.  Anything I should be aware of before trying this?  Possible to the functions/effects?  My data (mp3, photos, documents, etc.) will not be affected?  I also have Windows for Mac.  It will not be affected?  Recent browser performance is untenable in weeks.  Safari 5.0.6.  Now even my Firefox is fact-zo.  Process seems simple enough, but thought I would ask a preview as many reviews on here seem to go anyway in regard to recommend it.  Thought that I have gathered a few comments before the trigger (or not) thank you to all those wh

  Just to start with this one:

  I also have Windows for Mac.

  I assume you mean that you run Windows in a virtual machine such as Parallels? If so, the machine virtual peut must be updated.

  When you install Snow Leopard, make sure to choose the option to do a custom install, so you can select the check box for Rosetta, or it will not install and PowerPC applications will not run. Not a huge deal if you miss. The first time you try to run a PPC application if Rosetta has not been installed, OS X offers to download and install it for you.

  Firefox works under Snow Leopard, which is the oldest version of OS X Mozilla always supports. Safari installed with SL will remain grossly outdated and should not be used.

  Nothing will happen to your documents, although I can't say with certainty that all the apps from third party that allows you to open will not be updated. They can. They cannot. For example, Office 2004 will run as long as Rosetta is installed.

• Adding redundancy backup with time Capsules

  Are there problems associated with adding a second time Capsule to my system in order to add additional redundancy and safety of my backup options? I have a MacBook Pro and a single Capsule of 3 TB. I am looking for a non-Cloud option add extra security while maintaining the automation of the OSX TimeMachine.

  Adding a second Time Capsule works perfectly.  After that Time Machine performs a full backup of your Mac (s) on the new Time Capsule, it automatically alternates between two time Capsules backups.

  If you have the possibility of adding a USB or FireWire drive directly to your Mac, which would be a bit better set up in terms of reliability of time Machine, but probably not very convenient if you have a laptop that is moving all the time.
