• Creating a database with only the RMAN backup

  Hello
  
  I have a full backup of a database (10.2.0.1) of 10g RMAN in RHEL5 server. This backup has only the backup piece does not SP. and the control file. I want to create a new database with this backup in a new server. Is this possible? How to go further?
  
  Kind regards

  Hello

  Refer to this that you can take a look at this http://shivanandarao.wordpress.com/2012/04/19/duplicating-primary-database-to-a-new-host-without-connecting-to-the-primary-database-in-oracle-10g11g/

  RMAN automatically backup spfile and controlfile in the backup of the data file 1 (SYSTEM datafile). So you can restore them from the backup piece which is to have the file system data.

• Suddenly slow rman backup in oracle 11g

  Hello
  
  from yestarday suddenly rman backup incremental to take more than 3 hours, what was supposed to be 20 mins
  
  nothing has changed since the database, so how can I find the cause of the delay
  
  Thank you

  What is the version?
  You can trace the order and activate 10046 trace as sql regular... And analyze using tkprof.
  You can refer
  RMAN backup is very slow, selecting from V$ RMAN_STATUS [375386.1 ID]. This note cannot be directly related
  to your problem, but there are commands for activating 10046 trace in that.

• Oracle 10g - Cross - Platform Database Portable (with or without RMAN?)

  Hello guys,.
  I am currently on a project of databases oracle migration from one platform to another platform (both platforms are on the same boutien):
  -> For Linux 64-Bit of Windows 64-Bit
  --> In HP - UX 64-Bit to 64-Bit AIX
  
  All databases are on Oracle 10 g (10.2.0.4) and I tested two different ways:
  
  (1) the 'official' way with RMAN CONVERT DATABASE
  http://youngcow.NET/doc/Oracle10g/backup.102/b14191/dbxptrn002.htm#CHDEEEAG
  
  (2) ' copy and paste '.
  -Copy and paste the database files
  -Create controlfile manually on the target platform (with the help of "backup controlfile to trace" source platform)
  
  
  Both methods work well and the migrated databases test work fine.
  
  Now, I wonder why there is a command "RMAN CONVERT DATABASE", if it is possible to copy and paste the data from the files and perform two steps manually later.
  The "RMAN CONVERT DATABASE" takes time and you have to copy the output files RMAN for the target platform.
  
  Is there a special reason why you need the "RMAN CONVERT DATA base"? The "RMAN CONVERT DATABASE" change things in the files of database internally?
  
  Thanks and greetings

  So my question is if there is a special case in which you use the RMAN with 'RMAN CONVERT DATABASE' instead of just 'copy & paste' If you stay on the same "endianness"?

  Database convert RMAN is the only supported way to 'move the database' on platform. Data files have some platform specific headers, and the conversion of RMAN prepares these data files (in particular regarding storage space containing ROLLBACK, mostly the TBS SYSTEM segments and CANCEL).
  The script also runs the script utlirp.sql in mode UPGRADE and utlrp.sql in NORMAL mode.
  So, I would avoid using a simple copy of the data files, I already tried for the objective test (HP - UX-> AIX) and encountered a few errors ORA-600 which I did not with conversion of RMAN.

• RMAN backup with log archiving

  Hello
  
  I'm using oracle 11G (11.2.0.1). My open database and I'm using the RMAN command to perform a backup hot below. My doubt is the reason we have the backup of the database to archivelog more? What is the use of the archivelog backup because the archivelogs will keep generation while the database is open.
  
  RMAN > backup the database archivelog;
  
  Kind regards
  
  007

  I agree with Oviwan. You must archivelogs in the recovery database to the last second. If you have the base of mission critical data, then you must also add redo log members on different disks.

  And I also suggest to run command before backup below.

  RMAN > sql 'ALTER SYSTEM SWITCH LOGFILE;

  You can remove the logs to archive that are saved.

  RMAN > delete any backup archivelog entry;

  Also, I suggest to backup database and Archives journal separately.

• RMAN backup with the smallest size of backup

  Oralce 11g 2 on Redhat 5. Disk space is our the tighter resource, and we want an incremental backup with Level0 Sunday and level 1 every day of the week and on Saturdays. I'm using the comamnds to do the job

  --Sunday
  backup incremental level 0 tag 'level_0' database plus archivelog;
  --Other days
  backup incremental level 1 database plus archivelog delete all input;

  I don't think that it is the best practice or produce smaller backup files.
  
  What are you comments and opinions. Thank you

  RMAN backup except for the backup copy will only backup blocks used, which is quite efficient. Backup incremental level 1 are set by default and the smallest of the incremental backup.

  However, you can enable compression reduce the size of the backupset (Oracle 10 g and more). You can also enable the block track the changes in the database only once, so that backup incremental level 1 do not need to analyze the data files for the changes - this allows saving a lot of time and IO.

  SQL > ALTER DATABASE ENABLE BLOCK CHANGE TRACKING;

  RMAN > run {sql 'alter system switch logfile' ;}}
  RMAN > BACKUP AS BACKUPSET INCREMENTAL LEVEL 0 COMPRESSED DATABASE MORE ARCHIVELOG DELETE ALL ENTRIES;
  RMAN > ACE COMPRESSED BACKUPSET INCREMENTAL LEVEL 1 DATA BACKUP MORE ARCHIVELOG;

  I would prefer not to delete the archivelogs after each incremental backup of level 1 in order to make a point in time recovery without the need to restore the archivelogs.

  And don't forget to:
  CONFIGURE CONTROLFILE AUTOBACKUP ON;

  I hope this helps.

• Creating a new controlfile with RMAN backup data files

• RMAN backup optimization CANCEL 11g

  Turkel

  Hi Turkel,
  Space used to cancel is also linked to the undo retention implementation.
  As it seems do you an update of test and perform backups on:
  -14: 24:37 (-> 25 M)
  -14: 25:41 (-> 25 M)
  -14:33:59 (-> 11 M)
  -15: 28:43 (-> 600 K)
  The first two backups are probably still in the retention period to cancel the update.
  The third backup shows a cancellation partly empty (is your setting 900?).
  The last falls outside the period of retention for the update, resulting the small size of backup.
  Kind regards

  Hi, I have to log on to the database server and map a network drive. I create a folder named rmanback and run rman to back up the database. However, it fails with the error

  By default Oracle (database, listener) services to run under the LocalSystem account internal. This account is not allowed to write on disks shared for security reasons. And it is this account that makes the RMAN backup, not the OS user you are connected. Redefine the Oracle services, that they run under an administrator account (if you are in a domain, use a domain administrator account), see on metalink:

  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.

  Perhaps it works for your condition.

  RMAN > backupset backup is complete before ' sysdate-1';

  Kind regards

• RMAN backup with archivelog (advantages/disadvantages)

  When you do a "backup database with archivelogs" where rman stores the info contained in the archive logs. If I do a backup as I have to still keep logs archiving on disk? This increase in time to make backups? I have a few databases of production that are close to 500 GB. Ask yourself what advantages/disadvantages do a backup in this way.
  
  Thank you all!

  Stored information in the archive logs (what you were asking, but probably not what you mean) is stored in archive logs. Backups of these logs are stored in a backup set. Information on newspapers are stored in the control file.

  You supported their top, right? Archivelogs are not actively used by the database running, right? If you don't remove them after that only they are saved, let me know who you buy your storage drive, because I would like to buy stock in that company.

  No matter what you do "increases the time to do' vs do not do something. (More effective SELECT statement is not executed). The question is that it has a concrete and measurable performance degradation which is intolerable to my organization? The answer probably 'no '.

  Are the pros, you can recover your database.
  Disadvantages are, you cannot recover your database.

  And it seems that we must point out that the housekeeping of your archivelogs can and should be handled by rman, not outside of it. Watch "archivelog backup not saved n times" and "delete backup archivelog n times" and other variations of 'backup archivelog' and 'delete archivelog.
