RMAN backup control file

• RMAN-20033 control file sequence # too low & ORA-00230

  The two RMAN below errors occasionally I think that the cause is if an archive backup is running during a database backup, the controlfile is supported by both and can (but not always) cause these errors. The backup of the database is generally successful and that's just the backup controlfile who complains. I looked at how to avoid this, but it is not easy. Some backups of large database, especially for a full backup, run it for hours so archives have yet to be backed up and deleted.
  
  It might have started when ON CONFIGURE CONTROLFILE AUTOBACKUP has been set up. I don't know if this can be changed for backups of archive without affecting full/comú backups. Any ideas are appreciated.

  ORA-00230: forbidden operation: snapshot controls unavailable file enqueue

  Dear DBA2008,

  Please find the explanation of the error first;

  ORA-00230: operation disallowed: snapshot control file enqueue unavailable
  Cause: The attempted operation cannot be executed at this time because another process currently holds the snapshot control file enqueue.
  Action: Retry the operation after the concurrent operation that is holding the snapshot control file enqueue terminates. 
  

  There could be an enqueu for the snapshot controlfile and he should be released in order to continue operating.

  The other mistake is;

  Oracle Error :: RMAN-20033
  control file SEQUENCE# too low
  
  Cause
  the control file sequence is less than the one of the previous resync
  
  Action
  make sure that the right control file is used
  

  Thus, there could be another session which was try to resynchronize the catalog or simply access the snapshot controlfile.

  Can you connect please for the usual recovery with the connection string manager and type;

  RESYNC CATALOG;
  

  Do you still take the enqueue snapshot controlfile error?

  Hope that helps.

• Retrieve by using the backup control file

  Hello

  I was reading a book called Pro Oracle Database Administration by Darl Kuhn. There, under the theme of "The valuation of the loss of all control files", noted that all data files and control files are restored from a backup, because if we do not restore the data files the RCS in control files would be lower than the data in these scenarios files. Since online redo logs and archived newspapers is applied to the data files to roll forward in a current consistent state and does not roll forward to a control file.

  It is then mentioned to use 'recover the database by using the backup control file' then apply the logs (archive and redo if necessary).

  However I personally tested this script in a test environment and to bring all the backup control file could issue the same command as above and recover the database.

  My question is I know again and archives are applied only to the data files. So how does the control file are synchronized back when we do not restore the backup data files.

  Thank you

  If we do not restore the data files, the RCS in control files would be lower than the data files. Since online redo logs and archived newspapers is applied to the data files to roll forward in a current consistent state and does not roll forward to a control file.

  It would be incorrect you have determined. You can only restore the control files. You can manually create a control file and always do the restore.

  My question is I know again and archives are applied only to the data files. So how does the control file are synchronized back when we do not restore the backup data files.

  The control file is updated as well.

  See you soon,.

• Why open DB with RESETLOGS option after either complete or CAMILLE with a backup control file?

  Hi all

  I'm newbie DBA and totally confused when reading about the recovery.

  Why open DB with RESETLOGS option after either complete or CAMILLE with a backup control file?

  Using while will happen after we open DB using resetlogs in above mentioned mode of recovery.. .apart from resetting the log sequence 1?

  Kind regards

• We can to restore the content of a game without the backup control file?

  Hello
  
  I went in earlier today, a situation when someone (it wasn't me this time!):
  (1) a to back up a database and its archivelogs, in a compressed backup sets;
  (2) pushed the files to another server and
  (3) deleted everything on the server source, including ALL control files and control files.
  
  As he tried to recover the control file was missing and asked for help... I worked around the issue by using the snapshot controlfile he had forgotten (lucky me!)
  
  Now I can not remove from my mind the idea that I won't be so lucky the next time... I wonder if there is another way to work around this problem?
  
  Does anyone have an idea how to restore the contents of a backupset when we lack ALL control files and their backups? I tried to save the backup in the controlfile to a different database, but it does not work. I didn't find anyway to recreate a controlfile with a specific dbid without data files (and those who are in the backupset...).
  
  Any other idea? Best regards

• BACKUP CONTROL FILE

  Hi all

  11.2.0.1

  AIX 6.1

  I want to save my text control file as in

  SQL > alter system backup controlfile to ' / u01/a.txt ';

  But the result is not readable

  Why is this so the command

  SQL > alter system backup controlfile to trace;

  The result is readable, but it is very difficult to find

  Help, please...

  Thank you

  zxy

  It is certainly, ALTER DATABASE BACKUP CONTROLFILE (to not "changing the system")?

  Read the documentation... oh, Yes, you have made a habit of NOT reading the documentation.

  The syntax for a text trace file is

  BACKUP CONTROLFILE ALTER DATABASE to TRACK AS ' / u01/a.txt ';

• trap State of RMAN backup log file.

  Database: 10.2.0.2 enterprize edition
  Operating system: SUN solaris 5.10
  
  We will perform backups RMAN, level 0 weekend and incremental backups of level 2 and level 1 week. We will continually monitor the log through a HPOV tool file. This tool will send errors in the log file to the HPSMH ticket management tool.

• extract the rman backup data file

  Hello
  I want to search when logical corruption occurs in my database, so I want to extract my rman backup and test a file with db_verify.
  But I don't want to recover the database. How to extract a file without recovery and destroing database work?
  
  thnx

  You must perform the RESTORE in an auxiliary instance - preferably on another server.

  Note: If you do it on the same server, make sure that
  a. you do not connect to the same database instance
  b. you set NEWNAME so that the data file is extracted to a different location

  Hi Chris,
  Could do a and retry the backup.
  Can you post setting destination arch for EBIZ01PD ?
  The dbid for the EBIZ01PD and the EBIZRED would also be intresting .
  Do you use a recovery catalog?

• RMAN backup using control as repository via networker file

  Hi guys,.
  
  I use the control as the rman repository file. Currently I have this backup running at 20:00 every night:
  
  backup format full filesperset 4 ' / Data_%d_%U/' (database);
  SQL 'alter system switch logfile;
  SQL 'alter system archive log current';
  overlap archivelog all;
  backup format '% s_ %%t p_ arch_' archivelog all;
  delete archivelog all completed before ' sysdate-3'; "
  
  And the log backup archive running from 07:00, 11:00, 16:00.
  
  
  Have a few queries:
  
  1. understand that with the above, backup control files will also be included as RMAN automatically includes the control file and the SPFILE in backups of data file 1.
  So in all cases when my control file is accidentally deleted from the server, I always can I restore from the backup right?
  I think I need set the db first as a control the file id is my deposit. If the control is absent, it can identify the control file for restore by setting db IDs?
  2. my automatic backup of control is set to off. What is the difference between the control file backup taken by autobackup compared to 1?
  understand controlfile autobackup is good because it will automatically backup if there is no change in the db (as new file created, etc.). Any other difference?
  3.
  Plateforme BACKUP CURRENT CONTROLFILE
  ❐ a control within a file backup by using the CONTROLFILE CURRENT INCLUDE of the BACKUP command
  What is the difference with this backup from controlfile backup to point 1 and 2?
  
  4. Finally, if my control + bow + datafiles, redo file is deleted by mistake at 18:00. I've restored the control taken to yesterday 20:00 file. The control file consisting only of 20:00 and before backup information, how to restore the rest of the newspapers arch taken by 07:00, 11:00, 16:00?
  
  
  
  Thank you

  Since you talk about networker, I presume that you are copying backups from disk to tape as a separate order of networker. Do not forget to include the controlfile record as well during the copy on tape!

  1. Yes, you can restore the controlfile and spfile from the backup. But you will need to manually determine what backup piece contains the backup controlfile and spfile. (In the scenario where you assume the controlfile is lost, you cannot issue a BACKUP LIST to identify the backuppieces, so you will have files from search logs to identify the backuppiece!)

  2. a controlfile autobackup will be created in db_recovery_file_dest using OMF. If you do not have it defined, the controlfile autobackup is epxected to go in $ORACLE_HOME/dbs - although the location of the actual target can be dependent on version and platform.

  3. a backup BACKUP CONTROLFILE creates a separate backupset and backuppiece for the controlfile. In OMF, it goes in the backup directory, not in the AutoSave directory.

  4. without a repository, if your archivelog backups are on the disc, you can catalog THEM (i.e. run 'CATALOGUE START WITH /disklocation' command) in the controlfile you restorted to the backup from 20:00. You cannot catalog backuppeices tape is advicable to use a repository when you back up directly to tape.

• Restore the control file considerations

  Hello expert,

  Assumpition condition is:

  All the data files and the redologs are not damaged, but the controlfiles are damaged. We must restore the controlfile autobackup with the following command:

  RMAN > STARTUP NOMOUNT;

  RMAN > backup RESTORE CONTROLFILE AUTOMATIC;

  RMAN > ALTER DATABASE MOUNT;

  RMAN > RECOVER DATABASE;

  RMAN > ALTER DATABASE OPEN RESETLOGS;

  Use of rman RECOVER, DATABASE redo logs to roll changes forward to control files. Can you explain what changes can be included? (Currently I only have one example: we add the new data file once the backup control file.) So we need roll forward the changes to control the file on the new added one.) Other examples?

  Thank you and best regards,

  Tong Ning

  Examine the contents of the controlfile.  He has the list of data files, the list of the archivelog files and list of rman backups.

  Archivelogs would be saved in the controlfile so that they can be applied.

  What about backups?  Subsequent backups would certainly no longer be in the controlfile.
