Check out my video tutorials:
http://kamranagayev.com/Oracle-video-tutorials/
Here are the steps to follow for you, try running it by yourself (in the test database):
-Take full backup of the database and configure RMAN to do an automatic backup of controlfile "CONFIGURE CONTROLFILE AUTOBACKUP ON".
-Remove all the controlfiles
-Use the command 'Restore automatic backup controlfile' to restore the controlfile autobackup
-Use the command 'recover data' to recover the database
-Open the database

Hello
How knowledge/check if the RMAN backup was performed using a current control file or database catalog? I mean RMAN prompt or sqlplus is it possible to know.
Thank you
You're welcome my friend
You can see them using two methods.
as I mentioned above, you can see them connect to the catalog database and you can query using the view that I sent
http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmreprt.htm#BRADV89601
the other method is the list command, you must use the list command after connecting using rman "rman target / catalog cat_user/cat_pass@catdbtns" command
http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmreprt.htm#BRADV8136
Check the value of the control_file_record_keep_time parameter. The default value is 7 days. in the output of the list command, if you can see the old backups to the value, you must be sure that the backup information comes from the catalogue database
SELECT * FROM parameter $ v where name = 'control_file_record_keep_time '.
an example of command list
the list of completed database before backup ' sysdate-10'.

I don't do enough laps to be able to cite details on the commands to use (and I often find myself using the command line recovery after that file of rman restore, but the steps you need must be)Take a copy of security of the data current, archived and online redo log files.
Restore the backup control file, data files, and archived recovery logs
Recover the database by using up to cancel backup control file
You have to do 'create datafile' bit as the collection hits the 'missing file' bit
You will need to provide the names of the archived and log files online redo recovery reached their

Control to the RMAN catalog file
Dear friends,
Now my RMAN backup is running using the control file. How can I change the catalog?
Please guide me.
Thanks in advance.If there is no drawback application RMAN catalog, then I guess I do it with her.
Like when I want to recover the database in a new server with the backup and so on... >
The downside is the maintenance you need to do for the catalog. He had some performance issues with the catalog in previous versions, but I think he's fine now.
Do I need to back up the RMAN catalog or back up separately in addition to the backup of the database?
Could I lose the catalog if I lose my database
Just save as regularly as you can afford. RMAN or export. Losing the catalog is a hassle but not the end of the world.

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 enqueueDear 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 usedThus, 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.

Thanks in advance.Hello..
Do you have free space? If Yes, then you can try: -.
RUN {}
SET NEWNAME for DATAFILE 3 to ' / u05/oradba/U1234/dbfile/U1234_sysaux01.dbf';
RESTORE THE 3 DATA FILE;
DATAFILE 3 SWITCH;

Hi all.
I really need your help on this:

(2) database does not start, don't get database.

Verification of MOS Note: 435436.1 I must:
(1) to restore a backup of a controlfile and recover
OR
(2) to recreate the controlfile
OR
(3) restore the backup data and recovery
It is a database, that I was not, up to now administer. But:
(1) I tried from the database with addressed controlfile (the one located in FRA). No luck. (Create pfile from spfile / startup pfile)
(2) the database is not mount / open. It hangs on the editing process. So I can not issue an alter database controlfile to trace.
It seems that my options are:
(1) manual creation of controlfile with open resetlogs option. This option is viable, but risky if we miss a datafile or something GOLD
(2) restoration of RMAN backup. The thing is that the most recent copy of automatic backup of controlfile is since a few days early (4 / 5 days).
I found this link: http://gavinsoorma.com/2009/07/rman-recovery-from-loss-of-all-control-files/
The procedure seems easy, but since this controlfile is not in the current SNA of database (data files, etc.). I'm not sure it if it would work.
So in short, I think I have an automatic backup controlfile and it's OK. but a little old. I can restore from this copy of CF?
Please I'm pressed real here, so help will be greatly appreciated!....
Thanks in advance!
Best regards, Luis...!
Hello
It seems that my options are:
(1) manual creation of controlfile with open resetlogs option. This option is viable, but risky if we miss a datafile or something GOLD
(2) restoration of RMAN backup. The thing is that the most recent copy of automatic backup of controlfile is since a few days early (4 / 5 days).
It seems that you have few options,
In my opinion, you should start with option 2), but you have logs archived redo and all and all the backups of catalog and perform a restore.
After, if not works, you must manually create the control files, but you are right, you must carefully on all the data files. Here a log generated in the last level 0 RMAN backup could help you, don't forget the newspaper are all entries of data for backup files.
I wish to have more ideas to help you, but I have no other.
I hope this helps.
Kind regards

QUESTION: Do I need to restore a full database to be consistent?
=====================================================You don't have to restore the full database. You just need to restore the backup controlfile and restore the database.
The steps you mentioned are good restore the controlfile. After recovery, you must open the database in resetlogs.Also, you can take a look at this http://neeraj-dba.blogspot.com/2011/04/loss-of-control-file-in-various.html

Hi all
9i
RHEL5
I have configured for the main database and emergency dataguard.
I want to create 3 database on another server in restore RMAN backup taken of database primary 2 weeks ago.
I then want to apply any archivelogs succeeding to make it current.
My question is, can I get the file of current mode control ensures to restore my db from backup primary RMAN?
Current control for the primary and standby files the same? Just in case, I'm switching to the db backup?
Thank you very much
JC
Yes, because the control files are interchangeable between the databases and relief.

ORA-19838: cannot use this control file to open the database
Dear all,
While making RMAN cloning, we are facing problem,
SQL > alter database open resetlogs;
ALTER database open resetlogs
*
ERROR on line 1:
ORA-19838: cannot use this control file to open the database
Concerning
Villi Kumar
Dear all,
While checking the database,
Control the name of the database file is PROD
In the instance, database name is TEST.
So we took the PROD and edited control file trace file based on the TEST environment.
Then run the script published in the TEST database trace file.
Now we can open the database by using below command
ALTER database open resetlogs;

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,.

Understanding of RMAN command file
Hi, please can someone put me right as I am confused with RMAN concept. (using 11.2, AIX, no catalogue)
Backup database more newspapers to archive and my DB is saved. I also have autobackup controlfile on. Ive done many restorations of test in this way when the data files are missing or needs to get back to a point in time.
As a test, I renamed all my files from control and then did a restore. I then restore the control file which I am starting from the automatic backup location. However if there is no autobackup then what? Where can I get my control record of?
Of the "backup database" command not actually backup control files? I always thought that a backup has been incomplete if the control files were not backup up.
Please can someone clarify this?
Thank you very much
Adam
However if there is no autobackup then what? Where can I get my control record of?
That's what I do all my backups: don't configure CONTROLFILE AUTOBACKUP ON, and I always explicitly backup backups of database/archivelogs after controlfile (BACKUP CURRENT CONTROLFILE): in this way, I always know what controlfile to restore.
DATABASE BACKUP command includes the backup controlfile anyway, but I prefer my name so that I can immediately identify the backup controlfile.
