Recovery of control files lost.
Hello
I run my database in noarchivelog mode. This is a database of test of pure on my laptop at home.
Scenario of
1 copy the existing control to another location on my PC.
2. open the database and made some changes to the database (create tables).
3. deletion of the existing control files.
4 database could not be mounted.
5. restore control of the location of backup files.
6. the database is mounted under the mat.
7. recovered using backup controlfile but could not recover.
8 save the control to trace file
9 a created control file by changing the trace file
10. fixed using the database backup, applied to newspapers and recovered control file.
My question is why could not recover the database in the first case of a copy of OS control files, but could recover when I manually created control file.
Thank you
Hello
1. as indicated, you are in noarchive logmode (kind only OLR is used for recovery)
2. now, you closed the database mode compatible and prior (in the db is running), you have taken a backup.
3. the backup controlfile doesn' the changes you have made
4. now, when you start the instance and the restoration of the controlfile back, there he changes (blurred) didn't know where in the end. The CNS is lower compared to datafile_header
5. now you have activated 4 times files newspapers is getting crushed and change is lost at the level of the RSC and it's already emptied to the data files and controlfile (YVERT updated)
6. then, do you think you are looking for old OLR changing
Specify log: {=suggested | filename | AUTO | CANCEL}
/u01/app/oracle/oradata/testdb/redo02.log
ORA-00326: log begins at change 939321, need earlier change 918423--- here the log is looking for earlier one
ORA-00334: archived log: '/u01/app/oracle/oradata/testdb/redo02.log'
So he could not be able to open.
7. When you created new controlfile, he succeeded, since your last stop was in line. so the controlfile read all the headers of data file all in harmony, let me open it.
Cause is switching to log files
-Thank you

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
My db instance running with control 3-files if my 2 controlfiles are lost due to disk failures... is - this run of the instance or an abortion?
I have my doubts regarding... If we put 3 controlfile in INIT.ora... like CONTROL_FILES ='/... Control1.ctl ',' /... Control2.ctl ',' /... Control3.CTL'.
I think oracle server process written information updated at the same time 3 controlfiles right?... If she writes... While the loss of 2 controlfiles why not abort instance occur?
Please let me knowuser603328 wrote:

Please let me knowIf you're on a * nix environment, it files are kept open by the oracle process even if they are deleted. This may be a reason that you may not have seen the instance be abandoned immediately. Once you close the database and could therefore stop the process, next start would happen not because of control files is not available. So have you tested this on windows or linux?

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 file has been lost no control backup file avilable in db
Hello
Control file has been lost no avilable to control file backup in the database how to recover the control file and recover the database.Hello
If you have backup controlfile to trace, then you can follow the action plan below
1)
SQL > startup nomount
SQL > execute script
SQL > restore database using backup controlfile;
sqL. ALTER database open resetlogs;Note: datafile header SNA will be stamped to controlfile one
If no backup of the file available trace control, then perform the Ridge below the action plan
Any other database
sqL > ALTER DATABASE BACKUP CONTROLFILE TO trace;
SQL > show dumpcheck in udump
now, you must modify the controlfile and do file parameter etc... You can use alerts to the same log
SQL > execute script
SQL > restore database using backup controlfile;
sqL. ALTER database open resetlogs;You can check the link below also

strategy of redo and control files
Excuse my ignorance in this area (not oracle or a DBA), but from a risk perspective, I read his best practices for storing a redundant copy of recovery logs and control files on a separate disk / server - for redundancy.
However, if the server is a server database physical, with local storage (in which case files of database and the oracle software resides), no configuration of cluster if the server dies a sudden death, then what exactly are the newspapers redundant recovery and control of files will save you of? Is it to minimize the loss of data, or else (told you I wasn't a DBA or Oracle guru). If you back up your recovery connects dialy then I don't know what exactly the redundant copies really are for/record you leave?
So if the server dies (and the storage is still ok) and then transport the storage to another server and you are in business again. Multiplexing or not does not change your ability to use another server.
In a disaster situation, where you lose the server and the storage is also lost, so you have to go to a backup and multiplexing saves you from what it is because the backup has only 1 copy of the controlfile and archivelogs.
If you get a logical corruption (IE a bug in the software) with controlfiles multiplex, then you're still screwed because all controlfiles are physical copies of each other, so all controlfiles have the same corruption. In this case, you must go to a good backup of the controlfile.
Multiplexing allows you to save when you get corruption Physics (due to the corruption of storage) of your command multiplex or multiplex redo logs file, and so you can use the good copy of the file control or redo logs to continue without losing the validated data.

restore / recover the control file
Hello
in 10g, I lost all the files of ctl and I want to restore/recovery of backups RMAN.
Oracle documentation:
After that I should publish any statement to RECOVER or change the editing of the database and alter database open would be enough?6.4.1.4 Restoring a Control File When Using a Recovery Catalog Restoring a lost control file from autobackup is easier when using a recovery catalog than when using only the control file to store the RMAN repository. The recovery catalog contains a complete record of your backups, including backups of the control file. Therefore, you do not have to specify your DBID or control file autobackup format. To restore the control file, connect RMAN to the target database and the recovery catalog, and bring the database to NOMOUNT state. Then issue the RESTORE CONTROLFILE command with no parameters, as in this example: % rman TARGET rman/rman CATALOG catdb/catdb RMAN> RESTORE CONTROLFILE;
Thank you.
Is there a complete senario anywhere?The restoration is correct.
Please see the following:

How can I get out of this confusion?Looks like your scene preclone directory is not correct (corrupted), and I think that it is because preclone does not run successfully.
Either you follow the steps described in the following notes to change the existing to a new undo tablespace or run preclone and copy the files again.

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

(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.

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

Hi Ritu,
Google is a very rich source of information...
I found this article in Hemant which I suppose is very informative for you... Read everything including the comments!

Syslog does not display the IO error.
I followed the steps below to solve the problem.
1] stop the database
[2] restore control01.dbf to the backup location.
[3] mount the database
[4] recover database until cancel[5] Alter database open resetlogs.
Also, takes a full cold of RMAN backup of the database, the multiplex control files and recovery logs.

ORA-00338: 3 log thread 1 is more recent than the control file
Hello
I met the error ORA-00338 while performing the recovery of incomplete data:

ORA-00312: wire 3 1 online journal: "+ DG_REDO/dbase/onlinelog/group_3.267.814820795".
Complete recovery manager.
I made this recovery on oracle 10g, database of ASM.
1. What are the possible causes of this error ORA-00338?
2. This error occurs at the beginning of the media recovery, RMAN is applying logs archived. If RMAN does newspapers "Online REDO" after applying "archived" logs required for recovery or in front of them?
3 rman is how this journal in line 3 is more recent than the control file? How can I me SNA of the journal online & file control in my environment?
Here are some details related to checkpoint scn / change # info. I found in my environment:
Before recovery:

v$ datafile_header: 642935

Then, using the SQLPLUS command line, issue a RECOVER database with the HELP of BACKUP CONTROLFILE until CANCEL. See which he records guests for and monitor messages in the alert.logHemant K Collette
