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
Kind regards

(a) old version of data through rman backup files

(c) Backed archived redo logs
(d) recovery archived logs that have been recently generated
(e) current online redo logsTherefore, you should be able to bring back the database in the State wherever it was when you made the abandonment.
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
(although, presumably, you could leave copies of the logs stored in the default location)Concerning

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

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?

Incompatible control file and the data after the backup files
The company that I work has servers where some components are new more, so have a backup in the event of hardware failure. If we intend to do some clones of 1:1 of the current servers to change them in case of emergency. As most of the necessary data is not volatile and we reset stuff in any case, there is no need of replicaton, replace an old version of the database works very well. Now we could not easily get substitutes for our old material, so we had to set up new machines. And that's where my trouble starts, because now I had to actually set up the system and the database rather than do a simple copy of byte to byte. I'm mainly a programmer, using Oracle of 'other' side, but as our DBA is yet to come and the work must be done now...
So I did some reasearch and decided to do a normal backup of the cold. I have dumped the controlfile, copied data and configuration files to the new server and read the prompt SQL (no mistake there) control file. After some initial hiccups with the system (memory, etc.), I was finally about to start the database, only to get an error ORA-01190 ("1 database or control file is from before the last RESETLOGS").
I guess I did is a bad thing when you restart the database (used the wrong part of the control file) or when the copy of the data. The original data have split two readers for simplicity and logical, I copied their entire contents. So maybe I don't not copied to little but too?
As I said in the introductory paragraph, I'm not a DBA, but I'm willing to learn and listen. I don't expect a complete solution, but some guidelines when to look and what to avoid. Any help on this would be appreciated.Currently, there are some points need clarification,
1. you don't need to re-create the control file, if you have a clean shutdown database and copied all the files at the same time (data files, control files etc.)
2. If you stop DB, copied files of data but do not copy the control at shutdown file, you must re-create the control file.
3. the error ORA-19909 suggested you resetlog prior to recovery.
ORA-19909: string data file belongs to an orphan incarnation
Cause: The data file specified has been restored from a backup that was taken during a period of time that has already been abandoned by a resetlogs operation or Oracle cannot identify what incarnation of database file belongs. The alert log contains more information.
Action: Restore a backup of this file that belongs to the current or a previous incarnation of the database. If you use RMAN to restore, RMAN automatically selects a good backup.4. it would be better that again follow you from scratch the article.
for example,.
Copy the files you did copy over the data base to the bottom of the old server,
modify the control file creation scriptRECOVER DATABASE USING BACKUP CONTROLFILE;
ALTER DATABASE OPEN RESETLOGS; -

You have restored the old control file while your data files are recent. Restore the last control file and then recover your database to open it.

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.

Hello
I try to simulate recovery scenarios. My Oracle database 11g is configured with two control files. I stopped the database and a corrupt control files by editing with random characters using a hex editor. When I started the database, everything is going like nothing happened. No warning, no errors, in Enterprise Manager the State control of the file is VALID. I opened the control file, but it is still published (so it has not been automatically replaced by the good, which is not a good thing anyway).
Why is this happening? The system is unable to warn me if one of the control files is corrupt?
Thank you
Adrian

restore database backup cold no redo file
Hi all
I use oracle 10 g 2 Sun 10. I have a cold backup (control files and data files), any redo files.
I will restore the database from this backup? control to recreate... file is possible.

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.

2000 laptop 365DX: need to restore but have a restore partition point or recovery.
Hi guys. I have a laptop HP 2000-365DX with Windows 7 Home Premium. Its so crowded and I need to restore back to original settings. I had installed Ubuntu (partitioned) all the time and has been very stupid, because I deleted my partition recovery HP tools. Now, I searched here on HP.com to order a recovery disc and apparently I can't find one for my specific model. So what I have done is downloaded a file .iso Windows 7 Home Premium (with a good soul on these forums) and I need to download all the drivers for my laptop as well but HP is having some problems now so I can't download them (which is fine that I'm in no hurry). So, that's all as far as my knowledge goes. I have my Win7 disc and hopefully soon have my drivers disk. What I do not know how, it's clear my computer to start from zero Setup Win7 again then all my drivers. I read that DBAN (Darik Boot and Nuke) erases your hard drive clean, but that seems very extreme. Looks like I would use to wipe my drive hard if I had to sell my laptop or to erase the evidence, but if that's my solution I'm cool with that. So, really, I'm wandering what I should do now. And I really re - install my drivers as well? Any help would be greatly appreciated!
Hello
You can delete all existing partitions on the HARD disk during installation, as follows.
Start the installation.
When you get to the screen 'What type on installation', choose the custom (Advanced) option, and then click drive options (Advanced).
Here you can delete all existing partitions at a time by clicking on the partition to highlight it and then click Remove.
A when you're finished, you'll have just one entry named not 'allocated space' - just proceed with the installation.
Kind regards

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.

Restored control file has old data file path?
DB version: 11.2.0.2
On a new machine, we have successfully restored under the data files to the desired location.
After the restoration when I questioned v$ datafile it still shows data from the source server file path because the restored control file still has the old path to this topic.run { set newname for datafile 1 to '/data/oradata/clspdb/clspdb_system01.dbf' ; set newname for datafile 2 to '/data/oradata/clspdb/clspdb_sysaux01.dbf' ; set newname for datafile 3 to '/data/oradata/clspdb/clspdb_undotbs01.dbf' ; . . . . restore database; }
Now I have to issue ALTER DATABASE DATAFILE to RENAME... Since the SQL prompt before I run the RECOVER command. Right?Now I have to issue ALTER DATABASE DATAFILE to RENAME... Since the SQL prompt before I run the RECOVER command. Right?
No need. Include
SWITCH DATAFILE ALLin the execution block just after the RESTORE command. That is to say. It must precede the RECOVER command. This should update the control file with the new paths
It should look like
run { set newname for datafile 1 to '/data/oradata/clspdb/clspdb_system01.dbf' ; set newname for datafile 2 to '/data/oradata/clspdb/clspdb_sysaux01.dbf' ; set newname for datafile 3 to '/data/oradata/clspdb/clspdb_undotbs01.dbf' ; . . . . restore database; switch datafile all; recover database; } -
Test system update fails on ORA-01113: file 1 needs media recovery
I use Oracle 9.2.0.6 on HP - UX (B.11.11)
I'm refreshing to a test of production on the same server system.
The update fails on...
ALTER DATABASE OPEN RESETLOGS;
ORA-01113: file 1 needs media recovery

-Take prod tablespaces out of backup mode
-pass the prod (once for each newspaper group) log files
-copy files from archive prod to test
STARTUP NOMOUNT
Create control file from a copy of the prod trace file
(CREATE CONTROLFILE REUSE SET DATABASE 'ELLTEST' RESETLOGS ARCHIVELOG)
It works
RECOVER DATABASE USING BACKUP CONTROLFILE

ALTER DATABASE OPEN RESETLOGS;
ERROR on line 1:
ORA-01113: file 1 needs media recovery

I think I have I have all required log archiving prod?
Any advice?What you're trying to do is an incomplete recovery of the database. Since the redo logs are not used in your recovery you must explicitly specify the time to stop. If you do not process assumes a complete recovery and will require a request for reinstatement of online recovery log data that you do not.
You can use UNDO based recovery with
RECOVER DATABASE UNTIL CANCEL USING BACKUP CONTROL FILE;
then type CANCEL after the last active log has been applied.
Open with option RESETLOG database. It should work.
