How to restore controlfile ?

Hi,
I have a database. its has only one controlfile (multiplexing is not done).
But I have a proper backup of all...
All of sudden controlfile got corrupted.
Now I need to restore controlfile from backup. But I dont remember my DBid.
Can someone help how to proceed now?
Thanks & Regards,
Suresh S.

please find the DBID from log files and restore the controlfile from backup.
this may help you http://download-west.oracle.com/docs/cd/B19306_01/backup.102/b14192/recov004.htm#CFABADJC
also take it as a lesson and do multiplexing of controlfiles and immediately take full backup of database

FOR EXPERTS!! How to restore controlfile from tape using TSM??

Hi ,
I have a backup of my database (controlfiles, datafiles and archives) on tapes (TSM).
I'm doing some tests and i delete all my controlfiles.
Now i'm trying to restore the control file using the following:
RMAN>set DBID=1489198124;
RMAN>run{
allocate channel t1 device type sbt_tape parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_capdb15p.opt)';
restore controlfile from autobackup;

RMAN-03002: failure of restore command at 05/10/2007 16:25:30
RMAN-06172: no autobackup found or specified handle is not a valid copy or piece
The autobackup is OFF now (i will put this ON later and become a production enviroment).
How can i get the controlfile backup from tape. I have this backup on tape made by RMAN using TIVOLI STORAGE MANAGER.
Tks,
Paulo.

This is the command:
run {
allocate channel t1 device type sbt_tape parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_capdb15p.opt)';
backup current controlfile;
This is my backups!!!
RMAN> list backup of controlfile;

How to restoring controlfile when autobackup was not enabled from TAPE?

Database was dropped an year back and we need to restore the database
1)controlfile autobackup was not enabled
2)backups are in tape
3)no catalog db used
4)DBID is known.
we can request to load tapes that are holding backups from 1 week prior of db drop date
we can not use "restore controlfile from autobackup" as autobackup was not enabled. So how can we restore the controlfile?

1)catalog those backupsets
2)check the backup summary for controlfiles & datafiles, SPFILE(optional)
3) if exist then you can restore using DBID or catalog start with commands.

Personally I'd never use RMAN to restore a control file. Takes less time to job copy an existing one.

How to restore (not duplicate) DB from RAC ASM to non ASM

Hello everybody,
i am trying to recover db from RAC+ASM to non ASM no RAC node. I am running Oracle 10g (10.2.0.4) on Win2003 Server. I have functional backup from my prod system.
Here are my steps:
*1. On prod server i make backup running this script in RMAN*
configure channel device type 'SBT_TAPE' parms'SBT_LIBRARY=oracle.disksbt,ENV=(BACKUP_DIR=e:\backup)';
RUN {
backup device type SBT_TAPE database tag zal20081129;
SQL 'alter system archive log current';
backup device type SBT_TAPE archivelog ALL tag zal20081129;
*2. I prepared clon instance on another server (The same Oracle version) and start it to nomount mode.*
*3. I copied the backup from prod server to clon server to exactly the same path. (e:\backup)*
*4. I connect to RMAN on my new node and I use the DBID parameter and I restore controlfile.*
rman
connect target /
set DBID 3079749916
startup nomount
run {
allocate CHANNEL CTAPE DEVICE TYPE 'SBT_TAPE' PARMS'SBT_LIBRARY=oracle.disksbt,ENV=(BACKUP_DIR=f:\backup)';
allocate channel CDISK DEVICE TYPE DISK;
restore controlfile from 'f:\backup\78k91lrn_1_1';
alter database mount;
*5.Then I check the backup, crosscheck etc.*

So obviouslly database wants to open online logs in the path like ASM. Which is wrong. What should I do to tell database to open it according to init.ora parameters
*.db_create_file_dest='e:\oradata\agost'
*.db_create_online_log_dest_1='e:\oradata\agost'
Any suggestions???
Thanks

Hi,
thanks for you quick answer. But I do restore to the local file system, even if the log says:
restoring datafile 00001 to +DATA/agost/datafile/system.272.668509367
restoring datafile 00002 to +DATA/agost/datafile/undotbs1.273.668509387 .....
all the datafiles are correctly restored. I think oracle uses the parameter db_create_file_dest and creates the files there.
I tried also the script with SET NEW NAME:
run {

How to Restore Control file to New Server

I want to test my backup by restoring the full backup of my production database on a separate test server.
I have taken following action for restore to test server:
•     Copy full backup to Test Server on same folder where it was in Production Server.
•     Copy parameter file to Test Server. (Edit control file location on it)
•     Connect Rman
•     Set DB with new DBID
•     Startup Nomount (from new parameter file)
RUN
ALLOCATE CHANNEL c1 TYPE DISK;
RESTORE CONTROLFILE FROM AUTOBACKUP;
ALTER DATABASE MOUNT;
Then we found following error:

How to extract controlfile from backup set?

Hi
If I use this "INCLUDE CURRENT CONTROLFILE" in backup command direct to tape and no catalog, How to extract controlfile from backup set from tape?
Thanks,
Taohiko
Edited by: taohiko on Sep 17, 2009 7:54 AM

yes
list backup of controlfile
will show you where controlfile backup piece reside with backup piece name
after then

RMAN-06563: control file or SPFILE must be restored using FROM AUTOBACKUP
My question is, How can I restore control file from tape backup without CONTROLFILE AUTOBACKUP setting ON.
It sounds like, There is no way we can restore control file from tape backup if you've not set the CONTROLFILE AUTOBACKUP is ON.
Please advice

When all controlfiles are lost and a recovery catalog is NOT used, RMAN has no information , where to find the controlfile backup. It's not enough to specify the channel, such a channel could hold many different backups from many different databases. You have tell , which database and which backupset. Modify your run block:
SET DBID <DBID of the database,for which you want to restore the controlfile>;
RESTORE CONTROLFILE FROM <name_of_backupiece_which_contains_the_controlfile backup>';

Restore controlfile from leagato tape backup

I am using legato tool to perform rman tape backup.
I use the following script on legato to get the controlfile backup.
"backup current controlfile format '%d_%s_%p.ctrl'; "
If I lost the controlfile how do i restore controlfile from the tape. Assume that the DB in nomount stage.

Hi,
backing up autobackup controlfiles to legato is possible. All you have to do is to configure autobackup accordingly. By default autobackup controlfiles will get written to disk.
However i strongly recommend to use a rman backup catalog. This will save you a lot of time consuming trouble if you need to restore your database.
The rman catalog database itself does not need any license and is rather small (5 GB on disk, 512 MB memory).
Restoring the control file will be something like this:
set controlfile autobackup format for device type sbt to '%F';
restore controlfile from autobackup;

You can restore control file by specifying the path explicitly.
-- In the auxillary server
Make sure you have the CONTROL_FILES parameter in the pfile. The control files will be restored to this path
*.control_files='+LMNPROD_DG01/lmnprod/lmnprod_control01.ctl','+LMNPROD_DG01/lmnprod/lmnprod_control02.ctl','+LMNPROD_DG01/lmnprod/lmnprod_control03.ctl'Create spfile from pfile. Then
SQL> conn / as sysdba
Connected to an idle instance.
SQL> startup nomount
SQL> show parameter spfileStep5. Restore Control file
The below command will create all the 3 control files mentioned in CONTROL_FILES parameter in the spfile.
$ rman target /
restore controlfile from '/path_where_bkp_piece_is_stored/RMAN_CURRENT_CONTROL_BACKUP_0mnbvhlq_1_1.bak';After restoring the control file and mounting the DB , you can use CATALOG command to catalog backup pieces

For Datafiles and ArchiveLogs :
SET UNTIL works because RMAN can query the Controlfile (that is already present) {OR the Catalog, if available} to determine the Database Incaranation and identify all the BackupSets, BackupPieces and SCNs for datafiles.
For Controlfiles :
SET UNTIL needs to be able to query a source or determine a default location. If a Catalog is available, it can query the catalog. In the absence of the catalog, it can only determine the expected location to restore from on the basis of the AUTOBACKUP location and FORMAT.
When you have AutoBackup to Disk, using an FRA and have the AUTOBACKUP FORMAT set correctly you will notice that the controlfile backups go to a directory that has the date as part of the directory name. RMAN can "query" the backups it finds in each of the folders in the autobackup location and determine the correct piece to restore from. This is predicated on the FORMAT being the expected format. That is why the example also shows how you set the FORMAT before you do the restore -- to "tell" RMAN what format to expect. (Remember that it has no repository -- controlfile or catalog -- to query so it doesn't know the backup piece names, unless they follow the expected location and format !)
All of this works well on disk. On tape, it has to actually send it's requests to the Medial Management Layer -- it is the Media Management Layer that maintains the catalog of tapes and files on tapes. (Remember that RMAN still doesn't have a repository that it can query !).
Going back to my earlier comment that SET UNTIL is used for Datafiles and Archivelogs : Because it is much easier for RMAN to query a known repository for all the information it needs.

When to restore controlfile, rman is complaining database not mounted?

to restore controlfile, shouldn`t the database be in NOMOUNT status?
if yes, then why rman is complaining ORA-01507?
where I went wrong? Please advise.

it doesn`t. I tried long before this one.
the dilemma i am facing is that I need to recover to the time which was included in incarnation 2.
And to be able to reset database to incarnation 2, i need to startup MOUNT the database.
And once you startup mount the database RESTORE CONTROLFILE won`t work any more.
below is the standard procedure, documented on 10gR2 doc, but still, i am getting errors:

Backup set is over 7 days -- DB status is NOMOUNT -- RESTORE CONTROLFILE

I'm trying to do a restore of a control file using RMAN.
After doing a STARTUP NOMOUNT of the database, I try:
SET DBID = [whatever]
RESTORE CONTROLFILE FROM AUTOBACKUP;
The error I get is:
channel ORA_DISK_1: no AUTOBACKUP in 7 days found
And that's true. The backup set I'm trying to restore from is over 7 days old.
I tried
RESTORE CONTROLFILE FROM AUTOBACKUP UNTIL TIME "TO_DATE('12/17/08 18:00:00', 'MM/DD/YY HH24:MI:SS')"
and I get the same error.
All the examples I've seen using UNTIL TIME seem to assume that the database status is MOUNT not NOMOUNT, which is needed if you don't have a control file in the first place.
How do I get around this problem?
=== Al

Al,
Set your env variable oracle_sid = whatever_sid
then from command line
c:> rman target /
or
$> rman target /
And use one of the following to list your backups
RMAN> LIST BACKUP;
RMAN> LIST BACKUP OF DATABASE;
RMAN> LIST BACKUP SUMMARY;
RMAN> LIST INCARNATION;
RMAN> LIST BACKUP BY FILE;
RMAN> LIST COPY OF DATABASE ARCHIVELOG ALL;

That is definitely shouting and should be avoided.sorry....
Obviously when you need to recover a catalog database you need to do so in
nocatalog mode
So you need to use
rman nocatalog target /
and leave out the catalog part.acctually i have two incarnation ..i lost current incarnation datafiles and backup..
so that i want to restore controlfile and move to previous incarnation..

How to restore the control fie? without having RMAN catalog.

Hi ,
can anyone help me out here.???
How can i restore the control file.if i dont have the RMAN catalog.
Please provide me steps that'll be helpful. I am frsher in oracle DBA
Please mail me: [email protected]
Regards
Vikas Singh

Hi Vikas,
You can restore the control if you have the full backup of your database in some location.
Lets assume you have the full backup piecs in loc "/u02/backup/..bkp"
steps:
shut abort;
startup nomount;
catalog start with "/u02/backup/..bkp"
restore spfile from '/u02/backup/..bkp";
restore controlfile from "/u02/backup/..bkp"
shut immediate;
startup mount;
alter database open;
Once the db is up with controlfile immediately take the full database backup of your database.
Let me know having issue after following this.
