Oracle 8.1.7.4 - restore controlfile

Hi,
I am wanting to know if you can use the following command to restore a controlfile, if you don't use an rman catalog with Oracle 8i (8.1.7.4).
restore controlfile from '<dir>/cf_rman.bus'
If you can't do this, then I am wanting to know alternative ways.
Appreciate any suggestions on this.
Many thanks

I dont know what rman 8.1.7.4 does or does not support. But you can go for user-managed recovery, as is the case with most of oracle 8.
cp /backup/control01.ctl /oradata/control01.ctl
Then recover using: recover database using backup controlfile.

Restore controlfile from tape backup without autobackup setting on

I am testing a scenraio of restoring control file if we loose all control files.
My RMAN settings for CONTROLFILE AUTOBACKUP is OFF. But, I have taken a backup of controlfile using 'BACKUP CURRENT CONTROL FILE' .
When I tried to restore control file. I am receiving following error:
RMAN> run {

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>';

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)';

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!!!

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

RMAN error when restoring controlfile from tape

Hi,
We have a Production database with instance name PROD.
We use Symantec Netbackup software to backup this database to tape library.
We want to test some recovery scenarios on a test server. So we want to restore the production backups from Tape to this test server.
We did the following:
Cloned the ORACLE Home to the Test Server.
Changed the db_name parameter to PROD and also set ORACLE_SID to PROD.
then we connected to RMAN and ran the following command to restore the control files:

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:

To answer this question I would first like you to tak a scissor , remove the CAPS LOCK from your keyboard, and I recommend you stop using uppercase and boldface.
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 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

Will be very much thankful to you...In an emergency situation, you can try using the SNAPSHOT CONTROLFILE.
Oracle is very clear on this point and says that this file should not be used for any purpose, but breaking this rule, we can have success and bring a consistent controlfile.
The snapshot control file is a copy of a database control file created in an operating system-specific location by RMAN. RMAN creates the snapshot control file so that it has a consistent version of a control file to use when either resynchronizing the recovery catalog or backing up the control file.
The Default Location of SNAPSHOT CONTROLFILE is $ORACLE_HOME/dbs/snapcf_<DB_NAME>.f
If we recently used RMAN most recent controlfile will be my SNAPSHOT CONTROLFILE.
See this example:
SQL> create pfile='/home/oracle/spfile.txt' from spfile;
SQL> !
oracle@aix:/home/oracle> cp /u01/app/oracle/product/11.2.0/dbhome_11203/dbs/snapcf_dbtst.f /home/oracle/control.ora
oracle@aix:/home/oracle> vi spfile.txt
"spfile.txt" 27 lines, 957 characters
*.control_files='/home/oracle/control.ora' ## Change this line
SQL> startup mount pfile ='/home/oracle/spfile.txt'

### We can open reseting log if you have all datafiles restored.
### Or you can use RMAN command to restore your database from Controlfile Catalog.
### Also you can generate a command to create a new controlfile

Restore solaris db on linux can't restore controlfile

Hi all. Hope someone can help with this.
I take my backups with this conf.
configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '/u02/backup/rman/<sid>/ctl_sp_bk_%F';
I do full backups at 3:00 am and archive log backups every hour.
I've copied my backups to the exact same locations on the new server.
rman
set dbid
connect target /
set controlfile autobackup format for device type disk to '/u02/backup/rman/<sid>/ctl_sp_bk_%F';
restore controlfile from autobackup;
no autobackup found or specified handle is not a valid copy or piece
I can rename the file to just %F and copy to <ORACLE_HOME>/dbs and still same error.
When I restored on a solaris box I was able to restore when I renamed the file to just %F and placed in the dbs folder but not on the linux box.
Any suggestions or something I've left off?
Thanks.

You are in luck, with 10g you can utilize
RMAN Cross-Platform Transportable Databases and Tablespaces to perform this operation.

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;

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.
Thanks

Restore controlfile from backup location

Hi All,
I have a RMAN backup and want to recover my data from backup. RMAN backup has taken by someone but during restore to another DB server I am confused at controlfile point. I can see two controlfile in RMAN backup. Do I need to add both controlfile in restore command or any one controlfile would be okay? Please suggest.
I run below command - rman > restore control file from '<backup location>';
Thanks...

I run below command - rman > restore control file from '<backup location>';In you log file one of backup set contains of data files another backup set contains Controlfile + SPFILE(optional)
Or else you can check from source database
RMAN> list backup of controlfile;
Note that backup piece according to date, and you can use that piece name to restore controlfile.
