Restore Backup Without Control File
Sep 11, 2011
I have a problem with my control file [URL].........
What I did, I have a duplicate of the database with the invalid control file, let's call it DUMDB. I am using my control file and no recovery-catalog-db.
I recreated the control file. Now everything is working fine, new backups can be taken, restores can be made. I just need to restore a backup tagged with "LASTDEV". The control file for this backup is the invalid one. So I need a restore WITHOUT restoring the control file.
I did:
CODERMAN> catalog backuppiece '/u03/flash_recovery_area/DUMDB/backupset/o1_mf_nnndf_LASTDEV_75fmkllw_.bkp';
cataloged backup piece
backup piece handle=/u03/flash_recovery_area/DUMDB/backupset/o1_mf_nnndf_LASTDEV_75fmkllw_.bkp RECID=1 STAMP=761604017
CODERMAN> list backup;
using target database control file instead of recovery catalog

I take hot backup of database at 10:00 am.After taking the hot backup 50 archived logs are created.Out of 50 i have backed up first 25 of them and at 5:00pm i lose complete database including control,data and the last 25 archived log files that were not backed up.So I am using latest hot backup to recover
I restore the control file backup and datafile backup taken during ho tbackup(10 am) and i issue the command
.......startup mount
>>>>>>>Recover database until cancel
!!!!!!! Apply the available 25 archive logs
then i give "cancel" since I dont have the next redo log .Now in which mode will the database open(Reset logs or no reset logs)

I did a hot back up like this :
--check that it is in archivelog mode
SQL> archive log list
-- the data files that will need to be backup by OS command
SQL> select sum(bytes) from dba_data_files;
SQL> select name from v$datafile;
-- note archivelog sequence before starting the hot backup (need to back the archivelog generated during the backup)
SQL> select thread#, max (sequence#) from v$log group by thread# order by thread#;
-- begin the backup
SQL> alter database begin backup;
-- use OS command to copy the datafiles
-- remember to end the backup mode
SQL> alter database end backup;
-- archive the current online redo log files
SQL> alter system archive log current;
-- REMEBER to note the MAXIMM online-redo sequence number
select thread#, max (sequence#)from v$log group by thread# order by thread#;
-- backup the control files
SQL> alter database backup controlfile to '/oradump/hbackup/O11R2/controlbk.ctl' reuse;
-- backup any archive-redo logd generated during the backup
-- select from the v$archived_log mode
-- anything thing that appear under this view is safe to backup as long you don't backup the current archive log file that is being written to.simulated a scenario, if 1 of my multiplex control is damage due to media failure ( i just delete it, seem like i got to shutdown first before i can delete it, using window bases oracle, not too sure linux allow you to delete the control file like this)
To what i understand one can restore a missing control file if you have multiplex it. so I did this :
ORACLE instance shut down.
SQL> startup
ORACLE instance started.
-- while it is being down, i use OS command to copy a good copy of the control file to the missing controlfile location + name.
-- startup

You have tried to move one or more copies of control file at the different location when Oracle database was up and running.
You have tried to restore from database backup but your backup has not taken properly. It may taken when database is up and running.
Your database or system got corrupt/damaged during updation was in process.

I've got a legacy SAP system with oracle 8i on Tru64. No changes at all are made but for legal reasons we have to keep it up and running.
we currently do a full backup monthly by shutting down oracle and doing a backup of all the files to tape and that takes around 12 hours.
If I stop doing the full backup and I only backup the control file and the archived redo log files every month and I had to restore the full database years from now, would I be able to restore the database using the last full monthly backup and use the latest control file and archived redo log files?

The controlfiles were corrupted due to some issue. So, I had to restore the recent backed up control file and then restore the database.
The weird thing which I have noticed is that. I tried backing up Yesterday's Control file. So, I would say that the backup pieces it should pick should be from yesterday. however, the backup pieces are getting restored from last week's backup.

I am having a issue, we are trying to restore our db from control files using Symantec Backup exec, but job fails giving me error go to table spaces select all table spaces and unchecked roll forward.
i am unable to find way to uncheck the table spaces. Here is the complete description.
Cause
The system catalog tablespace "syscatspace" contains all of the system catalog information for the tables. Syscatspace needs to be rolled forward first, and then the other tablespaces must be rolled forward.
Solution
Workaround:
When the restore operation is run from a tablespace level backup, perform the rollforward for the syscatspace tablespace first and then for other tablespaces.
Execute the rollforward operation as a DBA operation. The sequence of the recovery process should be as follows:
1. Select all tablespaces, uncheck the rollforward option and run the restore job.
2. Run the rollforward operation as a DBA initiated operation:
rollforward syscatspace to point in time / end of logs. e.g. db2 => rollforward database UEXIT to end of logs and complete Tablespace (SYSCATSPACE) online
3. Perform rollforward of all other tablespaces.
e.g. db2 => rollforward database UEXIT to end of logs and complete tablespace (SYSTOO LSPACE,USERSPACE1) online
Refer to IBM DB2 documentation for more information on DBA-initiated operations.

I had a database on an old P4 running but the motherboard got fried. I was able to recover all the data files (.ctl and *.dbf) plus the redo logs (.log). There is no export or backup taken - I have old ones, but I need to recover the latest which only existed in the data files.
I now have Oracle installed on a new P5 machine and was wondering if it is possible to use these data files in the new database? If so, how do I go by restoring the data files?
Both the P4 and P5 where running Red Hat Linux.

Suppose I take a multi stream backup, say 3 streams.
So if a control file is backed up in say backup set 1, so is the whole control file is backed up in one backup piece or it may span multiple pieces?
A backup set may have multiple backup pieces.

This is what I run
run {
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/dd_oraback/tkprod/%F';
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 22 DAYS;
sql 'alter system archive log current';
[code]...
So /dd_oraback is a Data Domain mount. Not sure if that makes any difference or not.

I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.
I have completed the following steps in the restore process.
1. Creating a pfile from spfile
2. Changing the the location of cdump, udump, bdump and the control files ( there are three )
3. Then creating a spfile from this pfile
I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.
After mounting the database in RMAN, tried to run the following.
RMAN> run
2> {
3> allocate channel c1 device type disk
4> ;
5> @/home/oracle/rman_scripts/newloc.rman
6> SET NEWNAME FOR DATAFILE 1 TO '/u02/oradata/dorian/system01.dbf';
7> SET NEWNAME FOR DATAFILE 2 TO '/u02/oradata/dorian/undotbs01.dbf';
8> SET NEWNAME FOR DATAFILE 3 TO '/u02/oradata/dorian/sysaux01.dbf';
9> SET NEWNAME FOR DATAFILE 4 TO '/u02/oradata/dorian/users01.dbf';
[code]....
I am getting the following error message.

I've recently moved jobs and am doing a lot of the normal things getting familiar with my new company's databases.I was checking through our production backup logs and came across something that looks a little funny. From the last two days backups, I see:

from v$backup_datafile
where controlfile_type = 'B'
order by completion_time desc

The 01:40 record will come from our nightly command:
BACKUP INCREMENTAL LEVEL=0 FILESPERSET=20 FORMAT 'full_%d_%t_%s_%p'
DATABASE INCLUDE CURRENT CONTROLFILE
The 11AM records will come from the command:
BACKUP INCREMENTAL LEVEL=0 FORMAT 'ctl_%t_%s_%p' CURRENT CONTROLFILE;
(I know backups shouldn't still be running at 11am and we don't need level 0 backups every night, that's a seperate issue I'll be addressing! ) I see there's been a similar entry here in v$backup_datafile for all backups that there's records for. The database is up and running just fine. There are no unusual errors being reported by the database in OEM or the alert log.I tried looking at both our control files (yes, should have 3 - something else I've listed to change!) with dbverify which showed no issues - though I'm not sure if this is designed to work with control files.
If so, how could I confirm whether it's an issue with a specific controlfile (I'm assuming it's not an issue with the backup to tape itself, as it's reporting the same corruption every day)?I'd obviously like to diagnose this now while the db is up and running, rather than at 4am some morning during a crash and finding out my backup control files are no good!

I've pasted some of the results of an RMAN backup that I ran. It says that it's backing up both the Control File and the SPFILE, but it appears that only one file is being created. Is this correct? How does this work? Are both files combined into the C-3843121877-20120619-00 file?

Also, regarding the below configuration of RMAN - I can change this directory to whatever I want, correct? In other words, is it just the directory where I am putting the backup?

We are trying to restore a database to a cold backup DBID.However while our datafiles were backuped up for 6 months retention we found out subsequent delete obsolete command wiped out the Control file related to this backup piece..Now what is left with this backup piece is just datafiles..
Can we still recover the database with a subsequent controlfile autobackup for the same DBID.?
