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 want to restore control file from backup set,just as the flowing command,where location does the control file be restored to? how can i specify the location when restore control file?
restore controlfile from '/u01/rman_backup/mybak/df_768589733_7_1.bak';
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?
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 want to ask if I restore a control file from backup of say day2 and I recover till day1 using RMAN script, then what will be the state of my database? I mean day2 control file may be having SCN-Day2, and I am instructing RMAN to recover till past point in time that is SCN-Day1.
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';

taking the backup of a control file, as i am taking online backup, archive mode.
At first i have executed the statement
sql> alter database backup control file to trace;
then i have removed the control files and enterd some data in a table and committed it.As my oracle is not shutting down, so i shut aborted it. Now after saving the last file from the udump as obkp.sql i am unable to edit this file and use.
how to edit and use this file, so that i can startup my database normally.
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?
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.
using target database control file instead of recovery catalog

This is exactly the same message if you do "RESTORE DATABASE FROM TAG='NONEXISTENTDUMMYTAGXXXX'" Why can the data files not be found even if they are listed in the backup?

To what i understand one can restore a missing control file if you have multiplex it. so I did this :
-- while it is being down, i use OS command to copy a good copy of the control file to the missing controlfile location + name.

I have installed oracle 11.2 on virtual machine and made two copy of this vm i.e vm1 and vm2...i have taken fullbackup with rman on vm1 and autobackup of control file.Now i want to restore this backup on vm2, for this i have configured channel and other setting. run following command
catalog start with '\server3database_backup manC-3507808503-20130531-00';
"C-3507808503-20130531-00" is the name of control file autobackup.
RESTORE CONTROLFILE ;
it gives me error RMAN-06496: must use the TO clause when the database is mounted or open...then i use following command
RESTORE CONTROLFILE to 'C:oracleAdministratororadataslate';
then it gives me error RMAN-06024: no backup or copy of the control file found to restore...how to restore control file to vm2
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:
select completion_time, marked_corrupt, media_corrupt, logically_corrupt 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!
We're running 10.2.0.4 Database on AIX with no catalog Database.We keep all the backup info in controlfiles only.When we do that backup, we're able to successfully back it up (including archivelogs). But I'm unable to find any records in the controlfiles.

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?
Starting Control File and SPFILE Autobackup at 19-JUN-12 piece handle=C:ORACLEPRODUCT10.2.0DATABASEC-3843121877-20120619-00 comment=NONE Finished Control File and SPFILE Autobackup at 19-JUN-12
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?
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'C:ORACLEPRODUCT10.2.0DATABASESNCFPLDG.ORA'; # default
We are doing RMAN Duplicate set until time to refresh daily our test database for our developers and it taking long time to finish. We noticed on the restore log that RMAN was using a day old old backup pieces to refresh the test database and don't immediately use the latest backup pieces instead.
For additional details here's the rman duplicate command we are using which we run daily(mon-sat) at 4am once daily full backup on production completed.
RMAN Duplicate commands: run { set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 04:00:00', 'Mon DD YYYY HH24:MI:SS')"; allocate auxiliary channel ch1 type disk; duplicate target database to testdb; } exit
Is there a way on how to let RMAN use the latest backup pieces instead?
We are using Oracle 10g R2 in Windows Server 2003. I'm trying to restore a database in a new server, using RMAN backups.
Our external consultant configured RMAN scripts for full and incremental backups but never tested them . Since he just doesn't show up, I'm forced to tested them, restoring the whole database in a new server.
My instance is named MTDPROD, and I will create all from scratch.
At current server, RMAN files are generated in: //192.168.1.149/g$/XXXSRV4-ArcLogs/MTDPROD/RMAN
At new server, I run all these commands:
C:>oradim -new -sid MTDPROD -intpwd mtdprod Instance created -- I created the relevant folder hierarchy under <ORACLE_BASE> directory -- Then, I created the relevant directories for Oracle Database, as follows: --a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>
[code]....
By instance, I see a lot of this kind of files:
- FULL_MTDPROD_20110529_386_1.BAK - INCR_MTDPROD_20110621_480_7.BAK And only see these two files: - C-2169285856-20110527-03 - C-2169285856-20110527-04
It seems that this C-2169285856-.... files only were on 27/05/2011 and then no more. However, the FULL_... and INCR_.. files are generated every day. The FULL is generated at the end of each month and INCR is generated every day.
This is the backfull.sql:
run { allocate channel c1 type disk maxpiecesize=4G; CROSSCHECK archivelog all; backup incremental level 0 format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANFULL_
[code]....
This is the backincr.sql:
run { allocate channel c1 type disk maxpiecesize=4G; CROSSCHECK archivelog all; backup incremental level 1 cumulative format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANINCR_ %d_%T_%s_%p.bak'
We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.
I am attempting to use an rman backup form our live server to restore live data over an existing dev database with a different name. I cant use the duplicate command as the versions of oracle are different (10.2.0.4 EE on live, 10.2.0.5 SE on dev) So I copied the backup sets including an autobackup control file onto the dev server. I set the ORACLE_SID to the DEV version (SUN43DEV) and startup nomount and restore controlfile from the backup location. This works and restored the live controlfile. However, I then wanted to mount the database and catalog the backupsets before making a note of the last archivelog etc and restoring the backup with set newname options. But when I try to mount the database I am told that the database has a different name (SUN43 is not SUN43DEV). I read somewhere that I need to set the ORACLE_SID to the live value (SUN43) and restore as that, then use nid TO RESET THE DBID and DATABASE NAME. However, my tnsnames on DEV has no entry for the live database, and we do not have any service defined through ORADIM for the live instance on the dev server. Should I be creating an entry in DEV tnsnames that actually looks at the LIVE server? or do I need to create a service and tns entry etc for SUN43 on my DEV server pointing at the DEV server I have not seen any mention in instructions of creating a service or adding the entry to tnsnames, or indeed adding an entry to the listener for the original live sid. I am worried that if I actually point to the live server then the restore would be attempted on the live server not dev even though I am running it from Dev.
Also, do I need to drop the existing database on DEV before I restore or will RMAN just restore over the top of it?
Finally, if I try to add an entry to the LISTENER.ORA for the new sid, when I stop and start the listener, or reload, the entry is not recognised. I also noticed that the existing SUN43DEV entry is not in there either, yet I can still use that SID - I am assuming that is because the listener is not being used and the sid is recognised from the existence of the service in windows services instead?
I am trying to create my database on a new server using rman incremental hot backups.
I have already restored and recovered my level 0 database on new server, but i am not able to restore/recover the level 1 backup on the new server. I have transported level 1 backup irom the old server to the new one. Do i need to recover lvl 1 bkp only or restore it also.
I need to restore entire database(sp+control+datafile) to new host.I have started the instance with nomount( and it has created a dummy parameter file).Now, I need to fire the command to restore spfile.
RUN { ALLOCATE CHANNEL c1 DEVICE TYPE sbt PARMS='...'; RESTORE SPFILE TO PFILE '?/oradata/test/inittrgta.ora' FROM AUTOBACKUP; SHUTDOWN ABORT; }
My questions:-
1.How will RMAN find the location of backupset(Since there is controlfile for neither target or catalog database)?
2.How does RMAN reache the backupset in case of a)tape b)disk?
