I am very new to oracle and I wanted to know if I have a backup rman complete level 0 (with archiving log) that I took today (09/02/2012-13:00 pm cst)...
and now the question is... is it still possible or oracle is able to make me back off let say 2 days back with just my backup I took 2 days? .. .but remember, I don't have that level 0 backup that I took today... lets say I am on version 11.2.0.1
My understanding of rman, I can only go back until 09/02/2012-13:00 CST? or can I go back let said 07/02/2012 13:00 CST?
In your case only RMAN cannot go back back data. You would need to have the old backups who when needed and/or have flasback enabled database (http://docs.oracle.com/cd/E11882_01/backup.112/e10642/flashdb.htm#BRADV180).
Technically it is a good idea to back up the server backup-database (database of RMAN with catalogue) with RMAN or is it better to take a cold backup of your RMAN database with the catalog of all your databases that are stored on the catalog rman one database?
My thoughts are that it is better to take a cold backup of the RMAN catalog database or take an export of the database of RMAN catalog. Please share your point of view. Thank you
Hello
The easiest would be to create two databases of catalogue and half of you, the databases put in #1 and the other half in #2. To use the catalogue #1 as a repository for the backup of the catalog #2 and vv.
Another option would be to turn on controlfile autobackup (always a good idea) and use this file in case you need to restore with rman catalog
(1) order catalog added a copy of the data file information, archived redo log or copy of control in the repository files. (2) add metadata to a copy of the data file managed by users, copy of control files, archived log or backup piece to the RMAN Repository.
After using the 'CATALOGUE' to add metadata to managed backup in the catalog of recovery and after having made "RESYNC CATALOG", I still don't see my backup listed in the output of
RMAN > list backup

backup of the list won't show you the results.your not done backup with rman directly taken by data copy.so file

above cmd will show that you have desired results check it out.
How do RESTORE RMAN of the CARS to single Instance on another node with NAME DB different...
My production database name was "GENPROD"... my test server database has been 'MIGUAT '.
When I do the restoration, I get the following error:
RMAN-00571: =========================================================== RMAN-00569: = ERROR MESSAGE STACK FOLLOWS =. RMAN-00571: =========================================================== RMAN-03002: failure of the restore command at 06/08/2012 13:22:11 RMAN-06026: some targets not found - abandonment of restoration RMAN-06023: no backup or copy of the file 4 found to restore RMAN-06023: no backup or copy of datafile 3 found to restore RMAN-06023: no backup or copy of datafile 2 found to restore RMAN-06023: no backup or copy of datafile 1 found to restore
Please help me with this...

Hello
You can take a look at http://taliphakanozturken.wordpress.com/2012/07/20/how-to-restore-10g-rman-backup-to-11g/
You will need to change the name of db only after the database was opened after the upgrade and other steps.
Hello How to restore the tablespaces only 4 not all areas of storage in one database to the new database of cloned all cloning with RMAN?
I don't think it's possible to restore only 4 storage space for the database 'auxiliary '. Instead, you can use the "SKIP TABLESPACE" cloning while clause.
You can exclude the tablespaces that you don't want the database duplicate with the SKIP TABLESPACE clause. You can exclude any tablespace except the SYSTEM tablespace or tablespaces containing rollback or undo segments.
Refer to this http://docs.oracle.com/cd/B14117_01/server.101/b10770/rcmsynta28.htm
Perhaps this impact that all face you when creating physical standby DB. I'm trying to create a physical standby database Using RMAN double order a server
(pri machine) machine on standby.
Here are the steps I followed to create the above:
Step 1:-activate forced logging
SQL > ALTER DATABASE FORCE LOGGING;
Step 2:-set up a standby Redo Log
SQL > ALTER DATABASE ADD STANDBY LOGFILE GROUP 10
2 > ('/ oracle/dbs/log1c.rdo','/oracle/dbs/log2c.rdo') SIZE 500 M;
Step 3:-set the parameters of primary database initialization
SQL > create pfile='?/dbs/pfileorcl.ora' of spfile;
Edit the pfile to add the sleep settings, shown here:
Step 6:-backup of database and copy it to standby mode
This backup script must be run on primary and copied to sleep on the same mount point, run these scripts with RMAN, all files in /rman_backup need to be copied in /rman_backup on the standby server.
$rman target.
RMAN > run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
backup of database format ' / rman_backup/%U';
ARCHIVELOG backup all the format ' / rman_backup %U ';
backup current controlfile to Eve format ' / rman_backup/%U';
}
Step 7:-availability of measures database
Installation of Oracle software
This should be the same version and patch group with exactly same ORACLE_HOME mount point.
Commissioning of the listener
Create and start a listener on the database of sleep by using NetCA, or create listener.ora in $ORACLE_HOME/network/admin
A password file must be created on the primary and copied to the standby site. The sys password must be the same on both sites. Copy orapworcl in $ORACLE_HOME/dbs and rename the file in orapworcldr
Step 11:-create for Oracle mount points
Mount point must be created on the standby server with the same convention used in primary education, which includes the location for controlfiles, redo logs, data files, destination of the newspaper Archives and alert logs.
$ mkdir Pei/u01/app/oracle/oradata/orcl /.
$ mkdir Pei/u01/app/oracle/flash_recovery_area /.
$ mkdir Pei/u01/app/oracle/admin/orcl/adump
$ mkdir Pei/u01/app/oracle/admin/orcl/bdump
$ mkdir Pei/u01/app/oracle/admin/orcl/cdump
$ mkdir Pei/u01/app/oracle/admin/orcl/udump
Step 12:-use RMAN to restore the backup and standby configuration
Connecting to RMAN and run the following command to create the database pending, this must be performed on the standby server after the backup copy and the tnsnames parameter.
All output data base Oracle can restore backup sets and copies created by any prior release of Oracle Database.
However, in order to open a database, the data must match the version of the Oracle binaries. If you restore and recover a previous version of the database, you will need to update database permission to open it.
RMAN cannot upgrade and migrate a database, but you can use the wizard for DBUA do. I suggest that you only consider this document showing your upgrade options:
Unfortunately, there is no way to upgrade direct 11.1.0.6 12.1 and you must upgrade the database to 11.1.0.7 first before restoring it. Other options, see the link above.
We backup data base of sbt with rman and nmda library (networker).
We want to copy the disk sbt backupset. Is this possible?
Kind regards
William
I remember that this is not possible. It was perhaps possible to redraw the rman backup and restore concepts, but there is probably no real business applications. Remember that a band or an sbt (series tape backup) is a streaming device. You can read from tape or write about a band, but you can't read and write in the same band at the same time. What syntax would you choose to perform an rman backup from tape to disk or tape to tape? Rman backup you can specify a peripheral channel of exit and entry for the use of the restore command. As far as I know, the rman backup source is the database control file and it reads no Ribbon.
DB version: 11.2.0.4.0, not the RAC environment, single instances
That's happened? My My db catalog rman session did not survive? Why the error happened at 09:00 (and not 17:00)? Why the session called the catalog rman during switching of the data files?
Can someone explain it to me?
Thank you!
Hello
The connection of the RMAN catalog remains inactive during the backup/restore process, once rman completes the task and try to activate the connection it gets error.
What is expected as you said the rebooted server. If this happens because of the expiration time, we went with the parameter net expire_time to maintain the connection.
Hello. I use the server of Oracle 11 GR 1 material with operating system Oracle Linux 5.10 database.
I understand how to back up the database instance in SQL Server with Windows. But do not really understand how to back up the database instance in Oracle on Linux. I did it cold and hot backup for the database HRCS90 instance, but both receive the same error message.
Cold backup is below:

While the instance of database HRCS90 is starting, I do hot backup by using the same commands and get the same error message with above cold backup.
My question is:
Can any folk tell me specific steps (order by order) to back up a single instance of the database in Oracle with RMAN?
Thank you.
Yes, you can restore and recover the backup, but not at the moment. You will only be able to restore and recover at the time of your backup.
For example.
If you take backup (mount point with no mode of journal archive) at 06:00 and your grave database crashes at 21:00, you will be able to restore and recover until 06:00. You will find all the changes made to the database between 06:00 and 21:00.
If you want your database to recover until 9 PM or until a point in time, then you must put your database in log mode archive, and then save the archives.
ENV: Oracle 10 g 2 64 bit, RHEL 5.8 64 bit on ASM, Database size = ~ 1.3 to
Backup RMAN of PROD will FRA and then backed up to tape. I have limited access to the PROD because it is maintained by 3rd party.
My client is planning to move this database on their own datacenter (from the 3rd party data center). For test purposes, I asked DBA of 3rd party to provide us with an export of drawings required data pump. Export takes about 8 hours, and the import takes the same time to the new location. To copy the files exported to new locations takes another few hours (over the network). The total size of the dump file is around 500 GB. Thus, a whole cycle of Export-Import-copy takes about ~ 20 + Hrs.
I want to try another option to reduce the time required for the updating of the database of PROD and which is "use RMAN backup of PROD ' and restore it on the data center server. RMAN full backup takes ~ 4hrs PROD and the restoration should be at the same time (new server has better and faster HW, storage with a SSD). I found this thread very useful on the Oracle Forms on this topic:
This thread contains very good example for a restoration of database on the file system.
I have a bit of confusion because my database uses ASM. The default location of the backups in PROD is FRA (on ASM == > db_recovery_file_dest = + FRA ). If I understand correctly, the RMAN backup must be in the same place where he was on the PROD Server - i.e. the diskgroup FRA.
If I get a copy of the part 3 RMAN backup, how would I copy on FRA?
OR can / should I just change the init parameter "db_recovery_file_dest" on the new server to point to the file system directory where the backup (say "/ ora_backup") and RMAN will pick up and restore the database?
Please advise!
Best regards
You can restore the backup files to any location, then you must configure the channel using the "CONFIGURE CHANNEL device type disk format 'new location ';
