RMAN backup on the database with data file with corrupted block
Hi friends,
I have a problem with a database of oracle 11g XE on windows server 2003, the database is in production, it is open, is operating normally.
The database has no backup configured before, so I put the database archiving mode and tried to backup using rman utility, but it show me some errors.
First of all, it showed me:
ORA-19501: error in reading file... SYSAUX. DBF
ORA-27070: async read/write failed
OSD-04016: error queuing an asynchronous i/o request.
And when I passed the dbv on the SYSAUX file utility. DBF showed the fatal error.
So, I switched CHKDSK utility on windows to repair the disc of the error. After that, run utility dbv and he passed and showed me the corrupt on SYSAUX blocks. DBF
Then, came to rman and ran:
RMAN > validate the logical database checking;
State of the file marked corrupt blocks examined empty blocks high YVERT
Finally I try to rerun rman and he shows me the error:
ORA-19566: exceeded the limit of 0 blocks corrupt file C:\ORACLEXE\APP\ORACLE\ORADATA\XE\SYSAUX. DBF
How can I do backup with rman? Maybe I can by pass the corrupt block?
I'll be grateful for any help you can provide.
=)
It would be better if you try to find the reason of corruption and try to recover the corrupt blocks. A block corrupted in the backup would really not must use. But if you're ready to take backup, you can ask RMAN to ignore corrupt blocks and move forward.
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:
SQL > startup ORACLE instance started.

SQL > shutdown immediate The database is closed. The database is dismounted. ORACLE instance stops.

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.
Every time you pass a cold backup database. We create a new controlfile with new locations of data/redologs etc.
And then we execute "create controlfile reuse...". noresetlogs...; "to create the controlfile.
After that, we will open the database as > > alter database open;
Now the question is:
We are able to open the database without clause "resetlogs.
Here, we create a new controlfile so SNA to controlfile will not be synchronized with the SCN of the datafile and redo the file.
Please let me know how the new controlfiles' SNA is synchronized with the data file and redofile and wea are able to open the database without resetlogs clause.
Oracle: 11.2.0.4
OS: Linux
If your cold backup also includes online redo logs, a RESETLOGS is not necessary.
The controlfile is created if it does not have a SNA, it reads the data file headers the YVERT database. For a cold backup, all the headers of data file are consistent. (This is also the reason why a RECOVERY is not required).
We check if our backups are valid or not. So it gave me a new server and backups/archives to a 2 TB database I need to restore/recovery. I followed steps below.
(1) copied the prod parameter file to test.
(2) make the necessary changes in the init file.
db_file_name_convert, etc..
(3) start db in nomount mode.
(4) restore the backup control file
Restore controlfile to ' / oraback/ARCH/prod/backup_controlfiles/c-250795000-20141030-01';
(5) mount the database.
(6) created under the rman script and executed.
Run {}
Catalogue start with ' / oraback/RMAN/test "noprompt.
Catalogue start with ' / oraback/ARCH/test "noprompt.

Questions-
-Restore completed successfully, but I found that few archives are missing.
-I pulled from database to recover until cancel using backup controlfile; There is a below error
ORA-01152: 1 no file has been restored from a sufficiently old backup
ORA-01110: data file 1: ' / u02/oradata/testsystem01.dbf'
-Then tried to restore the archive of available backup archive and few of archives have been restored.
i.e. of sequence between 759529 and 759552.
And then I pulled the database until cancel using backup controlfile recovery and I got errors below.
SQL > restore database using backup controlfile until cancel;
ORA-00279: change 144185396330 September at 26/10/2014 to 08:14:01
Thanks to those who answered previous questions about my attempts our 9i database recovering.
The details are that we had a Database 9i running on Windows XP. The computer has been damaged but we recovered the hard drive where the Oracle database. I also have a very recent RMAN backup. The steps I have taken in the recovery of the database are:
(1) install 9i (2) creation of instance with ORADIM (3) tried to restore SPFILE with RMAN, but he said that the backup did not contain the SPFILE (4) copied SPFILE old old oracle directory 4A) RESTORE CONTROLFILE FROM "path to old piece of backup", it seemed to work fine. (5) mounted on database (6) copied the last backup piece (and capture instant controlfile: sncf [sid] .ora) to the new database folder (7) tried to RESTORE the DATABASE, but failed to restore, after the first sale correctly all the data files to restore, with ORA-19505, it is looking for the second to the last backup (that may still be available to another source, I'm looking for it) (8) BACKUP of LIST done. It shows all the backup until the second to last, but not the most recent (9) CROSSCHECK BACKUP OF DATABASE, it shows that all backups are expired, does not show the newest one (10) has tried to RESTORE the DATABASE again, this time it is stopped (without the ORACLE error), saying: there is no backup of the six data files.
I may be able recover the backup piece that he needs. I suppose that if I move it into the database directory and that you raise OVERLAP that I would be able to RESTORE it (?). However, I'd rather widely to use the most recent backup, which is also in the database directory.
Any ideas on how to obtain RMAN to recognize this backup piece?
Thank you!

Once the RECOVERY is completed by RMAN, do not use RMAN to OPEN the database. JUDGMENT of RMAN.
Then use SQLPLUS / AS SYSDBA and MIGRATE FROM STARTUP ALTER DATABASE OPEN RESETLOGS
I want to restore a machine (RMAN) backup to another machine with a different instance name. I want to keep the target database instance name.
a machine has instance PROD, I take rman backup "PROD" A machine instance and to restore that backup to the machine B which has an instance 'UAT '. I want to restore the backup of "PROD" instance for instance 'UAT', the two are on a different node, please help me how can I achieve it.
Why do you think there could be a conflict?
In addition, the steps that I pointed out are rename restored PROD to UAT the last step.
When you use RMAN to RESTORE and RECOVER a database, the DBID and DB_NAME should be the same as it was when the backup was performed. The Instance_Name (ORACLE_SID) may be different. The DB_NAME can be changed after the RECOVERY is complete.
The DBNEWID Utility Oracle (program name 'nest' in $ORACLE_HOME/bin) should be used to change the DB_NAME of PROD to UAT on your UAT server, once the RESTORE is complete.
The only data in the System tablespace file is lost. The DB has crashed. We have the RMAN backup and the newspaper archive since the last backup of level 1. With RMAN, where should we go
a. restore, Recover Database or b. restore, recover any SYSTEM tablespace?
Your database must be mounted State.
RMAN > run {} allocate channels ch1 disc type; system restore of tablespace; recover the system tablespace. SQL 'ALTER DATABASE OPEN; }
Hello! We create consistent backup RMAN in our CARS (ASM with FRA) environment. Safeguard measures looks like:
alter system set cluster_database=false scope=spfile sid='HAC4';
srvctl stop database -d HAC
Then we begin the RMAN backup script as (database is closed to the ground before):
run {
startup mount;
allocate channel t1 type disk format '/u01/rman_backup/HAC/cold_backup/HAC_%U';
allocate channel t2 type disk format '/u01/rman_backup/HAC/cold_backup/HAC_%U';
SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u01/rman_backup/HAC/cold_backup/HAC_%F_ctl';
backup as copy database include current controlfile;
}
After backup, we realize:
alter system set cluster_database=true scope=spfile sid='HAC4';
shutdown immediate;
and later
srvctl start database -d HAC
This backup backup files are placed on the area of local disk accessed by noeud4, where HAC4 SID is on. We transfer the backup files to tape on an hourly basis...
Now, we want to test this backup. Scenario: Because we have consistent backup, we think we can restore her (from files on this disc) and him ALONE! Our problem is that while restoration is the use of the DSO files, so we're not sure is our backup.
So, how to prevent the RMAN restore/recovery process of using any ASM file - just to use our consistent backup data?
Please a few example script for this...
Our config: Oracle 10gR2.0.4 PS3 (NCPS, ASM database), Linux Rhel IA64 5.3 on 'raw devices' (no raw disks)

Hello
What I realized is that you want to test the image copy backup you took earlier and test this to restore the database, as it is.
Now, if I see your script, it shows that you have restored control file and then you tried to recover the database.
But when you make the copy of the image of the database, and you want to restore, then you have to try to restore the database first. I don't see any "restore order" in your script.
Hi all I need to store the rman backup in linux like system date of the file. I created the folder *#mkdir /bkp/ $(date +%Y%m%d) *. and I've tried this, RMAN > backup database format ='/ bkp/$(date +%Y%m%d)/db_%d';) does not, how to solve this problem.
My data files is ASM Diskgroup and as well as file system. When I try to replicate the database with RMAN, data files gets duplicated.
It creates files of data in directory '+ data/dup10g/OMF' and it creates data files with the same name as my DB goal in the framework ' + data / < database name > '.
I don't know why this is happening. When I try to delete the data file under ' + data / < database name > ' using the rm command, it removes all datafiies in ' + data / < database name > ' and he delete the folder of dup10g also.
I do not know what is going on here that you could try to remove the parameter db_file_name_convert the duplicate must then create files OMF managed under the location specified in db_create_file_dest
Unforunately Undo Tablespace data files are deleted from the server. Database is running in no archivelog Mode and I have not any any type of backup.
Last week, I did only read only work with the database. So not really concern how I is coward.
The biggest concern is how to open the database with existing data files?
Kind regards Sumit

If no active transaction or data required by one of the session to restore, then it will be difficult to recover these transactions and your database data will be in a State of incoherence. As you only read only activity you can safely recover the database.
Comment just undo tablespace and undomanagement parameters init.ora file and restart the database.
Once the database is in place create undo tablespace and assigning like default undo tablespace tablesapce.
After you create the database, it is automatically saved with the listener. I am not registered the database with listener then how it registers itself automatically with the listener. How a registry database that is automatically saved.
