Recovery Manager (RMAN) :: How To Make Only 1 File Backup
Jan 22, 2013
During the last week, we faced many network issues that prevent our RMAN files to be copied completely. Backup team offer a temporary solution that we have to generate only one backup file to be transferred from source to destination (tape).
I am making incremental backups via RMAN, the backups are staying at disk. And the infrastructure team will copy this files backups to tape. And they want delete the files that will staying in disk via RMAN. Until now it's ok.
But and if I need of backups that stay on tape, it's possible make a recovery of deleted files by rman.
I was handed a folder that consists of all the files (Datafiles, controlfiles,spfiles, backupsets etc) for a database. The SID is Oracle.
So now I have two options:
1. Attach the Datafiles
2. Restoring the Database with the Backupsets.
Option 1:I tried with working with the control files but didnt get anywhere because I did not understand how to attach the datafiles (I tried modifying the control file, to no avail).
I tried replacing the spfiles and pfile then copying the datafiles (replacing the existing ones)...but I could not create the control file as well...
Option 2:I do not know how to make RMAN see the backupsets of the Old database; despite they are in the same location as those of the new database.
While connecting to target database from stand database. I am getting below error.

Backup-Based Duplication Without a Target and a Recovery Catalog Connection?
I have seen in many RMAN backup scripts that a manual log switching is performed in first line of the script? What is it purpose, just to write changes needed to reconstruct the DML/DDL statements to online redo logfiles and start the archiving process if db is running in archive log mode?
I am using Oracle 11.2.0.3 RAC (2 nodes) + ASM on AIX 7.1
I am backing up my Oracle database through RMAN to ASM disk groups..I have a requirement to backup also to an OS file systems. So what I did that I mounted an NFS across the 2 nodes of my RAC database.I am running backup from node 2 only.My issue now is that I am facing a real performance issue when backing up to NFS.My question is there any way to take an RMAN backup to local file system on node 2? or in other way what are the options to take RMAN backups to an OS file system?
I tried to copy from ASM to OS file system but i was advised to backup to file system using the format command.what should i do in such case? since I am facing performance issue to backup to NFS.
I took backup of Datafiles , archivelog files and controlfile through RMAN. Now, i want 3 backup file will created as a output of RMAN operation. It would be :
1 backupfile for all the datafiles 1 backupfile for all the archivelog files 1 backupfile for controlfile.
It have to be regardlessly whatevr my DB size is. It it possible to do so. How i can can write rman script to accomplish the task.
Can't start the Database and can't backup What is happening now. My database connection is not stable so can't do the backup.I spent two days trying unsuccessfully.
check the following print screen : [test@localhost ~]$ xhost +access control disabled, clients can connect from any host[test@localhost ~]$ [test@localhost ~]$ [test@localhost ~]$ su - rootPassword: [root@localhost ~]# [root@localhost ~]# [root@localhost ~]# su - oracle[oracle@localhost ~]$ [oracle@localhost ~]$ export ORACLE_SID=db11gr2[oracle@localhost ~]$ [oracle@localhost ~]$ echo $ORACLE_HOME/u01/app/oracle/product/11.2.0/db_1[oracle@localhost ~]$
7 of days ago Full backup has been taken to disk due to issues with tape devices.3 days ago tape devices have been fixed and we switched to CommVault managed tape backups. CommVault calls RMAN with following command:
These backups done successfully.Then archivelog backup taken similar way.But when I issue RESTORE DATABASE PREVIEW SUMMARY; RMAN starts with Full backup set, though newer Incremental Level 0 ones are available.Why it does not use these newer ones?
I have an issue with restoring a RMAN backup that i have with me to a new database instance. What i have with me are: 1. Backup of SPFile.
(O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_.BKP)2. Backup of Control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_.BKP)3. Full database backup (O1_MF_NNSNF_FULLPROD_BU_92DVGW9H_.BKP)
I have received these files from a customer environment and I need to restore these to a new database instance in a local machine. I have given a attempt as follows (in Oracle 10g): 1, Created a new database instance (Test75) using Oracle Database Configuration Assistant2. SET ORACLE_SID = Test753. Connected to this instance using RMAN4. Tried to restore the SPFILE from the received BKP file.I am getting errors and cannot proceed. I am not sure whether I am executing the correct steps.
One of database, while taking backup using RMAN, it failed with the following error:
RMAN-03009: failure of backup command on DISK4 channel at 11/28/2012 09:47:29 ORA-19566: exceeded limit of 0 corrupt blocks for file <faile_name>
I used DBV to identify the number of blocks corrupted.
I referred the Metalink iD 457422.1 & 336133.1. But it did not work since the corrupted blocks have got object in it.
I could able to find the object as well. it is one of the table in the datafile.
I used 'ALTER TABLE ... MOVE..' command to see if that works. But again getting the same error while taking the backup and corrupted blocks still exists.
am trying to run rman backup plus archivelog TO tape disk my rman configuration settings are as seen below
RMAN configuration parameters are: CONFIGURE RETENTION POLICY TO REDUNDANCY 2; CONFIGURE BACKUP OPTIMIZATION ON; CONFIGURE DEFAULT DEVICE TYPE TO DISK; CONFIGURE CONTROLFILE AUTOBACKUP ON; [code].....
get the following error when i do this, RMAN-03009: failure of backup command on C3 channel at 01/03/2013 11:33:45 ORA-00600: internal error code, arguments: [ksfdfetch1], [], [], [], [], [], [],
,I am new to Oracle database administration i am working on a 24*7 tool .the tool will work as a non stop.this is a standalone tool.there wont be any one who will be taking care of the database.I need to design a backup statergyNeed to take backups on timly basis.Since the database can't be go offline cold backup's can not be useenhot backup needs to implemented.what are steps needs to do for hot backup.Is there are some pre defined scripts to run the backup.
We have Oracle 11g on Windows and Daily full Netbackup on Tape @3:00 Am and on disk @3:00 Pm .When we try to restore DB with following command it restore control file from Disk and Not from Tape .
RMAN> RUN{ 2> allocate channel t1 type 'sbt_tape' parms='SBT_LIBRARY=C:WINDOWSsystem32orasbt.dll'; SEND 'NB_ORA_POLICY=ORACLE_DBMS_KTPH12_PROD_BTS_Daily, NB_ORA_SERV=b-nimhp1sys101, NB_ORA_CLIENT= b-btshp1dbs213';4> restore until time "TO_DATE('17-02-2013 03:00:00','dd-mm-yyyy hh24:mi:ss')" controlfile to 'G:oradataTLPRDdcontrol01.ctl' from autobackup; 5> }
Why it is not restring from Tape and Restoring from DISK?
I am tryign to run a split onlike full backup from the os useign the sap command which is linked to rman..Command that i am useing is ...

The backup goes thru but i get this erro on the end...

I am trying to setup incremental backup on my windows OS based server using RMAN command in batch file. When I use batch file in OS scheduler it is working fine, when I am calling same batch file from my LOCAL desktop PC it throws errors as below.

So /dd_oraback is a Data Domain mount. Not sure if that makes any difference or not.
I'm using database 11g & restore backup from another location.

Could we skip the backup of the above missing files using RMAN -> backup database skip inaccessible;On further research, this would compromise tablespace SYSAUX recoverability...Questions:
1) What caused the above missing files to get created? 2) What is recommended: Recover the datafiles?
I have oracle 11.2.0.3.0 in Windows 2008 server R2 64 bit version. I have installed database ASMDB with ASM ... Now i have another one machine , I want to clone my database in that machine with Non ASM file system .. Can any one tell me step by step document to do it ?
Can i keep the database name as ASMDB in another Machine ?

How to prevent the error of RMAN-06054: media recovery requesting unknown archived log for thread with sequence and starting SCN of while performing the RMAN Active Cloning? I do NOT want to use UNTIL clause.
In my catalog for the "source" database (rman target db), I have the backupsets for a full database backup ended at Feb. 7, 03:43:37. These are online backups. So, there are archived redo logs being generated while it runs and the following archived redo logs finished at Feb. 7, 04:00:24.
We duplicate databases all the time. So, this is not a new concept for us. The one thing that has changed is that we now back up to disk (using the flashback recovery area) and then later on, initiate a backup to tape. Prior to this go-live, we did all of our backups directly to tape. The catalog does not seem confused. It knows it needs to go to tape because it's beyond the retention for disk backups. The only problem is that it is going to the backup prior to the backupset I want, only for a couple of files.
In the past, when all went directly to tape, we would do a set until time 'Feb. 7, 03:43:37' and it would automatically restore the backupset that finished then and apply archived redo logs as necessary to make a consistent copy. Now, if I use the same model, it's going to a backup set from the prior date for 3 particular files. If I change the time to when the archived redo logs ended their backup, 04:00, it still goes back to the day before, but only for 2 files.
I can list a backup of each specific file and see that the file is in the backupset for which I expect RMAN to pull. How can I figure out a date/time to go back to if not using the method of reviewing the catalog entries and timestamps?
