Recovery Manager (RMAN) :: Possible To Make Recovery Of Deleted Files
Jan 6, 2013
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.
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 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.
I am using RMAN with a recovery catalog option on a separate Database. My question is
When we use catalog does RMAN keep the information in Control file of the Target Database as well or only in recovery catalog? I am asking this in case We lost the database which contains the recovery catalog what to do?
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 problem on using "delete obsolete" in RMAN.
First, let describe my backup configuration.
1. Full backup every Monday (17-Oct, 10-Oct, 3-Oct, 26-Sep) 2. Incremental backup for other days 3. Enable autobackup of control file 4. Backup archive log every day 5. RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS 6. Execute "Delete obsolete" every day 7. control file is used instead of catalog
The results observed: 1. Backup of control files older than 30 days will be deleted 2. Backup of archive log files older than 30 days will be deleted. 3. Backup of datafiles older than ~14 days but before 30 days are also DELETED.
In my example, the backup of datafiles created at 26-Sep is deleted at 16-Oct.
I tried "restore database validate until time "sysdate-22"" at 17-Oct. And RMAN reported "datafile xx will be created automatically during restore operation". It seems that RMAN failed to do restoration up to 22 days ago. The retention policy I set seems not effective on datafile backups.
I checked view v$backup_set and the "Keep" is "No" and "Keep until" is empty.
The only thing I can think of, is the settings of "CONTROL_FILE_RECORD_KEEP_TIME". It is marked "7" in the Oracle, which is less than the retention. But I suppose this only causes the backup not deleted, but NOT be deleted earlier.
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.
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?
11.2.0.3 win 2003. have direct aim to restore database from inc0+inc1 backup + recover up to latest archives made after inc1.
Steps have to be done:
1. SQLPLUS> startup nomount from pfile='......'; 2. RMAN> restore controlfile from ... 3. SQLPLUS > alter database mount; 4. RMAN> run {

Questions:
1. Why it ignoring "set new name" and db_file_name_convert?? 2. Why no backup or copy of datafile 1,2,3,4 found to restore, it can seee it clearly through all its commands?
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.
We have a nightly rman backup that was complete and clean.The backup contains a Data File, Control File and a backup Archive Log file.The database server crashed with all the subsequent archive logs lost.
We are trying to recover from the three backup files.We are bumping into the backup piece missing as all the archive logs are done. how to restore with the exising backup files. the lost archive logs are probably salvageable.
Can I register a database say MYDB in datacenter1 with two different catalogs i.e., I have one rman catalog a datacenter1 location and another rman catalog in datacenter2 location. So, can I register MYDB to rman catalogs at datacenter1 and datacenter2. If, so how can we keep rman catalogs at datacenter1 and datacenter2 in sync. For MYDB rman backups I just want to use local rman catalog which is datacenter1. But I just want to keep a redundant copy of the rman catalog.
,I have a test environment with Primary DB Server, Physical Standby and Logical Standby.The Logical Standby DB (cur_log_stdb) is backed up every evening by RMAN and I have a question:If I recover my Logical Standby DB from backup and switch replication to new Logical Standby DB (new_log_stdb) it will work or not?My steps e.g.:1. Make a new server for my new_log_stdb and repair structure of catalogs;2. Repair listener.ora and tnsnames.ora files from cur_log_stdb to new_log_stdb;3.
Restore DB with RMAN from backup to new_log_stdb;4. On cur_log_stdb execute "alter database stop logical standby apply";5. Change a DNS name from cur_log_stdb to new_log_stdb;6. On new_log_stdb execute "alter database start logical standby apply immediate";I'm not sure that archivelogs will apply to the new_log_stdb for period since rman backup was created. Configuration:Oracle Linux 6.4Oracle Database 11.2.0.3Primary and Physical with Data Guard
Oracle 10gR2 on 64-bit RHEL.Backup Strategy:There will be a level-0 backup of the database every Sunday and level-1 every weekday.Archivelogs will be backed up up every 30 minutes.
Q: How can I delete ALL the archivelog backups that were taken that day (every 30 minutes) right after successful completion of level-0 or level-1 backup?
I want to delete them because they may not be of any use after the level-0 or level-1 backup (am I right)?
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?

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 $ORACLE_HOME/u01/app/oracle/product/11.2.0/db_1[oracle@localhost ~]$
I have Oracle 10gR2 database on a windows server, I have scheduled rman backup for this database from Solaris server
set echo onrun { crosscheck archivelog all; backup check logical database plus archivelog; delete noprompt obsolete device type DISK; } exit;
It is deleting the obsolete backup pieces but it is not deleting old archive logs (obsolete archive logs) and it is not even showing old archives as obsolete when I check thru report obsolete
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.
