Recovery Manager (RMAN) :: Control File Restoration
Mar 7, 2013
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?

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?
We need to test mean time to restore from rman backup. So can we restore the data file to new location on the same server without effecting the Database.?
On production environment i am running Oracle 10g (10.2.0.4) on windows server 2003. and take full compress backup through rman .
I have create a new machine from scratch OS (windows 2003 server) Database Oracle 10g R2 (10.2.0.4) same architecture as live,
Can i standup a instance with the backup i have taken from my live database. And if yes .......how can i ......means i want to take backup from live and restore it on new created machine
I took database backup without "change the controlfile configuration autobackup on".. and unfortunately i deleted my controlfile. Then I tried to restore my controlfile but it gives error,now how can i restore controlfile is there any other way to restore controlfile with aautobackup..
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.

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 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 ?
O.S Version HP-UX B.11.31 U ia64 Oracle DB Version 11.2.0.3.0 Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production Scenario :
Using RMAN Active cloning to duplicate a RAC database from Production to Development environment.
Problem:
At the end of the cloning the below errors are reported; RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: ===========================================================

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?
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';

So /dd_oraback is a Data Domain mount. Not sure if that makes any difference or not.
How one should know whether RMAN is using target database control file or using separate catalog database. Also what one should do if he dont have catalog users credentials.
I got Saturday rman level 0 backup and sunday, monday, tuesday & Wednesday level 1 backup.got some issue and i have to restore the backup with minimum data loss. path for restoration of the backup. We can restore 1st level 0 backup, but how to apply others level 1 backup on that.
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 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 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?

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.
I have RMAN backup on TAPE. I need to restore control file for particular date on another host. How do I restore control file to new host for particular date?
EXAMPLE:
4949 Full 11.25M SBT_TAPE 00:01:09 06-AUG-12 BP Key: 4949 Status: AVAILABLE Compressed: NO Tag: TAG20120806T223455 Handle: COTSPRD_c-4007601229-20120806-00 Media: 030256 SPFILE Included: Modification time: 28-MAR-12 SPFILE db_unique_name: COTSPRD Control File Included: Ckp SCN: 237324864 Ckp time: 06-AUG-12
Can I rrun command like : RESTORE CONTROLFILE FROM TAG 'TAG20120806T223455;
I need to clone from tape to another server for particular date.
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
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.
