Backup & Recovery :: RAC Database Duplication Using RMAN?
Jan 27, 2011
I have done many duplication before in sinlge instance databases using a backup tool and rman catalog. At the moment i was trying to do a RAC database duplication and facing some issues. For this i was doing a testing on my 1-node RAC. Primary and duplicated database is on the same Host and oracle version is 10.2.0.3. I perfomed following steps:
1.Created a DUPL database using DBCA.
2.Created a pfile using spfile.
3.Dropped all the datafiles, controlfiles and redo log files.
4.Started the database in nomount using pfile.
5.Disable cluster related parameters in pfile.
6.Took a full backup of the MAIN database with archivelog on disk.
6.Duplicate the database and it is done successfully.
7.Shutdown the instance and enabled cluster parameters.
8.Start instance using SRVCTL fails with error CRS-0215: Could not start resource 'ora.DUPL.DUPL1.inst'
But if start the instance using sqlplus it comes up nicely. There is not much information in alert log files.

I like to duplicate the database DATABASEA to DATABASEB and need to be run in same server. I tried to bounce the listener & databaseb instance multiple times but no lucky.
Step 1 : The instance DATABASEB is in Nomount stage
Step 2 :

I'm trying to set up active database duplication between 2 Oracle 11g servers.
Both servers were set up with identical configurations (same directory structures, file systems, SIDs, and sys passwords.) Both oracle instances were created at the time of software installation.
Here is how things are configured:
- Version: Ora11gR2
- Oracle service name: orcl
- File system: ASM
- OS: Windows Server 2008
I've done some research and found several sources giving instructions on how to set up active database duplication (including a blog engry by rajabaskar on this site), but each site seems to have different details.
So, here's what I have so far:
- Set up entries in each TNSNames file... each has an entry 'src' and 'dst' (for source and destination)
- A new listener has been added on the source machine
- on the destination machine, run the 'oradm' to create a new SID. However, is this really necessary? Since the service names are already the same
- I'm also supposed to create a password file on the destination machine using orapwd. Again, is this necessary, if I'm using the same passwords on both machines?
Am I on the right track? Should I have created an actual database on the destination machine or should I have started with just the software installed?

I have 2 identical databases set up as follows:
- Version: Oracle 11gR2 (64 bit)
- OS: Windows Server 2008
- File System: ASM (with GRID Infrastructure)
Both instances are virtually identical... Same directory structures, same SYS passwords. The only thing that differs is the instance name (one is ABC, the other is XYZ).
Now, both databases are up and running, both have users on them, and both can accept remote connections. What I want to do is set up a very simple 'copy' system so that everything can be extracted (via RMAN) from the first database, and replace the database on the second. (Then, the user can log into XYZ with the same usernames/passwords they used on ABC.)
Here's what I'm doing so far:
On the 'source' database (ABC) I run RMAN as follows:
rman target / nocatalog
configure controlfile autobackup format for device type disk to 'C:\temp\CF_%F';
configure channel device type disk format 'C:\temp\bkp_%U';
run {backup database; backup archivelog all; }
Now, I'm not completely sure of what to do on the 'destination' database. I've seen multiple web pages with instructions that require the creation of a new instance using 'oradim' and the creation of a new password with 'orapwd'. However, is that necessary if I have the same sys password on both databases, and I want to use the same XYZ instance name on the destination machine?
Would it work if I used 'delete database' on the destination, and then used the RMAN 'Duplicate database to XYZ backup location 'C:\temp\'? Or does it HAVE to be a new instance created with oradim?
And if I DO have to use oradim to create a new instance, will the data be accessible through XYZ too?

We are running a 5Tb database backup which takes really a long time to backup and impacts the performance in general during the backup. We got a DataGaurd database in place which we want to utilize to run the RMAN backup on to avoid performance impacts and just use DG database for backup and DR purposes. My Question is if we run the backups on DataGaurd Database, How would a RMAN DG database backup would clear the archive logs from Primary production and from DataGaurd Database during the backup process?

I have issue with regards to duplication of an active (prod) database to a test database. This is my sql run by RMAN:
SPOOL MSGLOG to '/proddb/u01/app/dupe.log';
CONNECT target sys/oracle;
CONNECT auxiliary sys/oracle@MWTEST;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
RUN {
duplicate target database to MWTEST from active database;
}
CONFIGURE DEFAULT DEVICE TYPE TO SBT_TAPE;
It stops however in the middle and wouldn't continue. There is still huge space for the test database (3x the current size of prod database).

I would like to duplicate to the different server Oracle Database with RMAN. I've configured flash recovery area for Oracle Database.
My questions are:
Source Server ( target ) : ORACLE_SID : DB11G
AUXILIARY Server (duplicate ): ORACLE_SID : CLONE
1- if backup files (autobackup and backup set)/ Archived Logs are in a different path on the source host (not default FRA Path) then how can I use the DUPLICATE command? BTW, only the flashback logs are in the default location (/u01/app/oracle/fra/flashback). Path: /u01/app/oracle/oradata/DB11G/autobackup and /u01/app/oracle/oradata/DB11G/backupset.
2 - Do I have to add *_CONVERT parameters for different SID as shown below? e.g. : DB_FILE_NAME_CONVERT , LOG_FILE_NAME_CONVERT.
DB11G.__java_pool_size=4194304
DB11G.__large_pool_size=4194304
DB11G.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment
DB11G.__pga_aggregate_target=155189248

Applications R12 (12.1.3)
Operating system : Redhat linux 5.5
I would like to know how to create recovery catalog database to acheive rman backups as control file will not keep backup info longer. This is for our production database what are the requirements before doing so and what happens to configure retension policy to recovery window.
Initially plan of taking backup to disk and later moving backups to tape device

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 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.

I have a RUN file within a script to duplicate a database. As part of this RUN file I also run the command configure controlfile autobackup off; as part of this RUN file. However, this command has turned off backup of the control file on the AUXILLARY database (i.e. production) as well as the TARGET database (test). Is this supposed to happen?
My run file is:
rman TARGET sys/XXXX@${DB}-SOURCE AUXILIARY /
RUN {
allocate AUXILIARY channel a1 type disk;
allocate AUXILIARY channel a2 type disk;
allocate AUXILIARY channel a3 type disk;
allocate AUXILIARY channel a4 type disk;

We are trying to restore a database on the different server using RAM incremental level 0 and 1 backups. We have weekly Incremental level 0 backups along with incremental backups on daily basis. During recovery of Incremental level 0 backup, RMAN is expecting/looking for Incremental Level 0 backup of prior week as well. Is this the usual process for RMAN to look for prior level 0 backup though we need to restore from the current level 0 backup and roll forward by a week with subsequent Level 1 backup.?
We intend to restore from the Level 0 of 1/16 and roll forward with daily incrementals till 1/22. RMAN is expecting level 0 backupsets from 1/9 backup as well and keep failing since those backups are not available. quick inputs since we are in middle of recovery and trying to resolve if this is even doable.

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.
