In DR site. i have to clone the database from pshysical standby database and clone db will be normal db not standby. Is it possible to do rman duplicate from active dataguard? will it support the duplicate database from active database or i have to take the rman backup of standby database and duplicate from backup piece.
View 2 Replies,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
We are planning to create physical standby database for 4-node RAC primary to a 4-node RAC standby using Active database duplicate with ASM and OMF
1. while using active database duplicate, do we need to set cluster_database=FALSE in spfile clause and create standby,next change it back to TRUE at standby. Or we don't need to touch it. And also do we need to include instance_number parameter
2. We are using OMF, can we use log_file_name_convert parameter in spfile clause of duplicate. Documentation says log_file_name_convert cannot be used if standby is going to have OMF. Because we have 5 groups for each thread, which are on 5 different disk groups. When standby is created all the logs are created in only one disk group pointed by db_create_online_file_dest_1.
3. To enable force logging at primary do we need to shutdown the database?

I am new to Oracle, like to get clarified on below;
1. From where can we run the RMAN Clone script?
Source DB : PRDDB HOST: PRDHOST
Destination DB: DUPDB HOST: DEVHOST
Are there any constraints on running the RMAN Script from the Source DB Host - PRDHOST?
If I am running it from PRDHOST, do I have to have the initdupdb.ora available on PRDHOST?
What are advantages and disadvantages on running the script on Source & Destination Host?
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.

I have setup 11g Dataguard - physical standby. Everything seems to be fine. I have also tested switchover and failover using DG broker which seems to work fine.All, I would like to know is abt ORA-01109 during switchover..
My config - RACprim- RACstby
Primary - TEST_prim (instances - TEST1, TEST2)
Standby - TEST_stby (instances - TEST1, TEST2)
DGMGRL> SWITCHOVER TO TEST_stby;
Performing switchover NOW, please wait...
New primary database "TEST_stby" is opening...
Operation requires shutdown of instance "TEST1" on database "TEST_prim"
Shutting down instance "TEST1"...
ORA-01109: database not open
[code].....
This ORA error occurs when it tries to shut down primary. When primary is in open state, why its saying that database not open. Operation requires shutdown of instance "TEST1" on database "TEST_prim"..Shutting down instance "TEST1"..
I have failed to duplicate target db for standby from active db using spfile with the following errors:

[Code].....
The script has successfully created on standby db all controlfiles and also has copied 2 data files DATA01.DBF and DATA02.DBF into the correct location. Then the errors above kicked in and stopped the rman dup process.
1) The Primary Database is UP. The Physical Stand By Database is DOWN. The Current Archive Log Sequence is 99 in Primary.
We have to apply Archive Log from 51 to 99 to the Standby Database. But Unfortunately, there is no backup of those Archivelogs and the ArchiveLogs from 51 to 98 have got deleted at Primary end.
Now how will you apply these Archive Logs from Primary Database to Physical Standby Database?
Note : The Physical StandBy Database is DOWN.

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 ?
We are running 11.2.0.3.2.
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?
I am trying to duplicate an Database and create an Physical Standby through following command

We are using oracle as database in our application. For high availability we have a cluster of multiple nodes and the data is replicated using oracle streams. All the nodes in the cluster are active. We do not have any concept of stand-by.
Now we are planning to use oracle RMAN for backup and recovery. RMAN user's guide doesn't recommend any strategies for such deployments. It mainly focuses on primary/stand-by deployments.
I have 2 databases. Primary ( DB1 ) and Standby ( STBY1 ). My standby database went kaput, and i have as a result deleted the standby database in order to re-create it from a full primary backup.
Oracle 10g R2 on Server 2003.
I have followed several guides, and at this time i have done the following:
- Configured standby re-do logs on primary
- backed up current controlfile for standby
- backed up database plus archivelog
- configured the tnsnames
[code].........
The problem is here. I connect to RMAN from standby
rman nocatalog
connect target sys/password@ DB1
connect auxiliary /
run{
set until scn xxx;
duplicate target database for standby dorecover;
}
I receive an error message saying that it cannot find the file location of the backups that its trying to find. I see in the error that it tries to look locally for
E:FLASH_RECOVERY_AREA DB1 BACKUPSET2013_02_12), however the actual location is (E:FLASH_RECOVERY_AREA STBY1 BACKUPSET2013_02_12)
I have read that the locations need to be the same, however the instance names are different, and i thought i changed the pfile to accommodate that. My assumption is that i have made an error in the pfile. However i cannot see any issues there. Some things that i have changed in the pfile for standby:
*.db_file_name_convert='DB1','STBY1'
*.db_name='DB1'
*.db_recovery_file_dest='E:FLASH_RECOVERY_AREA'
*.db_unique_name='STBY1'
[code]........
Can i setup physical standby without RMAN? I want to create a fresh single physical standby without RMAN .. If i copy all files in another system and take the controlfile from primary as alter database create controlfile for standby ... and fill all the gaps with archives.. Should it work ? i am on 10G Rhel 4 linux.. and both machines would have same config

I have configured a physical standby database.
I have set the physical standby database to open read mode for a short while.
according to [URL] in order to set db in for from open read-only to applying redo data
Quote:
To change the standby database from being open for read-only access to performing Redo Apply:
Terminate all active user sessions on the standby database. Restart Redo Apply. To start Redo Apply, issue the following statement:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> DISCONNECT FROM SESSION;
To enable real-time apply, include the USING CURRENT LOGFILE clause:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> USING CURRENT LOGFILE;
this is what happen
SYS@ngdr> alter database recover managed standby database disconnect session;
alter database recover managed standby database disconnect session
*
ERROR at line 1:
ORA-00274: illegal recovery option SESSION
SYS@ngdr> alter database recover managed standby database using current logfile;
okay since I encountered the illegal recovery options session, I decided to use alter database recover managed standby database using current logfile; now the session seems to be hanging forever.
I've got a physical standby database and I'm now licensed for Active DataGuard. I would like to automate the ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION command to be executed right after the STARTUP command so that whenever the database is started by our DBSTART script, it activates READ ONLY W/APPLY immediately after start without manual intervention. This is probably simple, but I figured I'd ask before starting to pore through documentation.....!

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?
I have recently patched my catalog home to 9208 from 9204; the target database is still on 9204 but now I cannot connect to the catalog database.

Performing backups on the physical standby via RMAN. We need to restore our test database, and right now it is equivalent to the production. The DUPLICATE command seemed the best bet. We have controlfile and SPFile both on Auto-backup, and the RMAN on a six day retention with weekly 0 level backups and nightly level 1 cumulative backups.
However, when I run the DUPLICATE it chokes being unable to find a current controlfile nor one in backup, even though we have six days worth of supposedly good (validated) backups. We are not using a catalog, rather the DB controlfile.
The solution to this error is reopen the database and try again. however, the physical standby cannot be opened. It is the standby. What if we move the last backup to the primary database, "register" it there, and try this DUPLICATE?
I have seen nothing on this in my searches, and the Oracle documentation does not address this, though it recommends backup from the Physical Standby.
RMAN-05513 is the error code.
I want to duplicate a prod database in to a dev db.I am using catalog database to connect to target and auxiliary datbase.I copied all backupsets to the local disk on Dev env in the correct path.For RMAN duplicate ,does the backuppeices need to be present on PROD filesystem as well or just DEV filesystem or both.
