Duplicate from standby database to create a test database?

Hello!
Would it be possible to use backup-based duplication FROM a physical standby database to create another database to be used for testing? If I performed RMAN backup of the standby database, moved the backup to another test server, and then ran duplicate?
Anyone know if this would be possible? If possible, would the new test database's controlfile be "standby" or "primary".
(version 11.2.0.2)
thanks..

Yes it works ! I've tried that recently on 10g so I think on 11g will not be a problem.
You can do it with or without duplicate. If you want to use duplicate, you don't need to copy the backup. Actually, on 11g you don't need no backup at all, since now you have 'from active database' option for duplicate command !
Also, duplicate will rebuild the controlfile so it will not be "standby" or "primary" ...

Restore production from standby database

Hi,
I would like to make a standby database for my production database.
But, I have a basic question to restore my production database from standby database. There is a method to make it ?
If I lost all files from production database, how to restore from my standby datase (which become in this case my new production database) ?
thanks in advance for your help.
gnom92.

* I make a copy datafiles from my new production database (old standby database) on old production (where crash)
* With my old production database, I make a standby database on new production database (old standby)
* I can close the new production database and open the new standby database in read / write mode, and this is my production database.
* After what I recreate my standby database (old standby,newproduction), or can I return in recover standby mode ?
thank you very much for your patience.

ORA-01017 when RMAN duplicate from active database

Create dev database from standby database

Hi folks,
I need to create a dev database by using RMAN's method of cloning. But, since it is business hours and the production database is being used at a very high rate, I cannot carryout the cloning by connecting the primary database as it may cause performance slowness.
The time allotted for the activity is also very short. We have a standby database created for the primary database. So, my question is it possible for me to create the dev database using the standby database ?
Database version is 11.1.0.6 and I can go ahead with the active database feature.

Yes, you can clone from the standby database. Follow the below steps.
1. Check if your standby database is in sync with the primary database.
2. Cancel the MRP on the standby database.
alter database recover managed standby database cancel;3. connect to standby as target database and dev database as auxiliary
rman target sys/<pwd>@<standby-alias> auxiliary sys/pwd@<dev-alias>4. Your standby database would be in mount stage and dev in nomount stage.
5. Run the duplicate command
rman>duplicate target database to 'dev' nofilenamecheck;6. Once done, start the MRP on the standby database
alter database recover managed standby database disconnect from session;

Duplicate from Active database

Hi,
I have RAC primary database running in 11.2.0.3 with linux 5(dc). We also have configured RAC cluster on DR site recently.Now we need to create stanby database on DR site.
For this is have following doubts
My database size is 6TB(from dba_segmnets) and total is 14TB(from dba_data_files)
1) How duplicate of active database works internally? Does it copy the exact file to standby site for example copy datafile(which is of 5GB in size) and send it over to standby over network?
2) Both primary and standby sites are in different states, so i was thinking to backup the primary database first to tapes and then courier tapes to dr site and then finally restore and recover standby.
I have doubts in above approaches which should i implement. I think active database duplication will skip a)backup time b) courier time. Is that correct?
However if my database size is 14TB and using 1st method, does it send files to dr worth of 14TB size?

I am working on active database duplication and has below issue. Can any one help me on this?

No archivelogs were purged or backed up and the current logs were retained....so im somewhat confused....i am not restoring from backup but running active duplicate...
should I re-run the command with:

This fails saying that "ORA-12528: TNS:listener: all appropriate instances are blocking new connections" which is quite normal given that the listener is havig a handle in BLOCKED state for this AUXDB as it is in NOMOUNT state.
Could you please help me on how to proceed?
One option can be to create the controlfile manually and mount the instance before doing the duplicate. I hope Rman can continue from there.
Another option is to go for backup based duplicate.
Is there any other way to go?
Provide static registration on AUXILIARY side for your auxiliary instance and try again.For example change listener.ora file as
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = AUXDB)
      (ORACLE_HOME = <your oracle home>)
      (SID_NAME = AUXDB)
LISTENER =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = <auxiliary host/ip>)(PORT = 1521))
)And restart listener on auxiliary host then try again

This would be a database duplication from backup with RMAN. A Catalog will help, particularly as you are working in a Data Guard environment, but it is a straightforward and well documented operation:

RMAN duplicate from ACTIVE DATABASE

Hi,
I am trying to create a new 11.2.0.1 database by duplicating an existing 11.2.0.1 database using Rman with 'from active database' option.
I have created a password file and listener is configured as well.

rman
connect target sys/pwd123@SRCDB
connect auxiliary sys/pwd123@AUXDB
duplicate target database to AUXDB
FROM ACTIVE DATABASE;
This fails saying that "ORA-12528: TNS:listener: all appropriate instances are blocking new connections" which is quite normal given that the listener is havig a handle in BLOCKED state for this AUXDB as it is in NOMOUNT state.

Hi,
When you copy files of standby server to another target server ? - Yesterday.
Is standby is SYNC with primary? or MRP is still running? - ---------yes, standby db is running fine .
Even you can open database with resetlogs after recreating controlfile, no need of recovery too -- >I was unable to open . So went to apply arch files.
Do you have archive of thread 1 is in sequence #57887, -- No , Because sequence 57887 yet generate. I have applied all recent available archive log files.

Recover Primary Database from Standby Database

Hi all,
I'm trying to understand how to use physical standby database in order to have a backup from a primary database.
The first part is very clear. I supose I have a physical standby database ready and archiving from a primary database but the second part is the problem.
1. Now I supose that my primary database is gone... not just a logical corruption but a physical disaster such a fire o something worst.
How to recover the primary site from the physical standby database??????????
2. Just a logical corruption in primary database. How to syncronize with the standby database that it's the one who has the right data???
Thanks in advance.

How to recover the primary site from the physical standby database?1. Ensure that you DO have a Primary Site up and running. It might be the same building. It might be another building. Management might decide to switch to another city. (BTW, all of this should be defined in the D.R. / B.C.P. documentation).
The (possibly new) Primary Site has to have the required hardware , O.S etc.
2. Take a backup of the Standby and restore it to the (possibly new) Primary.
Actually, the Standby becomes the new Primary and the new site that is setup becomes the Standby. This continues until management decides to switch over.
Just a logical corruption in primary database.Take a backup of the Standby and restore it to the Primary. You have to suffer an outage. Note : If only one or few files on the Primary are physically corrupt (and offline), you could backup the selected files from the Standby and RESTORE and RECOVER on the Primary !

Failover from standby database to primary database

Hi,
Can anyone suggest me, How to do " Standby DataGuard database to primary database (dataguard)".
Kindly Give me steps.
Thanks,
Shweta

Hi
Follow these steps
Oracle switchover operation:
1.     Check and verify the role parameter on the v$parameters both primary and standby
On Primary
Log_archive_dest_1=”this is the local archive destination”
+Log_archive_dest_2=”This is the Service [TNS ENTRY]”+
Log_archive_dest_state_1=Enable
Log_archive_dest_state_2=Enable
Fal_server=”this should have the tns entry for the standby
Fal_Client=”this should have the tns entry for the primary
Standby_archive_dest=”This should have the Location where the archive located”
Standby_File_Management=AUTO
On Standby
Log_archive_dest_1=”this is the local archive destination”
+Log_archive_dest_2=”This is the Service [TNS ENTRY]”+
Log_archive_dest_state_1=Enable
Log_archive_dest_state_2=DEfer
Fal_server=”this should have the tns entry for the primary
Fal_Client=”this should have the tns entry for the standby
Standby_archive_dest=”This should have the Location where the archive located”
Standby_File_Management=AUTO
2.     Down all the applications connects to the database
3.     Shutdown both primary and standby databases
4.     For RAC Keep Only one primary and One standby up and all other nodes should be down
5.     Check the Primary database on Open mode and the Standby database on mount stage
6.     On Primary
SQL>select switchover_status from v$database;Sessions Active or To standby will be appearing on the result
SQL> alter database commit to switchover to standby with session shutdown;
SQL> shutdown Immediate;
SQL>startup nomount;
SQL>alter database mount standby database;
SQL>Alter system set log_Archive_dest_state_2=defer;7.     On Standby
SQL>select switchover_status from v$database;it is acceptable to have Sessions Active or To Primary
SQL>alter database commit to switchover to primary with session shutdown;
SQL>shutdown immediate;
SQL>Startup;
SQL.>Alter system set log_archive_dest_state_2=enable;8.     On Primary
start the managed recovery
SQL>Alter database recover managed standby database disconnect from session;9.     Check the log shipment is working from New Primary to New Standby Using
SQL>Alter system switch logfile; ---- On New Primary.check the alert log on both Primary and Standby for the log shipment and Media recovery.
10.     If the switch over fail issue the following statement on standby (ORACLE 9i)
SQL> alter database recover managed standby database finish skip standby logfile ┘
SQL> alter database commit to switchover to primary┘
SQL> shutdown immediate;
SQL> Startup;11.     If this don’t work please issue the below statement
SQL> alter database activate standby database skip standby logfile;12.     If the switch over fail issue the following statement on standby (ORACLE 10g and above)
SQL> alter database recover managed standby database finish force;
SQL> alter database commit to switchover to primary;
SQL> alter database open;
SQL> shutdown Immediate;
SQL> startup;13. Added the temp file to your temp tablespace
If you follow the steps (10,11 & 12 ) you have to recreate the standby again. those steps are actually fail over steps. Hope this will be helpful
Cheers

Error when trying to recover datafile from standby database to primary

hi friends,
getting problem with restoring datafile from backupset taken on standby database to primary database.
os: windows server 2003
db: oracle 11gR1(11.1.0.6)
i've configured standby database on two different hosts.
host1 - primary (db_uinque_name= prod)
host2 - standby (db_uniue_name= prodsby)
I've configure both database with recovery catalog. I take backup on standby database. users' datafile of primary database has been lost.i'm trying to restore from the backupsets taken on standby database.
with the help of - http://download.oracle.com/docs/cd/B28359_01/server.111/b28294/rman.htm#BAJCEFEG
on primary
c:\>rman target sys/password catalog rcat/password
rman>list backup for db_unique_name prodsby;
display the backupsets
rman>restore datafile 4;

hi.
Its not necessary its a otherway around to recover datafile from this backupset and apply archivelogs to make datafile consistent.
yes, it ain't the right way to restore backup to primary location.
so how would i connect to standby database with primary and recovery catalog.
i need to connect to recovery catalog and primary site because i need to restore to primary location and recovery catalog contain all metadata and backupsets related information.
i also tried the following steps from oracle documentation.
Connect to the standby database as the target database:
CONNECT TARGET sys@standby
You are prompted for a password:
target database Password: password
Connect to the primary database as the auxiliary database:
CONNECT AUXILIARY sys@primary
You are prompted for a password:
target database Password: password
Back up the datafile on the standby host across the network to a location on the primary host. For example, suppose that /disk1/df2.dbf is the name of datafile 2 on the standby host. Suppose that /disk8/datafile2.dbf is the name of datafile 2 on the primary host. The following command would copy datafile 2 over the network to /disk9/df2copy.dbf:
BACKUP AS COPY DATAFILE 2 AUXILIARY FORMAT '/disk9/df2copy.dbf';
Starting backup at 06-NOV-08
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=1068 device type=DISK
channel ORA_DISK_1: starting datafile copy
input datafile file number=00004 name=C:\APP\ADMINISTRATOR\ORADATA\prod\USERS01.
