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.

Restore RMAN from different Database Rman backup

Hi Everybody
I am practicing Rman so I have one query that how to restore rman backup from another database.
For Example :
1. I have Rman backup of DB1 with level 0 and level 1 cumulative database plus archievelog
2. I need to import or restore Rman backup of DB1 to another database DB2.
What is the procedure for doing the above queries. Please anyone one help me out.
I have using oracle 10g r2 running in windows server 2003.
Thanks in advance.

These are the steps ; you need to write the appropiate commands for each step: Hope it helps!
1) Take appropriate RMAN backup of the database db1. Note that you should turn on the CONTROLFILE AUTOBACKUP configuration so that we have the controlfile backed up after the database backup. When we restore the controlfile on new host from this autobackup piece, it will have the information of the latest backup.
2) Create a PFILE for the destination database db2 using the database db1
3) Move the backup pieces and the modified INIT.ORA file to the new host. Starting from 10g it is NO longer compulsory to copy the RMAN backup pieces to exactly the same location on the new host as the production location.
4) Use the pfile created above to STARTUP NOMOUNT the database on the new host
5) Now invoke RMAN and restore the controlfile specifying the location where the controlfile autobackup piece is restored on this new server. You can mount the database once the controlfile is restored successfully.
6) You can skip this step if you have restored the RMAN backup pieces to exactly the same location they were backed up on database db1. If this is not the case then you need to catalog the RMAN backup pieces to make RMAN aware of thier new location on the new host. Note that CATALOG BACKUPPIECE command is available only starting from 10g.
7) Having determined the point up to which media recovery should run, start the restore/recovery using for example:
RMAN> run {
2> set until sequence 59 thread 1;
3> set newname for datafile 1 to '/new_location/system01.dbf';
4> set newname for datafile 2 to '/new_location/undotbs01.dbf';
5> set newname for datafile 3 to '/new_location/sysaux01.dbf';
6> set newname for datafile 4 to '/new_location/users01.dbf';
7> restore database;
8> switch datafile all;
9> recover database;
10> }

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;

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 !

Restoring backup of standby database

Hi,
I have an issue logging into my database as sysdba. I'm getting the error ORA-01031: Insufficient priveleges. Here are the facts surrounding the issue:
1. I have a backup (not a clone) of my standby database.
2. I am restoring this backup to a new server I just built.
3. The O/S version and directory structure is exactly the same as my source.
4. I've restored my backup to my new server. When I set the DB environment variable and then try to logon with sqlplus '/ as sysdba', I get ORA-01031.
Here's what I've already tried:
1. I've verified my SID and ORACLE_HOME are being set properly.
2. TWO_TASK is not set.
3. I have confirmed $ORACLE_HOME/rdbms/lib/config.c is correct.
4. I've performed all the checks on Metalink Note 69642.1.
I'm completely stumped at this time. I even rebuilt the whole thing from scratch just to ensure that I wasn't missing something. The only thing I can think of is that this is a standby database and it needs to be 'failed over'. However, I would still need to logon as sysdba for that so I'm still stuck.
Can anyone shed some light on what else I can check? My DB version is 10.2.0.4. running RHEL 4 Update 7. I'm also running EBS 11.5.10.2.
Thanks.
Aliyah.

Problem has been resolved. It turned out that I overlooked my config.c file. In there, my oracle user was not set to the dba group. So I had to change it, and relink the link. All is well now. Thanks.

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

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

UAT Database from Standby database

Hi,
I'm using oracle 11.2.0.2.0 on Windows 2008,
I have prod & standby databases, I want to create new UAT DB which wiil be same as prod,
How Can create a UAT using standby database cold backup,
can i use cold backup of standby database.
Thanks
Edited by: user10745179 on Oct 22, 2012 12:42 PM

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:

Restore datafile to standby database

dear all,
i have a standby database which use raw devices under solaris 9.
and a primary database which use filesystem under solaris 9 too.
recently i have a problem which is nologging issue. see ML 290161.1
my question is how we know that when restore to raw devices through rman, will it replace file in the raw?
or should I create new raw and directing my new restore to new raw?

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" ...

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.

Urgent -- need to restore table from full database backup

Hello,
Can somebody tell me the process for restoring just a table from a full database backup?
I did a full online database backup yesterday, and one of my tables got ruined today. I need to restore it as soon as possible, but I don't know how. When I tried flashback tables, it said that feature wasn't enabled. Should I restore the datafile or the tablespace?
Thanks much,
Nora

If you only want to recover the table and not the other objects in the tablespace, and assuming the table was damaged by a user statement (and not, say, block corruption), you would need to recover your backup to a different system, export the table that was damaged, and import the table into your real production database. If you can recover the entire tablespace to an earlier point in time, or if you can lose some committed changes to other database objects, you may have other options.

DG backup advisory , backup from standby database 11gr2

Hi everyone
I'm having a bit of issues with how the backups are setup in my DG environment. I have searched high and low and not really found a easy answer to how to setup your DG backups.
One says this, another says that. So i'm asking here in the forum.
What is the correct way to backup a DG environment? Some discussions just shows do a normal backup on the standby only, another says you must backup the controlfiles from the primary as well (this is where my problem starts)
We recently upgraded a 11gr1 DB to 11gr2 and now the old setup does not work anymore. The old setup was doing backup on standby , and spfile + controlfile backup on primary node. this now fails with ANU2614E Invalid sequence of function calls to Data Protection for Oracle (backup to tape)
This particular error happens when I run a backup controlfile on the primary before the backup on the standby. If I skip the controlfile backup on the primary, the standby will backup correctly, including the controlfile + spfile.
There is also a delete obsolete script running within each script (controlfile backup etc), might also cause issues I guess. But this worked fine in 11gr1.
So i'm reaching out, trying to figure out the proper way to do backup, everyone says different.
Sincerely
Johnny

What is the correct way to backup a DG environment?
Neither backing from Primary or Standby is more correct than the other.
You can use a backup taken on the Standby in order to restore and recover a Primary Database and vice versa.
Datafiles, Control files and archive backups are interchangeable in a Data Guard environment.
Where you backup should depend upon load. If the Primary can handle the load without causing a SLA issue then I would backup there.
The main things I would do with Data Guard and RMAN are as follows:
Enable Block Change Tracking.
Always use Autobackup.
Always use a FRA.
Keep Flashback Database on.
And always set this on the Primary ( CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY; )
ANU2614E Invalid sequence.
Odd, If you are using Third party software along with RMAN I might check this:
Rman fails ORA-19511 ANU2614E Invalid sequence of function calls to Data Protection for Oracle (Doc ID 1300134.1)
Otherwise I would open a support ticket ASAP.
