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 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.

How to create a clone of database from STANDBY?

How can i clone a database from physical standby database?

Steps to clone from standby:
1. cancle the managed recovery process on standby
sql>alter database recover managed standby database cancel;
2. Remember your standby databse would be in mount mode.
3. Connect to the auxiliary instance and to the standby database through RMAN
rman target sys/<pwd>@standby auxiliary sys/<pwd>@auxiliary-connection
4. If 11g, then run directly duplicate from active database
rman>duplicate target database to 'auxiliary_db_name' from active database nofilenamecheck;
5. Once, the duplication is done, start the MRP on the standby again
sql>alter database recover managed standby database disconnect from session;
Ok..You are on 10g.
Perform the above steps, but only thing is 1st you need to take the backup of the standby database first.

Shrink Log file in log shipping and change the database state from Standby to No recovery mode

Hello all,
I have configured sql server 2008 R2 log shipping for some databases and I have two issues:
can I shrink the log file for these databases: If I change the primary database from full to simple and shrink the log file then change it back to full recovery mode the log shipping will fail, I've seen some answers talked about using "No
Truncate" option, but as I know this option will not affect the log file and it will shrink the data file only.
I also can't create maintenance to reconfigure the log shipping every time I want to shrink the log file because the database size is huge and it will take time to restore in the DR site, so the reconfiguration
is not an option :(
how can I change the secondary database state from Standby to No recovery mode? I tried to change it from the wizard and wait until the next restore for the transaction log backup, but the job failed and the error was: "the step failed". I need
to do this to change the mdf and ldf file location for the secondary databases.
can any one help?
Thanks in advance,

1. If you change recovery model of database in logshipping to simple and back to full Logshipping will break and logs wont be resored on Secondary server as log chain will be broken.You can shrink log file of primary database but why would you need that
what is schedule of log backup. Frequent log backup is already taking care of log files why to shrink it and create performance load on system when log file will ultimately grow and since because instant file initilaization is not for Log files it takes time
to grow and thus slows performace.
You said you want to shrink as Database size is huge is it huge or does it have lots of free space. dont worry about data file free space it will eventually be utilized by SQL server when more data comes
2. You are following wrong method changing state to no recovery would not even allow you to run select queries which you can run in Standby mode. Please refer below link to move Secondary data and log files

Migrate from UAT database to Production database

Hi all,
I need to set up my production database based on the UAT database.I would like to re-generate all my objects script and grant scripts from UAT so that there will not be any discripency. I can't go for full db export due to some apps constraints.I'm planing to generate grant scripts from dba_tab_privs for each role and generate public synonym script from dba_objects for each user.Object inventory can be taken from dba_objects for each user. FK and PK constraints are another worry.
Am I on a right path?? My worry is that, I may miss out something. Can anyone guide me?

I think Bhandari's advice is good as long your UAT and PRODUCTION on the same OSWhat about the data? UAT is going to full of rubbish data that nobody would want in a production system. But you wouldn't want to zap it from UAT because you'll need it for the next release (patch, enhancement, whatever). So you copy it all over into Production and then remove everything that's not supposed to be there? Starting a release by trashing the data in production doesn't sound very clever to me. Furthermore it's a complete non-starter for managing an incremental release.
Using Import/Export isn't much better. Neither is generating scripts from the UAT data dictionary. Forget about Release 1.0! Think about how you're going to manage 1.1!
The simplest, the least effort, the most robust approach is to create Production from the scripts that were used to build UAT. Anything else is more complicated, more work, less reliable. The only reasons why anybody might need to take some other approach are because they didn't build UAT entirely with scripts or because they didn't subject those scripts to source control. And that's what I mean by bad processes.
LALEAGTFOTP!
Cheers, APC

Deleting applied archives from standby

Hello Guys,
We have oracle 10g rel 2 on hp-ux
I feel this common question for dataguard implementation
Just want to check best way of deleting archives automatically from standby database,i have 2 methods in mind
as below
1)At os level shell script-finding last seqno from alert log at standby/or query v$views(select max(sequence#) from v$archived_log) ,passing it to script
using rman as :*delete archivelog until sequence seqno;*
or deleting at os level upto this seqno
(Making script is not issue with this functionality and scheduling it in cron)
2)by RMAN at standby
set alter system set "_log_deletion_policy"='ALL' scope=spfile;
set CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
however i have no plans to take backup at standby,still can i use above command
is it reliable i faced some issues in past inspite of this configurations archives were not deleted at standby
Please give your views is there any other method to delete archives automatically ,and which one is more preferred
and reliable method/best method
Thanks

logdeletion_policy parameter is static, so which you cant change dynamically, PRimary should bounce, If it is fine then you can go ahead.
If you do not have time, then prepare an RMAN script to delete the archives.

Archive sequence number from standby does not match primary

I have two unix servers configured, one as primary and one as standby, both in 11.2.0.2. When I run the verification scripts, I noticed that my standby's archive log sequence does not match the primary.
From standby:
select database_role, open_mode from v$database; Result: PHYSICAL STANDBY, MOUNTED
select max(sequence#) from v$archived_log; Result is null
archive log list;Database log mode Archive Mode
Automatic archival Enabled
Archive destination /arch/standby
Oldest online log sequence 0
Next log sequence to archive 0
Current log sequence 0

Hello;
I don't think you have Data Guard working.
select max(sequence#) from v$archived_log; This should return a number.
Do an alter system switch logfile; on the primary, I'm thinking the new log never makes it to your standby.
Once you have this working consider running something like this from your Primary:
SELECT name as STANDBY, SEQUENCE#, applied, completion_time from v$archived_log WHERE DEST_ID = 2 AND NEXT_TIME > SYSDATE -1;
select max(sequence#) from v$archived_log where NEXT_TIME > sysdate -1;
You can change the first query to include both the Primary and the Standby.

Clone from standby ended in ARC: Cannot archive online log based on backup

Hi
I m into scenario where my prod db is in one data center and standby is in other data center.
Both are geographically separated. I have to get a copy of prod on to standby data center side.
Sending data over the network is taking long time either with duplicate db from active db or take backup and copy over standby side and restore it.
so i thought of duplicate db from standby db which is in same data center, using 11g RMAN duplicate from active standby command.
I have simulated scenario which is as below
oracle version 11.2.0.1
os version REHL 5.4
My procedure & parameter are as below.
on standby side from where i m copying (TARGET)
1) on standby
alter database recover managed standby db cancel;
2)alter database convert to snapshot standby;
which gave me

and it fill up whole fs. and finally duplicate command throws error.
not sure what i m missing of inside duplicate command or is it valid to duplicate database from snapshot standby.
can somebody light on it please

TSPITR using backups from standby

Hi,
I would like to ask for your opinion/advice regarding the following
scenario. We have a primary 10.2.0.3 RAC database which has a physical
standby database, both sites being managed through dataguard. Every
night full RMAN backups are taken for the primary and standby
databases. Between the primary and standby sites we do not have any
shared storage like NFS or SAMBA (because of the problems mentioned
into Note:413098.1).
Now, as far as I know, backups of datafiles/archives taken from the
standby can be used on primary, am I right? So, what I would like to
achieve is to perform a TSPITR of one particular tablespace by taking
a backup control file from the primary but using datafile copies and
archives from the standby. And of course, because I don't want to load
too much the primary, the auxiliary instance should be located on the
standby machine. Is this possible? Has anybody tried this before?
Many thanks!
talek.

if you are on 10.2.0.3, check this document and make use of Incrementally Updated Backups: Rolling Forward Image Copy Backup
http://download-east.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup004.htm
You can restore datafiles backedup from physical standby
can restore archivelogs created on physical standby
but can not use control file from standby to recover on primary
You should be able to use bakcup from a physical standby and recover any tablespace in Point In Time on priamry prvovided you have a backup/datafile copy before and archives untill that time.

Recover from Standby

Hi all
I have a standby database and I want to recover this database in other computer...
Which steps I must pass?
1. Shutdown database
2. Copy files from Standby database to my local database
3. Open database and activate it as a primary database
Am I right??
Thanks...

I have a master database which users are working on it.
And I have standby database in shutdown mode, which I applying on it my archive log files
I want to create a backup of my master but don't want online backup. And I can't do offline backup due to users working. And that's why I want to take a copy from standby database and create the same database on my another test machine..
Can I do it and how??

USB ports don't work after resuming from standby with Windows 8 on X230 tablet

I have just done a clean install of Windows 8 on my X230 tablet. Before installing Windows 8 I installed the most recent BIOS for this machine (version 2.50). After installing Windows 8 I installed System Update from the Lenovo Website and downloaded all the recommended drivers and other files. I've also installed all the latest Windows 8 updates.
Here are the symptoms of my problem: After resuming from standby/sleep mode, my USB ports do not work. My computer has two USB 3.0 ports and one USB 2.0 ports. All exhibit the same behavior. After resuming from standby mode I have tried inserting both my mouse and a USB thumbdrive, but neither are recognized. After restarting Windows, the USB ports work again... until I resume from standby mode again.
I hope there is a solution to this issue. It is very frustrating.

Thanks for the suggestion about tweaking the "Allow this computer to turn off this device" feature. I un-checked that box for every entry I could find under "Universal Serial Bus Controllers" in the Devide Manager. Unfortunately, the same symptoms of my problem persisted.
I went back and looked at the README file associated with the BIOS 2.50 download on Lenvo's support site. At the bottom of the file it gives a "Summary of Changes". Under version 2.03 of the BIOS (the version just before version 2.50), it says:
- (Fix) Fixed an issue where USB device might not detected when system resume from sleep mode.
This indicates that Lenovo support was already aware of such issues. The problem was intended to be fixed in version 2.03 of the BIOS. However, the issue persists on my machine, even with the latest BIOS.
Hopefully someone from Lenovo can comment here.
