Creating logical standby from non primary backup

We want to test creation for logical standby in our test enviroment.
Here is the plan we are
1. Backup Prod.
2. Restore Test Primary (T1) and Restore test standby (T2) from Prod backup.
3. Setup standby between T1 and T2.
Plan is to save the time for backup and restore process. I have not doe it before. Will this process work or T2 restore needs to be done from backup of T1 as that would be primary.

Thanks Tobi.
I will try this. The test system is very large about 16TB and the backup/restore process takes days. I just wanted to be sure if the same backup would work for creating the primary and standby at the same time.
So in this case, I will just have to restore from backup and move forward with archivelogs. Will I have to use the control-file from Prod or from T1.
Use the control file from T1(test primary)
I would like to use the backup COPY.
General steps to follow:
1. restore T1 as the (test)primary DB.
2. recover/apply the T1 using the redo log.
3. restore T2 but do not apply redo to prevent it from divergence from T1. i mean, let T2 scn be behind T1 scn.
4. following the general steps as it apply to you in preparing and creating primary and standby DB
http://docs.oracle.com/cd/B19306_01/server.102/b14239/create_ps.htm
5. make sure T2 can receive and apply redo data from T1
6.covert T2 to logical standby DB

Create logical standby from existing physical standby on 9i

I have physical standby database 9i running.
I want to try to convert the physical standby to logical standby. i follow the step by step in metalink document no. 748595.1
But I cannot do the 6th step:
6. Issue command to switch physical standby to logical standby after changing db_name in pfile to logical standby name. Shutdown the standby database if mounted and mount the database again. In this configuration, logical standby database name is LGSTDBY.
sql>alter database recover to logical standby LGSTDBY;
alter database recover to logical standby LGSTDBY;
Error at line 1:
ORA-00905: missing keyword
I have tried to create pfile from spfile on stanby and change the db_name to lgstdby.
I started nomount using pfile. I still cannot run the command.
I tried to mount the standby database but error occured:
ORA-01103: database name 'PRIMARY' in controlfile is not 'LGSTDBY'
The document in metalink is for 10.2.0.4
Is it possible to do it at 9i??
Thx for the help...

Regards, Anirban

After your RESTORE the (standby) controlfile, you must MOUNT the database instance with "ALTER DATABASE MOUNT".
You can also then query the controlfile with a "LIST BACKUP" or "LIST BACKUP SUMMARY" in RMAN to see if the deseired backups have been cataloged in the controlfile.
Don't specify the format for the ALLOCATE CHANNEL when you RESTORE DATABASE. In fact, you don't need to ALLOCATE CHANNEL at all when the device type is the default value of DISK if your are on 10gR2 or above.

REcreate physical standby from New Primary

Dear Experts;
My Production db 11G R1 os was crashed so I had to trigger failover at my physical standby (New Primary).
I recreated Crashed Primary as Standby from New Primary mentioned above with Hot backup
Now question is that I have successfully Switched to my old primary (Crashed one) but the New Primary crashed (old Standby).
I have tried rman duplicate it restores my datafiles but THE Number of LOG MEMBERS IS NOT the same as in Primary.

It is not problem.
Online redo members of groups or group count, may be is different primary and standby databases.
If you want learn which member is which group, the try below script.
select member, group# from v$logfile;
{coide}
I think there have 2 member every log group.
Every standby redo log group heve only one member, It is recommended.

Imran,
The information from alert log file is not sufficient.
Can you log switch on primary and monitor whether it is archiving in standby or not.
and you can monitor the changes in "v$managed_standby"
Also check for the errors using "v$dataguard_status"

It seems standby changed to primary which was not desired.

Not tried myself, but you might want to have a look at this URL.
It appears to suggest that you need to change names of datafiles as well as value db_name explcitly on standby.

Create a standby controlfile using cold backup

Hi All,
We have to setup a DR for a production database.
Here we have the coldbackup which backups all the datafiles and the control file from the production database.
For cloining we generally copy them to another instance and then create controlfile manually. But for setting up as a DR , we would be creating it for standby controlfile.
I tried to google but I am not able to find a way to create a standby controlfile from the existing controlfile cold backup.

You need to:
- create a SPFILE manually for standby database
- use the RMAN command: DUPLICATE TARGET DATABASE FOR STANDBY
- remove all SPFILE statements from RMAN script.

Hi experts,
This is my first time configuring a Standby (Data Guard) scenario for our Oracle data base. The platform used is Solaris 10 with Oracle 10g.
After reviewing a lot of documents and tutorials regarding this matter still have some doubts on how to get this scenario finally configured.
Basically I would like some confirmations regarding the following point. We have the new db already installed in our disaster recovery site and the next step I need to do is to perform an offline backup from our primary data base and then transfer that backup to our standby database. Iu2019m currently stuck in this steps since Iu2019m not completely sure on how proceed with this specific step. According to the following link http://help.sap.com/saphelp_nw04s/helpdata/en/08/5744b84ae611d1894f0000e829fbbd/content.htm , the following steps are necessary:
       1.      Take a backup (online or offline) of the data files of the production database
       2.      Create a control file at the production site to be used at the standby site, by entering the following command:
alter database create standby controlfile as <filename>
       3.      Archive the current online redo log of the production database, by entering the following command:
alter system archive log current
       4.      Transfer the backed up data files, the control file and all archived redo log files to the standby site.
Regarding the above step u201C4u201D... Could someone please detail me what all the data files are? As per SAP System Copy guide in its section u201CRestoring Database Files on the Target Systemu201D the following is indicated...and I think these are the files to transfers to the standby db.
Files/oracle/<DBSID>/sapdata<x>
All files/oracle/<DBSID>/origlog<x>
All files/oracle/<DBSID>/mirrlog<x>
Is my assumption correct?
Please let me know which the correct steps are and if any other process is applicable or advisable over the above mentioned....let me know.
Regards

Hi,
As far as cold backup of database is concerned, backup of the folders you have mentioned is enough.
Hope you have created a parameter file for the standby database and changed the primary parameter file as part of preparation of primary database.
Here is a sample entry you have to have on standby parameter file apart from other entries..
db_unique_name='STANDBY'
fal_client='STANDBY'
fal_server='PRIMARY'
log_archive_config='DG_CONFIG=(PRIMARY,STANDBY)'
Also browse through the following threads...it may help..

How to Refresh UAT Primary/standby from Production primary/standby

Hi ,
We have the following setup :
Primary/standby - Production
Primary/Standby - UAT
I need to know the process on how to refresh the UAT primary/standby .
I'm thinking on the following lines :
1] If we have the export dump of production , can we go ahead and drop the schemas to be refreshed on both UAT Primary and UAT Standby UAT then perform the schema import on Primary UAT .
2] In case if I have to do a full refresh of UAT , do I need to rebuild the UAT environment from the proudction backups Ie,
(i) Drop both the UAT primary and UAT standby database .
(ii) using the produciton backup built the UAT Primary . Take the UAT primary backup and build the UAT standby .
Appricaite if any one can provide some best practices to refresh UAT from Production.

That setup seems to be rare. We assume that the Standby Database is used for testing and have a feature for that called Snapshot Standby.
But in your scenario, you need to develop your own techniques for "refreshment of the UAT Primary".
An easy way (if your Primary is not too large): Throw away your UAT env each time the "Production Primary" changes and RMAN clone it to "UAT Primary" then.
Then RMAN duplicate "UAT Standby" again. Could be relatively easily scripted.
But again: Why not just create an ordinary Standby on your UAT hardware and use it for testing with Snapshot Standby feature? Much easier to maintain.
Kind regards

Can Grid Control 10gR2 create a standby database when primary db uses ASM?

Does anyone know if Grid Control 10gR2 will be able to create a standby database when the primary database uses ASM for data files, redo log files, and archive log files but the standby database will use mounted disks? If it can, would it matter that the primary db will be a RAC cluster and the standby will be a single instance db?

I appreciate your reply and hope you are correct. Have you had a look at the 10gR2 Grid Control to confirm this or are you only going on published statements? The reason I ask is because previous versions of Grid Control claimed to support ASM but they would only allow you to work with them AFTER you had created a standby database manually but you couldn't actually use Grid Control to create a standby database from a primary database that had its log files on ASM disks.

Logical standby problem on primary DB updates

Hi all!
I am quite new to standby databases, but I managed to sucessfully setup logical standby (11g on linux).
However, I got some problem - when I try to insert some data into Primary DB using simple JDBC statements, I sometimes get exception:
java.sql.SQLException: ORA-16224: Database Guard is enabled
And this happens not all the time - sometimes I can insert and commit, but sometimes I get exception.
This never happens when I am trying to insert data directly from sqlplus or TOAD.
looks to me like java application sometimes is connecting to standby database.
any suggestions?
Thanks

Check for example, whether both DBs present the same service and whether you have an oracle net configuration like
myservice =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host_A)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = host_B)(PORT = 1521))
      (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = myservice)
)You should make sure that the productive service is only presented by the primary database. See this explanation:
