Data Guard :: Unable To Create Physical Standby Database Using RMAN?
Nov 4, 2010
why RMAN is unable to create physical standby database ?
RMAN> connect auxiliary sys/system@DGREPL
connected to auxiliary database: DGREPL (not mounted)
RMAN> connect target sys/system@REPL
connected to target database: REPL (DBID=2730563515)
RMAN> run{
allocate channel prmy1 type disk;
allocate channel prmy2 type disk;
allocate channel prmy3 type disk;
allocate channel prmy4 type disk;

I would need to create a physical standby database for DR without using data guard. I like to know in more details like
1. What would be required to switch over to standby database in case of failure of primary database? Is it going to be a manual process each time, or can be automated using scripts?
2. How the archive logs will be applied to standby database in timely manner to sync with primary database?
3. How the Primary database will be synch with Standby database once the issue resolved on primary database.
4. Where do I get a complete script to create physical standby database on Windows platform?

I am trying to create the Standby database using RMAN.
I have first created an auxiliary instance followed by the password file for the instance and the registering it it listener.
Below are the parameters of the pfile of the standby database and followed by the command issued at the RMAN prompt.
PFILE parameters [STANDBY]

I have dataguard configuration operating in maximum availability mode with a local standby db (A - lgwr sync not using real time apply) and a remote standby db (B - lgwr async). I then simualted a crash of my primary database with batch jobs running. Since the stby db A is in lgwr sync option ,all the commited data in the current online redo log has been transmitted to stby A and is present in its stby redo log (Group 2).How do I apply this stby redo log to the remote stby db.
Tried the following methods.
1.ftp the stby redo log to the remote db and tried to regiter it, got an error that it is not completely archived.
2.issued the recover standby database command and supplied the stby redo log when it asked for the sequence in the stby redo, got an error saying there is corruption in a block(tried this option multiple times ended up with the same result.)

I have set up a single instance standbys for rac databases. Now, I need to offload the backups from the primary on to the standbys.
1. cancel managed recovery
2. connect to target(standby) and catalog and backup the standby
3. put standby in managed recovery mode.
I think following these steps, I can restore primary(?). Now, My question is, how can I use these standby backups to clone/refresh databases? I tried it by connecting to target(primary), catalog and auxiliary but rman is using the primary backups instead of standby's to refresh the auxiliary database.

I am using Oracle RAC 11.2.0.3 as primary database, we are going to start using Oracle data guard. So I am designing my infrastructure and planing to use Oracle 11.2.0.3 Single instance as my physical stand by database.
My question is it feasible to have my standby database as single instance while the primary is RAC? is it feasible to build my Oracle single instance standby database from the RMAN backup of the RAC primary database? Is there any restrictions (or any points to be taken into consideration) since my primary database is RAC while the physical standby is Oracle single instance?
in the below link
[URL].......
it was mentioned that primary can be RAC or single and same for standby, but my question is it feasible to have primary as RAC while standby as single instance? or it should be like each others?
The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters (RAC) database. Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle RAC database.

My steps for testing as below:
1.create a primary database
2.duplicate a physical standby database;
3.turn on flashback on both databases.
4.record SCN xxx on physical standby database.
5.convert physical standby to logical standby (using keep identity statement)
6.flashback to logical standby to xxx
7.convert logical standby to physical standby
8.using real time apply I got errors: Fast Parallel Media Recovery enabledManaged Standby Recovery starting Real Time ApplyMRP0:

create another standby database on a new server.
I'm running Oracle 11.2 EE on Solaris 10.
We already have one standby database, but now, I want to create another standby database on another server, which ultimately I will make primary and then replace and destroy our current primary/standby databases.
Also, just for the heck of it, I tried to look in our DB Console, and the "Add standby database" is grey'd out.
Is this because I am only using DB Console, and not Grid?But if that were the case, why would the option even be in DB Console, or perhaps is there a lmiitation to the number of standby databases you can manage with DB Console?

I have an issue whereby our standby instance was down for a couple of days and when it came back online we found an archivelog file was missing, so recovery only happened up to a point. It appears that the archivelog was deleted therefore we are unable to continue with this standby. We are now planning to rebuild the standby database. As far as i know all of the steps originally performed need not be performed to complete this task.
1. Shutdown standby
2. Delete all datafiles & redo logs
3. Copy over datafiles to respective directories
4. Copy online logs and archivelogs to standby.
5. Create a control file for standby database
6. Startup mount standby database
7. start redo apply

Today, I am learning dataguard 11.2.0.1. The docs said:A. Monitoring Standby DB Application of redo logs may be monitored by issuing the SQL command:
SQL> select client_dbid, process, sequence#, status from v$managed_standby;
In the primary database, the sequence# with the status “WRITING” would refer to the current redo log sequence#In the standby database, if the status of the process MRPO is “APPLYING LOG” and the status of the process LGWR is “IDLE”, then application of redo logs is up to dateI see that that MRPO at standby is "WAIT_FOR_GAP". How do I resolve this gap.

I use windows 2003 server, oracle 10.2.0.4.0.My question is related to maintaing a standby database
1. Do we need to take RMAN full backup of standby database on a regular basis? At the moment I dont take backups of standby database.
2. I have FRA on standby database. The archivelogs from primary go to FRA on standby. I delete my archivelogs as follows:
DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-3';
Though the archivelogs are delete there are still empty folders of archivelogs that are not deleted. How to get rid of them automatically.

Suddenly I can't open any of my physical standby databases read only. Alert log snippet and trace files follow post. I'm running 9.2.0.1.0 on all hosts, which are running AIX 5.2. I've successfully opened all physical standby databases read only numerous times in the past. solve this? Is it possible that these standby databases cannot be switched over to primary should the need arise?
Here's how I typically open a physical standby database read only:
alter database recover managed standby database cancel;
alter database open read only;
