i have setup the OEM-Dataguard in order to duplicate the DB instance from the primary to the standby DB in the standby server.At first I installed oracle server in Server A (Primary) created DB instance of SCT, in archivelog mode and then I install the oracle binary in Server B (standby) and made 2 servers ORACLE_HOME the same and also I installed OEM agents on the 2 servers and registered successfully to the OEM server.
I then used the dataguard to do the initial backup of the DB in server A and but when I specify the standby DB location, it prompt me the following error.

Examine and correct the following error(s), then retry the operation.

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.)

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:

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

We are planning to setup a data guard (Maximum performance configuration ) between two Oracle 9i databases on two different servers.
The archive logs on the primary servers are deleted via a RMAN job bases on a policy , just wondering how I should delete the archive logs that are shipped to the standby.
Is putting a cron job on the standby to delete archive logs that are say 2 days old the proper approach or is there a built in data guard option that would some how allow archive logs that are no longer needed or are two days old deleted automatically.

I've a primary database and a physical standby.Logs are shipping perfectly from primary to standby.The logs that are applied on the standby are getting stored in a mount point(LINUX-/opt2) which consumes more space(160 GB). Will that be right if I go ahead and delete them?
My rman configurations in primary is:
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 4;
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;

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.

We have a 11r2 primary and standby running on RHEL 5. The primary lost network connectivity for a time and VMWare locked up. The VM admin restarted the primary VM (it was a hard-boot). This all happened while I was gone and when I came into work, the primary database appeared to be working. I decided to dig deeper and check out the standby. On the standby...

My oracle version is 11.2.0.2 RAC RDBMS on RHEL 5.6.
At my standby site my physical standby database is on 4 node cluster with all 4 instances up. I need to disable 3,4 instances so that we want it to run on only 1,2 instances.To disable the instances do i need to stop apply(mrp) process. And the apply node is node 1.
