Oracle 11g RMAN DUPLICATE DATABASE WITHOUT TARGET CONNECTION

Here is the RMAN DUPLICATE DATABASE by using without a target connection and without a recovery catalog connection. 


I hope this short example will explain you about rman duplication database. 


Here is the example:


This is my below setting in TARGET DATABASE


RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;



new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters are successfully stored


RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'I:\Ora-Backup\DB001\CF_%F';


new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'I:\Ora-Backup\DB001\CF_%F';
new RMAN configuration parameters are successfully stored


RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'I:\Ora-Backup\DB001\BKP_%U';


new RMAN configuration parameters:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   'I:\Ora-Backup\DB001\BKP_%U';
new RMAN configuration parameters are successfully stored

Here is the complete full backup script on TARGET DATABASE

RMAN> run
2> {
3> backup database;
4> backup archivelog all;
5> }

Oracle 11g RMAN DUPLICATE DATABASE

Hello Friends, 


Happy New year !!!


This is my first post in 2011 year. [ may it's long time for me]. Now this is the time to share with you guys for Oracle 11g stuff. 


I would like to RMAN Backup / Recovery features in 11g. This will help you all to understand about oracle rman features in 11g { but not like oracle documentation :-) }


RMAN DUPLICATE DATABASE. 


In duplication database here is the three new features.


1. Duplication without a target database connection. Rman obtains metadata about backups from recovery catalog. 


2. Duplication without a target database connection and with out recovery catalog connection. Rman obtains metadata about backup from BACKUP LOCATION.


3. Duplication with a target database connection. Rman obtains metadata about backups from control file / Recovery catalog. 


let me test duplication database without a target database & without recovery catalog.
