Active Database Duplication

Active database Duplication using RMAN 11gR2

Using "Active database Duplication" method Incomplete-recovery "NOT" possible ( SET UNTIL time/sequence/cancel). Because this duplication method only based on  the logs are archived in the target database location . Even content in the online redologs  from the target database. So we no need to take the backup of  target database . but target database must be in archive log mode

 if the database size in TB's with network connection between database enabled. we can use this method.



target database  a.k.a (primary/source database)
auxiliary database a.k.a (destination/clone database)

Target database name: mydb
Auxiliary database name:  orcl
                            
                               

Overview:
             
1. Copy the password file from Target database to auxiliary database location
2. Create the pfile from target database for Auxilary database( if target has spfile create pfile from spfile)
3. Configure the linster & tnsname on both target database and auxiliary database  
4. Create the required directory structure in  Auxillary db location (based on pfile )
5. Open the database in mount mode using modified pfile 
6. Use rman command, RMAN will perform restore and recover the database.
$rman target sys/oracle@<target_dbname>
 RMAN> connect auxiliary sys/oracle@<auxiliary_dbname>
(or)
rman target sys/oracle@<target_dbname>  auxiliary sys/oracle@<auxiliary_dbname>
 5.RMAN>duplicate target database to <auxiliary_dbname> from active database nofilenamecheck;

After "Active database Duplication"  
1.Auxiliary DB has unique DBID
2.Auxiliary DB has Copy of data files & archived log files from target database  
3.Recreate the new control files for auxiliary database
4.Recreates the online redo log files.
5.Restart the auxiliary instance.
6.Open the database with RESETLOGS.
7. enable the database in archivelog mode 

STEP 1: Copy the password file from Target database to auxiliary database location

-bash-3.2$ scp orapwmydb oracle@192.168.168.2:/u01/app/oracle/product/11.2.0/db_1/dbs/orapworcl

orapwmydb           100%            1536      1.5KB/s         00:00    



STEP 2: Create the pfile from target database for Auxilary database( if target has spfile create pfile from spfile)

STEP 4: Create the required directory structure in  Auxillary db location

create the nessary directory structure based on the init file.
mkdir -p /u01/app/oracle/admin/orcl/adump
mkdir -p /u01/app/oracle/oradata/orcl/
mkdir -p /u01/app/oracle/fast_recovery_area/orcl
mkdir -p /u01/app/oracle/oradata/
mkdir -p /u02/archive/

STEP 5. Open the database in mount mode using modified pfile

Note: In Auxillary database location add entry in /etc/oratab

-bash-3.2$ . oraenv
ORACLE_SID = [11gR2_NEW] ? orcl
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 is /u01/app/oracle
