Step by Step – Duplicating Oracle Database using RMAN Backup with connection to Target database

Step by Step – Duplicating Oracle Database using RMAN Backup with connection to Target database
Step by Step Duplicating Oracle Database using RMAN Backup with connection to Target database:-
Details:

Oracle EE 11.2 on RHEL5
Target Server: 192.168.195.128
Clone Server: 192.168.195.137

As we are duplicating to a different we can use same SID for both Source and Clone. My source DBID is HCL

Step1. Put your target database in Archive log mode.

Step2. Start RMAN at Target and Configure CONTROLFILE AUTOBACKUP ON
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;

Take Backup of Target database
RMAN> BACKUP DATABASE PLUS ARCHIVELOG

Step3. Configure tnsnames and listener at source and clone server as below:

At Source Server
——————————————————————–
HCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.137)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = HCL)
)
)
———————————————————————
At Clone Server
———————————————————————-
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = HCL)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = HCL)
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.137)(PORT = 1521))
)
————————————————————————

Step4: create orapwd file at clone server’s dbs directory
orapwd file=orapwHCL password=oracle entries=10

Step5. Create pfile of Target database and copy pfile to Clone Server’s dbs directory
SQL> create pfile from spfile;

Copy pfile to Clone Server
scp oracle@192.168.195.128:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initHCL.ora /u01/app/oracle/product/11.2.0/dbhome_1/dbs/

Step6. Create required directories at Clone server. Here I’m using same filesystem as source so no need to use DB_FILE_NAME_CONVERT

mkdir -p /u01/app/oracle/oradata/HCL
mkdir -p /u01/app/oracle/flash_recovery_area/HCL
mkdir -p /u01/app/oracle/admin/HCL
cd /u01/app/oracle/admin/HCL
mkdir adump dpdump

Step7. Copy backupfile to Clone Server from Source Server
scp -r oracle@192.168.195.128:/u01/app/oracle/flash_recovery_area/HCL/ /u01/app/oracle/flash_recovery_area/

Step8. At Remote Server set ORACLE_SID=HCL and start the Clone Server in NOMOUNT mode
SQL> STARTUP NOMOUNT;

Step9: start RMAN at source and connect RMAN to clone as well
At Source
RMAN TARGET /
connect auxiliary sys/oracle@HCL

***Make sure your Souce Database is in OPEN mode and Clone DB is in NOMOUNT Mode

Now run the Duplicate command # See the response as well
