Create duplicate database using rman

You want to use RMAN to create a duplicate database on the same server by using RMAN backups.

Source database name is MYTEST

Target (duplicate) database name is MYDB

This is the simple steps to create a duplicate database

You can read from here http://mohamedazar.wordpress.com/2010/05/25/create-duplicate-database/

Step 1: Configure Listener.ora and tnsnames.ora files

tnsnames.ora file

MYTEST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mytest)
)
)

MYDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = mydb)
)
)

listener.ora file

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /home/oracle/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = mytest)
(ORACLE_HOME = /home/oracle/oracle/product/10.2.0/db_1)
(SID_NAME = mytest)
)
(SID_DESC =
(SID_NAME = mydb)
(ORACLE_HOME = /home/oracle/oracle/product/10.2.0/db_1)
(SID_NAME = mydb)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
)
)

Step 2: create pfile for target database from source database

SQL> create pfile from spfile;

File created.

Step 3: modified parameter file for target database (duplicate) here log_file_name_convert and db_file_name_convert and control file location is important, further your choice.

*.audit_file_dest=’/home/oracle/oracle/product/10.2.0/db_1/admin/mydb/adump’
*.compatible=’10.2.0.1.0′
*.db_block_size=8192
*.db_domain=”
*.db_file_multiblock_read_count=16
*.db_name=’mydb’
*.control_files=’/home/oracle/oracle/product/10.2.0/oradata/mydb/control01.ctl’,'/home/oracle/oracle/product/10.2.0/oradata/mydb/control02.ctl’,'/home/oracle/oracle/product/10.2.0/oradata/mydb/control03.ctl’
*.db_file_name_convert=’/home/oracle/oracle/product/10.2.0/db_1/oradata/mytest’,'/home/oracle/oracle/product/10.2.0/oradata/mydb’
*.log_file_name_convert=’/home/oracle/oracle/product/10.2.0/db_1/oradata/mytest’,'/home/oracle/oracle/product/10.2.0/oradata/mydb’
*.db_recovery_file_dest=’/home/oracle/oracle/product/10.2.0/db_1/flash_recovery_area’
*.db_recovery_file_dest_size=2147483648
*.dispatchers=’(PROTOCOL=TCP) (SERVICE=mydbXDB)’
*.job_queue_processes=10
*.open_cursors=300
*.pga_aggregate_target=94371840
*.processes=150
*.remote_login_passwordfile=’EXCLUSIVE’
*.sga_target=285212672
*.undo_management=’AUTO’
*.undo_tablespace=’UNDOTBS1′

Step 4: Create password file

[oracle@localhost ~]$orapwd file=orapwmydb password=oracle entries=5

Step 5: start your target database nomount stage

[oracle@localhost ~]$ export ORACLE_SID=mydb
[oracle@localhost ~]$ rlwrap sqlplus

Roll Forward Physical standby database in 12c

As you are aware that rolling forward a physical standby via an incremental SCN backup method is the simplest method of getting your standby database with lag into sync with the primary database. The lag can be due to missing archives on the primary which haven’t been shipped or applied on the standby.

 

With 12c, the roll forward technique is a bit different. In the prior versions, we had to initially take an incremental backup of the primary database from the SCN where the…
