Target (source) Host: Red Hat Enterprise Linux Server release 7.2 (Maipo)
Destination Host: CentOS Linux release 7.3.1611 (Core)
DB: 11.2.0.4.0
Target DB Name: maliyye
Destination DB Name: alfamal
Steps 1,2,9,10,12 will be executed from target (source) host.
Steps 3,4,5,6,7,8,11,13,14,15 will be executed from destination host.
1. Create a service for new database(alfamal) in tnsnames.ora file in target host.
[oracle@db admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
maliyye =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 112.100.11.25)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = maliyye)
)
)
stby =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 112.100.11.26)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = stby)
)
)
alfamal =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 112.100.11.31)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =alfamal)
)
)
2. Edit listener.ora file on target host.
[oracle@db admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = db)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=alfamal)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=alfamal)
)
)
ADR_BASE_LISTENER = /u01/app/oracle
And the restart listener: lsnrctl stop, lsnrctl start
3. Install only database software on destination host and create listener with netca.
4. Edit listener file on destination host as
[oracle@alfa admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = alfa)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=alfamal)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=alfamal)
)
)
ADR_BASE_LISTENER = /u01/app/oracle
And the restart listener: lsnrctl stop, lsnrctl start
5. Create a service for new database(alfamal) on destination host
[oracle@alfa admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
maliyye =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 112.100.11.25)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = maliyye)
)
)
alfamal =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 112.100.11.31)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =alfamal)
)
)
6. Add a line in the file /etc/oratab to reflect the new database instance on destination host
alfamal:/u01/app/oracle/product/11.2.0/dbhome_1:N
7. Set environment variables for duplicated database on destination host as
[oracle11g@orcl11g oracle]$ . oraenv
ORACLE_SID = [maliyye] ? alfamal
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1 is /u01/app/oracle
8. Create folders in destination host for duplicated database
[oracle@alfa ~]$ mkdir -p /u01/app/oracle/oradata
[oracle@alfa ~]$ mkdir -p /u01/app/oracle/fast_recovery_area
[oracle@alfa ~]$ mkdir -p /u01/app/oracle/admin/alfamal/adump
[oracle@alfa ~]$ mkdir -p /u01/app/oracle/admin/alfamal/dpdump
9. Create pfile from target (source) database.
SQL> create pfile='$ORACLE_HOME/dbs/initsource.ora' from spfile;
File created.
10. Copy the initialization parameter file from the target (source) database to destination database
oracle11g@orcl11g oracle]$ cp $ORACLE_HOME/dbs/initsource.ora
/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initalfamal.ora
11. Edit the pfile initalfamal.ora as:
*.audit_file_dest='/u01/app/oracle/admin/alfamal/adump'
*.audit_trail='db'
*.compatible='11.2.0.4.0'
*.control_files='/u01/app/oracle/oradata/alfamal/control01.ctl','/u01/app/oracle/fast_recovery_area/alfamal/control02.ctl'
*.db_block_size=8112

*.dispatchers=''
*.log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST'
*.log_archive_max_processes=5
*.open_cursors=300
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.undo_management='AUTO'
*.undo_tablespace='UNDOTBS1'
*.db_create_file_dest='/u01/app/oracle/oradata'
*.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'
db_file_name_convert=("/u01/app/oracle/oradata/maliyye","/u01/app/oracle/oradata/alfamal")
log_file_name_convert=("/u01/app/oracle/oradata/maliyye","/u01/app/oracle/oradata/alfamal")
12. Copy the password file from target to destination host as well
oracle11g@db~]$ cp $ORACLE_HOME/dbs/orapwmaliyye
$ORACLE_HOME/dbs/orapwalfamal
13. Startup the destination database in nomount mode using modified parameter file and create spfile from it.
SQL> startup nomount pfile='/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initalfamal.ora';
ORACLE instance started.

Redo Buffers 20611264 bytes
SQL> sho parameter db_name

----------------- ----------- -----------------------
db_name string alfamal
SQL> create spfile from pfile;
File created.
14. Connect to target and auxiliary instance then duplicate database.
Note: We have to connect auxiliary(destination) database with TNS name. If not duplication will fail.
