clone oracle database in 11g:
------------------------------
Reading the http://docs.oracle.com/cd/E11882_01/backup.112/e10643/rcmsynta020.htm URL is advisable before one attempt to do cloning the oracle database. This is my view.
As you all know that there are two simplest methods to clone the db
1. active database duplication (source should be available)
2. backup based database duplication (using source backup files, connection to source db is optional)
The following method shows the first way of doing clone the database - active database duplication
Source db is in archivelog and have a valid backup (RMAN> backup database plus archivelog delete input;)
Sys password should be same on both source and target
Requirement is to clone the orcl database to destination clonedb1 db on same host on windows 7
1. Add entry into lsnrctl.ora and tnsnames.ora network config files.
Target database: clonedb1
lsnrctl.ora:
----------------
(SID_DESC =
(GLOBAL_DBNAME=CLONEDB1)
(SID_NAME = CLONEDB1)
(ORACLE_HOME = F:\app\HOME\product\11.2.0\dbhome_1)
)
complete: lsnrctl.ora file
# listener.ora Network Configuration File: F:\app\HOME\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = F:\app\HOME\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:F:\app\HOME\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME=CLONEDB1)
(SID_NAME = CLONEDB1)
(ORACLE_HOME = F:\app\HOME\product\11.2.0\dbhome_1)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)
ADR_BASE_LISTENER = F:\app\HOME
tnsnames.ora
----------------
CLONEDB1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = CLONEDB1)
)
)
tnsnmaes.ora file:
# tnsnames.ora Network Configuration File: F:\app\HOME\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
CLONEDB1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = CLONEDB1)
)
)
2. create service and start the service
C:\Users\HOME>
C:\Users\HOME>oradim -delete -sid clonedb1
Instance deleted.
C:\Users\HOME>oradim -new -sid clonedb1 -intpwd password=oracle -startmode a -pf
ile D:\TESTDELETE\initclonedb1.ora
OPW-00005: File with same name exists - please delete or rename
Instance created.
3. Create password file
C:\Users\HOME>orapwd file=F:\app\HOME\product\11.2.0\dbhome_1\database\PWDcloned
b1.ora password=oracle entries=50
4. Create pfile from source db
login soruce db:
C:\Users\HOME>SET ORACLE_SID=ORCL
C:\Users\HOME>sqlplus "/as sysdba"

C:\Users\HOME>set ORACLE_SID=ORCL
alter system set db_recovery_file_dest_size=5G;
Ensure the above statement is run with sufficent disk space for db_recovery_File_Desk_size on both source and target db.
tnsping orcl
tnsping clonedb1
Ensure that the above both commands give valid output in source system... it means you are able to connect both databases and able to do successfull clone in upcoming steps...
