RMAN Restore on another machine with different file system - same database name

RMAN Restore on another machine with different file system - same database name

Primary/Target Machine ITLINUXDEVBLADE08
Secondary/Auxiliary Machine ITLINUXDEVBLADE07
Database Name OPSDBA

Note
For this example, we will be using TSM in order to backup and duplicate the database to the new
machine.Hence TSM needs to be configured on both the machines.
If you are using a disk backup solution and duplicate to a remote node you must first copy
the backupsets from the original hosts backup location to the same mount and path on the remote server.
Because duplication uses auxiliary channels the files must be where the IO pipe is allocated. So the
IO will take place on the remote node and disk backups must be locally available.

Configure the listener.ora on the auxilary machine and the tnsnames.ora on both the machines.
Listener.ora
=============
PRIMARY_OPSDBA =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = itlinuxdevblade07.hq.emirates.com)(PO
RT = 1527))
)
)
)

SID_LIST_PRIMARY_OPSDBA =
(SID_LIST =
(SID_DESC =
(GLOBAL_NAME = OPSDBA)
(ORACLE_HOME = /opt/oracle/product10gpr2)
(SID_NAME = opsdba)
)
)



tnsnames.ora
=============
opsdba = --> Primary database connect string
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = itlinuxdevblade08.hq.emirates.com)(PORT =1527))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = opsdba)
)
)


opsdba_clone = --> New connect string, but same name
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = itlinuxdevblade07.hq.emirates.com)(PORT =1527))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = opsdba)
)
)


Start the listener and make sure your are able to ping to both these entries form both
the machines

opsdba:/opt/oracle>tnsping opsdba

OK (0 msec)


opsdba:/opt/oracle>tnsping opsdba_clone

TNS Ping Utility for Linux: Version 10.2.0.2.0 - Production on 30-JAN-2007 13:53:50

(PORT = 1527)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = opsdba)))
OK (0 msec)


On the auxiliary machine, create the necessary directories for the database.
Copy the parameter file from the target machine to the auxiliary machine and
change the parameters to point to the new directory structure. Changes may be required
for the following entries:
audit_file_dest
background_dump_dest
control_files
core_dump_dest
log_archive_dest_1
user_dump_dest

Make sure the value for parameter remote_login_passwordfile is set to exclusive
remote_login_passwordfile='EXCLUSIVE'

Create the password file for the database.
orapwd file=orapwopsdba password=oracle entries=5

Note
You can use the parameters db_file_name_convert and log_file_name_convert and they will
generate the "set newname for datafile" syntax needed to change the controlfile. These parameters
accommodate up to 5 different file placement locations using:

db_file_name_convert = ('/old/path1', '/new/path1',
'/old/path2', '/new/path2',
'/old/path3', '/new/path3')
log_file_name_convert = ('/old/path1', '/new/path1',
'/old/path2', '/new/path2',
'/old/path3', '/new/path3')


You can also create your own "set newname for datafile" syntax for all your files skipping these
parameters all together. You can still use the log_file_name_convert parameter or you can use the
'logfile' command to specifiy where the logs will be created and what size.
For this exercise, I am doing the hard way, that is creating my own script.


Get the list of datafiles from the target database

SQL > select file#, name from v$datafile;
FILE# NAME
----- --------------------------------
1 /u02/ORACLE/opsdba/system01.dbf
2 /u02/ORACLE/opsdba/undotbs01.dbf

11 /u02/ORACLE/opsdba/drtbs1.dbf
12 /u02/ORACLE/opsdba/drtbs2.dbf
13 /tmp/undonew.dbf




Get the logfile sequence number and status from the target database:
SQL> select SEQUENCE#, status from v$log;

Create the script file as follows:

On the primary machine, connect to RMAN and take a complete backup of the database and
archivelog files.
rman target / catalog rman10/rman10@rman10s

}

After backup is completed we can now proceed with cloning the database.


Connect to both the databases using RMAN and then use the script that we generated earlier.
