Step by Step clone of an Oracle 10g using RMAN

Applies to:

Oracle Server – Enterprise Edition – Version: 10.2.0.1.0 – 64 bit to 10.2.0.3.0 – 64 bit.
Information in this document applies to any platform.

Goal:

This document gives a step by step guide about how to clone an Oracle database to a different host using RMAN.

Solution:

1- Create a new Database with a new instance. X06 is the auxiliary database.
2- Create a new table space named “REPOSITORY_FOR_RMAN” on X06;

CREATE TABLESPACE “REPOSITORY_FOR_RMAN”
LOGGING
DATAFILE ‘/u01/app/oracle/oradata/X06/REPOSITORY_FOR_RMAN.dbf’ SIZE 100M EXTENT MANAGEMENT LOCAL
SEGMENT SPACE MANAGEMENT AUTO
;

3- Create an Oracle user rman on X06 ;
create user rman identified by wissem default tablespace REPOSITORY_FOR_RMAN
temporary tablespace temp
quota unlimited on REPOSITORY_FOR_RMAN;

4- Grant to rman user on X06 with all the privileges to perform backup and recovery actions;
grant connect, resource, recovery_catalog_owner to rman;

5- We must be sure that the following variables are setup correctly on X06 :

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/oracle/product/10.2.0/x06/oracle
export ORACLE_SID=X06

6- Create a recovery manager catalog on X06 :

cd $ORACLE_HOME/bin

[oracle@x06 bin]$ ./rman catalog rman/wissem

Recovery Manager: Release 10.2.0.1.0 – Production on Wed Jun 30 11:55:53 2010

Copyright (c) 1982, 2005, Oracle. All rights reserved.

connected to recovery catalog database

RMAN> create catalog tablespace REPOSITORY_FOR_RMAN;

recovery catalog created

RMAN>

7- Add the following entry in your TNSNAMES.ORA: DEVTARGET.ES.EDWN.LAN is our target database.

[oracle@x06 admin]$ pwd
/u01/app/oracle/oracle/product/10.2.0/x06/oracle/network/admin
[oracle@x06 admin]$ cat tnsnames.ora
DEVTARGET.ES.EDWN.LAN =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = Devtarget.es.edwn.lan)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = Devtarget.es.edwn.lan)
)
)

8- Test the connection to the target database:

[oracle@x06 admin]$ sqlplus

SQL*Plus: Release 10.2.0.1.0 – Production on Wed Jun 30 11:58:07 2010

Copyright (c) 1982, 2005, Oracle. All rights reserved.

Enter user-name: sys@DEVTARGET.ES.EDWN.LAN as SYSDBA
Enter password:

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 – 64bit Production
With the Partitioning, OLAP and Data Mining options

9- Register the target database with the recovery manager catalog:

[oracle@x06 admin]$ $ORACLE_HOME/bin/rman target sys@DEVTARGET.ES.EDWN.LAN

Recovery Manager: Release 10.2.0.1.0 – Production on Wed Jun 30 11:59:58 2010

Copyright (c) 1982, 2005, Oracle. All rights reserved.

target database Password:
connected to target database: DEVTARGET (DBID=1826617959)

RMAN>

RMAN> connect catalog rman/wissem@X06.D15.LAN

connected to recovery catalog database

RMAN> register database;

database registered in recovery catalog
starting full resync of recovery catalog
full resync complete

RMAN> CONNECT AUXILIARY SYS/wissem@X06.D15.LAN

connected to auxiliary database: X06 (DBID=329306800)

RMAN>

10- No mount the auxiliary database X06. Target database still in open mode.

SQL> startup force nomount;
ORACLE instance started.
Total System Global Area 1258291200 bytes
Fixed Size 2020448 bytes
Variable Size 318770080 bytes
Database Buffers 922746880 bytes
Redo Buffers 14753792 bytes
SQL>

11- Connect to the target database using Recovery manager pointed at the auxiliary database :

[oracle@x06 admin]$ $ORACLE_HOME/bin/rman target sys@DEVTARGET.ES.EDWN.LAN AUXILIARY /

Recovery Manager: Release 10.2.0.1.0 – Production on Wed Jun 30 15:36:03 2010

Copyright (c) 1982, 2005, Oracle. All rights reserved.

target database Password:
connected to target database: DEVTARGET (DBID=1826617959)
connected to auxiliary database: X06 (not mounted)

12- Make a whole backup of the target database using RMAN : (Target database is open)

[oracle@x06 admin]$ $ORACLE_HOME/bin/rman target sys@DEVTARGET.ES.EDWN.LAN

Recovery Manager: Release 10.2.0.1.0 – Production on Wed Jun 30 15:43:23 2010

Copyright (c) 1982, 2005, Oracle. All rights reserved.

target database Password:
connected to target database: DEVTARGET (DBID=1826617959)

RMAN> BACKUP DATABASE;

Starting backup at 30-JUN-10
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1

13- Make the clone :

[oracle@x06 admin]$ $ORACLE_HOME/bin/rman target sys@DEVTARGET.ES.EDWN.LAN AUXILIARY /
Recovery Manager: Release 10.2.0.1.0 – Production on Wed Jun 30 15:36:03 2010
Copyright (c) 1982, 2005, Oracle. All rights reserved.
target database Password:
connected to target database: DEVTARGET (DBID=1826617959)
connected to auxiliary database: X06 (not mounted)
