Recovery catalog for RMAN

Creating the Recovery Catalog Owner

Start by creating a database schema (usually called rman). Assign an appropriate tablespace to it and grant

it the recovery_catalog_owner role. Look at this example:

% sqlplus '/ as sysdba'

SQL> CREATE USER rman IDENTIFIED BY rman
DEFAULT TABLESPACE tools
TEMPORARY TABLESPACE temp
QUOTA UNLIMITED ON tools;

SQL> GRANT CONNECT, RECOVERY_CATALOG_OWNER TO rman

Creating the Recovery Catalog

% rman catalog rman/rman@ORCL

RMAN> CREATE CATALOG;

Registering the target database

% rman TARGET / CATALOG rman/rman@ORCL

RMAN> REGISTER DATABASE;

# Find Production Database Files:

Create the Auxiliary Database directories needed

cd $ORACLE_HOME/dbs

create parameter file initAUX.ora

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')

eg:-

db_name = aux

db_block_size = 8192

compatible = 10.2.0.1.0

remote_login_passwordfile = exclusive

control_files = ('/newpart/oradata/aux/control01.ctl',

'/newpart/oradata/aux/control02.ctl')

db_file_name_convert = ('/newpart/oradata/orcl',

# create a passwordfile for remote connections as sysdba

% orapwd password= file=orapwAUX

% sqlplus /nolog

SQL> connect / as sysdba

Start the Duplication

ORACLE_SID=AUX; export ORACLE_SID # ksh

sqlplus /nolog

SQL> connect / as sysdba

Connected to an idle instance

SQL> startup nomount pfile=$ORACLE_HOME/dbs/initAUX.ora

SQL> exit

# Set your SID back to the TARGET for duplication.

RMAN> connect target

connected to target database: V10GREL4 (DBID=2510891965)

RMAN>backup database;

RMAN>sql 'alter system switch logfile';

RMAN> connect auxiliary sys/pwd@AUX

connected to auxiliary database: AUX (not mounted)

RMAN> duplicate target database to AUX device type disk;

Once this is done, login to duplicate database with alter database open resetlogs.
