Oracle Server - Enterprise Edition - Version: 11.1.0.6 to 11.1.0.7

Information in this document applies to any platform.

Goal

This note outlines the required steps to create a physical standby database using 11g RMAN DUPLICATE FROM ACTIVE DATABASE. The script. is taken from Data Guard labs based on the 11g OBEs available from OTN.

Solution

Install Oracle on standby system.

Update tnsname.ora on primary & standby systems. In this example, Chicago is Primary and Boston is Standby.

tnsnames.ora (on both systems)

BOSTON =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = lcarpent.us.oracle.com)(PORT = 1521))

)

(CONNECT_DATA = (SERVICE_NAME = Boston.us.oracle.com))

)

CHICAGO =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = stadu67.us.oracle.com)(PORT = 1521))

)

(CONNECT_DATA = (SERVICE_NAME = Chicago.us.oracle.com))

)

Also, insert a static entry for Boston in the listener.ora file of the standby system.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = Boston.us.oracle.com)

(ORACLE_HOME = /scratch/OracleHomes/OraHome111)

(SID_NAME = Boston)

)

)

LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = lcarpent.us.oracle.com)(PORT = 1521))

)

Then execute the following script. on standby, assuming ASM is setup with +DATA and +FLASH disk groups:

source ./makeBoston

# Create temporary password file, must have same password as primary

orapwd file=/scratch/OracleHomes/OraHome111/dbs/orapwBoston password=oracle

# Create temporary parameter file

cat > /scratch/OracleHomes/OraHome111/dbs/tempini.ora < db_name=temp

EOF

# Start up the auxiliary instance nomount

sqlplus '/ as sysdba' < SET ECHO ON

STARTUP PFILE='/scratch/OracleHomes/OraHome111/dbs/tempini.ora' NOMOUNT;

EOF

rman < set echo on

connect target sys/[email protected]; # Primary

connect auxiliary sys/[email protected]; # Standby: tnsname used by primary

run {

allocate channel prmy1 type disk;

allocate channel prmy2 type disk;

allocate channel prmy3 type disk;

allocate channel prmy4 type disk;

allocate channel prmy5 type disk;

allocate auxiliary channel stby1 type disk;

duplicate target database for standby from active database

spfile

parameter_value_convert 'Chicago','Boston'

set 'db_unique_name'='Boston'

set standby_file_management='AUTO'

set db_create_file_dest='+DATA'

set db_recovery_file_dest='+FLASH'

set DB_RECOVERY_FILE_DEST_SIZE='8G'

set dg_broker_start='TRUE'

set control_files='+DATA/boston/controlfile/control01.ctl'

nofilenamecheck

;

}

EOF

exit 0
