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/oracle@chicago;   # Primary
connect auxiliary sys/oracle@boston; # 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
