Preperation

As example we will create database ASM453D1 from

source database ASM451D1.

The new database will run on the ota5045

the source database runs on the ota5026

First we create the audit directory on the ota5045

$ mkdir /oracle/home/admin/ASM453D/adump

put new database in /etc/oratab $vi /etc/oratab

ASM453D1:/oracle/home/11.2.0.3.0:N

Then make a pfile with only 1 entry in it.

$ vi $ORACLE_HOME/DBS/initASM453D1.ora

db_name=ASM453D

In our enviroment the listenerer runs under grid user

login as grid user and go to $ORACLE_HOME/network/admin

$ vi listener.ora

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

(ADDRESS = (PROTOCOL = TCP)(HOST =

ota5045.business.finl.fortis)(PORT = 1521))

)

)

SID_LIST_LISTENER =

(SID_LIST =

( SID_DESC =

(GLOBAL_DBNAME = ASM453D)

(ORACLE_HOME = /oracle/home/11.2.0.3.0)

(SID_NAME = ASM453D1)

)

)

Log on as oracle user op de ota5045 an put the following entry's in the tnsnames.ora

ASM451D1 =

(DESCRIPTION =

(ADDRESS_LIST =

(LOAD_BALANCE=ON)

(ADDRESS = (Protocol = TCP)(Host = ota5026)(Port = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = ASM451D)

)

)

ASM453D1 =

(DESCRIPTION =

(ADDRESS_LIST =

(LOAD_BALANCE=ON)

(ADDRESS = (Protocol = TCP)(Host = ota5045)(Port = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = ASM453D)

)

)

Do the same for the tnsnames.ora on the ota5025 where the source database is

running.

copy password file from source database to target database and change name of the

file on the ota5026 as user oracle

$ scp $ORCLE_HOME/dbs/orapwASM451D1 ota5045:$ORACLE_HOME/dbs

$ mv orapwASM451D1 orapwASM453D1

$ chmod 650 orapwASM453D1

start the new database ASM453D1 in nomount fase

SQL> startup nomount

On the ota5026 where the target database ASM451D1 runs start rman and login

connect target sys/password@asm451d

connect auxiliary sys/password@asm453d

Note *

Passwords MUST be the same otherwise the active duplicate fails

Start the duplicate from active database.

duplicate target database

TO ASM453D

from active database

spfile

SET db_file_name_convert 'ASM451D','ASM453D'

SET log_file_name_convert 'ASM451D','ASM453D'

SET control_files

'+DATA/asm453d/controlfile/control1.ctl','+FRA/asm453d/controlfile/control2.ctl'

SET audit_file_dest '/oracle/home/admin/SVM453D/adump';

This are the last lines of the active duplicate.
