Insights and Strategies for DBA

10G Same Machine But Different Directories

create a directory to the destination location like

Source Directory D:\oracle\product\10.2.0\oradata\orcl
DBNAME: ORCL

Destination Directory E:\orcld\
DBNAME: ORCLD
bdump
cdump
adump
udump
Archive
flash_recovery_area

-----Source:-----
create pfile from spfile;

rman target 'sys/oracle@orcl'
backup database plus archivelog;

-----Destination-----
change the dbname & destination in pfile

create a service of destination database ORCLD
oradim -new -sid orcld -startmode manual -initpwd oracle

listener & services create

sqlplus sys/oracle@orcld as sysdba
create spfile from pfile=' ';
startup nomount

rman target 'sys/oracle@orcl' nocatalog auxiliary='sys/oracle@orcld'
duplicate target database to orcld;

========================================================================

Without Connection To Target DataBase like(not tns configure etc.)
Clone Two Different Machine But Both Side Are Same Platform

In linux create NFS first because same location backup.

I'll give you small demontration on
1st Windows Server 2003 (192.168.xx.1) DBNAME: orcl
2nd Windows XP (192.168.xx.2) DBNAME: orcld

1.) Create full database on 1st machine with all setup listener & services
Some command perform its recommend because of any accident
alter database backup controlfile to tace as 'D:\Control.txt' ;
create pfile='D:\initorcl.ora' from spfile;

rman target 'sys/oracle@orcl'
configure channel device type disk format 'D:\Backup\%d_%U';
backup database;
sql 'alter system archive log current';
backup archivelog all;
backup current controlfile;
list backup

copy (D:\Backup) directory with backup & paste on target machine (D:\)
i.e 1st machine to 2nd machine location & same directory move the backup.

Configure 2nd machine service connection on 1st machine.

2.) Go 2nd machine
create a Pfile and change the location of some directories

Destination Directory E:\orcld\
DBNAME: ORCLD
bdump
cdump
adump
udump
Archive
flash_recovery_area

set two parameter in pfile its must
*.db_file_name_convert=('d:\oracle\product\10.2.0\oradata\orcl\','e:\orcld\')
*.log_file_name_convert=('d:\oracle\product\10.2.0\oradata\orcl\','e:\orcld\')

create a service of destination database ORCLD
oradim -new -sid orcld -startmode manual -initpwd oracle

Configure Listener & service

set oracle_sid=orcld
sqlplus sys/oracle@orcld as sysdba
create spfile from pfile='E:\initorcld.ora';
startup nomount

3.) 1.st machine
rman target 'sys/oracle@orcl' nocatalog auxiliary 'sys/oracle@orcld'
duplicate target database to orcld;

Enjoy with rman cloning.........?

Unix system:

set IP source and target
vim /etc/host
192.168.xx.xx source.com source
192.168.xx.xx target.com target

· Creating initialization Parameter file for the Duplicate database

If you are using spfile then only parameter required for the duplicate database is DB_NAME. Rest other parameters can be set in the duplicate command itself. If you are not using the spfile , then you need to set initialization parameters in the pfile.

Required parameters:

DB_NAME

CONTROL_FILES

DB_BLOCK_SIZE

DB_FILE_NAME_CONVERT

LOG_FILE_NAME_CONVERT

We will create a pfile with the above parameters for the duplicate database.Create an Oracle Password File for the Duplicate database.

I will make the Duplicate database name as “DUP”

Password file is must for the Active database duplication where as it is not required for backup-based duplication. For Active database duplication it connects directly to the auxiliary instance using the password file with the same SYSDBA password as target database. In case you are using password file make sure to have same SYSDBA password as the target database. In this case, RMAN copies the source database password file to the destination host and overwrites any existing password file for the auxiliary instance.

cd $ORACLE_HOME/dbs

orapwd password=ORCL file=orapwDUP

· Establish Oracle Net Connectivity to the Auxiliary Instance

Auxiliary instance must be available through Oracle Net if you are duplicating from an ACTIVE database.

Add following entries into listener.ora file.

Edit the listener.ora and add following lines:

SID_LIST_LISTENER =

(SID_LIST =

)

(SID_DESC =

(SID_NAME = dup)

(ORACLE_HOME = =/home/oracle/app/oracle/product/11.2.0/dbhome_1)

(GLOBAL_DBNAME = dup.localdomain)

)

Add the Following entry in the tnsnames.ora

prd =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = prd)

)

dup =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = dup)

)

· Create the directories which are required for the duplicate database.

mkdir -p /home/oracle/app/oracle/oradata/dup

mkdir -p /home/oracle/app/oracle/fast_recovery_area/dup

mkdir -p /home/oracle/app/oracle/admin/dup/pfile

· Create the parameter file (initdup.ora).

DB_NAME=dup

diagnostic_dest='/home/oracle/app/oracle'

DB_FILE_name_CONVERT=('/home/oracle/app/oracle/oradata/prd','/home/oracle/app/oracle/oradata/dup')

LOG_FILE_NAME_CONVERT=('/home/oracle/app/oracle/oradata/prd','/home/oracle/app/oracle/oradata/dup')

Memory_TARGET=262144000

CONTROL_FILES='/home/oracle/app/oracle/oradata/dup/control01.dbf'

COMPATIBLE= 11.2.0.0.0

· Start the Auxiliary instance from Sqlplus

Use SQL*Plus to connect to the auxiliary instance using the above created pfile and start it in NOMOUNT mode.

[oracle@localhost admin]$ export ORACLE_SID=dup

[oracle@localhost admin]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Fri Mar 1 12:40:21 2013

Finished Duplicate Db at 01-MAR-13

Duplicate database is successfully created.

NOTE: If You are not connect to target node and no catalog database use the following some step

– CREATE PFILE FROM SOURCE DATABASE

SQL>CREATE PFILE=’/home/oracle/stage/initsource.ora’ FROM SPFILE;

*****************

on the target host.

*****************

– Make a staging folder for backups and pfile

oracle@dest$mkdir -p /home/oracle/stage

– create other required folders

$mkdir -p /u01/app/oracle/oradata/orclt

mkdir -p /u01/app/oracle/flash_recovery_area/orclt

mkdir -p /u01/app/oracle/admin/orclt/adump

mkdir -p /u01/app/oracle/admin/orclt/dpdump

– Copy backup files from the source host

# scp source:/home/oracle/stage/*.bak /home/oracle/stage/

– Copy pfile of source database (orcl)

# scp source:/home/oracle/stage/initsource.ora /home/oracle/stage/inittarget.ora

– Copy the password file as well

$ scp /u01/app/oracle/product/11.2.0/db_1/dbs/orapworcl /u01/app/oracle/product/11.2.0/db_1/dbs/orapworclt

– Add a line in the file /etc/oratab to reflect the database instance you are going to copy:

orclt:/u01/app/oracle/product/11.2.0/db1:N

– Edit the initialization parameter file from the main database.

$vi /home/oracle/stage/inittarget.ora

DB_NAME

CONTROL_FILES

DB_BLOCK_SIZE

DB_FILE_NAME_CONVERT

LOG_FILE_NAME_CONVERT

– Now set the Oracle SID as the duplicated database SID:

$ . oraenv

ORACLE_SID = [orclt] ?

– Startup the target database in nomount mode using modified parameter file

$sqlplus sys/oracle as sysdba

SQL> startup nomount pfile=’/u01/app/oracle/oradata/orclt/inittarget.ora';

create spfile from pfile=’/u01/app/oracle/oradata/orclt/inittarget.ora';

- Using RMAN connect to the duplicate database (orclt) as auxiliary instance

$. oraenv

orclt

$rman auxiliary /

– duplicate the database orcl to orclt

– the command performs the following steps:

* Creates an SPFILE

* Shuts down the instance and restarts it with the new spfile

* Restores the controlfile from the backup

* Mounts the database

* Performs restore of the datafiles. In this stage it creates the files in the

converted names.

* Recovers the datafiles up to the time specified and opens the database

– If duplicate database has the same directory structure as source (on a different host)

RMAN>duplicate target database to orclt backup location ‘/home/oracle/stage/’ nofilenamecheck;

– If duplicate database has different directory structure from source

RMAN>duplicate target database to orclt backup location ‘/home/oracle/stage/’ ;

– check that duplicate database is up

$sqlplus / as sysdba

sql>conn hr/hr

select * from tab;

– Note that DBID is different from the main database so it can be backed up

independently and using the same catalog as well.

SQL> select dbid from v$database;

conn sys/oracle@orcl as sysdba

select dbid from v$database;
