Shulou(Shulou.com)06/01 Report--

This example tests that ORACLE 11g uses rman to replicate the database. 11g RMAN duplicate can be realized by Active database duplicate and Backup-based duplicate. The test here uses Backup-based duplicate.

Apply the scenario. Reference http://hbxztc.blog.51cto.com/1587495/1872754 based on Active database duplicate

1. The old library or network is not available, but there is a backup

Experimental environment:

Target db:

Ip 192.168.56.10

Oracle_sid=mydb

Oracle_version=11.2.0.3

Auxiliary db:

Ip 192.168.56.150

Oracle_sid=oradu

Oracle_version=11.2.0.3

1. Backup target db

RMAN > backup database include current controlfile plus archivelog delete all input

2. Copy parameter files and create password files

-- the passwords of target DB and auxiliary DB must be kept consistent. Here, I directly copy the password file of target db to the corresponding directory of auxiliary db.

-- execute on target db

[oracle@localhost ~] $cd $ORACLE_HOME/dbs

[oracle@localhost dbs] $scp orapwmydb oracle@192.168.56.150:/home/oracle

Oracle@192.168.56.150's password:

Orapwmydb 100% 1536 1.5KB/s 00:00

[oracle@localhost dbs] $scp initmydb.ora oracle@192.168.56.150:/home/oracle

Oracle@192.168.56.150's password:

Initmydb.ora 100% 193 0.2KB/s 00:00

3. Copy the backup of the old machine to the corresponding directory on the new machine

[oracle@localhost dbs] $scp / u01/app/oracle/product/11.2.0/db/dbs/34r0vd8l_1_1 oracle@192.168.56.150:/home/oracle/bak

Oracle@192.168.56.150's password:

34r0vd8l_1_1 100% 5457KB 5.3MB/s 00:00

[oracle@localhost dbs] $scp / u01/app/oracle/product/11.2.0/db/dbs/35r0vd8m_1_1 oracle@192.168.56.150:/home/oracle/bak

Oracle@192.168.56.150's password:

35r0vd8m_1_1 100% 1049MB 15.0MB/s 01:10

[oracle@localhost dbs] $scp / u01/app/oracle/product/11.2.0/db/dbs/36r0vdad_1_1 oracle@192.168.56.150:/home/oracle/bak

Oracle@192.168.56.150's password:

36r0vdad_1_1 100% 9952KB 9.7MB/s 00:00

[oracle@localhost dbs] $scp / u01/app/oracle/product/11.2.0/db/dbs/37r0vdag_1_1 oracle@192.168.56.150:/home/oracle/bak

Oracle@192.168.56.150's password:

37r0vdag_1_1 100% 10KB 10.0KB/s 00:00

4. Change the name of the password file, the file name of the parameter file and the corresponding instance name in the parameter file (no need to execute when the instance name remains the same)

Add directory conversion parameters to the parameter file (not needed when the instance name and directory remain the same)

The updated instance in this lab is named oradu

[oracle@localhost ~] $mv initmydb.ora initoradu.ora

[oracle@localhost ~] $mv orapwmydb orapworadu

Vi initoradu.ora changed all the old instance names mydb to oradu and added the conversion parameters

Db_file_name_convert= ('/ u01Accord oradataPlacement')

Log_file_name_convert= ('/ u01Accord oradataPlacement')

Create a new directory

Mkdir-p / u01/app/oracle/oradata/oradu/

You only need to create a new directory without changing the instance name.

Mkdir-p / u01/app/oracle/oradata/mydb/

Move parameter files and password files to the default directory / u01/app/oracle/product/11.2.0/db/dbs/

[oracle@localhost ~] $mv initoradu.ora / u01/app/oracle/product/11.2.0/db/dbs/

[oracle@localhost ~] $mv orapworadu / u01/app/oracle/product/11.2.0/db/dbs/

5. Boot to nomount

[oracle@localhost ~] $export ORACLE_SID=oradu

[oracle@localhost ~] $sqlplus / as sysdba
