Vamos ver o segundo dos exemplos para a duplicar o bancos de dados com o RMAN em modo ativo.

Antes de ler este artigo, aconselhamos a ler (parte I) desta série de artigos para que você possa ter certeza sobre a teoria relacionada com esta série de artigos. Se você preparou seu hosts de destino como mostra os 7 passos (na parte I), então você pode duplicar banco de dados usando o RMAN.

Caso 2: Duplicando CDB- Usando Backup Sets comprimidos para executar um Active Database Duplication

No exemplo a seguir, estamos trabalhando inicialmente no CDB chamado "prmcdb" como fonte de dados a ser duplicado para o CDB "dupcdb", como na segunda parte dessa série de artigos. Você pode ver os detalhes da conexão quando o "prmcdb" é estabelecida como "target", você pode observar também a conexão ao banco de dados "dupcdb" como "auxiliary". Usamos o comando duplicate do RMAN com as seguintes opções:


Opção do Duplicate

CDB

Tipo do Duplicate

Active Database Duplication

Método do Duplicate

Pull Based

Usando o tipo de backup

Compressed Backupsets

Números de Target Channels

1

Números de Auxiliary Channels

2


O comando duplicate do RMAN nesse caso é apresentado abaixo:

RMAN>run
{
allocate channel c1 device type disk;
allocate auxiliary channel a1 device type disk;
allocate auxiliary channel a2 device type disk;
 
duplicate target database to dupcdb 
from active database 
spfile 
parameter_value_convert ='prmcdb','dupcdb' 
set db_file_name_convert  ='prmcdb','dupcdb'
set log_file_name_convert ='prmcdb','dupcdb'
using compressed backupset;
}

Descrição do código:  
Este código é um pouco diferente do código na parte II. O RMAN utiliza o COMPRESSED BACKUPSETS para duplicar o banco de dados de origem. Usando os backup sets comprimidos minimiza o tamanho dos backup sets e assim, proporciona um melhor desempenho para a duplicar os dados. Neste caso, o número de target channels (1) é menor do que os auxiliary channels (2), assim, tendo como comportamento a execução do active database duplication utilizando o método Pull-Based. Utilizamos também o parâmetros parameter_value_convert e o db{log}_file_name_convert no comando duplicate. O uso desses parâmetros estão explicados na primeira parte (parte I) desta série de artigos.

 
Vamos ver este código em ação:
