Vamos ver o oitavo exemplo 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 8: Duplicando PDBs - Duplicate de tablespaces PDBs
RMAN permite duplicar não só o CBD, mais também você pode duplicar um ou vários PDBs no mesmo comando de DUPLICATE. Além disso, você pode duplicar um conjunto de tablespaces dentro de um PDB. Você precisa estar logado no root do CDB com um usuário que é concedido o privilégio SYSDBA ou SYSBACKUP. A partir disso, você vai ver exemplos de duplicate do Pluggable Databases (PDBs). As opções para duplicar os PDBs são apresentados abaixo:


Opção do DUPLICATE

Explicação

PLUGGABLE DATABASE pdb_name

Duplica os PDBs específicos do CDB. Use uma lista delimitada por vírgula para duplicar vários PDBs.

SKIP PLUGGABLE DATABASE pdb_name

Duplica todos os PDBs do CDB, exceto os especificados pelo PDBs pdb_name. Use uma lista delimitada por vírgula para especificar vários PDBs que devem ser excluídos.

TABLESPACE pdb_name:tablespace_name

Duplica os tablespaces especificado dentro de um PDB. O nome do tablespace deve ser prefixado com o nome do PDB que contém o tablespace. Se você omitir o nome do PDB, a raiz é tomado como padrão.

SKIP TABLESPACE pdb_name:tablespace_name

Duplica todos os tablespace do CDB, exceto os tablespaces especificados no PDB especificado.


No exemplo a seguir, estamos trabalhando inicialmente no CDB chamado "prmcdb" como fonte de dados a ser duplicado para o CDB "dupcdb", como fizemos em outra parte deste artigo. Antes de realizar o duplicate, vamos criar um novo tablespace nos PDBs prmpdb01 e prmpdb02. Os tablespaces PDB01_TBS1 e PDB01_TBS2 criados no PDB prmpdb01 e os tablespaces PDB02_TBS1 e PDB02_TBS2 serão criados no PDB prmpdb02.

Neste caso vamos duplicar o PDB01_TBS1 do PDB prmpdb01. Vamos duplicar com o comando do RMAN, com a opções que se segue:


Opção do Duplicate

TABLESPACE - tablespace prmpdb01:pdb01_tbs1

Tipo do Duplicate

Active Database Duplication

Método do Duplicate

Pull-Based

Usando o tipo de backup

BACKUPSETS   (padrão)

Números de Target Channels

1   (padrão)

Números de Auxiliary Channels

1  (padrão)


Usamos o comando duplicate do RMAN nesse caso, com as seguintes opções:               

duplicate database to dupcdb tablespace prmpdb01:pdb01_tbs1
  from active database 
  spfile 
parameter_value_convert  ='prmcdb','dupcdb' 
set db_file_name_convert  ='prmcdb','dupcdb'
set log_file_name_convert ='prmcdb','dupcdb';

Descrição do código:
Como se vê a partir do código acima, o RMAN irá duplicar o tablespace pbd01_tbs1 do PDB prmpdb01. O RMAN duplica somente o PDB prmpdb01, exclui todos os outros PDBs e duplica somente o específico tablespace, ignorando todos os outros do PDB. os target e auxiliary channels não são alocados de forma explícita. O RMAN aloca apenas um target e um default auxiliary channel (ORA_ DISK_1 and ORA_AUX_DISK_1). O número de target e auxiliary channels são os mesmos. Isso significa que nesse caso o RMAN utilizará o método Pull-Based para o duplicate. 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.

No output podemos ver um processo normal de duplicate, como sempre foi nas versões anteriores.

Vamos ver este código em ação:
