Vamos ver nono 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.

Case 9: Duplicando PDBs – Duplicando um PDB e um tablespace em outro PDB
No exemplo a seguir, estamos trabalhando inicialmente no CDB chamado "prmcdb" como fonte de dados a ser duplicado para o CDB "dupcdb", como está em outras parte dessa série de artigos. Nosso database fonte, o CDB prmcdb é apresentado abaixo:

[oracle@oel62-ora12c-prm ~]$ export  ORACLE_SID=prmcdb

Como se vê a partir da saída do código acima, no nosso CDB fonte prmcdb, tem dois PDBs, o prmpdb01 e o prmpdb02. Os tablespaces PDB01_TBS1 e PDB01_TBS2 são criados no PDB prmpdb01 e os tablespaces PDB02_TBS1, PDB02_TBS2 são criados no PDB prmpdb02. Se você não criou os tablespaces no PDBs, então você pode usar o script do tablespace de Caso 8 na parte IX desta série de artigos.

Neste caso, vamos duplicar o PDB prmpdb01 e um tablespace PDB02_TBS2 do PDB prmpdb02. Usamos para isso, o comando duplicate com as opções abaixo:


Opção do Duplicate

PDB and Tablespace - pluggable database prmpdb01 tablespace prmpdb02:pdb02_tbs2

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, como apresentado abaixo:

duplicate database to dupcdb pluggable database prmpdb01 
                             tablespace prmpdb02:pdb02_tbs2 
  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 duplica o PDB prmpdb01 e o tablespace PDB02_TBS2 do PDB prmpdb02. O RMAN duplica o PDB prmpdb01 com todos os tablespaces e o PDB prmpdb02 mais com apenas um específico tablespace. Em outras palavras, o RMAN pula outros tablespaces no duplicatado PDB prmpdb02. 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:

Como se vê no ouput acima, o PDB prmpdb01 duplica todos os tablespaces, já o PDB prmpdb02 duplica apenas o tablespace PDB02_TBS2.
