Klonopin Price Este artigo tem como objetivo demonstrar como clonar um pluggable database no banco de dados 12c no mesmo container root do mesmo servidor.
Para clonar é muito simples, basta ter área disponível no storage para a criação que o Oracle automaticamente criará o clone.

follow url Vamos verificar os PDBs.

https://www.anonpr.net/a64nihowg1 Vamos clonar o PDB “TOMIASI” para um outro de teste “TOMIASI_DBTESTE”.
Para clonar o PDB, podemos realizar de 2 maneiras:
– Colocar o PDB que irá ser clonado em modo Read Only, porém antes devemos fechá-lo.
– Ou usar o comando “force”, ele altera o status do PDB e ainda mante os usuários conectados.
Comando a ser executado com force:

go alter pluggable database TOMIASI open read only force;

No exemplo abaixo, utilizei a primeira opção:
Segue abaixo os passos:

source url Vamos criar o clone do PDB “TOMIASI”. Tendo área suficiente, basta executar o comando abaixo.

source link Criado o PDB “TOMIASI_DBTESTE” vamos abrir o PDB “TOMIASI” e verificar como que ficou os PDBs.

see url Podemos perceber que o PDB “TOMIASI_DBTESTE” está montado. Vamos abrir o mesmo.

https://www.psychiccowgirl.com/98xqr7e9rm Após criado e aberto o “TOMIASI_DBTESTE”, podemos conforme abaixo verificar os PDBs estão registrados no Listener.
OBS: Quando se cria o PDB, o mesmo é registrado no Listener automaticamente.

http://jannaorganic.co.uk/blog/2025/04/03/tokzoex4 Para acessar O PDB “TOMIASI_DBTESTE” com Oracle Net Directory Naming devemos adicionar o mesmo ao TNSNAMES conforme abaixo.
Vamos visualizar o atual TNSNAMES.
