Vou simular agora a cria\u00e7\u00e3o de um novo PDB, e constatar que automaticamente um servi\u00e7o \u00e9 criado pelo processo de background LREG:<\/p>\n\n\n

Por\u00e9m a cria\u00e7\u00e3o do servi\u00e7o pode demorar at\u00e9 60 segundos. No meu exemplo, o mesmo j\u00e1 foi criado e \u00e9 apresentado conforme abaixo:<\/p>\n\n\n

Caso queiramos registrar o servi\u00e7o de maneira pontual podemos executar o comando abaixo:<\/p>\n\n\n

Podemos consultar os servi\u00e7os pela query abaixo:<\/p>\n\n\n

Para conectarmos neste novo PDB, podemos fazer via easy connect:<\/p>\n\n\n
