Esta seção descreve como configurar seu banco de dados Oracle de origem para que o Datastream possa extrair dados dele. O Datastream pode extrair alterações de um banco de dados Oracle local ou hospedado na nuvem, incluindo o serviço de banco de dados relacional (RDS, na sigla em inglês) da Oracle.
O Datastream pode usar os seguintes métodos para consultar arquivos de registro refazer:
Leitor de registro binário (Pré-lançamento): selecione esse método se você precisar consultar arquivos de registro "redo" on-line e arquivados. O leitor binário pode acessar os arquivos de registro usando o gerenciamento automático de armazenamento (ASM, na sigla em inglês) ou objetos de diretório do banco de dados. Esse método é multithread e oferece suporte a CDC de baixa latência.
API LogMiner: selecione esse método se você só precisar trabalhar com arquivos de registro "redo" arquivados. O Oracle LogMiner é de linha única e pode estar sujeito a maior latência e menor capacidade. No entanto, esse método oferece suporte à maioria dos tipos de dados e recursos do banco de dados Oracle.

Datastream can pull changes to data from on-premises or cloud-hosted Oracle databases, including Oracle relational database service (RDS).\n\nDatastream can use the following methods to query redo log files:\n\n- **Binary log reader** ([Preview](/products#product-launch-stages)): select this method if you need to query both online and archived redo log files. Binary reader can access the log files using Automatic Storage Management (ASM) or database directory objects. This method is multithreaded and supports low-latency CDC.\n\n- **LogMiner API**: select this method if you only need to work with archived redo log files. The Oracle LogMiner is single-threaded and can be subject to higher latency and lower throughput. However, this method supports most data types and Oracle database features.\n\n For more information about these methods, see\n [Overview of Oracle as a source](/datastream/docs/sources-oracle#behavior)\n and [Work with Oracle database redo log files](/datastream/docs/work-with-oracle-database-redo-log-files).\n For information about how to configure your database type for each of these\n methods, see the respective configuration pages.\n\nSupported databases\n-------------------\n\nDatastream works with the following types of Oracle databases:\n\n- Amazon RDS for Oracle\n- Self-managed Oracle database\n- Self-hosted Oracle pluggable database\n\nWhat's next\n-----------\n\n- Learn how to configure an [Amazon RDS for Oracle](/datastream/docs/configure-amazon-rds-oracle) database to work with Datastream.\n- Learn how to configure a [self-managed Oracle database](/datastream/docs/configure-self-managed-oracle) to work with Datastream.\n- Learn how to configure a [self-hosted Oracle pluggable database](/datastream/docs/configure-pluggable-oracle) to work with Datastream."]]
